What is the transfer of energy in the form of rays or waves.?

2 answers:

7 0

Heat energy is transferred through liquids and gases by movement of up-and-down molecules called convection currents. Examples: Hot air balloon, boiling water and weather currents. Heat energy is transferred in the form of invisible waves called INFRARED RADIATION.

Answer:

C. a clamp light with a 150-W lightbulb placed 25 cm from the radiometer

Explanation:

because the temperature has to be set, meaning it can't change, and it should be a different distance away than the first one.

Hope this helps! Stay safe!

Two children stretch a jump rope between them and send wave pulses back and forth on it. The rope is 2.6 m long, its mass is 0.5

Irina-Kira [14]

Answer:

15.13 m/s

Explanation:

The wave speed of the stretched rope can be calculated using the following formula

$v = \sqrt{\frac{F_T}{\mu}}$

where $F_T = 44N$ is the tension on the rope and $\mu = m/L = 0.5 / 2.6 = 0.1923 kg/m$ is the density of the rope per unit length

$v = \sqrt{\frac{44}{0.1923}} = \sqrt{228.8} = 15.13 m/s$

Consider three resistors with unequal resistances connected in series to a battery. Which of the following statements are true?

Ivenika [448]

<h2>Answer: The second Statement </h2>

<h2>The algebraic sum of the currents flowing through each of the three resistors is equal to the current through the battery. </h2><h2 />

In a series circuit, the value of the equivalent resistance $R_E$ is equal to the sum of the values of each of them:

$R_ {E}=R_{1}+R_ {2}+R_ {3}$

Where:

<h2>The equivalent resistance of the combination of resistors is greater than the resistance of any one of three resistors. </h2>

In this case the current $I$ flowing through the resistors is the same in each one. This is because the current flowing through the circuit only has one way to go, so the current intensity is the same throughout the circuit.

Therefore:

<h2>The current flowing through each of the resistors is the same and is equal to the current through the battery. </h2><h2>The algebraic sum of the voltages across the three resistors is equal to the voltage across the battery. </h2>

The battery provides a voltage $V_T$ that is the sum of the different voltages at the ends of the resistors:
