☄ <u>Universal</u><u> </u><u>Gravitational</u><u> </u><u>Constant</u><u>(</u><u>G</u><u>)</u>
Gravitational constant is a constant of proportionality when F(Gravitational force) is proportional to product of masses and inversely proportional to the distance between them.
- It can be defined as:- Universal gravitational constant is the magnitude of the force between a pair of 1 kg masses that are kept 1 metre apart.
- The SI unit of G is N m²/kg² and the CGS unit of G is Dyne cm² / g².

The value of G (universal gravitational constant) was found out by the scientist Henry Cavendish by using the sensitive torsion balance

It depends on how much you stress I recommend starting calm!
Explanation:
Answer:
a) I = 10⁻² W / m², b) β = 104.8 db
Explanation:
a) For this exercise we use the definition of decibels
β = 10 log
where I and Io are the intensities produced and the sound threshold
I₀ = 10⁻¹² W / m²
log \frac{I}{I_o} = β / 10
I = Io
let's calculate
I = 10⁻¹²
I = 10⁻² W / m²
b) each toad produces the same sound for which the total intensity is
I_total = 3 I
I_total = 3 10⁻² W / m²
expressed in decibels
β = 10 log ()
β = 104.8 db
if it is accelerating, there's an unbalanced force
Answer:
920 kg
Explanation:
You can figure this out using the equation for kinetic energy:
Given:
KE = 222640
v = 22
m = ?
