Answer:
0.495 m/s
Explanation:
= tension force in the string connecting the two objects
= Mass of the object on inclined plane = 250 g = 0.250 kg
= Mass of the hanging object = 150 g = 0.150 kg
= acceleration of each object
From the force diagram, force equation for the motion of the object on the inclined plane is given as

From the force diagram, force equation for the motion of the hanging object on the inclined plane is given as

Using the above two equations



= height dropped by the hanging object = 10 cm = 0.10 m
= Speed gained by the object
Speed gained by the object can be given as

Answer:
d) 12 V
Explanation:
Due to the symmetry of the problem, the potential (relative to infinity) at the midpoint of the square, is the same for all charges, provided they be of the same magnitude and sign, and be located at one of the corners of the square.
We can apply the superposition principle (as the potential is linear with the charge) and calculating the total potential due to the 4 charges, just adding the potential due to any of them:
V = V(Q₁) + V(Q₂) +V(Q₃) + V(Q₄) = 4* 3.0 V = 12. 0 V
Answer:
for example, a person weighing 100kg when on the moon only has 38kg is not wrong because the scale is just a device to measure weight, not mass, people have taken advantage of gravity to measure the weight of objects, so I think Your actual weight doesn't change, what changes is gravity and acceleration
Explanation:
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that the period of revolution of the planet is given by

now we know that

T = 6.3 days

now we have


Part b)
As we know that mass of sun is given as

now we have
