The work required to maintain the motion for 16 seconds is 0.16 J.
work = force x distance
In this case, the distance is constant and equal to the horizontal distance covered in 16 seconds, which is 0.1 m/s x 16 s = 1.6 m.
The force required to maintain the horizontal motion at a constant speed is known as the frictional force, which is equal to the force of friction times the normal force. In this case, let's assume the frictional force is 0.1 N.
So the work done in maintaining the horizontal motion for 16 seconds would be:
work = force x distance = 0.1 N x 1.6 m = 0.16 J (joules)
Therefore, the work required to maintain the motion for 16 seconds is 0.16 J.

a plastic balloon that has been rubbed with wool will stick to a wall. can you conclude that the wall is charged? if so, where does the charge come from? if not, why does the balloon stick?
No, it doesn't always imply that the wall is charged because the ball can cling to a non-charged wall.
The effect is caused by static electricity where we have plastic balloons. Static electricity refers to the buildup of electric charge in an item. Static electricity is significant because it may cause items to cling to one another.
This happens when two items with opposing charges, positive and negative, attract one other. Wool is a conductive substance, which means it quickly absorbs electrons as we discuss our dilemma. As a result, pressing a balloon against a wall causes electrons to move from the wool to the balloon's surface.
The rubbed area of the balloon is now negatively charged. Rubber things, such as the balloon, are electrical insulators, which means they hinder the flow of electrical charge through them.

one little of water at 100c is added to four litres of water at 30c.what will be the final temperature of the water?
Answer:
o calculate the final temperature of the water, we can use the formula for heat transfer:
Q = mcΔT
where Q is the heat transfer, m is the mass of the water, c is the specific heat capacity, and ΔT is the change in temperature.
For the one liter of water at 100°C, the heat transfer is:
Q1 = (1 kg) * (4.18 J/g°C) * (100°C - 30°C) = 4180 J
For the four liters of water at 30°C, the heat transfer is:
Q2 = (4 kg) * (4.18 J/g°C) * (100°C - 30°C) = 16680 J
Since heat is conserved, the total heat transfer must remain constant:
Q1 + Q2 = Qfinal
Therefore, the final temperature of the water can be calculated as:
Qfinal = (5 kg) * (4.18 J/g°C) * ΔTfinal
Solving for ΔTfinal, we get:
ΔTfinal = Qfinal / (5 kg) * (4.18 J/g°C) = (Q1 + Q2) / (5 kg) * (4.18 J/g°C) = (4180 J + 16680 J) / (5 kg) * (4.18 J/g°C) = (20860 J) / (5 kg) * (4.18 J/g°C) = 40°C
Therefore, the final temperature of the water will be 40°C.
Explanation:
Answer:
The final temperature of the water will be approximately 46.25°C.
Explanation:
Let's call the initial temperature of the first liter of water T1 = 100°C and the initial temperature of the four liters of water T2 = 30°C.
The total mass of the water is 1 + 4 = 5 liters.
Using the equation of Heat Transfer: Q = mcΔT, where Q is the heat transferred, m is the mass, c is the specific heat capacity of water, and ΔT is the change in temperature, we can calculate the heat transfer from the first liter of water to the four liters of water.
Q = (1 kg) * (4.18 J/g°C) * (100°C - T3)
Q = (4 kg) * (4.18 J/g°C) * (T3 - 30°C)
Solving for T3, we get:
T3 = 46.25°C
So, the final temperature of the water will be approximately 46.25°C.
if the centripetal force on a 3.30 kg object is 14.5n, and the object is 1.90 m from the center of the circle, what is its tangential velocity?
If the centripetal force on a 3.30 kg object is 14.5 N, and the object is 1.90 m from the center of the circle, then the tangential velocity of the object will be 7.50 m/s.
Weight of the object is 3.30 kg ⇒ m = 3.30 kg.
The object is placed 1.90 meter away from the center of the circle and the centripetal force acting on the object will be 14.5 N .
F = 14.5 N and r = 1.90 m.
Centripetal force will be F = m × a = m × v² / r
So, v = sqrt of (F × r / m)
⇒ sqrt (14.5 N × 1.90 m / 3.30 kg) = sqrt (51.85 N × m / kg) = sqrt (51.85 N × m / kg) = 7.50 m/s.
Then the tangential velocity of the object will be 7.50 m/s.

explain how a converging lens could be used to ignite a piece of carbon paper
A converging lens, also known as a positive lens, is a type of lens that has the ability to focus light rays to a single point, known as the focal point. This property can be utilized to ignite a piece of carbon paper.
When using a converging lens to burn carbon paper, care must be taken to position the lens such that sunlight (or another light source) is focused on the paper. As the light is focused, its intensity rises until it eventually reaches a temperature high enough to burn the carbon paper. The lens serves as a magnifying glass in this process, focusing the light beams onto a pinpoint area of the carbon paper and creating heat that eventually ignites the paper.
The size and temperature of the point of ignition will depend on the lens's distance from the paper, its size, and the angle at which the light rays are directed. The "fire by reflection" or "camera obscura" principle refers to this phenomenon. The principle of refraction, which asserts that light changes direction as it passes through various media with differing refractive indices, can be demonstrated in this way.
It is feasible to create a concentrated point of heat hot enough to ignite the carbon paper by employing a converging lens to focus the light.

Group of answer choices
2.8 m
4.5 m
4.2 m
3.7 m
Explanation:
many greetings to your teacher : the question and answer options are wrong.
let's repeat the basic definitions :
Force = mass × acceleration
for a lift the acceleration is going against Earth's gravity : 9.81m/s²
so, we have
F = 25kg × 9.81m/s² = 245.25 N
Work = force × distance
so, we have
W = 245.25 N × 6 m = 1,471.5 J
Power = work / time
so, we have
400 watts = 1,471.5 J / time
time = 1,471.5 J / 400 watts = 3.67875 ≈ 3.7 seconds
so, as you can see, the question has to be "how long did the lift take, when it required 400 watts of power ?"
and the answer is "about 3.7 seconds".
NOT about the distance. that was already defined in the first sentence : 6 m.
without knowing the time duration, no distance can be calculated out of the given data. if we cannot trust the given 6m, then we have one equation with 2 variables (distance and time). that has infinitely many solutions.
Two blocks of masses 3 kg and 5 kg
approach each other with initial velocities 4 m/s and -6 m/s respectively.
The two blocks collide in a totally inelastic collision. What is their common
final velocity after the inelastic collision?
The common final velocity of the two blocks after the inelastic collision is -2.25 m/s.
In a totally inelastic collision, the two objects stick together and move as a single object with a common velocity after the collision. The final velocity of this combined object can be determined using the law of conservation of momentum.
The law of conservation of momentum states that the total momentum of an isolated system remains constant if no external forces act on it. This means that the total momentum of the two blocks before the collision must equal their total momentum after the collision.
The momentum of each block before the collision can be calculated as follows:
m1 * v1 = 3 kg * 4 m/s = 12 kg m/s
m2 * v2 = 5 kg * -6 m/s = -30 kg m/s
The total momentum before the collision is the sum of the individual momenta:
[tex]p_initial = m1 * v1 + m2 * v2 = 12 kg m/s + (-30 kg m/s) = -18 kg m/s[/tex]
After the collision, the two blocks have combined into a single object of mass m1 + m2 = 3 kg + 5 kg = 8 kg. The velocity of this combined object is equal to the final velocity of the collision, which we will call v_final.
The total momentum after the collision is equal to the momentum of the combined object:
[tex]p_final = (m1 + m2) * v_final = 8 kg * v_final[/tex]
Setting p_initial equal to p_final and solving for v_final:
[tex]-18 kg m/s = 8 kg * v_finalv_final = -18 kg m/s / 8 kg = -2.25 m/s[/tex]
So the common final velocity of the two blocks after the inelastic collision is -2.25 m/s.

2.81 A certain volcano on earth can eject rocks vertically to a maximum height H. (a) How high (in terms of H) would these rocks go if a volcano on Mars ejected them with the same initial velocity? The acceleration due to gravity on Mars is 3.71 m/s², and you can neglect air resistance on both planets. (b) If the rocks are in the air for a time T on earth, for how long (in terms of 7) will they be in the air on Mars?
The height of a volcano can reach a maximum of 0.3 times that of Earth, and boulders will float in the air for 0.38 times as long as they did on Earth.
a) When rocks are ejected from a volcano, their initial velocity (V) and the acceleration due to gravity (G) dictate how high they may go (g).
The equation for the greatest height (h) is given by h = V2/. (2g). Gravitational acceleration is 9.8 m/s2 on Earth and 3.71 m/s2 on Mars.
With the same beginning velocity as on Earth, boulders blasted from a volcano on Mars would reach a height of h = V2/(2 * 3.71) = (V2/7.42) m.
On Earth, the maximum height would be 1/7.32 times 1/2.72 times 0.37 times H.
(b) The equation T M = 2V/g may be used to calculate how long the pebbles will remain in the air on Mars (T M).
The equation is T E = 2V/9.8 on Earth and T M = 2V/3.71 on Mars. T M/T E = (2V/3.71) / (2V/9.8) = 3.71/9.8 = 0.38 gives the ratio of the time in the air on Mars to that on Earth.

suppose that one such plate has an average speed of 3.4 cm/yr, assuming the plate maintains the given speed for 1.0 s, how far, in meters, does it move?
Complete Question: Large sections of the Earth's crust called tectonic plates move slowly. How long, in meters, does one of these plates go if its average speed is 3.4 cm/year and it keeps moving at that rate for 1.0 second?
The distance moved by the plate in this case would be [tex]1.08 * 10^-10 m/s * 1.0 s = 1.08 * 10^-10 m.[/tex]
The speed of tectonic plates is measured in centimeters per year (cm/yr), but to find the distance moved in meters, we need to convert the speed to meters per second (m/s). To do this, we first convert the speed to meters per year (m/yr) and then divide by the number of seconds in a year (31,536,000 s/yr).
The average speed of the tectonic plate is 3.4 cm/yr, so the equivalent speed in meters per year is 3.4 cm/yr * 0.01 m/cm = 0.034 m/yr. The speed in meters per second is then 0.034 m/yr / (31,536,000 s/yr) = 1.08 x 10^-10 m/s.
If the plate maintains this speed for 1.0 s, the distance it moves can be calculated using the formula distance = speed x time. The distance moved by the plate in this case would be [tex]1.08 * 10^-10 m/s * 1.0 s = 1.08 * 10^-10 m.[/tex]

If the string's linear density is 0.690 g/m and the tension is 160 N , how long is the vibrating section of the violin string?
The length of the vibrating section of the violin string is approximately 16 cm.
The length of the vibrating section of the violin string can be calculated using the formula for the wavelength of a wave on a string:
λ = 2L / n
where λ is the wavelength, L is the length of the vibrating section of the string, and n is the number of nodes in the vibration.
Next, we can use the formula for the frequency of a wave on a string:
[tex]f = (1 / 2L) * (T / μ)^0.5[/tex]
where f is the frequency, T is the tension in the string, and μ is the linear density of the string.
Combining these two equations and solving for L, we get:

Relativistic momentum is the same as classical momentum at slow speeds. As u moves closer to c, relativistic momentum grows infinitely large. This suggests that a mass-containing item cannot travel at the speed of light. As with classical momentum, relativistic momentum is conserved.
The two types of momentum are linear momentum and angular momentum. The three different types of inertia are inertia at rest, inertia in motion, and inertia in direction. Mass and speed are factors in momentum. An object moving with a velocity has linear momentum, but a spinning object has angular momentum.

how does the temperature dependence of resistance explain the trends you see on the v -i plot for your light bulb? (you do not need to calculate anything here, but give a qualitative answer based on the shape of your v -i plot.)
The resistance decreases with the increasing temperature. The lower the current, the higher the resistance.
What is resistance?Electrical resistance, or resistance to electricity, is a force that opposes the passage of current. In this way, it indicates how difficult the process is for the current to flow. The resistance is measured in ohms.
When there is an electron difference between the two terminals, electricity flows from high to low. That flow is countered by resistance. The lower the current, the higher the resistance. The stronger the current, the lower the resistance. The resistance decreases with the increasing temperature.
Therefore, the resistance decreases with the increasing temperature.
