The difference in the speeds of the two balls when they hit the ground is mathematically given as
V=0.10m/s
<h3>What is the difference in the
speeds of the two balls when they hit the ground.?</h3>
Generally, the equation for Acceleration due to electric field is mathematically given as
For Negative charge
In conclusion, the speed of the negative ball
v1=6.21m/s
The difference in v
V=v1-v2
V=6.31-6.21
V=0.10m/s

Answer:
F = 7500 N
Explanation:
given,
mass of the car, m = 1200 Kg
initial speed of the car, v = 25 m/s
final speed of car = 0 m/s
time in which car is at rest, t = 5 s
distance = 50 m
Force = ?
using equation of motion for the calculation of acceleration.
v² = u² + 2 a s
0² = 25² + 2 x a x 50
100 a = -625
a = - 6.25 m/s²
negative sign shows deceleration of the car
now, force calculation
F = m a
F = 1200 x 6.25
F = 7500 N
hence, net force is equal to F = 7500 N
Answer:
The variation and distribution of traits in a population depend on genetic and environmental factors. Genetic variation can result from mutations caused by environmental factors or errors in DNA replication, or from chromosomes swapping sections during meiosis.
