Which mathematical relationship best describes a graph of gravitational field strength versus distance? (one of the 3 pictures attached or none of the above?)

Answers

The gravitational force between two masses is proportional to

(mass-1) x (mass-2) / (the distance between them)-squared

Do you see (distance-squared) in the denominator there ?

FALSE. The energy transformation is from gravitational potential energy (due to height) to kinetic energy (due to speed).

The centripetal force acting on a satellite in orbit A. acts as an unbalanced force on the satellite.
B. changes the direction of the satellite.
C. is a center-directed force.
D. all of the above

Answers

The centripetal force (of gravity) on a satellite in orbit is an
unbalanced force (because there's no equal force pulling
the satellite away from Earth), changes the direction of the
satellite (into a closed orbit instead of a straight line), and
always acts toward the center of whatever curve the satellite
happens to be on at the moment.

Answer : (D) " all of the above "

Explanation :

The forces acting on a satellite are Earth's gravitational force and centripetal force. The properties of centripetal force acting on a satellite in orbit are as follows :

(1) It acts as an unbalanced force on the satellite. This is due to the reason that there is no same force present which pulls the satellite away from the earth.

(2) It changes the direction of the satellite. The satellite is revolving with a constant speed while the direction is kept on changing (in a circular motion).

(3) Centripetal force always acts towards the center.

So, the correct option is (D) " all of the above "

A 1200 kg automobile is traveling at a velocity of 100 m/s is its energy potential or kinetic? How much energy does it possess?

Answers

The energy possess is 6,000,000 J

The kinetic energy is a energy by which an object can move and potential energy is a stored energy which depends upon the relative position of various parts of the body.

Given:

The mass of automobile is $m=1200\:\rm kg$ .

The velocity of the automobile is $100\;\rm m/s$ .

How to calculate potential energy and kinetic energy?

Write the formula to calculate the potential energy of the body.

$P.E=mgh$

Since the automobile is on ground so the height $h$ will be 0.

$P.E=1200* 9.81* 0\nP.E=0$

Write the formula to calculate the kinetic energy.

$K.E=(1)/(2)mv^2$

Substitute the value.

$K.E=(1)/(2)* 1200* 100^2\nK.E= 6,000,000 J.$

Answer:

6,000,000 J (6 million)

Explanation:

Refer to the equations for potential and kinetic energy.

$KE = (1)/(2)mv^(2)\nPE = mgh$

Because the automobile is on the ground (it does not give a height above the ground, therefore we can assume that it is on the ground), height = 0. If you plug in 0 for h in the potential energy equation, we get PE = 0 J.

Therefore, all of the energy is kinetic. Plug in the given information into the kinetic energy equation. M = 1200 kg and v = 100 m/s

$KE = (1)/(2)mv^(2) = (1)/(2)(1200)(100^(2)) = 6,000,000\ J$
