Anything that has mass has weight and anything that has weight has mass simple.
Answer:
The answer to your question is Ke = 72 J
Explanation:
Kinetic energy depends on the speed of and object and its mass.
Data
mass = m = 4 kg
speed = v = 6 m/s
distance = d = 8 m
Kinetic energy = ke = ?
Formula
Ke = (1/2) mv²
Substitution
Ke = (1/2) (4)(6)²
Simplification
Ke = (1/2)(4)(36)
Ke = (1/2)(144)
Ke = 72 Joules
Result
Ke = 72 J
Answer:
i E=V/d=50/2*10^-3=25*10^3 N/C
ii It is a (+) and (-)
iii C=εA/d
C=12.56*10^-8 * 0.1/2*10^-4
C=62.83 μF
Q=CV=50*6.283*10^-6
Q=314 μC
iv E=0.5 QV
=0.5(50*314*10^-6)
=7850 μJoule
