Its the rate of doing work.
B is the correct answer for sure bro
Answer and Explanation:
The binary system is a star system about half of the star are the part of the binary system
The important binary systems are
- Visual binary : in visual binary system the two stars resolved visually with nay sort of optical device the orbit of binary orbit is very large about center of mass.
- Spectroscopic binary : in this binary system the stars are detected by close analysis of light and after detection it is found that there are two seller spectrum present instead of one.
- Eclipsing binary : eclipsing binary system is a several types of variable stars this binary system is very important in astrophysics
Answer:
The phenomenon of diffraction.
Explanation:
Diffraction of light that resembles the behavior of waves in water made scientists think that light have a wave nature.
Answer:
Explanation:
<u>Kinematics equation for first Object:</u>
but:
The initial velocity is zero
it reach the water at in instant, t1, y(t)=0:
<u>Kinematics equation for the second Object:</u>
The initial velocity is zero
but:
it reach the water at in instant, t2, y(t)=0. If the second object is thrown 1s later, t2=t1-1=1.02s
The velocity is negative, because the object is thrown downwards.
