<u>Answer:</u>

Prior to exercise, a proper warm-up of 10-15 minutes is extremely important to avoid injuries.

  1. Don't go too hard in the beginning and boost your activity level slowly. A good indication of a proper warm-up is that you feel sweat on your body parts.
  2. Don't overstretch right in the beginning as it can cause sore in your muscles and joints or stress fractures.
  3. Take a break if you feel sick or fatigues and use other drinks along with water to replace electrolytes and body fluids.

Answer:

Remember that the objective of warming up is avoiding problems when you are working out.

So the first thing that you need to have in mind is that you need to start slow, to prevent any possible harm.

You need to warm all your body, not only some parts of it.

when stretching, do not do it as you normally do, because it will relax your muscles, you should do dynamic stretching, this means that you keep your body in a position where there is no tension, and moving your body to generate tension, then relaxing again, then generating tension, and so on.

8–4. The tank of the air compressor is subjected to an internal pressure of 90 psi. If the internal diameter of the tank is 22 i
slamgirl [31]

Answer:

The stress S = 1935 [Psi]

Explanation:

This kind of problem belongs to the mechanical of materials field in the branch of the mechanical engineering.

The initial data:

P = internal pressure [Psi] = 90 [Psi]

Di= internal diameter [in] = 22 [in]

t = wall thickness [in] = 0.25 [in]

S = stress = [Psi]

Therefore

ri = internal radius = (Di)/2 - t = (22/2) - 0.25 = 10.75 [in]

And using the expression to find the stress:

S=\frac{P*D_{i} }{2*t} \\replacing:\\S=\frac{90*10.75 }{2*0.25} \\S=1935[Psi]

In the attached image we can see the stress σ1 & σ2 = S acting over the point A.

A rocket is launched with a velocity of 30 m/s at 40° to the horizontal. How far will it
steposvetlana [31]

Answer:

A. Rocket A will travel farther horizontally than rocket B.

Explanation:

This is because from the x axis, 40 m/s at 90 degrees travels directly vertical. 40 m/s at 70 degrees is slightly horizontal, so it will travel further horizontally.

Betty is sitting on of her surfboard out in the ocean. She is waiting for the perfect wave to come along so she can ride it in t
Ymorist [56]

Answer:

No they are not the same.

Explanation:

S=d/t Speed equals distance divided by time. Leah's wave took 10 seconds, and the distance was 6 meters.

6/10=.6

Betty's wave took 10 seconds, but the distance was 60 meters this time.

60/10=6

We know that 6 and .6 are not the same numbers, so we can see that the waves aren't the same.

I hope this helps!!
