Answer:
Explanation:
The acceleration of a circular motion is given by
where 
is the angular velocity and 
is the radius.
Angular velocity is related to the period, T, by
Substitute into the previous formula.
This acceleration does not depend on the linear or angular displacement. Hence, the amount of rotation does not change it.
The temperature of the substance giving off the heat decreases while the temperature of the substance receilving the heat increases. they leach what is called equlibrium point where heat energy can longer be exchanged hence equql temperature. this isThermal physics
Choice D, as if it takes up mass then it is matter
Answer:
a = 0.016 m/s^2
the airplane's acceleration is 0.016 m/s^2
Explanation:
Applying the equation of motion;
v^2 = u^2 + 2as ........1
Where;
v = final velocity = 47.5 m/s
u = initial velocity = 28.9 m/s
a = acceleration
s = displacement = 45300m
From equation 1, making a the subject of formula;
v^2 = u^2 + 2as
2as = v^2 - u^2
a = (v^2 - u^2)/2s
Substituting the given values;
a = (47.5^2 - 28.9^2)/(2×45300)
a = 0.015684768211 m/s^2
a = 0.016 m/s^2
the airplane's acceleration is 0.016 m/s^2
Answer:
Length of the stake will be 0.3623 m
Explanation:
We have given energy required to fully drive a stake into ground = 0.30 KJ = 300 J
Average resistive force acting on the floor is equal to F = 828 N
We have to find the length of the stake
We know that work done is given by
W = Fd, here W is work done , F is average force and d is the length of the stake
So 300 = 828×d
d = 0.3623 m
So length of the stake will be 0.3623 m
