It is shown when you are covering the light.  So like when the sun is shining down at you, you are standing so the stuff behind you is not getting light because you are in its way.

Suppose that video game discs are a normal good. If the income of video game players​ increases, you predict that in the market
DENIUS [597]

Answer:

Both equilibrium price and quantity will increase.

Explanation:

An increase in the income of video game players will surely lead to an upward shift in the supply and demand curve. This shift in the supply and demand curve would affect the equilibrium price and quantity positively leading to a correspondent increase in the equilibrium price and quantity.

A 17 kg box sitting on a shelf has a potential energy of 350 J. How high is the shelf? Round your answer to the nearest whole nu
Free_Kalibri [48]
Potential energy is mass * gravity * height. (m*g*h).

350 = 17*9.8*h   <--350 is its energy, 17kg is its mass, and 9.8 is gravity's acceleration on the object. We now just need to solve for h.

h = 350/(17 * 9.8) =  2.1 meters, which, when rounded to the nearest whole meter, is 2 meters.

The shelf is 2 meters high.

A basketball has a mass of 1 kg and is traveling 12 m/s
cricket20 [7]

A) It would be doubled.

Why?

To answer the question, we just need to calculate the momentum of the basketball using the following formula:

Momentum=mass*velocity\\\\Momenum=1kg*12\frac{m}{s}=12\frac{kg.m}{s}

Now, we have calculated the momentum and the result is 12 kg.m/s, what would happen to the velocity if we double the momentum? Let's calculate it!

Momentum=mass*velocity\\\\(2)*12\frac{kg.m}{s}=1kg*velocity\\\\velocity=\frac{24\frac{kg.m}{s} }{1kg} =24\frac{s}{s}

Hence, we can see that if the momentum is doubled, the velocity will be doubled too.

Have a nice day!
