Answer:
,Assume that the average volume of an adult human body is one-tenth
cubic meter (0.10 m) and that there are two billion (2.0 x 109)
adults in the world.
a. What would be the total volume of all the adults in the world?
b. Compute the length of one edge of a cubic container that has a
volume equal to the volume of all the adults in the world.
Answer:
Explanation:
Time dilation formula is
T = T₀ / √ 1-v²/c²
T₀ is time elapsed in moving reference , T time elapsed in stationary reference.
Here T₀ = 1 second
T = 1/√ 1-0.9² = 1/.4358 = 2.3 second
So 2.3 second will pass for each second on moving reference.
Answer:
Explanation:
We can use Newton's Universal Law of Gravitation to solve this problem:
., where 
is acceleration due to gravity at the planet's surface, 
is gravitational constant 
, 
is the mass of the planet, and 
is the radius of the planet.
Since acceleration due to gravity is given as 
, our radius should be meters. Therefore, convert 
kilometers to meters:
.
Now plugging in our values, we get:
,
Solving for :
.
