Explanation:
U = 40m/s
V = 30m/s
T = 5 sec
A = ?
since it's decreasing in speed, The acceleration will be " - 2.0ms^-2 " or " - 2.0m/s^2 "

Btw don't mind me answering twice. I want the free points and maybe another brainliest? lol.
Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
Good experimental design includes a hypothesis that is <span>testable and observable.</span>
The magnetic field B generated by wire 1 at distance r (where wire 2 is located) is
where I1 is the current in wire 1. So, the force exerted on a segment
of wire 2 is
By susbstituting B inside the expression of F, we find the formula for the force per unit of length between the two wires:
where r is the distance between the two wires.
By susbstituting the numbers of the problem, we get
Answer:
Explanation:
Given that
We know that
By using energy conservation
Heat lost by water = Heat gain by block
Therefore the specific heat of the block will be 0.501 kJ/kg.K
Answer:
Particles of the medium are displaced completely from their initial positions, moving along with the wave front
