Explanation:
The question says that "Does a 60 kg person running at 4 m/s have more kinetic energy than a 10 gram projectile at 300 m/s ?
"
Speed of a person is 4 m/s
Mass of a person is 60 kg
Kinetic energy of a person is : 
So,
Mass of a projectile is 10 grams or 0.01 kg
Speed of a projectile is 300 m/s
Kinetic energy of a projectile is :
So, it is clear that the kinetic energy of a person is more than that of the kinetic energy of a projectile.
Answer: the water level would rise since the pebble displaces minimal water compared to the boat.

Option C
In nuclear fission and fusion the mass defect is the mass lost during the reaction that is converted into energy
<u>Explanation:</u>
Mass defect is the contrast within the estimated mass of the released system and the empirically estimated mass of the nucleus. The nuclear binding energy is acknowledged as mass, and that mass enhances "missing".
This missing mass is described as a mass defect, which is nuclear energy, also acknowledged as the mass discharged from the reaction as any trajectories. The mass defect of a nucleus depicts the mass of the energy adhesive of the nucleus and is the variation amidst the mass of a nucleus and the entirety of the masses of the nucleons of which it is comprised.
Answer:
The height of the Everest mountain is, x = 8514.087 m
Explanation:
Given data,
The gravitational field strength at the top of mount Everest, gₓ = 9.772 m/s²
The formula for gravitational field strength is,
<em> gₓ = GM/(R+x)²</em>
Where, x is the height from the surface of the Earth
Therefore,
(R+x)² = GM/gₓ
x = √(GM/gₓ) - R
Substituting the values,
x = √(6.67408 x 10⁻¹¹ X 5.972 x 10²⁴ / 9.772) - 6.378 x 10⁶
x = 8514.087 m
Therefore, the height of the Everest mountain is, x = 8514.087 m
