Time = distance/time
time(hours)= 10/40
time(hours)=0.25
=15 minutes
Answer:
6.34 x 19^14 Hz
Explanation:
Wavelength, λ = 473 nm = 473 x 10^-9 m
the relation between the frequency and the wavelength is given by
v = f x λ
where, v is the velocity of light in vacuum which is equal to 3 x 10^8 m/s.
So, f = v / λ
f = ( 3 x 10^8) / ( 473 x 10^-9)
f = 6.34 x 19^14 Hz
The magnitude of the maximum force that the tow rope can apply to the skier without causing her to move will be 81.03 N,
<h3>What is the friction force?</h3>
It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).
It is defined as the product of the coefficient of friction and normal reaction.
On resolving the given force and acceleration. Mathematically aion in the different components and balancing the equation gets. Components in the x-direction.
The normal force is balanced by weight;
N = mg
The magnitude of the maximum force that the tow rope can apply to the skier without causing her to move is;
F = μN
F= μmg
F=0.14 × 59 kg × 9.81 m/s²
F = 81.03 N
Hence, the magnitude of the maximum force will be 81.03 N,
