Answer:
The temperature is 2584.5 K
Explanation:
Given:
Activation energy

Preexponential

Diffusion flux

Thickness of plate
m
Concentration of carbon at two faces

From the formula of temperature in terms of diffusion flux,

Where
8.314
( gas constant )
Put the values and find the temperature,

K
Therefore, the temperature is 2584.5 K
C. since the the heat from the heater is going to the child in <u>waves</u>, it’s<u> radiating </u>
Answer:
6.46393559312 m/s²
Explanation:
Time taken to cover 56 m

Distance covered in 0.42 seconds

From equation of linear motion


The minimum acceleration is 6.46393559312 m/s²
