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?

Answers

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.

What net force acting on a 14 KG wagon produces an acceleration of 1.5 MS^2?

Answers

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

describe the role of plate tectonics in earthquakes

Answers

Answer:

Tectonic plates are constantly moving slowly, sometimes friction between them to lock together and become unable to move.

Explanation:

Tectonic plates move at about the same speed as your fingernails grow. When the earthquake happens, one plate goes in a rough upward position while the other goes under the up facing plate. Earthquakes don’t only happen like that. They can happen also when they collide in with each-other, almost touching tips with each-other. Images will be provided to show both ways. Here:
