The answer is C.) Work

Force is not a quantity of the transfer of energy. An example of force would be when you push on a wall. You are applying force on a wall but the wall doesn't move. Thus, there is no transfer of energy.

The SI unit for force is Newtons (N)

Motion is a representation of force, not a quantity of the transfer of energy. When you see a ball rolling on the ground, this is because something pushed it and applied force, or the force of gravity is pulling down on it. There is also no transfer of energy in motion.

The SI unit for motion is Meters Per Second (m/s)

Work is the quantity of the transfer of energy. If you were to push on a door and it opens, energy has been transferred from your arms to the door; thus, there is work present.

The SI unit for work is a Watt (W), or Joules per Second (j/s)

Let me know if you need any clarifications, thanks!

natulia [17]

Answer:

changing the polarity or direction of the battery changes the sign of the voltage and the current

Explanation:

The sign of current and voltage are due to established conventions.

The way that a DC circuit with negative current values is by changing the polarity of the power source or by inverting the battery, this creates that the electrons move in the opposite direction

Changing the battery also changes the direction of the power difference, since the potential from positive to negative, in most cases negative is assigned a potential of zero volts

In summary, changing the polarity or direction of the battery changes the sign of the voltage and the current

To tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.50•10^6 N, one at an angle 19.0° west of north, a

Answer:

Work done by a tug boat, W = 1.735 x 10⁸ J

Explanation:

Given,

The of each tugboat, F = 1.5 x 10⁶ N

The angle of each tugboat forms with the resultant force, θ = 19°

The displacement of the supertanker, s = 710 m

The individual tugboat will be responsible for the displacement, d = 710/2

= 355 m

The displacement component in each tugboat direction = 355 · sin θ meter

Therefore, the work done by each tugboat is

W = F x S joules

Substituting the values in the above equation

W = 1.5 x 10⁶ x 355 · sin θ

= 1.735 x 10⁸ J

Hence, the work done by each tugboat is, W = 1.735 x 10⁸ J

A grocery store sells 5-lb bags of mangoes. You purchase four bags over the course

sergij07 [2.7K]

Answer:

Accurate

Explanation:

Accuracy deals with the nearness of the measured values to the true value.

Precision is the ability to reproduce a certain result in a repeated fashion.

From the given masses of the 5-lb bags, we see that the mean value of the measurement is 5.1-lb
This value is very close to the original mass of the bag which is 5-lb bags.
We can say the reading is accurate

The reading is not precise because, the same weight is not reproduced. Different values of weight was reported from each of the measurement process.
