Answer and Explanation:
The inertial reference frame is one with constant velocity or non-accelerated frame of reference.
The value of acceleration and velocity change will vary in the two frames and will not be same.
As in case, we observe the acceleration and velocity of a moving train from the platform and the one observed in the train itself will be different.
In case of energy, it is dependent on the frame of reference but the energy change is independent of the frame of reference.
Answer:
At the same time.
Explanation:
In the first case ,
intial velocity = 0
displacement = -h
acceleration = -g
Using second equation of motion,
s = ut + .5a
- h = - 0.5g
t =
In the second case, consider only motion along y axis,
intial velocity = 0 ( all the velocity is along x axis)
displacement = -h ( height is same in both cases)
acceleration = -g
Using second equation of motion,
s = ut + .5a
- h = - 0.5g
t =
In both cases time is same.
Hence, they will reach the ground simultaneously.

SONAR, satellite radar, GPS, and deep-sea diving vessels all contribute
to accurate MEASUREMENT of the depth and motion of the sea floor, and
of the motion of the continents.
Once the measurements are known, they can be analyzed to determine
whether OR NOT they support the idea of continental drift, or some other
hypothesis.
Real scientists don't go out looking for evidence to support the ideas
that they want supported. That kind of approach to research is found
more in the Flat Earth department.
Answer:
A switch
Explanation:
Without switch the current cannot flow and hence, circuit cannot be activated.
