Forces Quiz 1. What is true about all forces?
a. They are unbalanced
b. They involve more than one object
c. They cause objects to move
d. They cancel each other out

Answers

Answer 1
Answer: B they involve more than one object
Answer 2
Answer:

Final answer:

The accurate answer to the question on forces is that they involve the interaction between at least two objects. This is basic to Newton's Third Law of Physics stating that for every action, there is an equal and opposite reaction. Correct option is b.

Explanation:

The correct answer to this forces quiz question is b. They involve more than one object. Physics, specifically Newton's Third Law, states that for every action, there is an equal and opposite reaction. This law implies that a force involves the interaction between at least two objects. The other potential answers are incorrect as forces can be balanced or unbalanced, they may or may not cause objects to move, and they only cancel each other   out when they are equal in magnitude but opposite in direction.

Evaporation: Large amounts of water evaporates from the Earth's ________, _______, __________ every day. The water vapor (evaporation) becomes part of the ________.

Answers

my guesses would be 

surface,oceans,rivers,atmosphere

Possible answers:

oceans/seas/lakes/rivers

atmosphere/sky

Explanation:

Most of the air's moisture evaporates from rivers, lakes, seas, and oceans. Water at the surface of the Earth evaporates into water vapor, which rises into the sky and forms clouds, which eventually release water back onto Earth as precipitation.

True or false: The jet stream carries cold air to the tropics and warm air to the poles

Answers

False. The jet stream does not carry cold air to the tropics and warm air to the poles.

What is the jet stream at high altitude?

The jet stream is a high-altitude, fast-moving air current in the atmosphere that generally flows from west to east. It is caused by the temperature differences between the polar regions and the mid-latitudes.

In reality, the jet stream tends to separate cold polar air from warmer air in the mid-latitudes. It meanders and can have a significant impact on weather patterns, but its primary function is not to transport warm or cold air to the poles or tropics. Instead, it plays a crucial role in the development and movement of weather systems, affecting things like storm tracks and weather conditions in different regions.

Final answer:

The jet stream does not carry cold air to the tropics or warm air to the poles.

Explanation:

The statement 'The jet stream carries cold air to the tropics and warm air to the poles' is false. The jet stream is a narrow band of strong wind in the upper atmosphere that flows from west to east. It generally moves air masses from west to east across the globe, but it does not carry cold air to the tropics or warm air to the poles. Instead, it helps distribute weather systems and influences the movement of storms.

You adjust the temperature so that a sound wave travels more quickly through the air. You increase the temperature from 30 degrees c to 36 degrees c. what is the velocity if the sound wave at this new temperature?

Answers

To calculate the velocity of the sound wave, we use this formula:
V = 331 + [0.6*T], 
Where V is the velocity and T represents temperature.
When the temperature is 36 degree Celsius, we have 
V = 331 + [0.6 * 36]
V = 331 + 21.6 = 352.6 
Therefore, V = 352.6 m/s.

352.6 m/s just took the test

How does an electric motor work

Answers

AC motors work a slightly different way: they pass alternating current through opposing pairs of magnets to create a rotating magnetic field, which "induces" (creates) a magnetic field in the motor's rotor, causing it to spin around. You can read more about this in our article on AC induction motors.
