Answer:
≈ 22¢
Explanation:
240 / 1000 = 0.240 kV
0.240 kV(2.5 A)(3 hr) = 1.8 kW•hr
1.8 kW•hr($0.12/kW•hr) = $0.216
Answer:
Not possible
Explanation:
Unless there's some extra external force to keep both particles at rest after the collision, the momentum must be conserved before and after the collision.
So before the collision, 1 particle is at rest, 1 not -> total momentum is non-zero
After the collision, both particles are at rest -> total momentum is zero which is different from before.
Therefore this is not possible.
Answer:
Explanation:
Given
Mass of block A
=2.6 kg
Mass of block B
=0.81 kg
Force of 6.5 N is applied on Block A
Force on Block A is F, Tension
thus
-----1
where a=acceleration of the system
For Block B
-----2
