Answer:
Acceleration
Explanation:
The advertisement is describing the acceleration of the car.
Acceleration is the rate of change of velocity per unit of time. It can be expressed mathematically as;
Acceleration =
v is the final velocity
u is the initial velocity
t is the time taken
Any quantity that specifies the rate of change of velocity of a body within a given time frame is describing its acceleration.
Answer:
V=203 ft/s
Explanation:
answer is available in word document named "attach 1" due to some technical error in maths equation. please find the attached document

The time period of the communications satellites must be 24 hours to make one complete orbit around the earth.
An object that has been placed into orbit in space on purpose is known as a satellite or artificial satellite. Most spacecraft, with the exception of passive satellites, contain a means of generating electricity for the electronics they carry, such as solar cells or radioisotope thermoelectric generators.
A communications satellite is a man-made spacecraft that uses a transponder to relay and amplify radio telecommunication signals. It establishes a channel of communication between a source transmitter and a receiver situated at various points on Earth.
Most satellites that orbit the Earth do so between 160 and 2,000 kilometers above the surface. Because of how closely the satellites are orbiting the Earth, this orbital regime is known as low Earth orbit or LEO. The normal orbital period for satellites in low Earth orbit (LEO) is between 90 and 2 hours.

Answer:
Change in momentum will be -4.4 kgm/sec
So option (A) is correct option
Explanation:
Mass of the ball is given m = 0.10 kg
Initial velocity of ball 
And velocity after rebound 
We have to find the change in momentum
So change in momentum is equal to
( here negative sign shows only direction )
So option (A) will be correct answer
