Answer:
91.914138 m
Explanation:
t = Time taken
u = Initial velocity = 15.6 m/s
v = Final velocity = -15.6 m/s (it will hit the ground at this speed)
s = Displacement
g = Acceleration due to gravity = 9.81 m/s² = a
The distance the car will travel is 91.914138 m
Answer:
electric field is 4.75 × V/m
Explanation:
given data
cube of side = 1 mm
energy = 10 J
to find out
magnitude of the electric field
solution
to find electric field
we will apply here energy formula that is
energy = 1/2 × ∈ × E² × volume ...............1
here we know ∈ = 8.85 ×
so put all value to get E electric field
energy = 1/2 × ∈ × E² × volume
10 = 1/2 × 8.85 × × E² × (1/1000)³
solve it and get E
E² = 2× 10 / 8.85 × × (1/1000)³
E = 4.75 ×
so electric field is 4.75 × V/m
