What is the mass, in grams, of a pure iron cube that has a volume of 3.70cm cubed?
Arlecino [84]
To determine the amount in grams of the iron, we need data on the density of iron. From literature, it has a value of <span>p=7.9 g/cm3. We simply multiply the volume to the density. We do as follows:

mass = 3.70 (7.9) = 29.23 g Fe

Hope this answers the question. Have a nice day.</span>

What is the difference between mutual flux, leakage flux and magnetizing flux<br> ​
Lemur [1.5K]

In simple words, flux can be stated as the rate of flow of a fluid, radiant energy, or particles across a given area.

<u>Explanation:</u>

<u>Mutual Flux:</u>

  • The magnetic lines present in among two magnets or solenoid is mutual flux.
  • These are the lines in which the attraction and repulsion happens.
  • The SI unit of mutual flux is the Henry

<u>Leakage Flux:</u>

  • In simple words, it can be stated as  the magnetic flux which does not follow the specially designed way in a magnetic circuit.
  • Leakage flux in the induction motor takes spot due to current runs through the essence of the induction motor.
  • The SI unit of Leakage flux is the Weber

<u>Magnetizing flux</u>

  • Magnetic flux is an analysis of the entire magnetic field which moves in a given field
  • In simple words can be defined as the Magnetic flux is what generates the field around a magnetic material.
  • The SI unit of magnetic flux is the Weber

While Bob is demonstrating the gravitational force on falling objects to his class, he drops an 1.0 lb bag of feathers from the
BartSMP [9]

In the experiment of free fall bob released a bag of mass 1 lb

so here we can say that initial speed of the bag is Zero

time taken by the bag to free fall is given as

t = 1.5 s

also the acceleration of free fall is given as

a = 9.8 m/s^2

now we will use kinematics equation here for finding the distance of free fall

d = v_i * t + \frac{1}{2} at^2

d = 0 + \frac{1}{2}*9.8* 1.5^2

d = 4.9 * 2.25

d = 11.025 m

so the bag will fall down by total distance of 11.025 m from its initial released position.

A force of 450 N moves a body through 300 cm in the direction of force. Calculate the work
OlgaM077 [116]

Answer:

150J

Explanation:

Formula : <u>Work</u><u> </u><u>done</u>

Force x distance

work done = force x distance

Distance should be measured in meters

300÷100=3m

work done = 450 x 3

=150J

As water rises through the troposphere and cools, it changes from a(n) ————- to a(n) ———— through the process of condensation; w
Hoochie [10]

Answer:

GAS,   LIQUID,    CLOUDS

Explanation:

Water can be in three states: solid, liquid and gas, passing from one to another depending on the pressure and temperature.

In this complementation exercise.

When the water cools down the GAS goes to the LIQUID state, these small drops unite and form the CLOUDS
