KE = 8887.5 J
<h3>Further explanation</h3>
Given
speed = 15 m/s
weight = 79 kg
Required
KE-Kinetic energy
Solution
Energy is the ability to do work
Energy because its motion is expressed as Kinetic energy (KE) which can be formulated as:
Input the value :
KE = 1/2 x 79 kg x 15² m/s²
KE = 8887.5 J

I think its b lol correct me if I'm wrong
Answer:
6.78 X 10³ N/C
Explanation:
Electric field near a charged infinite plate
= surface charge density / 2ε₀
Field will be perpendicular to the surface of the plate for both the charge density and direction of field will be same so they will add up.
Field due to charge density of +95.0 nC/m2
E₁ = 95 x 10⁻⁹ / 2 ε₀
Field due to charge density of -25.0 nC/m2
E₂ = 25 x 10⁻⁹ / 2ε₀
Total field
E = E₁ + E₂
= 95 x 10⁻⁹ / 2 ε₀ + 25 x 10⁻⁹ / 2ε₀
= 6.78 X 10³ N/C
Answer:
They respond to the weak force but not to the electromagnetic force, which means they cannot emit light.
Explanation:
Answer:
A. 200 J
Explanation:
The initial kinetic energy depends on the initial speed, while the gravitational potential energy depends on the height, both balls are thrown with the same initial speed and from the same height. Therefore, due to the law of conservation of energy, the balls must have the same mechanical energy (the sum of both energies) when both impact the ground. Since the potential energy is zero at this point, its final kinetic energy must also be the same.
