By V=IR
A: 24=I*20
I = 1.2A
B: 220 = I*250
I = 0.88A
C: 6= I*3
I = 2 A
C,A,B
Answer:
(a)
(b) 5220 j
(c) 1740 watt
(d) 3446.66 watt
Explanation:
We have given mass m = 290 kg
Initial velocity u = 0 m/sec
Final velocity v = 6 m/sec
Time t = 3 sec
From first equation of motion
v = u+at
So
(a) We know that force is given by
F = ma
So force will be
(b) From second equation of motion we know that
We know that work done is given by
W = F s = 580×9 =5220 j
(c) Time is given as t = 3 sec
We know that power is given as
(d) Time t = 1.5 sec
So
Pennsylvania or Texas are large producers of natural gas.
Photosynthesis is a good one you can really explain with pictures
Answer:
Explanation:
If we consider the ideal conditions, the force acting on the bob of the pendulum is only the gravitational force and the tension force in the string, s the pendulum keeps oscillating.
But in general practice, the pendulum stops after some time, it is due to the force of friction due to air and some dissipative forces due to the thread, etc. These force tries to stop the motion of bob and then eventually it stops.
