Answer:
1. will blow because the total current in this circuit is 14 A which is greater than 12 A.
Explanation:
According to Kirchoff current law (KCL) which states that the total current flowing in a circuit is equal to the sum of the individual branch current.
If the supply current is greater than the sum of the individual branch current, then the load will collapse or blow off.
In the question given, the total current of the fuse is 12A
Sum of branch currents = current in branch 1 + current in branch 2
= 8A+6A
= 14A
As we can see that the supply current is lower than the sum of the branch current, this will cause the fuse to blow because some of the branch current will be sent back on the fuse and thereby causing the fuse to blow.
The man on the ground in standing position has <u>more</u><u> </u><u>pressure</u><u>.</u> This is because when he stands, only his legs are in contact with the ground. While lying, his body is more in contact with the ground, therefore, he exerts less pressure.
To the point, <u>a</u><u> </u><u>manin</u><u> </u><u>standing</u><u> </u><u>posi</u><u>tion</u><u> </u><u>on</u><u> </u><u>the</u><u> </u><u>gr</u><u>ound</u><u> </u><u>had</u><u> </u><u>more</u><u> </u><u>pre</u><u>ssure</u><u>.</u>
More is the area of contact, less is the pressure efforted.
Thank you...
Answer:
The refractive index of material of prism is 1.06.
Explanation:
Given that,
Angle of prism, A = 40 degrees
Angle of deviation,
We need to find the refractive index of material of prism. We know that the relation between angle of deviation, prism angle and the refractive index is given by :
is the refractive index of material of prism
So, the refractive index of material of prism is 1.06. Hence, this is the required solution.

The factor by which the shutter speed is increased is
Exposure time will be increased by
The proper shutter speed is given by
The proper shutter speed is
<em>The displacement of an object during a specific unit of time: </em>Velocity (the direction is part of displacement.)
<em>How fast or slow an object is moving and in what direction: </em>Velocity (speed & direction)
<em>How fast or slow an object is moving: </em>Speed (no direction)
<em>A cheetah running 97 km/h: </em>Speed (no direction)
<em>A train traveling 45 m/s north: </em>Velocity (speed & direction)
