Answer:

See the explanation below.

Explanation:

53) Yes, this process is called latent heat transfer, it happens when heat is transferred to a body or a substance, an increase in its energy is observed without presenting an increase in temperature. An example of this can be seen in the evaporation of water.

54) It absorbs energy since heat transfer always occurs from a space of higher temperature to another with lower temperature so as the wax freezes the heat is transferred from the environment to the wax.

55) The water vapor and wet air will be absorbed by the canvas, the heat contained in this water vapor will be absorbed by the canvas in this way decreases the temperature of the water inside the canteen.

56) The process is vaporization. The refrigerant of the air conditioning equipment enters the coil, in the form of liquid, this liquid is at low temperature, so that the room air at a higher temperature, exchanges heat with the refrigerant liquid, the refrigerant liquid changes the phase of liquid to vapor, for when it is completely vaporized this can be sucked by the compressor equipment.

A 5.58 kg object with a speed of 35 m/s strikes a steel plate at an angle of 45.0 degrees with the normal to the plate, and rebo
MAVERICK [17]

Answer:

magnitude of vector is 276.19 kg m/s

Explanation:

The initial momentum is vector of magnitude

5.58 \times 35 = 195.3 (kg m/s)  And driven in a coherent manner with initial vector.

same magnitude is momentum after the impact, but it is oriented perpendicularly to initial momentum vector.

So, you have 2 momentum vector of  specified magnitude perpendicular to one another.

 The contrast between such two vectors is a right angle triangle hypotenuse of 195.3 sides

magnitude of vector is  \sqrt{ 195.3^2 + 195.3^2} = 276.19

Find the length of a microscope having magnifying power 100, if the focal lengths of the objective and eye piece are 2 cm and 5
sp2606 [1]

Answer:

   L = 40 cm

Explanation:

A microscope is an optical instrument built by two lenses in such a way that the image of the first is formed within the distance of the other (eyepiece), so that the latter creates an enlarged virtual image of the object, for which the magnification of the microscope is the same to the multiplication of the magnification of each lens

    M = - L / f₀ (25 cm /f_{e})

where fo and fe are the focal lengths of the objective and eyepiece, 25 cm is the near vision distance and L is the length of the microscope

     L = - M f_{o} f_{e} / 25

let's calculate

     L = - (-100) 2 5/25

      L = 40 cm

Amy uses 20N of force to push a lawn mower 10 meters. How much work does she do? *
babunello [35]

She does 200J .

We know she uses 20N of force and 10m is the distance. We multiply both numbers and we are given our answer of 200J. Hope this was helpful. :)
