Answer:

<em>Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. ... Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.</em>

Answer:

heat, energy that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder. example: stove

Question 3 (5 points)

Elan Coil [88]

True: when there is an angle between force and displacement, $W=Fd cos \theta$

Explanation:

The work done by a force when pushing/pulling an object is given by the equation

$W=Fd cos \theta$

where

F is the magnitude of the force

d is the displacement of the object

$\theta$ is the angle between the direction of the force and of the displacement

We have two extreme cases:

- When the force is parallel to the displacement, then $\theta=0^{\circ}$ and $cos \theta = 1$ , so the work done is maximum and simply becomes

$W=Fd$

- When the force is perpendicular to the displacement, then $\theta=90^{\circ}$ and $cos \theta =0$ , so the work done is zero.

What is the wavelength of an electromagnetic wave that travels at 3 10 m/s and has a frequency of 60 mhz? (1 mhz = 1,000,000 hz)

Dahasolnce [82]

V = 310 m/s
f = 60 MHz = 60 × 10^6 Hz
v = xf
x = v/f
x = 310/(60 × 10^6) m
x = 5.166667 × 10^(−6) m
