Answer:
Length = 2.92 m
Diameter = 0.11 mm
Explanation:
We have , where:
is the length
We divide the first equation by the second equation to get:
Using this Area, we find the diameter of the wire:
To find the length, we multiply the two equations stated initially:
Answer:
Explanation:
"The thermal energy moving from her coffee to the tongue" represent the heat.
Here coffee is at high temperature while tongue is at low temperature, when Ixchelt tongue make contact with coffee then thermal energy of coffee is absorbed by tongue and tongue gets burned.
As heat always from high Potential to low that is why heat is absorbed by tongue.
Answer:
Subtract the kinetic energy at the bottom from the potential energy loss. The remainder becomes frictional heat.
Potential energy loss:
M g H = 21.7*9.81*3.5 = 745.1 J
Kinetic energy at bottom of slide:
= (1/2) M v^2 = 52.5 J
b is the answer there you go if you need the answer
