Answer:
Infrared Wavelength
Explanation:
It is because the most long range wavelength i n this case will be the infrared wavelength that has a heating effect on bodies when exposed for a longer period of times. Similarly, the visible wavelength of light is also involved. The defective parts in the fireplace will allow the escape of these infrared wavelength radiations. This heating effect can cause fire near the fire place where the defective fireplace is placed without modifications.
Answer: - 452.088joule
Explanation:
Given the following :
Mass of water = 12g
Change in temperature(Dt) = (11 - 20)°C = - 9°C
Specific heats capacity of water(c) = 4.186j/g°C
Q = mcDt
Where Q = quantity of heat
Q = 12g × 4.186j/g°C × - 9°C
Q = - 452.088joule
Otal energy= PEmax on the spring = KEmax of the oject
<span>Total Energy= KE+PE at v or x not maximum. </span>
<span>Using the second line </span>
<span>E= 3/4 E + PE </span>
<span>PE = 1/4 E </span>
<span>PEmax =E = 1/2 kA^2 </span>
<span>PE=E/4 = (1/2)kA^2 / 4= kA^2/8
</span>

To operate a mixer circuit , Anne should use a (motor, buzzer, bulb, or battery) to transfer electric energy into motion. She should also use a (switch, resistor, buzzer, or bulb) to start and stop the flow of current.
An electric-powered circuit consists of a device that gives energy to the charged particles constituting the modern-day, consisting of a battery or a generator; devices that use cutting-edge, including lamps, electric cars, or computer systems; and the connecting wires or transmission traces.
An electrical circuit is an interconnection of electrical components or a version of such an interconnection, consisting of electrical elements. an electrical circuit is a network along with a closed loop, giving a go-back direction for the cutting-edge.
An electrical circuit consists of a source of electrical strength, two wires that can convey electric power present day, and a mild bulb. One stop of both the wires is hooked up to the terminal of a mobile at the same time as their free ends are related to the light bulb. the electric circuit is damaged while the bulb is switched off.
