Given:
altitude, x = 1 mile
speed, v = 560 mi/h
distance from the station, x = 4 mi
Solution:
To find the rate,
Now, from the right angle triangle in fig 1.
Applying pythagoras theorem:
differentiating the above eqn w.r.t 't' :
(1)
Now, putting values in eqn (1):
The rate at which distance from plane to station is increasing is:
25Wwwwwwwww has a greater resists
Answer:
power is the rate at which energy is transferred or converted
the unit of power is Watts
Answer:
107 kJ
Explanation:
12.00 kg * 913 J /kg-C * (118-20)°C ( I corrected spec heat units)
( a C degree change is the same as a kelvin change)
= 1 073 688 J = 107 kJ ( three sig digits)
FALSE!!! exercise is great for all systems!!
