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.
The speed of a satellite in a circular orbit around the Earth is 4,188 m/s.
<h3>Speed of the satellite</h3>
The speed of the satellite is calculated as follows;
v = √GM/r
where;
- M is mass of Earth
- r is radius of satellite
v = √[(6.67 x 10⁻¹¹ x 5.98 x 10²⁴) / (3.57 x 6.37 x 10⁶)]
v = 4,188 m/s
Thus, the speed of a satellite in a circular orbit around the Earth is 4,188 m/s.

In both graphs, speed will be measured in meters/second.
In graph A, the object travelled a distance of 40 meters in 4 seconds
In graph B, the object is at rest for 5 seconds.
These are the correct answers
Answer:
due to the heating of particles
