Answer:
(a)
(b)
(c)
Explanation:
(a) The total mechanical energy of the system is conserved.
(b) The conservation of energy states
(c) As explained in part (a) the total mechanical energy of the system is equal to the initial kinetic energy, since the potential energy of the system at that point is zero.
What is the magnetosphere, and how does it help the earth?
The magnetosphere shields our home planet from solar and cosmic particle radiation, as well as erosion of the atmosphere by the solar wind - the constant flow of charged particles streaming off the sun. ... It is generated by the convective motion of charged, molten iron, far below the surface in Earth's outer core.

Answer:
A tuner is a subsystem that receives radio frequency (RF) transmissions and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output.

Answer:
Required time t=5.8s
Explanation:
Given data
Acceleration a=3.08 m/s²
Speed v=29.4 m/s
Required
How much time t is required
Solution
As the train passes through the crossing its motion is described by:
Substitute the given values
So
So time required can be calculated by:
Required time t=5.8s
