Answer:
Newton's First Law of Motion.
Explanation:
Newton's first law of motion states that an object continues to stay in its state of rest, or of uniform motion, until acted upon by an external force.
So in the case of the golf ball here, the ball stays in its state of rest, on the tee, until the golf club hits it, i.e. , applies an external force on it.
Hence we can say that Newton's First Law of Motion is the principle which is most suitable for explaining this phenomenon.
Answer:
The greater weight increases the terminal velocity by acting as an extra force against gravity and air resistance.
Answer:
166 W
Explanation:
Power is the rate at which work is done.
The work done by Jill is the product of the weight of the pail and the height it moves.
The weight is the product of the mass and acceleration of gravity, <em>g</em>. Taking <em>g</em> as 9.81 m/s², the weight is
<em>W</em> = (6.90 kg)(9.81 m/s²) = 67.689 N
Work done = (67.689 N)(27.0 m) = 1827.603 J
Power = (1827.603 J) ÷ (11.0 s) = 166 W
Answer: A PN-junction diode is formed when a p-type semiconductor is fused to an n-type semiconductor creating a potential barrier voltage across the diode junction
Explanation: hope this helped
If a person drives 4 miles east, then 3 miles west, here are the facts:
They are 1 mile away from where they started.
They have driven a total of 7 miles.
