v = ( 10)(3)
v = 30 m\ s <em>A</em><em>n</em><em>s</em><em> </em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em><em>.</em>
Answer:
yes, because you dont want to be mean and make her feel worse about it and hiv has something do with s3x not germs so yes go
Explanation:
Answer: Northwest.
Explanation:
After the collision the second object which was at rest would change its direction and move towards the Northwest. The object in motion was coming from the east and traveling towards the west, where it deflects against a stationery object which changes its direction to southeast. And the object which was at rest moves toward the northwest.
Answer:
A
Explanation:
When you pull the string the weight will experience a downward force and come closer to the vertical tube. And the angle between weight and hand through string is decreased so the angular velocity decreases
The star is moving toward the earth.
It is due to the phenomenon of the Doppler shift.
The <u>Doppler effect</u>, commonly referred to as "Doppler shift," is the <u>change in the wavelength </u>or frequency of waves as a result of an observer's motion in relation to the wave source.
It is possible to see this<u> apparent wavelength </u>change in the visible light emitted by stars and galaxies.
As a result, a star moving toward Earth appears to emit light with a shorter <u>wavelength</u> than a light source that is stationary. It is known as blueshift because <u>shorter wavelengths</u> cause the spectrum to shift toward the <u>blue end</u>.
While a star traveling away from us appears to shift its light towards longer wavelengths. Astronomers refer to this as redshift since it is closer to the <u>red end of the spectrum.</u>
<u />
As the spectrum of a particular star shows the hydrogen line appearing at a shorter wavelength of 480 nm in comparison to the laboratory measurements, that show the same hydrogen lines at a greater wavelength of 500 nanometers, that’s why we conclude that the star is moving toward earth.
