The force of gravity is less between to objects when the product
of their masses is smaller, or when they are farther apart.
Answer:
Explanation:
From the given information:
radius = 15 m
Time T = 23 s
a) Speed (v) = 

v = 4.10 m/s
b) The magnitude of the acceleration is:

a = 1.12 m/s²
c) True weight = mg
Apparent weight = normal force
From the top;
the normal force = upward direction,
weight is downward as well as the acceleration.
true weight - normal force = ma
apparent weight =mg - ma


= 0.886 m/s²
d)
From the bottom;
acceleration is upward, so:
apparent weight - true weight = ma
apparent weight = true weight + ma



= 1.114 m/s²
Speed is equal to distance divided by time.
Distances is equal to speed times time.
Time is equal to distance divided by speed.
Answer:
increase, increase
Explanation:
If the bore of an engine is increased without any other changes except for the change to proper-size replacement pistons. the displacement will<u> increase </u>and the compression rate will <u>increase</u>.
Further Explanation:
If the bore is increased, there are several benefits to this. There is more area for the valves this improves flow through the engine. The compression ratio will increase, thereby increasing thermal efficiency. The displacement also increases as the power output increase. Also, higher RPM will further increase power.
However, a decrease in bore will result in corresponding reduction in displacement and power output.
