An object's gravitational potential energy is NOT directly related to which of the following?

2 answers:

8 0

The correct answer is C. Its speed

Speed is related to the kinetic energy, not the potential one because kinetic requires the body to be in motion, that is, move at a certain speed. Potential energy has no motion.

Explanation :

The mechanical energy is the sum of the potential energy and the kinetic energy i.e.

ME = PE + KE

Kinetic energy is due to the motion of an object.

Potential energy is possessed by an object due to its height under the action of gravity.

Mathematically, it is written as :

PE =mgh

Where

m is the mass of the object

g is acceleration due to gravity

h is the height relative to reference level.

So, an object's gravitational potential energy is NOT related to its speed.

Hence, the correct option is (c) 'Its speed'.

Distance between Ranjan and Gomes house is 9km. Ranjan has to attend Gomes birthday party at 7 o'clock. He started from his home

Nataliya [291]

Answer:

Kindly check explanation

Explanation:

Given the following :

Distance between Ranjan and Gomez house = 9km

Start time = 6'o clock

Time he arrived at Gomes house = 7'o clock

Time used for chatting during this period = 5 minutes

Distance covered in 40minutes = 6km

Time spend for second part of the journey = (60 - (40 + 5))minutes = 15 minutes = 15/60 = 0.25 hoir

Distance covered during second part of journey = 9 - 6 = 3 km

Speed = distance / time

Speed = 3km / 0.25 hr = 12km/hr

Average speed for entire journey :

First part :

Speed = distance / time

Time = 40 minutes = (40/60) = 0.667 hour

Speed = 6km / 0.667 hour = 9km / hr

Average speed :

(First part + second part) / 2

(9km/hr + 12km/hr) / 2 = 21km/hr / 2 = 10.5 km/hr

= 10.5km/hr

Students were discussing a problem in which the class was asked to find the acceleration of a cart rolling up and down an inclin

velikii [3]

Sasha is correct: No, the velocity is changing at the top so the acceleration cant be zero.

Explanation:

The acceleration of an object is equal to the rate of change in velocity of the object:

$a=\frac{\Delta v}{\Delta t}$ (1)

where

$\Delta v$ is the change in velocity

$\Delta t$ is the time interval

For the cart on the ramp, as the cart reaches the top of the ramp, its velocity becomes temporarily zero:

v = 0

This is the origin of Malia's mistake.

However, this only lasts a moment; in reality, its velocity is changing, in particular its direction is changing (from upward to downward).

As we can see from eq.(1), a non-zero change in velocity implies a non-zero acceleration. Therefore, Sasha is right, since the cart has a non-zero acceleration.
