Answer:
<h3>14.97m/s</h3>
Explanation:
Given
Initial velocity of the car u = 8m/s
Distance travelled by the rider S = 40m
Acceleration a = 2m/s²
Required
rider's velocity after the acceleration v
Using the equation of motion
v² = u²+2as
v² = 8²+2(2)(40)
v² = 64+160
v² = 224
v = √224
v = 14.97m/s
Hence the rider's velocity after the acceleration is 14.97m/s
Gravity and air resistance
i took the test and got 100%
They will rise to the 2nd layer of the atmosphere where the temperature decreases by a lot and then they will blow up
The ampere (A) is a basic SI unit consisting of the amount of electric charge or number of electrons that pass a point in a electrical circuit in one second. The volt (V) is the electrical potential causing electrons to move through a wire. It is a joule of energy per coulomb of charge.
Answer:
Elements are made up of only one type of atom. Each element has a unique chemical symbol. Elements can be identified by their atomic number.
