E=mc² where c is speed of the light
3 m/s more andmore less than speed of the light. So mass of the person still 100 kg
Answer:
12 nC
Explanation:
Capacity of the parallel plate capacitor
C = ε₀ A/d
ε₀ is constant having value of 8.85 x 10⁻¹² , A area of plate , d is distance between plate
Area of plate = π r²
= 3.14 x (0.8x 10⁻²)²
= 2 x 10⁻⁴
C = ( 8.85 X 10⁻¹² x 2 x 10⁻⁴ ) / 2.8 x 10⁻³
= 7.08 x 10⁻¹³
Potential difference between plate = field strength x distance between plate
= 6 x 10⁶ x 2.8 x 10⁻³
= 16.8 x 10³ V
Charge on plate = CV
=7.08 x 10⁻¹³ X 16.8 X 10³
11.9 X 10⁻⁹ C
12 nC .
Answer:
Because it has more mass
Explanation:
To understand this, think about the equation of kinetic energy
KE = 
m 
Kinetic energy depends on both the velocity (v) as well as the mass (m).
Because a lorry is bigger and heavier than a car, it will have more mass. With more mass, at the same velocity the lorry with have more kinetic energy.
Answer:
His third law states that for every action or force in nature there is an equal and opposite reaction.
Explanation:
The heavier the books get, the harder it is for Molly to exert enough force to move the cart.

Answer:
A wave transfers energy as it moves away from the source.
Explanation:
A wave transfers energy as it moves away from the source. A wave is known to be a disturbance that travels through a medium and transfer energy from a point to the other without causing any permanent displacement of the medium itself.
Let's take water as an example of a medium through which wave is transfered. As the water moves away from its source, the wave generates energy. The wave produces a motion which leads to transfer of kinetic energy as the medium moves from its source since kinetic energy is the energy acquired by a body by virtue of its motion.
