AMA is actual mechanical advantage in where it would compare the force in as well as out in using actual measurements in the real life or with friction while in IMA which is the ideal mechanical advantage no friction then is needed. The answer then is a. the value of IMA is larger than AMA.

What describes why ocean currents are considered convection currents
ratelena [41]

Convection occurs because the oceanic waters heat up becoming less dense. This water moves above the cooler water, and give off its heat to the surrounding environment. As it cools, it begins to sink, and the process begins again.

At 19°C, a rod is exactly 19.11 cm long on a steel ruler. Both the rod and the ruler are placed in an oven at 280°C, where the r
Ratling [72]

Answer:

\alpha = 4.12 \times 10^{-5} per Degree C

Explanation:

As we know that when we increase the temperature of the rod and the ruler then in that case there will be change in the length of the both.

Due to this the ruler measurement is different from actual length of the rod

So by thermal expansion we know that

L = L_o(1 +\alpha \Delta T)

L = 19.11 (1 + \alpha(280 - 19))

L = 19.11(1 + 261\alpha)

Now for length of unit division of steel scale

1 unit = 1( 1 + \alpha_s \Delta T)

1 unit = (1 + (11 \times 10^{-6})(280 - 19))

1 unit = 1.0029

now the measured length from the scale is given as

L_{measured} = \frac{L}{1.0029}

L_{measured} = \frac{19.11(1 + 261\alpha)}{1.0029}

19.26 = \frac{19.11(1 + 261\alpha)}{1.0029}

\alpha = 4.12 \times 10^{-5} per Degree C

When released from rest: Potential energy = 100 J and Kinetic Energy would equal?
olga55 [171]

Answer:

0J

Explanation:

The kinetic energy would be zero. An object just released from rest will have no kinetic energy but the potential energy will be maximum.

Kinetic energy is the energy due to the motion of a body

Potential energy is the energy due to the position of a body.

  • The kinetic energy at the start will therefore be zero
  • All the energy is stored as potential energy.

Therefore, the kinetic energy is zero
