Does mass or height have a greater impact on gravitational potential energy ?
natulia [17]

The formula for gravitational potential energy is ...

Grav PE = (mass) · (gravity) · (height)

We can see from this simple formula that mass and height have <em>EQUAL </em>influence on the Gravitational PE.  If EITHER of them is multiplied by some factor, the Gravitational PE gets multiplied by the same factor.

So the answer to the question is: <em> No </em>.

Calculate the period of a ball tied to a string of length 0.468 m making 3.8 revolutions every second. Answer in units of s. You
Bogdan [553]

Answer:

0.26315 s

Explanation:

The frequency of the ball tied to a string system is 3.8 rev/s.

That means in one second the ball will complete 3.8 revolutions.

The time period will be the reciprocal of this frequency

T=\dfrac{1}{f}\\\Rightarrow T=\dfrac{1}{3.8}\\\Rightarrow T=0.26315\ s

The time period is 0.26315 s

It can be also solved in the following way

1\ s=3.8\ rev\\\Rightarrow 1\ rev=\dfrac{1}{3.8}\ s\\\Rightarrow 1\ rev=0.26315\ s

The time period is 0.26315 s
