What is the acceleration of gravity if you are on planet earth? *

Given :

An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west.

It starts at the 14-inch mark, crawls to the 20-inch mark, then moves to the 16-inch mark.

To Find :

The total distance the ant traveled.

Solution :

Total distance travelled by ant = (distance between 14 and 20 inch mark) +

                                                      (distance between 20 and 16 inch mark)

Total distance = (20-14 ) + ( 20-16) = 6 + 4 = 10 inch.

Therefore, total distance the ant traveled is 10 inch.

Hence, this is the required solution.

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

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.

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.

Hope this helps :) :) :)

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.

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

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

Newton's third law of motion state that for every action force there exists a complementary reaction force that balances it.

As given in the problem 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,

The force of the wall pushing back the student = 100 Newtons

The acceleration of the student = 100/75

                                                     =1.33 m/s²

Thus, The student would be pushed back against the wall by a force of 100 Newtons, and she would accelerate away from the wall at a rate of 1.33 m/s².

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

The second image showing an electromagnet is an example of the electromagnetic force in action therefore the correct option is B

It is a type of force that occur between electrically charged particles. The electromagnetic force is the combination of all the electrical and magnetic forces generated from any charged particle,

These electromagnetic forces either be attractive or repulsive.

The force generated from a simple bar magnet is an example of the electromagnative force, hence the correct option is B

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.

Answer:

Which has more inertia - a car with a mass of 900kg or a car with a mass of 1500kg - explain. The bigger the mass - the larger the inertia but you need to exert more force to start the movement.

Explanation:

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.

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.

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.

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.

Explanation:

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
