Answer:

B) 20 A

Explanation:

VOM full form is Volt Ohm milliammeter. It indicates that voltage, resistance and the current can be measured using this device. When the variations are very rapid , analog VOM is used instead of a digital VOM.

Using this current ( both A C and DC) can be measured in amperes.

Though the accuracy given by digital devices are more accurate, to identify changes in the circuit being tested and for trouble shooting, analog meters are more preferred.

How much work is done lifting a 12-m chain that is initially coiled on the ground and has a density 2 kg/m so that its top end i
Misha Larkins [42]

Answer:

2587.2 J.

Explanation:

From potential energy,

The work done to lift the chain = potential energy of the chain.

W = mgh............... Equation 1

Where W = work done to lift the chain, m = mass of the chain, g = acceleration due to gravity of the chain, h = height of the chain.

But,

m = m'd............... Equation 2

Where m' = density of the chain, d = length of the chain.

Substitute equation 2 into equation 1

W = m'dgh................ Equation 3

Given: m' = 2 kg/m, d = 12 m, h = 11 m, g = 9.8 m/s²

Substitute into equation 3

W = 2(12)(11)(9.8)

W = 2587.2 J.

Which statement is true of a piece of ice at 0°C that is put into a freezer at<br> -18°C?
butalik [34]

The statement which is true about a piece of ice at 0°C which is put into a freezer at -18°C is it having the temperature of the freezer.

<h3>What is Temperature?</h3>

This is referred to the degree of hotness or coldness of a body and the unit is Celsius or Kelvin.

The ice at 0°C will experience a change in temperature of the freezer when put in it in this scenario.

In the lab, you submerge 100 g of 40°C nails in 200 g of 20°C water. (The specific heat of iron is 0.12 cal/g # °C.) Equate the
Deffense [45]

Answer:

Final temperature of the mixture becomes

T = 21.13^oC

Explanation:

Here we know that heat given by the nail is equal to the heat absorbed by water

So here we know that heat to change the temperature is given as

Q = ms\Delta T

so by equating the heat we have

m_{iron}s_{iron}\Delta T = m_{water}s_{water}\Delta T

now we have

100 (0.12) (40 - T) = 200 (1) (T - 20)

4.8 - 0.12 T = 2T - 40

44.8 = 2.12 T

T = 21.13^oC
