Answer:
M. Magnetism is a property of individual atoms.
Explanation:
when a magnet is broken into pieces the new pieces behave like the original magnet this observation shows that magnetism is the property of individual atoms.

Answer:
The speed of electron is and the speed of proton is 2468.02 m/s.
Explanation:
Given that,
Electric field, E = 560 N/C
To find,
The speed of each particle (electrons and proton) 46.0 ns after being released.
Solution,
For electron,
The electric force is given by :
Let v is the speed of electron. It can be calculated using first equation of motion as :
u = 0 (at rest)
For proton,
The electric force is given by :
Let v is the speed of electron. It can be calculated using first equation of motion as :
u = 0 (at rest)
So, the speed of electron is and the speed of proton is 2468.02 m/s. Therefore, this is the required solution.
Answer: 33.3 m/s^2
Explanation:
Here we need to use the second Newton's law.
F = m*a
Force equals mass times the acceleration.
Here we know that the force is F = 4000 N, and the mass is 120kg, then the acceleration must be:
4000 N = 120kg* a
a = (4000/120) m/s^2 = 33.3 m/s^2
Power = change in work/change in time
P = 600 joules/ 4 seconds
P= 150 watts
hope this helps :)
