The relative angle at the knee changes from 0 to 85 degrees during the knee flexion phase of a squat exercise. If 10 complete sq

uats are performed, what is the total angular distance undergone at the knee (in degrees)?

Answer: the total angular distance undergone at the knee is 1700°

Explanation:

You know that in a knee flexion, the angle goes from 0° to 85.

Now, in one squat, the knee flex and the angle goes from 0° to 85° (85° of angular distance) and when the knee straigthens, the angle goes from 85° to 0° (another 85° of angular distance)

So in one squat, the total angular distance undergone at the knee is d = 85° + 85° = 170°

and if in one squat, the angular distance is 170°, in ten, the angular distance will be ten times that number:

d = 10*170° = 1700°

aluminum has a density of 2.7 g/cm3. if a chuck of aluminum with a mass of 16 g is placed in a graduated cylinder partially fill
sweet-ann [11.9K]
When placing the piece of aluminium in water, the level of water will rise by an amount equal to the volume of the piece of aluminum.
Therefore, we need to find the volume of that piece.

Density can be calculated using the following rule:
Density = mass / volume 
Therefore:
volume = mass / density
we are given that:
the density = 2.7 g / cm^3
the mass = 16 grams
Substitute in the equation to get the volume of the piece of aluminum as follows:
volume = 16 / 2.7 = 5.9259 cm^3

Since the water level will rise to an amount equal to the volume of aluminum, therefore, the water level will rise by 5.9259 cm^3

A man does 500 j work pushing a car a distance of 2m how much force does he apply
olasank [31]

Answer: 250 N

Explanation:

Use equation for work

W=F*d

d=2m

W=500J

F=?

-----------------------

W=Fd

F=W/d

F=500J/2m

F=250N
