Only the masses of the objects and the distance between them. Nothing else affects the gravitational forces. Not even a concrete, steel, and Kryptonite wall between them.

distance between objects

masses of the objects

Explanation:

The magnitude of the gravitational force between two objects is given by

F=G\frac{m_1 m_2}{r^2}

where

G is the gravitational constant

m1 and m2 are the masses of the two objects

r is the distance between the two objects

By looking at the formula, we see that the gravitational force is affected only by two quantities:

- the masses of the objects, m1 and m2

- the distance between the objects, r

Describe how the doppler effect explains why a siren has a lower pitch as a fire engine moves away from you. How does the freque
Elena L [17]
The Doppler effect is the change in sound or light that occurs whenever there is motion between the source and its observer. The siren of the fire engine has a lower pitch as it moves away because the waves are now spread out causing a lower frequency and a lower pitch. High-frequency sound waves have a higher pitch and higher energy than low-frequency waves.

A 70-kg researcher absorbs 4.5 x 10^8 neutrons in a workday, each of energy 1.2 MeV. The relative biological effectiveness (RBE)
Inessa [10]

Answer:

effective dose is 1.2 mrem

Explanation:

given data

mass m = 70 kg

absorb  n = 4.5 ×  10^{8}

energy = 1.2 MeV

neutrons = 10

to find out

equivalent dosage

solution

we know here total energy in a day is

total energy = 4.5 ×  10^{8} × 1.2

total energy = 5.4 × 10^{14} eV

and total energy = 5.4 × 10^{14}  × 1.6 × 10^{-19}

so total energy = 8.64 × 10^{-5} J

and for mass 70 kg

it will be = 8.64 × 10^{-5}  / 70

= 1.23 × 10^{-4} rad

so

effective dose is here = 1.23 × 10^{-4} × 10 = 0.0012 rem

so effective dose is 1.2 mrem
