Answer:
Explanation:
A wave is a phenomenon that travels through a material medium without any permanent effect on the medium. It can be classified as mechanical or electromagnetic waves. And the two major types are transverse and longitudinal.
From the given question;
1. Longitudinal waves e.g sound waves, waves in a spring'
2. Frequency (number of cycles per second).
3. Wavelength of the wave. Measured in meters.
4. Transverse waves e.g light waves, water waves.
5. Wave speed.
6. Electromagnetic waves e.g ultraviolet waves, X-rays etc.
7. Amplitude.
8. Hertz.
9. Rarefaction
10. Compression
The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land.
not giving you the answer but hopefully this gives a hint
Answer:
The displacement, velocity and time is 20.4 m, -4.52 m/s and 3.624 sec.
Explanation:
Given that,
Initial velocity =15.0 m/s
Height = 10 m
We need to calculate the displacement at 2 sec
Using equation of motion
Put the value into the formula
At 2 sec,
We need to calculate the time
Using equation of motion again
At ground s = 0,
Neglect the negative term because the time is not negative
We need to calculate the velocity
Using formula of velocity
Hence, The displacement, velocity and time is 20.4 m, -4.52 m/s and 3.624 sec.
