The correct answer is C. Universal Gravitation (it was written by Issac Newton)
The density of silver is ρ = 10500 kg/m³ approximately.
Given:
m = 1.70 kg, the mass of silver
t = 3.0 x 10⁻⁷ m, the thickness of the sheet
Let A be the area.
Then, by definition,
m = (t*A)*ρ
Therefore
A = m/(t*ρ)
= (1.7 kg)/ [(3.0 x 10⁻⁷ m)*(10500 kg/m³)]
= 539.7 m²
Answer: 539.7 m²
Answer:
a state in which opposing forces or influences are balanced.
Explanation:
Answer:
The time is 1206 years.
Explanation:
Given that,
Distance = 27000 ly

Speed = 0.9990c
We need to calculate the time
Using formula of speed


Put the value into the formula


We need to calculate the time dilation the clock on the spaceship
Using formula of dilation time




The time convert in years
We know that,

So, the time is


Hence, The time is 1206 years.
