A force of 25 newtons moves a box a distance of 4 meters in 5 seconds.
Svetllana [295]

Answer:

100 Nm and 25Nm/s.

Explanation:

<u>Given the following data;</u>

Force = 25N

Distance = 4m

Time = 5secs

To find the workdone;

Workdone = force * distance

Substituting into the equation, we have;

Workdone = 25*4

Workdone = 100 Nm

To find the power consumed;

Power = workdone/time

Substituting into the equation, we have;

Power = 100/4

Power = 25Nm/s

The work done on the box is 100 Nm, and the power is 25 Nm/s.

In a paragraph of no less than five complete sentences, explain how the bubble gum experiment demonstrates the Law of Conservati
Marianna [84]

Answer:

The bubble gum experiment demonstrates the law of conservation of mass in that even though the bubble gum has lost mass, this loss in mass is not because some matter present in the gum has been destroyed, but it has changed  form and has been removed from the gum.

Explanation:

In this science experiment, students investigate whether or not chewing gum should be considered eating. During the process of chewing the gum, the gum loses mass. The experiment is used to demonstrate the law of conservation of mass which states that matter can neither be created nor destroyed but may change from one form to another.

The loss in mass of the gum is due to the fact that the sugar present in the gum has changed form and has been removed from the gum. During the process of chewing the gum, the sugar in solid form present in the gum is dissolved in the saliva found in the mouth. The dissolved sugar is then swallowed and passes into the digestive tract for digestion. This shows that even though the bubble gum has lost mass, this loss in mass is not because some matter present in the gum has been destroyed, but it has changed  form and has been removed from the gum, This demonstrates the law of conservation of mass.

An antiproton is identical to a proton except it has the opposite charge, −e. To study antiprotons, they must be confined in a
Zigmanuir [339]

Answer:

Explanation:

We know that, the force responsible for circulating in circular path is the centripetal force given by the force on charged particle due to magnetic field.

Here the charge is antiproton is

p = -1.6 * 10⁻¹⁹C

the speed of proton is given by 1.5 * 10 ⁴ m/s

the magnetic field is B = 4.5 * 10⁻³T

we have force due to magnetic field is equal to centripetal force

Bqv = mv² / r

Bq = mv / r

r = \frac{mv}{Bq} \\\\r=\frac{mv}{Bq} \\\\r=\frac{1.67 \times 10^-^2^7\times 1.5 \times 10^4}{4.5 \times 10^-^3\times 11.6\times 10^-^1^9} \\\\r=347.9\times 10^-^4\\\\r=3.479cm

The diameter d of the vacuum chamber have to allow these antiprotons to circulate without touching the walls is

d = 2r

d = 2 * 3.479

d = 6.958

d ≅ 7cm
