Answer:

25.818 kg

Explanation

If 2.2lbs is 1 kg then 56.8 lbs is x kg

2.2 (lbs) _____1 (kg)

56.8 (lbs)_____x (kg)

We multiple first diagonally 56.8×1= 56.8

Then we take the result and we divide it with the number diagonally to x so

56.8÷2.2= 25.818

Item 19 A student with arms outstretched stands on a platform that is rotating with a constant angular speed. The student then p
nadezda [96]

Answer:

An increase in angular speed due to conservation of energy priciple.

Explanation:

This leads to a decrease in your moment of inertia. This means that your angular velocity must increase as a result of conservation of energy principle and therefore you will spin faster.

It's also the same way this conservation of energy principle applies to ice skaters that makes them spin faster when they suddenly draw their arms inwards.

a crane lifts a 35000 N steel girder a distance of 25 m in 45 s. How much power did the crane require to lift the girder
Angelina_Jolie [31]
Hello.

The formula for Power is Work divided by Time; however, we do not have our value for Work - yet.
To find for the Work inputted, we need to use its formula: Force * Distance.

Let's multiply our Force by our Distance. Remember that our Force is always  measured in Newtons (N), and our Distance is measured by Meters (M).
35,000 * 25 = 875,000 J (Unit for Work is "J" or "Joules")

Now that we have the value for Work, let's apply it to our Power formula.
P = 875,000 / 45; 19,444.44~

The Power required to lift the girder is 1944.44~ W (Unit for Power is "W" or "Watts").

I hope this helps!

Joe is an athlete and ran today. His exercise heart rate is 130. His THRZ is 147-179
Katyanochek1 [597]

Answer:

The correct option is;

a) Mike, he is within his target heart rate zone

Explanation:

The Target Heart Rate Zone (THRZ) is the range of the percentage of a person's maximal heart beat rate (MHR) targeted to be achieved during exercising. It is a very good way to gauge the comparative intensity of a person's exercise

Whereby, Joe's heart beat rate is below his THRZ and Mikes heart beat rate is within his THRZ, Mike is working harder.

Hence the correct option is (a) Mike, he is within his target heart rate zone.
