If the runner is running in a circular track then yes when something or someone is moving in a circular motion at a constant speed they are indeed accelerating. They’re accelerating because the direction of the velocity vector is changing
Answer:
A = 5.6μs
B = 178.57kHz
C = 2.8μs
Explanation:
A. It takes ¼ of the period of the circuit before the total energy is converted from electrical energy in the capacitor to magnetic energy in the inductor.
t = T/4
T = 4*t
T = 4 * 1.4 = 5.6μs
B. f = 1/T
Frequency is the inverse of period
f = 1 / 5.6*10⁻⁶
f = 178571.4286Hz
f = 178.57kHz
C. time taken for maximum energy to occur is T/2
t = 5.6 / 2 = 2.8μs
Answer:
The speed in the smaller section is 
Explanation:
Assuming all the parts of the pipe are at the same height, we can use continuity equation for incompressible fluids:
(1)
With Q the flux of water that is 
with A the cross section area and v the velocity, so by (1):
subscript 2 is for the smaller section and 1 for the larger section, solving for 
:
(2)
The cross section areas of the pipe are:
but the problem states that the diameter decreases 86% so 
, using this on (2):
600
mph
Velocity is the distance traveled in a given time, or
v
=
x
t
where
v
is velocity,
x
is distance and
t
is time.
Here,
x
=
3000
and
t
=
5.0
, so
v
=
x
t
=
3000
5
=
600
Don't forget units. Since the question's data is in miles and hours, the units will be miles per hour, or mph, so
3000
miles
5
hours
=
600
miles
hour
=
600
mph
