How much work is done in pushing an object 7.0 m across a floor with a force of 50 N and then
attashe74 [19]

Answer:

35/2 J/s

Explanation:

Just use the 2 formulas

Work done = Force * distance moved

Power = Work done/time

WD = 7 * 50  = 350

Power = 350 / 20

= 35/2 J/s

Three small but dense objects are located in the x-y plane as shown in the figure. The objects have the following masses: mA = 3
satela [25.4K]

The x and the y coordinates of the center of the mass of this system will be 43.1 m and 3.12 m respectively.

<h3>What is the center of mass?</h3>

A location is established in relation to an object or set of objects in the center of mass. It is the system's average position across all of its components.

Given data;

There are three little objects that are densely spaced out in the x-y plane.;

The value of the masses

m₁=1.41 kg

m₂=2.55 kg

m₃=3.19 kg

\rm X_{cm} =\frac{ (W_1x_1 + W_2x_2 + W_3x_3)}{(W_1 + W_2 + W_3)} \\\\\  X_{cm} ==\frac{1.41 \times 2 + 2.55 \times 6 +3.19 \times 4}{1.41+2.55+3.19} \\\\  X_{cm} =4.31 \ m

\rm Y_{cm} =\frac{ (W_1y_1 + W_2y_2 + W_3y_3)}{(W_1 + W_2 + W_3)} \\\\\  X_{cm} ==\frac{1.41 \times 2 + 2.55 \times 4 +3.19 \times 7}{1.41+2.55+3.19} \\\\  X_{cm} =3.12 \ m

Hence, the x and the y coordinates of the center of the mass of this system will be 4.31 m and 3.12 m respectively.

The table below shows the number of fatalities in a coal mine in the United States from 1945 to 1985.
Sauron [17]
Number of fatalities means number of deaths among the miners.
Enforcing the Federal Coal Mine Health and Safety Act would definitely decrease the number of fatalities.

Therefore, the time period when the coal mine enforced the Federal Coal Mine Health and Safety Act to help miner would be the time period with the least number of fatalities.

Observing the given table and based on the above explanation, the best choice would be:
d. between 1975 and 1985
