Answer: 2
The hands need to be in direct contact with the flames to have conduction
Explanation:
A fire spreads by transferring heat energy in three ways: Radiation, Convection, and Conduction. Radiation by emitting energy in rays or waves. Heat moves through space as energy waves by conduction. As the fire front gets closer, the amount of radiant heat received is increased.
Heat energy in the form of electromagnetic radiation moves away from a hot object in all directions. Radiant heat is particularly important to fire development in a compartment in that it serves as one of the primary mechanisms for fire spread within the compartment.
Answer:
The intensity is
Explanation:
From the question we are told
The frequency of the electromagnetic wave is
The peak value of the electric field is
Generally the intensity of this wave is mathematically represented as
Where c is the speed of light with value
is the permittivity of free space with value
Substituting values into equation for intensity
Converting to we divide by 10,000
Answer:
"Both students are correct. When light is traveling through small openings, solids, liquids, gases, or a vacuum, it behaves like a wave. When it interacts with matter, it acts like a stream of particles."
Explanation:
just got it right
There are two particular cases, the first is when Object A is attracted to the neutral wall. This would indicate that the object is not neutral, as there is an attraction.
At the same time we know that Object A is attracted to an object B. And therefore, the load of A must be opposite to that of B. Remember that opposite charges attract each other. If the charge of object B is positive, then the charge of object A will be negative.
Option B is correct: It has a negative charge.
