Falling, you can also suffer from severe radiation sickness and be crushed.
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 voltage will be multiplied by 4...
The element is a resistor, so some of the electrical energy flowing through the heating element is converted to thermal energy.
Let v = the launch velocity.
Because the launch angle is 40° (with the horizontal), the initial vertical velocity is
v* sin(40°) = 0.6428v m/s.
Assume g = 9.8 m/s² and ignore air resistance.
At maximum height, the vertical velocity is zero.
Because the maximum vertical height is 10 m, therefore
(0.6428v m/s)² - 2*(9.8 m/s²)(10 m) = 0
0.4132v² = 196
v = 21.78 m/s
Answer: 21.8 m/s (nearest tenth)
