Answer:
When in the graph the line is horizontal it states that the moving object is stationary
Explanation:
Answer:
Time take to fill the standing wave to the entire length of the string is 1.3 sec.
Explanation:
Given :
The length of the one end 
, frequency of the wave 
= 2.3 Hz, wavelength of the wave λ = 1 m.
Standing wave is the example of the transverse wave, standing wave doesn't transfer energy in a medium.
We know,
∴ 
λ
Where 
speed of the standing wave.
also, ∴ 
where 
time take to fill entire length of the string.
Compare above both equation,
⇒ 
sec
Therefore, the time taken to fill entire length 0f the string is 1.3 sec.
Answer: Dynamic - Static Flexibility
Explanation:
Answer:
161.86 N
Explanation:
mass of box m= 55.0 kg
weight of the box, mg= 55×9.81
g here is acceleration due to gravity =9.81 m/sec^2
coefficient of friction between the box and the surface μ= 0.3
the friction force F_s= μmg= 0.3×55×9.81
=161.86 N
to move the ball horizontal force required is 161.86 N
Acceleration of the car driven by Ariana = 4.6 m/s^2
Time taken to reach this acceleration = 10 seconds
Let us assume the final velocity of the car (V2) = x m/s
Initial velocity of the car driven by Ariana (V1) = 0 m/s
Then
Acceleration = (V2 - V1)/ Time taken
4.6 = (x - 0)/10
4.6 = x/10
x = 4.6 * 10 m/s
= 46 m/s
So the final velocity of the car Ariana was driving was 46 meters per second.
