(a) As the car is moving with constant velocity, it means the rate change of velocity does not change, therefore the average acceleration of the car is zero.
Thus, there is no acceleration, when velocity is constant.
(b) Average acceleration,
Here, v is final velocity and u is the initial velocity and 
is the time interval.
As twelve seconds later, the car is halfway around the track and traveling in the opposite direction with the same speed, therefore
Thus, the average acceleration of the car is 
in the direction to the left.
From gas equations
PV/T = Constant
Then
P1V1/T1 = P2V2/T2, but V1 = V2
Therefore,
P1/T1 = P2/T2
P2 = (P1T2)/T1
P1 = 40 psi
T1 = 60°F = 288.706 K
T2 = 90°F = 305.372 K
Substituting;
P2 = (40*305.372)/288.706 = 42.31 psi
Then, gauge pressure would read 42.31 psi.
The answer is A. A folkway is a closely held belief by a specific group of people.
Answer: 1.32 m/s^2
Explanation:
Centripetal acceleration is given by the formula
a = ( v^2 ) / r
where a is centripetal acceleration, v is velocity and r is radius.
We know that,
v = 5 m/s
r = 19m
Now,
a = ( v^2 ) / r
a = ( 5^2 ) / 19
a = 25 / 19
a = 1.32 m/s^2
Answer:
Well AM/Fm is digitally using soundwaves for cars through signal, which we cant hear without one (radio). Concerts are in real life and use wavelegnths that we hear because it bounces off overytihing.
