The time needed by the bike to reach the final velocity is 3 .75 seconds ,Option C is the write answer.
<h3>What is Velocity ?</h3>
It is defined as the distance covered by an object in a given amount of time. It is a vector quantity , its unit is m/s , km/hr etc.
It is given in the question that
Initial Velocity = 20m/s
Final Velocity = 35m/s
Acceleration = 4m/sq.s
Time = ?
The equation of motion
v = u +at will be used
35 = 20 + 4 * t
15 = 4* t
t = 3.75 seconds
Therefore the time needed by the bike to reach the final velocity is 3 .75 seconds.

The answer is 1.98 x 10^10 leaves.
18 mountains x 8800 trees = 158400 total trees
158400 total trees x 125000 leaves = 19800000000 total leaves in entire mountain range
Sci not: 1.98 x 10^10 leaves
To do scientific notation, put the decimal place right after the first digit in the number and count how many places are behind the decimal. you'll write the number of places after the decimal after the ^ in the 10^.
Light does not travel at a constant speed in a vacuum, compared to in air, because the light is being absorbed by atoms and molecules in the air. But light does travel at a constant speed in a vacuum.
So I agree with A
All that talk about moving forward is irrelevant (I think)
Answer:
Ali will need to either taste test or test the drinks on a ph scale. A neutral drink is water, as neutral has a ph of 7. The ph scale ranges from 1 to 14, going from acidic to basic. So if the drink has a ph less than 7, it is acidic, if its more, its basic.
answer is A
The kinetic theory is used to explain the behaviour of gases.
One of the assumptions states that "a gas is composed of a large number of identical molecules moving at different speeds".
