Answer:
Period = 6 seconds.
Explanation:
Given the following data;
Number of oscillation, n = 10
Time = 1 minute to seconds = 60 seconds
To find the period;
A period is the number of revolutions in a minute.
Substituting into the equation, we have;
Period = 6 seconds.
Answer:
2s
Explanation:
The position function of the motion can be expressed as:
where 
is the origin where the particle starts off, 
and a = <1,2,0> m/s2. In the 3-coordinate system it can be written as
For the particle to hit the 2x+y-z=4 plane then its coordinates must meet that criteria
t = 2 or t = -1
Since t can only be positive we will pick t = 2s
Answer:
ω, the angular frequency of the source equals 377 rad/s
Explanation:
From the question, V(t) = V cosωt.
Now, ω = the angular frequency of the sinusoidal wave is given by
ω = 2πf where f = the frequency of the source = 60 Hz
So, the angular frequency of the source ,ω = 2π × the frequency of the source.
So, ω = 2πf
ω = 2π × 60 Hz
ω = 120π rad/s
ω = 376.99 rad/s
ω ≅ 377 rad/s
So, ω, the angular frequency of the source equals 377 rad/s
Average speed=total distance travelled/time
