Answer:
The magnetic field is lowest for largest distance and highest when distance is least.
Explanation:
The magnitude of magnetic field strength at a distance 'r' from a long straight wire carrying current 'I' is given as:
Now, as per question, the distance 'r' is varied while keeping the current constant in the wire.
As seen from the above formula, the magnitude of magnetic field strength for a constant current varies inversely with the distance 'r'. This means that, as the value of 'r' increases, the magnitude of magnetic field strength decreases and vice-versa.
Therefore, the magnitude of magnetic field strength is maximum when the distance 'r' is least and the magnetic field is minimum for the largest distance.
Example:
If 
are the magnitudes of magnetic field strengths for distances 
respectively such that 
. Now, as per the explanation above, the order of magnitudes of magnetic field strength is:
Their final velocity is 0.48 m/s.
We can use conservation of momentum to calculate the magnitude of the final velocity.
Momentum before collision is equal to the momentum after collision
m1v1+m2v2=(m1+m2)v
here, v is final velocity , assuming right side velocity as positive, and left side velocity as negative.
14*(-1.1)+18*(0)=(14+18)v
v=-0.48 m/s
Here, negative sign indicates that they both will move in left direction.
An example would be a pot on a stove. The radiation from the source of the heat (the stove) would make the handle hot by conduction from heat through contact.
Another example could be a metal spoon in a hot cup of coffee. The coffee itself is hot, but since the spoon is in the coffee and making contact, part of the spoon will become hot from the radiation of the source of heat (the hot coffee). Thus, conduction.
Answer:
halve the slit separation
Explanation:
As we know that
In YDS experiment, the equation of fringe width is as follows
where,
D denotes the separation in the middle of screen and slits
d denotes the distance in the middle of two slits
And to increase the Δx we have to decrease the d i.e, the distance between the two slits
Hence, the first option is correct
The prokaryotic cells are indeed smaller than the eularyotic cells.
Eukaruotic cell size -10-100um
Prokaryotic cell size - 1-10 um
