Velocity B (relative to the A) = Velocity B (relative to the ground) - Velocity A (relative to the ground)
Velocity B (relative to the ground) = Velocity B (relative to the A) + Velocity A (relative to the ground)
Velocity B (relative to the ground) = 7.5 + 5 = 12 m/s
Since both go up in the same direction, we should use the minus sign for relative velocity.
Well if Block A is on top of Block B, then the total mass is the sum of Block A and Block B. Therefore the total mass is 16kg. Since the blocks are not moving, the force of gravity is equal to the normal force.
Answer:
The velocity of a ball will be "-70.13 m/s".
Explanation:
The given values are:
u = 70 m
t = 0.0 s
g = a = -9.8 m/s²
s = -1 m
v = ?
As we know,
The equation of motion will be:
⇒
On substituting the estimated values, we get
⇒
⇒
⇒

In downward direction, it will be:
⇒
There is still enough hydrogen to fuse into more Helium but the core begins fusing into larger atoms, as soon as the Helium in the core runs out the star collapses again, heats up, and starts fusing carbon and oxygen into larger atoms
Answer:
-11776.36 N
This force is attractive since both charges are of opposite sign
Explanation:
Given that
Distance between the spheres = 2.73 cm =0.0273 m
where K is Coulomb's constant =
According to coulombs law we know that force between two charges is given by
This force is attractive since both charges are of opposite sign
