<span> vernier scale because is a part of vernier calipers.rest of them are parts of other measuring instruments like dial guage, screw guage etc</span>
Answer:
abraham maslow
Explanation:
I'm surprised i remembered that. I hope that's correct, good luck on whatever you're doing :)
The answer is letter C. 1.2 10^-11 N up
Solution:
F= Bqvsin(theta)
theta = sin 90 = 1
F= 1.4 T * 1.6x10^-19 * 5.2x10^7 ms^-1
F= 1.16 x 10^-11 N
Then the direction is upward.
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
