Answer:
128805.2988 cm squared or 128000 to 3 significant figures.
Explanation:
Area of a circle : pi times radius squared or 
pi times 4.1×10^4 cm = 41000 pi or 128805.2988
Answer:
2500m
Explanation:
given,
initial velocity(u) = 5m/s
final velocity (v) = 0 m/s ( as he/she stopped riding after 1000 secs)
time = 1000 secs
distance(s)=?
now,
s=( u+v ) ×t /2
=(5+0)×1000/2
=2500 m
hence, he /she travels 2500m far
Answer:
travels along a curve due to uniform gravity
Explanation:
General relativity
The theory was developed by Albert Einstein , it is the theory of gravitation , according to which , the gravitation effect which is observed between the masses , is the resultant of their warping of the space time .
In general relativity , the equivalence principle is the equivalence of inertial gravitational mass .
According to which , the light bends due to gravitational forces ,therefore , the light travels along a curve because of uniform gravity .
Pints and ounces are both very small while gallons are very large so I would say about a Quart.
Answer:
Decreases
Explanation:
When an electron is released from rest in a region of space with nonzero electric field. And when the electrons move the electric potential energy of the system decreases because the kinetic energy increases and for the total energy to remain constant the potential energy must reduce.
An electron is accelerated in an electric field meaning its kinetic energy increases.
