Example Item Description of potential-kinetic energy conversion

Example Book The book had potential energy when it was on the table. Then as the book fell off the table, it was in motion and had kinetic energy.

1 ball The ball had potential energy because it was in one place. Then it rolled off the counter and it was kinetic energy.

2 Paper airplane The airplane was sitting on the table in had potential energy until I picked it up and threw it which made it kinetic energy.

3 Chips Chips were in the closet sitting on the shelf which is potential energy and one fell of the shelf which made it kinetic energy.

4 Clock I put my clock on the wall which is potential energy and then a few days later it fell off which is kinetic energy.

5 water I had water sitting in a cup which is potential energy the I grabbed it and spilled which makes the water kinetic energy.

The moon clock is A) (9.8/1.6)h compared to 1 hour on Earth

Explanation:

The period of a simple pendulum is given by the equation

$T=2\pi \sqrt{\frac{L}{g}}$

where

L is the length of the pendulum

g is the acceleration of gravity

In this problem, we want to compare the period of the pendulum on Earth with its period on the Moon. The period of the pendulum on Earth is

$T_e=2\pi \sqrt{\frac{L}{g_e}}$

where

$g_e = 9.8 m/s^2$ is the acceleration of gravity on Earth

The period of the pendulum on the Moon is

$T_m=2\pi \sqrt{\frac{L}{g_m}}$

where

$g_m = 1.6 m/s^2$ is the acceleration of gravity on the Moon

Calculating the ratio of the period on the Moon to the period on the Earth, we find

$\frac{T_m}{T_e}=\frac{g_e}{g_m}=\frac{9.8}{1.6}$

Therefore, for every hour interval on Earth, the Moon clock will display a time of

A) (9.8/1.6)h

¿Qué resistencia debe ser conectada en paralelo con una de 20 Ω para hacer una

ValentinkaMS [17]

Answer:

60 Ω

Explanation:

R(com) = 15 Ω

1/R(com) = 1/R1 + 1/R2 + 1/R3 ..... + 1/Rn

1/15 = 1/20 + 1/R2

1/R2 = 1/15 - 1/20

1/R2 = (4 - 3) / 60

1/R2 = 1/60

R2 = 60 Ω

así, la combinada de resistencia necesaria es 60 Ω
