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:

Explanation:
From the question we are told that:
Weight 
Altitude
Let
Radius of Earth 
Gravity 
Generally the equation for Gravity at altitude is mathematically given by


Therefore
Weight at sea level


Weight at 6.33 altitude


Therefore



Answer: Weight truck+load = 29.4×
N
Explanation: When an object floats in a fluid, there is an upward force, caused by the liquid, acting on the object that opposes the weight of the immersed object. This force is called <u>Buyoyant</u> <u>Force</u> and is determined by:
B = d*V*g
where
d is density of the fluid;
V is volume of liquid displaced due to the immersed object;
g is acceleration due to gravity;
For the truck, the system is in equilibrium, which means buyoyant force is equal weight. Then:
Volume displaced is
V = 10*8*0.0375
V = 3 
Density of water: 1000kg/

= 1000*3*9.8
= 29.4×
N
The weight of the truck and the load is 29.4×
Newtons
Answer:
Answer: 18.3 km/s
Explanation:
If a satellite in Molniya orbit has an apogee at 48.000 km as measured from the center of Earth, and a velocity of 3.7 km/s. Its velocity in at perigee would be 18.3 km/s.
Answer: -1.27 m/s^2
Explanation:
a = - V^2 / 2x
a = -(25^2) / 2 x (246) = 1.27 m/ s^2
Therefore the linear acceleration of the wheel is - 1.27 m/s^2
