Answer:
Oblique surface
Explanation:
Surfaces or lines situated at an angle in relation to all the main projection planes are oblique. An oblique surface never appears in any of the main perspectives as a line or true size area. It's Tipped to all main projection planes. doesn't quite appear on the edge of every standard view. doesn't quite show up in any view in true size.it has always been foreshortened.
Answer:
P = 22 watts
Explanation:
Given that,
The output power of the generator = 2 a
The output potential difference = 11 V
We need to find the output power of the generator. The formula for the output power is given by :
So, the output power of the generator is equal to 22 Watts.
Answer:
179 degree
Explanation:
Solid copper will lose heat to warm up and melt ice . Since all the ice has not melted so final temperature of mixture will be zero.
heat gained by ice to reach temperature of zero degree
= mass of ice x specific heat of ice x rise of temp
= 2 x 2093 x 16 = 66976 J
Heat gained to melt 1.1. kg of ice
mass x latent heat of ice
1.1 x 334000
= 367400
total heat
= 367400 + 66976
=434376
Heat lost by copper
= 6.3 x 385 x T
where 385 is specific heat of copper and T is initial temperature
heat lost = heat gained
6.3 x 385 T = 434376
T = 434376 / (6.3 x 385)
= 179 degree .
A: Some physical properties change, but the substance keeps its identity.
