Answer:
Explanation:
Given,
For the first rocket,
- Initial velocity of the first rocket A =
- Acceleration of the first rocket =
For the second rocket,
- Initial velocity of the second rocket B =
- Displacement of both the rockets A and B = s = 0 m
Fro the first rocket,
Let 't' be the time taken by the first rocket A for whole the displacement
Let 
be the acceleration of the second rocket B for the same time interval
from the kinematics,
Hence the acceleration of the second rocket B is -33.65\ m/s^2.
Answer:50 N
Explanation:
Given
Initially scale reads 40 N
a block of wood with weight 10 N is placed in beaker
Now the scale will read 50 N as it has bear the weight of both water and wood because no water is spilled out of beaker and wood is also present .
Total reading on scale =40+10 =50 N
Although effective weight of wood be less as buoyancy is acting on it.
Answer:
Vega: It is fusing hydrogen at its core.
Procyon B: It has lost its outer shell and retained only a hot core that is slowly losing its brightness.
Polaris: Its temperature has decreased, but it is shining brighter than before.

Answer:
The inertia of an object is a measure of its resistance to a change in the state of its motion. It is solely dependent on the mass of the object, with more massive objects having larger inertia and a greater tendency to resist changes to their motion.
Explanation:
As the distance increases, their magnetic force decreases....
