Answer:
Rahul is wrong.
Explanation:
From Newton's universal law of gravitation, we know that the force of attraction between two falling body masses is directly proportional to product of masses of two bodies and has an inverse proportional relation with the square of the distance between the masses.
If the 2 masses are M1 & M2, while distance between them is d, this can be written as;
F ∝ M1•M2
And F ∝ 1/d²
We also know that the acceleration due to gravity is given as;
g = GM/r²
Where;
M is the mass of earth
r is the radius of earth
From the above 3 formulas, we can deduce that the value of the acceleration due to gravity(g) is independent of the 2 masses of the falling body as it depends on only the mass of the earth and radius of the earth.
This means that the acceleration due to gravity will be the same whether the bricks are doubled or whether it remains single.
Thus, they will fall with same velocity in each case. So Rahul is wrong.

Explanation:
Bill is making waves on a rope with one end attached to a wall. When he starts moving the rope quickly, the frequency of the waves created on the rope doubles. What happens to the energy that is transferred to the wall when the frequency of the waves doubles?
a. halved
b. quadrupled
c. doubled
d. tripled
Answer:
The answer is C
Explanation:
The same amount of force is applied to both the wall and the rope
When the frequency of the wave is doubled the energy that is transferred to the wall will be doubled.
What is the frequency?Frequency is defined as the number of repetitions of a wave occurring waves in 1 second.
Bill is making waves on a rope with one end attached to a wall. When he starts moving the rope quickly, the frequency of the waves created on the rope doubles.
The energy that is transferred to the wall is propotional to the frequency of the waves.
Hence the energy that is transferred to the wall will be doubled.

Jose Altuve hits a fastball with a velocity of 49.1 m/s (109.9 mph) at an angle of 22º. If left field is 96 m (315 ft) away, will this be a home run?
Answer:
Yes
Explanation:
The given parameters are;
The speed with which the fastball is hit, u = 49.1 m/s (109.9 mph)
The angle in which the fastball is hit, θ = 22°
The distance of the field = 96 m (315 ft)
The range of the projectile motion of the fastball is given by the following formula
[tex]Range = \dfrac{u^2 \times sin(2\cdot \theta)}{g}[/tex]
Where;
g = The acceleration due to gravity = 9.81 m/s², we have;
[tex]Range = \dfrac{49.1^2 \times sin(2\times22^{\circ})}{9.81} \approx 170.71 \ m[/tex]
Yes, given that the ball's range is larger than the extent of the field, the batter is able to safely reach home.
