Answer:
The number of turns in the second coil is more than the coil 1.
Explanation:
The magnetic field lines are the imaginary path on which an isolated north pole moves if it is free to do so.
The tangent at any point to the magnetic field line, gives the direction of magnetic field at that point.
More be the crowd ness of magnetic field lines more is the strength of magnetic field.
Here the crowd ness of magnetic field lines is more in figure 2 , so the magnetic filed in figure 2 is more than 1. It shows that the number of turns in the second coil is more than the 1 and also the current in the coil 2 is more than 1 .
Answer:
0.084 kg
Explanation:
I = 0.80 N-s (East wards) = 0.80 i N-s
u = 3.8 m/s = - 3.8 i m/s
v = 5.7 m/s = 5.7 i m/s
Let m be the mass of bat.
I = m (v - u)
0.8 i = m ( 5.7 i + 3.8 i)
0.8 i = m x 9.5 i
m = 0.084 kg
Answer:
Becuase
So then we can conclude that:
And that makes sense since the force needs to accelerate the two masses and just need to accelerate .
So the best option for this case would be:
a. T1 > T2
See explanation below.
Explanation:
For this case we consider the system as shown on the figure attached.
Since the system is connected the acceleration for both masses are equal, that is
From the second Law of Newthon we have that the force applied for the mass is and we know that the force acting on the x axis for the mass 2 is so then we have that
Now when we consider the system of as a whole mass, this system have the same acceleration and on this case we will see that the only force acting on the entire system would be and then by the second law of Newton we have that:
And then if we compare and we see that :
Becuase
So then we can conclude that:
And that makes sense since the force needs to accelerate the two masses and just need to accelerate .
So the best option for this case would be:
a. T1 > T2
Potential energy is proportional to the object's mass, and to the height
to which it's lifted. If the heights are the same, then it depends only on
the mass, and the 4-kg object has more potential energy at that height.
How long it took each one to arrive at that height is a totally irrelevant
consideration.
