Answer:
The human major features with the analogous of camera are mentioned.
Explanation:
There are the following major features of human eye which are analogue with the camera:
- Camera will have shutters which controls light entering into it, human eye consists of Diaphragm which also functions same.
- Both gives Real & inverted images.
- In camera film records image, in eye image is focused on retina and it is converted into electrical impulses.
- Pupil and iris acts as aperture of camera.
Answer:
Explanation:
given data= 34.2 m/s
we have to convert it into km/s
as we know that
1 km=1000 m
so 1 m= 1/1000 =0.001 km
now we know that 1 min=60 sec
so 1 sec=1/60= 0.016 min
therefore
34.2m/s = 34.2*m/sec =34.2*0.001 km /0.016 min
so 34.2 m/s =2.1 km/min
1. 
The Schwarzschild radius of an object of mass M is given by:
(1)
where
G is the gravitational constant
M is the mass of the object
c is the speed of light
The black hole in the problem has a mass of
where
is the solar mass. Substituting,
and substituting into eq.(1), we find the Schwarzschild radius of this black hole:
2) 242.8 solar radii
We are asked to find the radius of the black hole in units of the solar radius.
The solar radius is
Therefore, the Schwarzschild radius of the black hole in solar radius units is
Answer:
10⁻¹² W / m²
Explanation:
The feeble sound that a man can hear is of the vale which measures 0 on decibel scale . The intensity of sound in terms of J / m² .s is 10⁻¹² W / m² .
So the intensity of sound of monkey at 2.5 km must be 10⁻¹² W / m² .
Answer:
The correct answer is less momentum.
Explanation:
The momentum of an object is directly linked to the force exerted on that object. In a longer barrel, the shot cannonball will have a greater impulse changing to occur a larger momentum and therefore a higher speed will be applied to the bullet, contrary to what would happen in a shorter barrel.
