describe the role of plate tectonics in earthquakes
Answer:
Tectonic plates are constantly moving slowly, sometimes friction between them to lock together and become unable to move.
Explanation:
What net force acting on a 14 KG wagon produces an acceleration of 1.5 MS^2?
Answer:
The wagon exerts a force of 21 Newtons
Explanation:
Force is equal to mass times acceleration, a Newton being 1 kg×m/². As we're given both the mass and the acceleration, all we need to do is multiply them to find the force applied:
14 kg × 1.5m/s²
= 14 × 1.5 kg × m/s²
= 21 N

1. Why is it important for us to know about the changing weather conditions?
2. What kinds of weather can we expect when a cold front is approaching?
Answer:
It's important that we understand how the climate is changing, so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperaturesAs the cold front passes, winds become gusty. There is a sudden drop in temperature, and also heavy rain, sometimes with hail, thunder, and lightning.1.It's important that we understand how the climate is changing, so that we can prepare for the future.

Describe why the shape of the moon appears to change over time.
A)The moon is changing shape as it orbits around Earth and the sun.
B)The moon creates more light as it changes its position around Earth.
C)The sun orbits Earth, giving off different amounts of light to the moon.
D)The sun is lighting up different parts of the moon during the moon's orbit around Earth.
Answer:
think its A hope im right
Properties of Light please help me
Answer:
The primary properties of visible light are intensity, propagation-direction, frequency or wavelength spectrum and polarization, while its speed in a vacuum, 299 792 458 m/s, is one of the fundamental constants of nature.
The diagram below shows a model of the Earth's orbit around the Sun.

I and III
II and III
IV and II
I and IV
Answer:
the answer is I and IV hope it's right
Explanation:
How high does Pete lift his sledge hammer if he used a force of 25N to lift the hammer while doing 50J of work?
Answer:He lifts 2 meters
Explanation:We are trying to find the distance. The formula for distance is W/Force. 50 is our amount of work. 25N is how much force was used. Divide the work bye the force. 50/25=2M
