Yanka [14]3 years ago
4 0

Answer:

At 400 m the potential energy of the mountain climber doubled the initial value.

Explanation:

Given;

initial height of the mountain climber = 200 m

final height of the mountain climber, = 400 m

The potential energy of the mountain climber is calculated as;

Potential energy, P.E = mgh

At 200 m, P.E₁ = mg x 200 = 200mg

At 400 m, P.E₂ = mg x 400 = 400mg

Then, at 400 m, P.E₂ = 2 x 200mg = 2 x P.E₁

Therefore, at 400 m the potential energy of the mountain climber doubled the initial value.

SHOULD YOU TRY TO KEEP A "SPACE CUSHION" AROUND YOUR VEHICLE WHENEVER POSSIBLE? A. Yes, when another driver makes a mistake, you
Veronika [31]

Answer:

A. Yes, when another driver makes a mistake, you will have time to react

Explanation:

Yes it is good to make space cushion between two cars because due to some urgency when front vehicle applied brakes then the driver of the rear car will definitely take some time to react.

This reaction time may be between 0.5 s to 0.8 s for different people

so the rear car will move with same speed for above reaction time and it will cover the cushion distance between two cars

If we will not maintain this cushion distance between two cars then we can see that the two cars will collide and that may cause many accidents

so it is correct statement and correct option would be

A. Yes, when another driver makes a mistake, you will have time to react

A student uses the right-hand rule as shown. an illustration with a right hand with fingers curled and thumb pointed up. what is
Afina-wow [57]

The direction of the magnetic field in front of the wire closest to the student is on the left. The direction is found by the right-hand rule.

<h3>What is the right-hand rule?</h3>

The right-hand rule is a popular mnemonic for remembering how axes in three-dimensional space are oriented.

The fact that the three axes of three-dimensional space have two different orientations gives birth to the majority of the many left-hand and right-hand rules.

Using the right-hand rule, we can recall this diagram. Your thumb points in the direction of the magnetic force pushing on the moving charge

If you point your pointer finger in the direction of the positive charge and then your middle finger in the direction of the magnetic field.

To learn more about the right-hand rule refer to the link;
