Answer:
1.25377 m/s²
Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
= Coefficient of friction
= Slope
From Newton's second law
Applying to the above equation and
The acceleration of the same skier when she is moving down a hill is 1.25377 m/s²
When the amplitude varies, it means twice as much.
<h3>Which instances of sinusoidal waves are there?</h3>Simple harmonic motion, such the swinging of a pendulum or the weight of a weight on a spring, produces a sinusoidal relationship between position and time. Sound and water waves, for example, can be visualized as sinusoids.
Given:
if the string is given four times as much power.
According to the power that a sinusoidal wave on a stretched string transmits,
P = μω^A^2v
Where μ=mass per unit length, w= angular speed, A= amplitude, v= wave speed, P= power delivered.
P ∝
Here, the only terms we need are power and amplitude.
A =K
Where K is constant
Here, "power become quadruple" refers to four,
A =
A =2
Therefore, an increase in amplitude by a factor of two is equivalent to a twofold increase.
