Answer:
The acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s². So, the acceleration of the biker is NOT HIGHER than that of the car.
Explanation:
Given that,
acceleration of biker A= ?
Initial velocity of biker Vi = Om/s
Final velocity of biker Vf = 8m/s
Time taken (t) = 3 seconds
Since acceleration is the rate of change of velocity per unit time
i.e Acceleration = (Vf - Vi) / t
A = (8m/s - 0m/s) / 3s
A = 2.67 m/s²
To know which is higher, calculate the acceleration of the car
acceleration of car A= ?
Initial velocity of car Vi = Om/s
Final velocity of car Vf = 30m/s
Time taken (t) = 8 seconds
Acceleration = (30m/s - 0m/s) / 8s
A = 30m/s / 8s
A = 3.75 m/s²
Since, the acceleration of the biker is 2.67m/s² while that of the car is 3.75m/s², the acceleration of the biker is NOT HIGHER than that of the car.
Answer:
Explanation:
The frequency of an electromagnetic wave is given by
where
is the speed of light
is the wavelength
For the light wave in this problem, the wavelength is
So by using the equation above, we find its frequency:
The frequency of light can be found by using the formula f = c ÷ λ, where c is the speed of light and λ is the wavelength. By substituting these values into the formula, you can calculate the frequency of light with a given wavelength.
When you are given the wavelength of light and asked to find its frequency, you would use the formula c = fλ, where c is the speed of light (3.00 x 10⁸ m/s in vacuum), f is the frequency, and λ is the wavelength. To find the frequency, we rearrange this formula to get f = c ÷ λ. Given the wavelength λ = 6.33 x 10^-7 m, we can substitute these values into the rearranged formula to find the frequency:
f = (3.00 x 10⁸ m/s) ÷ (6.33 x 10^-7 m)
By calculating the above equation, you will find the frequency of the light with the given wavelength.

Answer:
Catch the wave.
The shape and curves are designed to capture sound waves from various directions and funnel them into the ear to start vibrating those ossicles. Cupping your hand behind the ear and pulling it forward makes sounds louder because your hand is snagging more sound waves.
Explanation:
It will receive more sounds
