Hi there!
We can use the work-energy theorem to solve.
Recall that:

The initial kinetic energy is 0 J because the crate begins from rest, so we can plug in the given values for mass and final velocity:

Now, we can define work:

Now, plug in the values:

Solve for theta:

Light from other stars take longer to reach the earth because they are farther than our sun.
Answer:
You wouldnt fall you would be sucked and you would lose all air supply and you lungs would pop
Explanation:
Answer:

Explanation:
Given:
density, 
diameter of the pipe, 
pressure difference, 
In case of pitot tube, the velocity is given by:



Now we know that volumetric flow rate is given as:

where :
a= cross sectional area of the pipe
v= velocity of flow


Answer:
46,502,000 times
Explanation:
The question asked how many times back <em>and </em>forth, so you divide by 2 (so in half); and if it's 93,004,000 then you divide that by 2 which equals, 46,502,000.
