Answer:
The unit of force is Newton.
Explanation:
Given that,
S.I unit of force = kg -m/s²
Time = second
We need to calculate the unit of force
A constant force exerted on the object, an interval of time during
The force is applied and the resulting momentum of the object P.
Using formula of momentum
....(I)
From equation of motion,
v = a t
From newton's second law
Put the value v and a in the equation (I)
Put the unit of the force and time
Here, 
Hence, The unit of force is Newton.
D, because you are pulling on the rope. :)
Answer:
2dQ²/2εA = 2U₀
Explanation:
The energy stored in the ideal parallel plate capacitor U = Q²/2C. For a parallel plate capacitor, C = εA/d where A is the area between the plates and D is the distance between them. So
U = Q²/2C = Q²/2εA/d = dQ²/2εA. At distance d₁ = d, U = U₀,
U₀ = dQ²/2εA,
When d₂ = 2d, U₁ = d₂Q²/2εA = 2dQ²/2εA = 2U₀
Answer:
the center of mass rises because the whole object rises up on the ramp thing so the center of mass rises
