A car starts at rest and accelerates at a rate of 4 m/s^2. How far does the car travel in 5
1 answer:
Answer:
C. 50m
Explanation:
Given parameters:
Initial velocity = 0m/s
Acceleration = 4m/s²
Time of travel = 5s
Unknown:
distance covered = ?
Solution:
To solve this problem, we use the expression below;
S = ut + at²
S is the distance
u is the initial speed
t is the time
a is the acceleration
S = (0x 5) + x 4 x 5² = 50m

True since coulomb's law states that There is electric force between like charges or opposite charges. The negative sign only shows the nature of the force.
<h3>What is the coulombs law ?</h3>
coulombs formula is given by
Now it states that if two charged particles are separated by the distance r and having same or opposite charge will attract or repel each other.
The intensity of the force depend upon the distance and the nature of the charge.
