Answer:
Explanation:
We have given number of turns N = 560
Inductance L = 8.9 mH
Current through the coil = 7 mA
Inductance of the coil is given as
Where N is number of turns I is current and is flux
So
Answer:
W=1705.2 J
Explanation:
Given that
mass ,m= 60 kg
Acceleration due to gravity ,g= 9.8 m/s²
Height ,h= 2.9 m
As we know that work done by a force given as
W = F . d
F=force
d=Displacement
W=work done by force
Now by putting the values
F= m g (Acting downward )
d= h (Upward)
W= m g h ( work done against the force)
W= 60 x 9.8 x 2.9 J
W=1705.2 J
Therefore the answer will be 1705.2 J.
The statement about "<span>efficiency compared the output work to the output force" is false. Efficiency can be compared from the input work to the output work.</span>
Answer:
Second Trial satisfy principle of conservation of momentum
Explanation:
Given mass of ball A and ball B
Let mass of ball and
Final velocity of ball
Final velocity of ball
initial velocity of ball
Initial velocity of ball
Momentum after collision
Momentum before collision
Conservation of momentum in a closed system states that, moment before collision should be equal to moment after collision.
Now,
Plugging each trial in this equation we get,
First Trial
momentum before collision moment after collision
Second Trial
moment before collision moment after collision
Third Trial
momentum before collision moment after collision
Fourth Trial
momentum before collision moment after collision
We can see only Trial- 2 shows the conservation of momentum in a closed system.
Answer:
F=ma
therefore A=F/M
