Answer:
No, some energy will be dissipated energy due to work of air resistance.
Answer:
106417026.88435 m
Explanation:
T = Time period of the satellite = 4 days
m = Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
Time period is given by
The radius of the satellite's orbit is 106417026.88435 m
Answer:
speed
Explanation:
The slope of a line on any distance-time graph represents the speed of the object.
Velocity only comes in when there is speed of the object in a particular direction.
The mechanical energy of an object is the sum of its potential and kinetic energy.
Because the ball is on the ground, its potential energy is 0.
Its kinetic energy is given by:
K.E = 1/2 mv²
K.E = 1/2 x 1 x 2²
K.E = 2 J
Mechanical energy = 2 + 0
Mechanical energy = 2 J
The answer is B.
