Yes, this is true. Van de Graaff generators are devices that produce static this electricity right now.

Yes, that is true. Van de Graaff generators are devices that produce static electricity. Static does not involve acceleration, meaning it is motionless which applies to the building of electric charges since the building up of these electric charges are created in a way to not move. Therefore, the sentence you have stated is an accurate statement. 

Let me know if you need anything else. :)

Olenka [21]

Answer:

c.

Explanation:

  • In absence of friction, total mechanical energy must be conserved.
  • This means that the change in gravitational potential energy (in magnitude) must be equal to the change in kinetic energy:

       \Delta K = \Delta U \\ \\  \frac{1}{2} * m* v^{2}  = m*g*h

  • As it can be seen, the mass m is on the both sides of the equation, which means that it can be simplified.
  • We can solve this equation for v (speed at the bottom) as follows:

        v = \sqrt{2*g*h}

  • As it can be seen, the mass has no part in the equation, so, due both are starting from the same height, both people have the same speed at the bottom.
  • The option c is the right one.

What is the direction of a vector with an x component of -12 m and a y component of -15 m?
dusya [7]

Answer:

51.34^{\circ}

Explanation:

Given that,

x component of a vector = -12 m

The y component of a vector = -15 m

We need to find the direction of a vector. The direction of a vector is given by :

\tan\theta=\dfrac{y}{x}

Put all the values,

\tan\theta=\dfrac{-15}{-12}\\\\\theta=\tan^{-1}(\dfrac{-15}{-12})\\\\\theta=51.34^{\circ}

So, the direction of vector is 51.34^{\circ} to x component.
