Answer:
<h3>The power of headlight in series connection is 29.64 W</h3>
Explanation:
Given :
Power of headlight 
W
Power of starter 
W
Voltage of headlight and starter 
V
From equation of power,
For finding the resistance of headlight and starter,
⇒ For headlight,
Ω
⇒ For starter,
Ω
Since equivalent resistance,
Ω
So power in series is given by,
W
Could be c because it matches the question
Answer:
Her moment of inertia decreases causing her spin to speed up. The physics law behind this phenomenon is the conservation of angular momentum.
Explanation:
<em>Theory</em>
<u>The Law of conservation of angular momentum</u>
The angular momentum of a rotating body or a system remains constant unless it is acted upon by an external unbalance force.
Angular momentum = moment of inertia × angular velocity
The moment of inertia = mass×[perpendicular distance from axis of rotation]²
___________________________________________________________
⇒When skater draws in her outstretched arms the mass distribution get concentrated towards the axis of rotation so the moment of inertia of the body decrease.
But angular moment should conserve so angular velocity increases (spin increases)
<span>Sharon
is jumping from an 18-foot diving board with an initial upward velocity
of 4 ft/s. When Susan jumps, Megan throws a beach ball up to Susan with
an initial upward velocity of 16 ft/s from a height 5 feet off the
ground. To the nearest hundredth of a second, it will take C. 1.08 seconds for the ball to reach Sharon after she jumps. </span>
