Weight is a measure of the force of gravity acting on an object. According to Newton's laws of motion, force is directly proportional to both mass and acceleration, and the equation for force is F = m * a, where m = mass and a = acceleration.
Answer:
(a) burnout speed at apogee in the external tank disposal orbit=7.82 km/sec
(b) ΔV required for the OMS-1 =0.066 km/sec
(c) ΔV required for the OMS-2 =0.045 km/sec
(d) This part of the question is explained in detailed way in the attached file.
Explanation:
Detailed explanation of all the parts of the question are given in attached files.
The magnitude of the force acting on the object lying on a flat surface without moving is 10 N.
The given parameters;
- magnitude of force on the object, F = 10 N
- angle between the object and the horizontal flat surface = 0⁰
Apply Newton's second law of motion to determine the magnitude of the force on the object.
Due to the position of the object, the magnitude of the force acting on it is calculated as;
Therefore, the magnitude of the force acting on the object is 10 N.

Answer: 0.45
Explanation:
First note that the body that causes the body to move is its moving force (Fm) which is 9.0N
Since the mass of the body is 2.0kg, the weight will be;
W= mg = 2×10
W= 20N
For static body, the frictional force (Ff) acting on the body is equal to the moving force (Fm) since both forces acts along the horizontal on the body.
Ff = Fm = 9.0N
The normal reaction (R) on the body will also be equal to its weight(W) since weight acts downwards and the reaction acts in the opposite direction (upwards).
R = W = 20N
Ff = nR taking 'n' as coefficient of static friction between the drawer and the cabinet.
9.0 = 20n
n = 9/20
n = 0.45
Answer: Equinox comes from the Latin words aequi, which means "equal," and nox, which means "night." The vernal equinox is considered the first day of spring: finally, the day and night are of equal length.
