Answer:
Explanation:
1) J = P = 100 g
Mass does not change with location.
2) 10 m/s
v² = u² + 2as
0² = u² + 2(-10)(5)
3) N(ewton)
Answer:
Electric force on the charge will be equal to -1742000 N
Explanation:
We have given electric field at a point is E = 260000 N/C
And charge q = -6.7 C
We have to find the force on that charge
Force on the charge is equal to Force = charge × electric field ( multiplication of electric field and charge )
So force will be equal to 
So electric force on the charge will be equal to -1742000 N
Answer:
0.031 m
Explanation:
Density of copper = ρ = 8960 kg/m³
r = Radius = 0.262 m
m = Mass of plate = 61.5 kg
v = Volume of plate = Volume of cylinder = πr²h

So, thickness of plate is 0.031 m
