Answer:
Explanation:
a. WEIGHT: As we have seen, weight is the gravitational force exerted on an object by the Earth (or any other celestial body). If an object is near the Earth's surface and has mass, then the object has a weight. The magnitude of its weight is w = mg and its direction is toward the center of the Earth.
Density = mass /volume= 1000/100= 10 kg/m'3
Answer:
The gravitational potential energy of the skydiver=
Given:
Mass of the skydiver=80kg
Distance of the skydiver from the earth=100m
To find:
Gravitational potential energy of the skydiver
<u>Step by Step Explanation:</u>
Solution:
According to the formula, Gravitational Potential Energy (GHE) is calculated as
Where m= Mass of the skydiver
g=Acceleration due to gravity
h=Distance of the skydiver from the earth
Substitute the known values in the above equation we get
Result:
Thus the gravitational potential energy of the skydiver is =
Answer:
Towards left
Explanation:
Applying Fleming Right hand rule in which the middle finger denotes downward magnetic field. Thumb pointing towards you is the direction of motion of electron beam.The direction of force on the electron indicated by the index finger is towards left. Hence the electron beam is deflected towards left.
