Answer:
Explanation:
Energy stored in a capacitor
= 1/2 CV²
C is capacitance and V is potential of the capacitor .
When capacitor is charged to 24 V ,
E₁ = 1/2 x 2.4 x 24 x24 = 691.2 J
When it is charged to 12 volt
E₂ = 1/2 CV²
.5 X 2.4 X 12 X12
= 172.8 J
I think the question need to use extrapolation. FInd the linear function of the first and second data. And then, the anwser is 5.4 liters.
Answer:E. an object will remain in uniform motion unless acted upon by a force
Explanation:
Answer:
The angular acceleration required is 0.1765 rad/ 
Explanation:
The radius of the bicycle wheel has a radius of 0.42 m.
The acceleration is for time, t = 6.8 seconds.
Initial angular velocity is given as
= 5.5 rad/s
Final angular velocity is given as
= 6.7 rad/s
Therefore from the formula for angular speed we get
=
+ (
t), where t is the time in seconds.
Therefore we get
6.7 = 5.5 + (6.8 ×
)
Therefore we get the angular acceleration,
= 
The angular acceleration required is 0.1765 rad/
