Answer:

Figure 1: Downward arrow

Figure 2: Downward arrow

Figure 3: Upward arrow on the rod.

Explanation:

The initial force which is applied for a machine to begin work is known as an input force. Machines are designed such that input force increases so that output force increases. Mechanical advantage determines the quality of machine. It is the ratio of output force to the input force.

<u>In figure 1, input force is applied in downward direction so the lever lifts up the barrel at the other end. </u>

<u>In figure 2, input force is applied downwards so that rope is pulled down and at the other end, the load is lifted upwards. </u>

<u>In figure 3, Input force lifts is applied in upward direction to lift the rod which drives the wheel. </u>

HURRY Which change is an example of transforming potential energy to kinetic energy
Jet001 [13]

Answer:

C.  changing nuclear energy to radiant energy

Explanation:

Nuclear energy takes atoms in their potential state, split them (fission) or fuse them (fusion)  creating chain reactions of radiant energy.  Most nuclear electrical power plants use fission, radiant energy heats water making steam to spin turbines.

Or think of the atom bomb.  Definitely potential energy until the fuse starts detonation and chain reactions.  The radiant kinetic energy and shock waves were horrendous.

oscillating spring mass systems can be used to experimentally determine an unknown mass without using a mass balance. a student
puteri [66]

Answer:

Mass, m = 6.18 kg

Explanation:

Given the following data;

Frequency, F = 10 Hz

Spring constant, k = 250 N/m

We know that pie, π = 22/7

To find the mass, we would use the following formula;

F = 1/2π√(k/m)

Where;

F is the frequency of oscillation.

k is the spring constant.

m is the mass of the spring.

Substituting into the formula, we have;

10 = 1/2 * 22/7 * √250/m

10 = 22/14 * √250/m

Cross-multiplying, we have;

140 = 22 * √250/m

Dividing both sides by 22, we have;

140/22 = √250/m

6.36 = √250/m

Taking the square of both sides, we have;

6.36² = (√250/m)²

40.45 = 250/m

Cross-multiplying, we have;

40.45m = 250

Mass, m = 250/40.45

Mass, m = 6.18 kg

Why does magma rise from depth to the surface of the earth?
Viefleur [7K]

Answer

Magma is less dense compared to the surrounding rock.

the overlying rock creates pressure which forces the magma to be directed upward.

Explanation:

at high temperatures the magma is liquid form with the high energy which causes the formation of bonds and the pressure build up creates the increase  channeling of the liquid.as the temperature decreases the magma moves into the surface
