I don’t know how air would be an insulator so I’m guessing that one isn’t
Answer:
a) Y component of the vector =15.54 m
b) Vector magnitude = 21.6 m
Explanation:
The given vector makes 44 degree angle with Y axis, as given. This is same as 90 -44 = 46 degrees with the horizontal or X axis.
b) X component of the given vector =
= A cos 46 =15
⇒ A = 15/cos 16 = 21.6 m = Total vector magnitude.
a) Y component of the vector = 21.6 sin 46 = 15.54 m
b) A = 21.6 m
Answer:
100 mph
Explanation:
Average speed = distance / time
v = 250 mi / 2.5 hr
v = 100 mi/hr
Answer:
(a) 17450.8 J (B) 1.239 sec
Explanation:
We have given power output =8 KW
Heat expelled = 10994 j
Efficiency =37% = 0.37
(A) We know that efficiency 

Heat input =17450.8 J
(B) Work done by the engine is = 17450.8-10994=6456.8 j
Power output is given by 8 KW =8000 W
So time for each cycle is
