Answer: Hello! Here your answer......
Force = 10.244 Newtons
b) No of oscillations = 0.88
Explanation:
Since the block executes SHM we can write it's position as function of time as
ω is the natural frequency of the system
A is the amplitude of the system
Thus accleration of the block
Thus using the given values at t= 3.50 sec we can calculate the acceleration as
thus force can be calculated using newtons second law as
b)
Now no of oscillations can be obtained as
no of oscillations in 3.50 seconds = 3.50/3.976 = 0.88

Factor out 8 and then facotr and u get
8/9(9x+1)(9x-1
Answer:
The car travel 2.52 m
Explanation:
This problem gives us the time and speed of the car with the echolocation system, and they ask us for the distance traveled, we can use the report motion equation.
Let's start by calculating the relative speed of the two cars, which in this case is the initial mass because the second vehicle is at rest.
v = d / t
d = v t
d = 14 0.18
d = 2.52 m
The car travel 2.52m

Answer:
Visible light
Explanation:
Electromagnetic spectrum is the classification of the electromagnetic waves based on their frequency and wavelength. In order from the shortest to the longest wavelength, we have
Gamma rays
X-rays
Ultraviolet
Visible light
Infrared radiation
Microwaves
Radio waves
All these waves are invisible to human eye, except for the visible light part. Visible light is perceived as a different color by the human eye, depending on the wavelength of the light. In particular, we have:
Violet: 380 - 450 nm
Blue: 450 - 495 nm
Green: 495 - 570 nm
Yellow: 570 nm - 590 nm
Orange: 590 nm - 620 nm
Red: 620 nm - 750 nm
