Well you know the formula is,
Power= Work/Time
So as time increases, Power Decreases, it's an inverse relationship.
Think about it like this, to have more "power" you have to be able to do a lot in a short amount of time, so by spending more time on something, your power decreases.
Answer:
no of revolutions = 56.62 rev
Explanation:
given data
rotates = 1560 rpm
travels distance = 18.5 meters
speed = 40.2 m/s
solution
first we convert here rev/min to rev/sec
rotates = 1560 rpm = 1560 × 0.0167 = 26.052 rev/sec
we get here no of revolutions that is
no of revolutions = spin rotate ÷ time ..........1
here time = distance ÷ speed
time = 18.5 ÷ 40.2
time = 0.4601 s
put value in equation 1 we get
no of revolutions =
no of revolutions = 56.62 rev

Answer:
Explanation:
A. Using
Sinစ= y/ L = 0.013/2.7= 0.00481
စ=0.28°
B.here we use
Alpha= πsinစa/lambda
= π x (0.0351)sin(0.28)/588E-9m
= 9.1*10^-2rad
C.we use
I(စ)/Im= (sin alpha/alpha) ²
So
{= (sin0.091/0.091)²
= 3*10^-4
After conversion from cm³ to ml we get 3mili litres.
<h3>What are fundamental units?</h3>
The SI comprises a coherent system of units of measurement starting with seven base units ,which are the second,metre, kilograms,ampere, kelvin, mole and candela. SI unit is a scientific method of expressing the magnitude or quantities of important natural phenomenon.
When measured an object by the help of ruler I get the value 3cm and when I calculated its volume is 3cm³ . After converting it from cm³ to ml we get 3ml .
