Answer:
The period of the wave does not change looting the value that accompanies the time, the wavelength does not change since it is the constant that accompanies x.
We see that the amplitude is twice the amplitude of the incident waves. Since the wave is stationary the velocity is zero
Explanation:
In this exercise we are given the equation of two traveling waves, it is asked to find the resulting wave
u = f + g
u = 2 sin (x + t) + 2 sin (x-t)
we will develop double angled breasts
u = 2 [(sin x cos t + sin t cos x) + (sin x cos t - sin t cos x)]
u = 2 [2 sin x cos t]
u = 4 sin x cos t
The period of the wave does not change looting the value that accompanies the time, the wavelength does not change since it is the constant that accompanies x.
We see that the amplitude is twice the amplitude of the incident waves. Since the wave is stationary the velocity is zero
Answer:
1.0s
Explanation:
distance = 1/2 × acceleration × time2 + intial speed × time
Too easy way too easy I mean it’s easy
The amount of force needed by the truck to move the boulder is 200 N.
<h3>Force:</h3>
This can be defined as the product of mass and acceleration. The S.I unit of force is Newton or kgm/s²
To calculate the newton's of force a block needs to move, we use the formula below.
Formula:
- W = Fd............. Equation 1
Where:
- W = Work done by the truck
- F = Force applied on the boulder
- d = Distance moved by the boulder
Make F the subject of the equation
- F = W/d................. Equation 2
From the question,
Given:
Substitute these values into equation 2
Hence, the amount of force needed by the truck to move the boulder is 200 N.

Answer:
The potential energy has a maximum when the ball is a time that is half of the time for total travel
Explanation:
Generally potential energy is a the varies directly with the height according to this formula
and the ball attains a maximum height when the time is equal to half of the total time taken to travel
