Explanation:
what is the force
ican't under stand these question
Answer:
53 minutes
Explanation:
To solve this problem, we need to use common proportions to convert.
= 11.7km * 1mi/1.61km * 1hr/8.2mi * 60min/hr
≈ 53 minutes

Answer:
Displacement in Y direction is 0.434 m
Explanation:
initial velocity of the puck is 2.35 m/s at -22 degree
so here it is given as
final velocity is given as 6.42 m/s at 50 degree
so we have
now displacement in Y direction is given as

The three longest wavelengths for the standing waves on a 264-cm long string that is fixed at both ends are:
- 5.2 meters.
- 2.6 meters.
- 1.7meters.
Given data:
Length of the fixed string = 264cms = 2.64 meters
The wavelength for standing waves is given by:
λ = 2L/n
where,
- λ is the wavelength
- L is the length of the string
For n = 1,
= 5.2 meters
For n = 2,
= 2.6 meters
For n = 3,
= 1.7 meters
