When gases, liquids, or solids are in contact with a moving object, the flow of _____ occurs due to frictional forces.

The answer is HEAT

This is becuase when objects flow against friction energy is rubbed with friction causing surfaces to heat from the molecules rubbing.

Notice that in each conversion factor the numerator equals the denominator when units are taken into account. A common error in

navik [9.2K]

Answer:

he factor for the temporal part 1.296 107 s² = h²

m / s² = 12960 km / h²

Explanation:

This is a unit conversion exercise.

In the unit conversion, the size of the object is not changed, only the value with respect to which it is measured is changed, for this reason in the conversion the amount that is in parentheses must be worth one.

In this case, it is requested to convert a measure km/h²

Unfortunately, it is not clearly indicated what measure it is, but the most used unit in physics is m / s² , which is a measure of acceleration. Let's cut this down

the factor for the distance is 1000 m = 1 km

the factor for time is 3600 s = 1 h

let's make the conversion

m / s² (1km / 1000 m) (3600 s / 1h)²

note that as time is squared the conversion factor is also squared

m / s² = 12960 km / h²

the factor for the temporal part 1.29 107 s² = h²

Which wave characteristics is defined as the number of cycles of a periodic wave occurring per unit time?

Assoli18 [71]

<h3><u>Answer;</u></h3>

Frequency

<h3><u>Explanation;</u></h3>

<em><u>Waves are disturbances that travel through a material medium. There are several characteristics of waves, which includes; wavelength, frequency, period and amplitude. </u></em>
Amplitude is the maximum displacement of wave particles, or simply the height of the wave, measured in meters.
Wavelength is the distance between adjacent crests or troughs in a transverse wave or between two successive rarefaction or compressions in a longitudinal wave, measured in meters.
Period is the time it takes for one complete wave to pass a given point, measured in seconds.
<em><u>Frequency is the number of complete waves or cycles that pass a point in one second, measured is inverse seconds, or Hertz (Hz).</u></em>

Joe the house painter stands on a uniform oak board weighing 600 N and held up by vertical ropes at each end. Joe has been dieti

Mamont248 [21]

Answer

given,

weight of the oak board = 600 N

Weight of Joe = 844 N

length of board = 4 m

Joe is standing at 1 m from left side

vertical wire is supporting at the end.

Assuming the system is in equilibrium

T₁ and T₂ be the tension at the ends of the wire

equating all the vertical force

T₁ + T₂ = 600 + 844

T₁ + T₂ = 1444...........(1)

taking moment about T₂

T₁ x 4 - 844 x 3 - 600 x 2 = 0

T₁ x 4 = 3732

T₁ = 933 N

from equation (1)

T₂ = 1444 - 933

T₂ = 511 N
