dlinn [17]4 years ago
5 0

No, that statement is false.

In uniform circular motion, the direction is constantly changing, but the speed is constant.

How much does mass slow down time?
nalin [4]

Answer:

 In physics, if there is biggest mass then the slow down time is more and this effect is basically known as gravitation time dilation. This type of effect can easily be calculated from the different type of metric in the environment.

When some outsider observe then, this effect time seemed to be slowed down. It basically measure the overall amount of the time which elapse at observer distance. Therefore, this is the main concept of the mass slow down time.

A vertically polarized light wave of intensity 1000 mW/m2 is coming toward you, out of the screen. After passing through this po
Bingel [31]

Answer:

The intensity is I  =  500 mW/m^2

Explanation:

From the question we are told that

    The  intensity of the unpolarized light is I_o  =  1000 \ m W  /m^2  =  1000 *10^{-3} \ W/m^2

Generally the intensity of the light emerging from the polarizer is  mathematically represented as

          I  =  \frac{I_o}{2}

substituting values

         I  =  \frac{1000 *10^{-3}}{2}

         I  = 500 *10^{-3} W/m^2

         I  =  500 mW/m^2

A boy throws a water balloon at his friend. If the work done on the balloon is 20j and it has a mass of 1kg what is the speed of
inessss [21]

Answer:

The speed of of the balloon is about 6.32 m/s

Explanation:

Assuming all of the work done is transformed into the balloon's kinetic energy, we can use the formula for the kinetic energy to answer the question:

E_k=\frac{1}{2}mv^2\\20J = \frac{1}{2}1kg\cdot v^2\implies v=\pm\sqrt{40\frac{m^2}{s^2}}\approx\pm6.32\frac{m}{s}

Speed is the absolute value of velocity, so the speed of the balloon is about 6.32 m/s
