<span>Most of the anaerobic bursts lasts for between 30 seconds and two minutes. The duration is short because oxygen is the major driving force of all the biological process in the body.</span>

Well It Is Defined As " A Brief Burst Of Intense Exercise. Any Physical Activity That Is Short, Explosive, And Depends Solely On The Energy That Is Stored In A Muscle And Not On Oxygen Intake."

A metal block has a density of 5000 kg per cubic meter and a mass of 15,000 kg. What is its volume?
Naily [24]

Taking into account the definition of density, the volume of the metal block is 3 m³.

<h3>What is density</h3>

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Volume of the metal block</h3>

In this case, you know that:

  • Density= 5000 \frac{kg}{m^{3} }
  • Mass= 15000 kg
  • Volume= ?

Replacing in the definition of density:

5000 \frac{kg}{m^{3} } =\frac{15000 kg}{volume}

Solving:

volume×5000 \frac{kg}{m^{3} }= 15000 kg

volume= \frac{15000 kg}{5000 \frac{kg}{m^{3} }}

<u><em>volume= 3 m³</em></u>

In summary, the volume of the metal block is 3 m³.

A bicyclist increases her speed from 4.0 m/s to 6.0 m/s. The combined mass of the bicyclist and the bicycle is 55 kg. How much w
11Alexandr11 [23.1K]
Kinetic energy of the horse and rider = 1/2 (mass) (speed)²

At 4.0 m/s :  KE = 1/2 (55kg) (4 m/s)²  =  440 joules

At 6.0 m/s :  KE = 1/2 (55kg) (6 m/s)²  =  990 joules

She increased the kinetic energy of herself and her vehicle by 550 joules,
so she must have put at least that much work into it.

Let this oscillator have the same energy as a mass on a spring, with the same k and m, released from rest at a displacement of 5
allochka39001 [22]
There are a lot of same examples that you may have worked before, where the mass on a spring uses a classics when it comes to mechanics. So in this system, always put in your mind that there is an enormous quantum standard that one can use in the equation. It should be 2.10x10 raise to a negative sixth. J.

If you are given time and distance, you can determine power if you know force. watts. energy. joules.
DENIUS [597]
If you are given time and distance, you can determine power if you know force. watts. energy. joules.

Answer is joules.     

Power is defined as the rate of doing work. Hence power = work / time then you obtain watts. Work is the product of force and displacement (distance). Hence in formula, w = F x s. In which the S.I unit of work is joule in the product. This is what you have to obtain in order to calculate for power.
