Answer:
Zero
Explanation:
Because using
Deta X= dsinစ x n(lambda)
But we know that for central maxima
n is zero
So after substituting
Deta x = 0
Answer:
Vector Quantity
Explanation:
A Vector quantity is a quantity has both magnitude and direction while scalar quantity has only magnitude.
The time taken for anna to move the box the distance of 9.72 meters is 25.9 seconds. The correct option is c.
<h3>What is force?</h3>
The force is the action of push or pull to move or stop an object.
Anna pushes a box with a force of 8.00 newtons. she generates a power of 3.00 watts.
Force is related to power by the relation
Force = Power / Velocity
Put the values, we get
8 = 3/V
V = 0.375 m/s
Velocity is defined as the ratio of distance and the time taken.
The box is moved by the distance of 9.72 meters. So, time taken is
V = d/t
0.375 = 9.72/t
t =25.9 seconds.
Thus, time taken for anna to move the box the distance of 9.72 meters is 25.9 seconds.

Answer:
The correct answer is options (1) and (4).
Explanation:
Due to the rotation of the earth Coriolis force is generated. As the earth rotates from the west to the east, it changes the pattern of global wind and ocean water movement.
This force allows the ocean surface water to move in the clockwise direction in the northern hemisphere, and anticlockwise in the southern hemisphere.
Thus, the correct answer is options (1) and (4).
