Answer:
3.2m
Explanation:
Given parameters:
Frequency of the FM radio = 9.23 x 10⁷Hz
Velocity of the waves = 3 x 10⁸m/s
Unknown:
Wavelength of the wave = ?
Solution:
To solve for the wavelength of the wave, we need the velocity equation;
Velocity = frequency x wavelength.
Radio waves are all electromagnetic radiations produced by both electrical and magnetic fields perpendicularly oriented to one another.
Since the unknown is wavelength, we solve for it:
3 x 10⁸ = 9.23 x 10⁷ x wavelength
wavelength = 
wavelength = 3.2m

Answer:
her acceleration is 1 m/sec
Explanation:
The following information is given in the question
The initial velocity is 5 m/s
After 10 seconds, she would be moved at 15 m/s
We need to find the acceleration
As we know that
Acceleration = Change in speed ÷ time
Acceleration = (15 - 5) ÷ (10)
= 1 m/sec
Hence, her acceleration is 1 m/sec
The same would be considered
Answer:
859.07 N
Explanation:
u = Initial velocity = 1.9 m/s
v = Final velocity
s = Displacement = 0.165 m
a = Acceleration
m = Mass = 890 kg
Equation of motion
Force
The magnitude of the average force on the bumper is 859.07 N
Three characteristics of chemical reactions are 1. change of color, 2. change of state and 3. evolution of a gas. the three characteristics of nuclear reactions are one element to another element, measurable changes in mass, not affected by measure. <span />
