Answer is A mark me brainliest
The question has examples of all 3 of Newton's laws of motion.
You just have to know which is which.
Hockey puck . . . First law; law of 'inertia'
Tractor trailer vs sports car . . . Second law; F = M A
Swimmer and raft . . . . . THIS is the third law; action force and REaction force
Car in a fast turn . . . . . First law; another example of inertia
Answer:
30.0625 W
Explanation:
325 g/h x (1h x 1kg)/(3600s x 1000g) x 3,33 x 10^5 J/Kg = 30.0625 J/Kg = 30.0625 W
Answer:
The y-component of the normal force is 45.74 N.
Explanation:
Given that,
Mass of the crate, m = 5 kg
Angle with hill,
We need to find the y component of the normal force. We know that the y component of the normal force is given by :
So, the y-component of the normal force is 45.74 N. Hence, this is the required solution.
Answer:
basically they have too much mass in them
Explanation:
They are held tightly together by strong forces of attraction. They are held in fixed positions but they do vibrate. Because the particles don't move, solids have a definite shape and volume, and can't flow. Because the particles are already packed closely together, solids can't easily be compressed.
