A helicopter pulls upward by means of a rope on a 250 kg crate to lift it UNIFORMLY. What is the net force on the crate?
Answer:
The net force = 0
Explanation:
The given information includes;
The mass of the crate = 250 kg
The way the helicopter lifts the crate = Uniformly (constant rate (speed), no acceleration)
In order to pull the crate upwards, the helicopter has to provide a force equivalent to the weight of the crate keeping the helicopter on the ground.
The weight of the crate = The mass of the crate × The acceleration due gravity acting on the crate
The weight of the crate, [tex]F_w[/tex]↓ = 250 kg × 9.81 m/s² = 2,452.5 N
The force the helicopter should provide to just lift the crate, [tex]F_{(helicopter)}[/tex]↑ = The weight of the crate = 2,452.5 N
The net force, [tex]F_{(net)}[/tex] = [tex]F_{(helicopter)}[/tex]↑ - [tex]F_w[/tex]↓ = 2,452.5 N - 2,452.5 N = 0
The net force = 0.

To increase power, we need to
Explanation:
To increase power, it is necessary to decrease the work being done and decrease the time in which the work was completed. increase the work being done or decrease the time in which the work is completed.Ma
Answer:
If work is done faster, power is higher. If work is done slower, power is smaller. Since work is force times displacement (W=F*d), and velocity is displacement over time (v=d/t), power equals force times velocity: P = F*v. More power is seen when the system is both strong in force and fast in velocity.

find weight of 45 kg at height 800 km from earth's surface?
Answer:
The weight is 348.4 N
Explanation:
Effect of the Altitude on the Acceleration of Gravity
The effect of gravity decreases with altitude because greater altitudes mean greater distances from the Earth's center.
The practical formula to calculate the gravity as a function of the altitude h is:
[tex]{\displaystyle g_{h}=g_{0}\left({\frac {R_{\mathrm {e} }}{R_{\mathrm {e} }+h}}\right)^{2}}[/tex]
Where go is the conventional gravitational acceleration = [tex]9.80665\ m/s^2[/tex]
R is the Earth's mean radius at the equator = 6,378 Km
h is the altitude.
At a height of h=800 Km, the acceleration of gravity is:
[tex]{\displaystyle g_{h}=9.80665 m/s^2\left(\frac {6,378 Km }{6,378 Km+800Km}}\right)^{2}}[/tex]
Calculating:
[tex]g_h=7.74\ m/s^2[/tex]
The weight is the product of the acceleration of gravity by the mass of the object, thus:
[tex]W=45\ Kg\cdot 7.74\ m/s^2=348.4\ N[/tex]
The weight is 348.4 N
A car starts from rest and accelerates for 2.9 s
with an acceleration of 2 m/s2.
How far does it travel?
Answer in units of m.
Answer:
[tex]a \: = \frac{v - u}{t} [/tex]
2 = v-0/2.9
2× 2.9 = v
v = 5.8 m/s
[tex]v \: = \frac{d}{t} [/tex]
5.8 = d/2.9
5.8×2.9 = d
d = 16.82 m

Describe the nucleus of the atom.
Answer:
The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger Marsden gold foil experiment. Almost all of the mass of an atom is located in the nucleus, with a very small contribution from the electron cloud.
Can an object have a positive position, but a negative velocity? Explain your reasoning.
Answer:
Yes
Explanation:
A position describes the position of an object relative to the x/y-axis (or the four cardinal directions). A velocity is a vector quantity, defining speed with direction.
So if an object is in a positive position, it means they are in the positive x-axis direction (or wherever on the scale the positive values are stated to be) and if it has a negative velocity, it means said object is moving in the opposite direction of the positive x-axis. It is possible for the object to still be in the positive position as it's moving with a negative velocity

A car started its motion from rest and accelerated for 6 seconds, with the acceleration of 4 m/s2. Then it decelerated for 5 seconds, with the acceleration of -1.6 m/s2. What was the velocity of the car after 6+5 seconds?
Answer:
16 m/s
Explanation:
from the formula: a = velocity/time
you calculate the velocity in both cases (when time is 5 sec and 6 sec) by using the formula: velocity = a x time
v (5 sec) =24 m/s
v (6 sec) = - 8 m/s
then : add v (5 sec) to v (6 sec) and the result is 16 m/s
What is the relationship between the tilt of the Earth on its axis, latitude, and temperature?
Answer:
The combination of more direct rays of sunlight and more hours of daylight causes the hemisphere tilted toward the sun to receive more solar radiation and to have warmer temperatures. When the Northern Hemisphere is tilted toward the sun, latitudes between the equator and 90°N (the North Pole) are experiencing summer.

Old thermometers contained very small amounts of mercury. The mercury in the photo has a melting point of −38.8 °C. What can you conclude about the melting point of the mercury in old thermometers?
A. Its melting point can only be determined when the mercury is burned.
B. Its melting point changes as the mercury’s temperature changes.
C. Its melting point equals −38.8 °C because it is mercury.
D. Its melting point is less than −38.8 °C because its volume is smaller.
Answer:
C. Its melting point equals −38.8 °C because it is mercury.
Explanation:
Given that the old thermometer contained a very small amount of mercury and the melting point of mercury is [tex]-30^{\circ}C[/tex].
The temperature at which any material starts changing from the solid-state to the liquid-state is known as the melting point of the material.
As the melting point of any material does not depends on the amount of material. So, whether there is a small amount of mercury or is a large amount of mercury.
Hence, the melting point remains [tex]-30^{\circ}C[/tex] because it is mercury.
So, option (C) is correct.
As per the definition above, there is no need to burn the mercury to determine the melting point, so option (A) is wrong.
The melting point does not depend on the initial temperature, mass, volume of the material, so options (B) and (D) are wrong.

How is acceleration related to force when mass is constant, according to Newton's second law of motion?
Answer:
According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases. This can be shown in the following formula.
[tex]f = ma[/tex]
[tex]a = \frac{f}{m} [/tex]
f = force
m = mass
a = acceleration
According to Newton's second law of motion, acceleration is directly proportional to the force.
What is Newton's second law of motion?According to Newton's second law of motion, an object's change in velocity is influenced by the force being applied to it. An object must accelerate in order to change its velocity. The rate at which an object's velocity alters over time is known as its acceleration.
Since both acceleration and force are vector quantities, the acceleration of an object is determined by the direction of the applied force. How much a net force will alter an object's velocity is described by Newton's second law of motion.
According to Newton's second law of motion, an object's acceleration is directly proportional to the force acting on it.

Where would the net force acting on a charge placed in a system of like charges be zero?
Answer:
If an object is electrically neutral it has no net charge becuase it has the same number of protons as it does electrons, which are opposite charges that offset each other. No, that just means that the sum of all its positive and negative amounts of charge equals zero.
A student is on a skateboard facing a wall. The student and skateboard have a mass of 75 kilograms. The student pushes off of the wall with a force of 100 Newtons. What is the force of the wall pushing back on the student? What is the acceleration of the student as she moves away from the wall?
Answer:
F=-100N; a=1.3m/s^2
Explanation:
Force is being made by student, so wall counteracts that force by not moving so it is equally opposite.
The force of the wall pushing back on the student would be 100 Newtons, and the acceleration of the student as she moves away from the wall would be 1.33 m/s²
