Answer:
Explanation:
You didn't last any of the variables. You have to list the variables to tell which are which.
The steps in the heating of a metal seat in a park are:
Step 1: Heat travels from the sun to Earth
Step 2: Heat travels through atmosphere to the top of the seat
Step 3: Heat from the top of the seat travels through the seat to the lower parts of the seat.
-- Heat is transferred by radiation in Step 1 and Step 2. <em>(B)</em>
-- From the top of the seat to the bottom, heat is transferred by conduction.
There's no convection happening anywhere in the park-hot-seat scenario.
Answer:
Explanation:
Given that,
Lightning flashes one mile (1609 m) away from you.
We need to find the time it take the light to travel that distance. Let the time be t. We know that,
speed = distance/time
So, the required time is 
Yes It is all metal is a good heat conductor
Answer:
6.62607004 x 10^(-34)m²kg/s
Explanation:
This is the constant that shows the value of energy of a photon in relation to it's frequency.
