Answer:
: It Decreases.
As the spacecraft gets farther and farther from Earth, the gravitational
forces between the spacecraft and the Earth decrease.

Answer:
A
Explanation:
half life is the time taken for a radioactive isotopes to dissociate
Answer:
a)

b)
m = 48lb
c)
b = 144.76lb
Explanation:
The general equation of a damping oscillate motion is given by:
(1)
uo: initial position
m: mass of the block
b: damping coefficient
w: angular frequency
α: initial phase
a. With the information given in the statement you replace the values of the parameters in (1). But first, you calculate the constant b by using the information about the viscous resistance force:

Then, you obtain by replacing in (1):
6in = 0.499 ft

b.
mass, m = 48lb
c.
b = 144.76 lb/s
Not so fast.
I think you're using 'accelerating' to mean 'speeding up', but you really need
to be more careful with it. "Acceleration" means ANY change in speed OR
direction.
If an object's speed to the left is decreasing, or its speed to the right is
increasing, then the net force on the object must be directed towards
the right.
If an object is moving with constant speed in a circular path, then it's
constantly accelerating, because its direction is constantly changing.
The force on it is always directed towards the center of the circle, so
there's one point on the path where the force is directed straight to the right.
