Moon does not have atmosphere as we have on earth. on the earth, you can see the ground in someone’s shadow; on the moon, you can’t—the shadow is deep black. explain the scientific reason behind this difference

One of the scientific characteristics that can make the difference between the Earth and the moon is the so-called Rayleigh dispersion effect. This concept is identified as the dispersion of visible light or any other electromagnetic radiation by particles whose size is much smaller than the wavelength of the dispersed photons. Our atmosphere allows even our 'shadows' to be clear.

On the moon under the absence of the atmosphere or any other mechanism that allows absorbing or failing to re-irradiate sunlight towards the area in its shadows, which makes the shadows on the moon look darker.

Answer from: Quest

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

$f\alpha \frac{dp}{dt}$

⇒ $f= k \frac{dp}{dt}$

here k is the proportionality constant whose value is 1.

$f=\frac{dp}{dt}$

$f= \frac{d[mv]}{dt}$

$f= m\frac{dv}{dt} +v\frac{dm}{dt}$

$f=ma+v\frac{dm}{dt}$ [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.

Apositive rod is placed to the left of sphere a, and the spheres are separated. which best describes the spheres? sphere a is negative and sphere b is positive because protons from sphere a are attracted to the rod and move to sphere b. sphere a is negative and sphere b is positive because electrons from sphere b are attracted to the rod and move to sphere a. sphere a is positive and sphere b is negative because electrons from the rod move to sphere b and protons then move to sphere a. sphere a is positive and sphere b is negative because protons move from sphere b to the rod and also to sphere a.
