<span>Every falling object on Earth will experience air resistance,
unless it's falling inside a vacuum chamber.
The air resistance will increase as the speed of the falling object
increases.
At the point when the air resistance equals the weight, there is no
acceleration, and the object will fall with constant speed after that.</span>
Answer:
Its level of output in the short run should not change
Explanation:
For a monopoly, maximization of profit is only possible if marginal cost is equal to marginal revenue. The new equipment will only change the fixed cost and not the marginal cost, thus there will be no change in the level of output.
Answer:
demand (an amount) as a price from someone for a service rendered or goods supplied.
<h2>Force = 49 N</h2>
Explanation:
The gravitational force of attraction on the surface of earth F = G M m/R²
Here G = gravitational constant = 6.67 x 10⁻¹¹
M = mass of the earth and m = mass of the body on the surface of earth .
R = radius of earth
In this question
mass of earth = 6 x 10²⁴ kg and its radius = 6 x 10⁶ m
The values are substituted in the above equation
F = 6.67 x 10⁻¹¹ x 6 x 10²⁴ x 5 / ( 6 x 10⁶ )² = 49 N
The mass will be attracted by 49 N of force .
Momentum = velocity * mass. Momentum is always conserved. The ball's momentum before the impact is 0.05Vo. After the impact, it is 105Vf. (Vf = final velocity). Because momentum is conserved, we know that:
0.05Vo = 1.05Vf...
Vo = 21Vf...
Vf = Vo / 21.
