Answer:
D
Explanation:
A catalyst speeds up a chemical reaction, without being consumed by the reaction. It increases the reaction rate by lowering the activation energy for a reaction.
Answer: a
Explanation: It is the only answer that is precipitation
Answer:
Explanation:
According to Newton's second law, we have:
The force of friction is opposite to the motion of the block.
Using the following kinematic equation, we can calculate the distance traveled by the block before it stops().
Solving for x and replacing a from (1):
Answer:
The temperature would get warmer.
Explanation:
It indicates heat from earth’s warm interior surface. The temperature increases for about 25℃ for every single kilometer of depth.
Okay so static friction is when the atoms lock themselves into place, which makes it 'hard' to push until you exceed its static force.
You can calculate the Fs by finding your normal force and multiplying it by your static friction force.
N = mg = (9.8)(42) = 411.6 N
Fs = NKs = (411.6)(0.75) = 308.7
a) the maximum force of static friction between her socks and the floor is 308.7 N
b) If you push Mazie with a force of 350 she will slide. She will accelerate if you keep pushing her with the constant force, but if you push her and let go the kinetic friction will eventually bring her to a stop.
c) So this is an interesting question, she's going at a speed of 0.6 m/s. Kinetic friction is pushing her back so theres a negative force which is the force of kinetic friction right. So its NKf = (411.6)(0.62) = 255.192.
