Answer:
Explanation:
BMI= weight/(height × height) ; weight in kilogram and height in metter
= 58kg / (1.61m × 1.61m )
= (58/ 2.5921) kg/
= 22.375 kg/
≈ 22.4 kg/
To solve this problem we need to use the emf equation, that is,
Where E is the induced emf
I the current in the first coil
M the mutual inductance
Solving for a)
Solving for b) we need the FLux through each turn, that is
Where N is the number of turns in the second coil
Answer:
Explanation:
velocity of the Escalators is given as 6 ft/s
now we know that Jane steps on parallel escalator after t = 5 s
so distance moved by John in same time interval is given as
now John and Jane will move towards each other with relative speed
Then will approach towards each other with this relative speed and meet after t = 15 s
so the distance moved by them
so total length of the escalators is given as
P = Momentum
M = Mass
t = time
v = velocity (speed)
J= Impulse
1.)
F = 100N
t = 5s
Change in momentum(P) = Ft
I see that this is not one of your equations but your equations do not work with this problem.
P = Ft
P = (100)(5)
P = 500 Ns
2.)
See if you can get this one by yourself from what I did on the last problem.
3.)
P = 25 kgm/s
M = 2.0 kg
So, you are looking for velocity (speed). Look for the equation that has momentum, mass and velocity.
Use the equation P = mv
25 = 2(v)
25 = 2v
25/ 2 = 2v/2
12.5 m/s = v
4.) Do the same for number 4.
P = 12 kgm/s
M = 1kg
P = mv
12 = 1v
12/1 = 1v/1
12 m/s = v
6.)
P = 100 kgm/s
V= 7.0m/s
P= mv
100 = m7.0
100/7 = 7.0m/7
14.28 kg = m
Try page 2 by yourself and message me or comment if you need more help. Just identify the variable you have and what you need to find and put them in an equation that fits. You can do this!!!!
