1. Power.
Power is the rate of energy transfer or the rate at which work is done.
2. watt
Power=energy or work done/time=1 J/1s=1 watt (w)
3. Current times the voltage
E=QV
Q=I times t
E=VIt
p=E/t
p=VIt/t
p=VI
4.200 watts
p=VI=40 x 5=200 W
5. Amount of power available is significantly greater.
p=VI
When V increases, I must go down at the same time so that p doesn’t increase.
Since I is decreased, the power losses due to joule’s heating effect is decreased. The equation representing the energy loss for joule’s heating effect is:
E=I^2Rt
As I is decreased, the energy loss also decreases. Power=energy transferred/time and so as the energy loss due to Joule’s heating effect is decreased, the power loss is also decreased.
Answer:
a)F=(208 i+156 j) kN
b)F+W=219 kN
Explanation:
Solution:
To determine the components of F
F=(260 kN).()
=(208 i+156 j) kN
F=(208 i+156 j) kN
b)weight W expressed in component and add into the
Force F.
W=-(8800 kg).(9.81 m/s^2)j
F+W=(208 i+[156-86.3]j) kN
F+W=
=219 kN
F+W=219 kN
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: 54.55 m/s
Explanation:
Distance = 300 m
Time = 5.5 s
Average Speed = Total Distance/Total Time
= 300/5.5
= <u>54.55 m/s</u>
Hope this helped..
<h2>Answer:</h2>
False:
<h2>Explanation:</h2>
Jet streams are like rivers of wind high above in the atmosphere which have a huge influence on climate because they can push air masses and affect weather patterns. Jet streams travel in the tropopause which is the boundary between the turbulent troposphere and the calm, cold stratosphere. So we can say that jet streams lie in stratosphere and not in mesosphere.
