Answer:
the questions they could ask would be:
how much will the temperature change?
how much pressure will there be?
how durable does the equipment need to be?
how do we know if we will run into a water pocket or a magma pocket?
Explanation:
Answer:
Explanation:
The air pressure inside a car tire is 3 atm = 303975 Pa
The force of 41,500 N of force pushing out on the tire.
We need to find the surface area of the inside of the tire. The pressure acting on an object is given by :
So, the surface area of the inside of the tire is .
Answer:
Final angular velocity = 2.15rad/s
Explanation:
The final angular velocity can be determined using the equation:
L=Ii × wi
L= (Ii + II) × wf
Where I is the moment of inertia of the 2nd cylinder and wf is the final angular velocity.
Given:
Ii=12.6kgm^2
I=41.8kgm^2
Wi=9.28rad/s
Ii ×wi= (Ii + I)×wf
12.6×9.28 = (12.6+41.8)×wf
116.93= 54.4wf
Wf=116.93/54.4
Wf= 2.15rad/s
Explanation:
For a circular orbit v= with G = 6.6742 ×
Given m = 6.42 x 10^23 kg and r=9.38 x 10^6 m
=> v = 2137.3 m/s
I hope this is the correct way to solve
