True or False: Newton's Law

Physics
1 answer:
Ray Of Light [21]4 years ago
6 0

Answer:

True

Explanation:

Newtons Law states that "When a net force acts on a body, it produces acceleration in the body in the direction of the net force. The magnitude of acceleration is directly proportional to the net force and inversely proportional to its mass."

So, it's mathematical form is

=> a ∝ F     (1)

=> a ∝ \frac{1}{m}

Combining the proportionality

=> a ∝ \frac{F}{m}

=> F ∝ ma

Using k as proportionality constant.

=> F = kma

Here k = 1

=> F = ma (Proved)

A woman drives 6 miles, accelerating uniformly from rest to 70 mph. How long does it take for her to reach 70 mph?
Morgarella [4.7K]
Using the two kinematic equations that can be used for this problem are:
Vf = Vi + at and d=Vit +(1/2)*at^2
Since Vi (initial velocity) = 0 

The equations can further be simplified where a is the acceleration, t is the time, Vf is the final velocity which is 70 miles per hour and d is 6 miles

Vf = at
70 = at
a = 70/t---equation 1

d=(1/2)*a*(t^2)
6 = (1/2)*a*(t^2) ---equation 2

Substituting equation 1 to equation 2.
6= (1/2)*(70/t)*(t^2)
6= 35t
t= 0.17142 hours or 10.28571 mins or 617.14 sec

The loudness of a sound is determined by the __________, or height, of the sound wave.
NISA [10]

Answer: Aplitude

Explanation: Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. Amplitude is measured in decibels.
