The image shows the gravitational effects of the moon (not shown) on the Earth (depicted here) and the resulting tides that form. Which statements are true about the gravitational force between the Earth and the moon? Select ALL that apply.
Responses
A The moon exerts equal gravitational force on all locations of the Earth
B The moon exerts a smaller gravitational force on Earth locations that are farther away
C The moon must be to the right of the Earth because gravity is an attractive force.
D The moon must be to the left of the Earth because gravity is a repulsive force.
E The moon exerts a greater gravitational force on the Earth than the sun does.

Robert is thinking about buying a new refrigerator. His old refrigerator runs at about 43% efficiency. Which most likely accounts for the remaining 57% of the energy?

A: It is used up by the light in the refrigerator.
B: It is released to the surroundings as heat
C: It is converted into mechanical energy.
D: It stored as a form of potential energy.

When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.

In our experiment that will compare how long it will take for 100 ml distilled water to evaporate from a from a 5" diameter container. This will be the control group. For the experiment group, we will use 100 ml of distilled water and dissolve 10 grams of table salt in the water. We will use the same diameter dish for both samples so the same amount of water surface is exposed to the air.
What would a good hypothesis be?
When the salt water was almost evaporated, the higher concentration of salt might have slowed the evaporation process by blocking the air from the moisture.
We think that a pure water sample will dissolve faster than a salt water solution because salt adds more mass to equal quantities of liquids.
It took a total of 31hrs. 15 min. to evaporate the pure water and 32hrs. 10 min for the salt water.
We poured the water into each 5" dish and set the containers on a table. We noted the time: 8:00 a.m. Saturday.

Two cars with identical engines overheated. A mechanic opened the hood of one car and left the hood of the other car closed. This table shows how the temperature of each engine changed over 10 minutes.


Engine Initial temperature (°C) Final temperature (°C)

Engine in the car with the closed hood 105 98

Engine in the car with the open hood 109 95


The next time the mechanic works with an overheated engine, she wants the engine to cool off quickly. What should she do to maximize the rate of thermal energy transfer out of the engine?

Answers:

Leave the hood of the car closed.

Leave the hood of the car open.

Either the rate of thermal energy transfer is the same whether the hood is open or closed.
