It's important because you have to know when to make it go faster or else you might not be able to go upside down or in a circle

Knowing how fast a roller coaster travels at certain points on a track is usually used to calculate how much kinetic and potential energy the object has at that position. This is because total energy is the sum of kinetic and potential energy. Since kinetic energy is associated with velocity then knowing it as certain points on the track will help you calculate how much kinetic energy the object has.

It is found that the most probable speed of molecules in a gas at equilibrium temperature
kaheart [24]

Answer:

\frac{T_2}{T_1} = 1

Explanation:

The root mean square velocity of the gas at an equilibrium temperature is given by the following formula:

v = \sqrt{\frac{3RT}{M} }

where,

v = root mean square velocity of molecules:

R = Universal Gas Constant

T = Equilibrium Temperature

M = Molecular Mass of the Gas

Therefore,

For T = T₁ :

v = \sqrt{\frac{3RT_1}{M} }

For T = T₂ :

v = \sqrt{\frac{3RT_2}{M} }

Since both speeds are given to be equal. Therefore, comparing both equations, we get:

\sqrt{\frac{3RT_1}{M} }=\sqrt{\frac{3RT_2}{M} }\\\\\frac{T_2}{T_1} = 1

A ball is dropped from some height. It bounces off the floor and rebounds with a speed that is one-half the speed it had just be
Arada [10]

Answer:

The correct option is C

Explanation:

According to third equation of motion, v

2

=u

2

+2ax

Here, u=0 m/s

a=−g and x=−h

Negative sign indicates downward direction. Displacement and acceleration both are downwards.

So,v=±

2(−g)(−h)

​

We take minus sign because it is downwards.

v=−

2gh

​

After bouncing. velocity becomes 80% of v, i.e.,

v

′

=+0.8

2gh

​

 

(positive sign because the direction of ball has reversed after bouncing and is upwards.

Applying third equation of motion again, for u=v

′

, v=0 and a=−g

v

2

=u

2

+2×a×x

Thus,

0=0.64(2gh)+2(−g)x

or

x=0.64h

Fuse should not be connected with neutral wire.Why? Write any two electric devices.​
Colt1911 [192]

Answer: Because the fuse can disconnect the circuit only when the excess current flows completely through the neutral. ... Since, neutral is not a live conductor coming from the source, disconnecting a neutral line can only open the current path through neutral. But, the live phase still carries the charge.
