Answer:
-------1
Explanation:
beacuse that is what i know
The number of orders that one can see the entire visible speed is 5 orders.
<h3>How to calculate the orders?</h3>
From the information given, it should be noted that the grating spacing will be:
d = (1.00 × 10^-4) / 250
d = 4000nm
Therefore, the number of times that are needed to complete the order will be the same as the number of orders which the long wavelength time will be visible. This will be:
= (4000 × sin 90°)/700
= 5.71
Therefore, the maximum orders will be 5.

Answer:
answer D
Explanation:
circuit breaker is useful when you do something with your domestic electric circuit..
As we know that kinetic energy is given as
Here we can find the initial speed of puck A by momentum conservation
now here we will have initial kinetic energy of the mass is given as
now loss of energy is given as
