Answer:
Explanation:
The acceleration of an object is given by:
where
v is the final velocity
u is the initial velocity
t is the time interval it takes for the velocity to change from u to v
For the rocket in this problem,
u = 20,000 m/s
v = 24,000 m/s
t = 55.0 - 5.0 = 50.0 s
Substituting,
Answer:
The answer is zero.
Explanation:
For new york the answer is never.
Since the Earth's rotation axis is tilted 23.5 degrees with respect to its orbital motion around the Sun, one would have to be less than 23.5 degrees above or below the equator to have the Sun pass directly overhead (once per year).
Therefore ,
Zero days during one year is the sun directly overhead at noon in new york city.

Answer:
66.42 N
Explanation:
Torque is defined as the product of force and the perpendicular distance.
Where, r be the distance, f be the force and θ be the angle between the force vector and the distance vector
Case I :
F = 53 N, r = 28 cm = 0.28 m, θ = 90°
So,
case II :
F = ?, r = 0.28 m, θ = 53°
Let the force be F for the same toque.
F = 66.42 N
Thus, the force required is 66.42 N.
