Answer:
10 m/s
Explanation:
Kinetic energy= 
mv² where m is mass and v is velocity.
We have to make v the subject so we should rearrange the equation
K=mv²
v²= 
(use algebra)
v²= 7/0.5×0.140
v²=100
v=√100
v=10 m/s
We can confirm this by using the kinetic energy formula.
K=×0.140×10²
K= 7 J
Hence it is proved that velocity is 10 m/s

<span>Your
mother is sure that you were driving too fast because
she knows how long it took you to get
home and how far
you traveled. </span>
If she gets her calculator out of her sewing box and divides
the distance you covered by the time it took you to cover the
distance, the answer she gets will be your average speed.
Given,
Current (I) = 0.50A
Voltage (V) = 120 volts
Resistance (R) =?
We know that:-
Voltage (V) = Current (I) x Resistance (R)
→Resistance (R) = Voltage (V) / Current (I)
= 120/0.50
= 24Ω
∴ Resistance (R) = 24Ω
