The mathematical symbol for period is O A. A O B. v OC. T O D. f
1 answer:
Answer: C. T
Explanation:
Period is a unit of time; and in the context of waves or oscillations it is defined as <em>"the </em><u><em>time </em></u><em>elapsed between two equivalent points on the wave or oscillation".</em>
<em />
It is important to note Period (denoted by ) is one of the most important factors (along with the amplitude, frequency and velocity) to describe and characterize a wave.
In addition, Period has an inverse relation with the frequency , this means that if we are given the frequency of a wave, we can inmediatly know its Period.

The mass of the car [m] = 1.2×10^3 kg.
The initial speed of car[u]= 0 m/s
The final speed of car [v]= 20 m/s
We are asked to calculate the force required to increase the speed from 0 to 20 m/s.
The momentum of a substance is defined as product of mass and velocity.
Mathematically momentum p=m×v [Here m is the mass]
From Newton's second law we know that-
[here t is the time]
[ANS]
Hence the correct answer to the question is C.
Answer:
<h3>The answer is 16.67 m/s²</h3>Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>16.67 m/s²</h3>Hope this helps you
