Answer:
It takes 534.54 watts
Step-by-step explanation:
Given :
Mass of the book = 30kg
Distance = 10m
Time = 5.5 sec
To Find:
How much power did it take = ?
Solution:
Step 1: calculate the work done
Work done = 
where
m = mass
a = acceleration due to gravity
d = distance
Substituting the values,
Work done = 
=> 2940 Nm
Step 2: calculate the Power
We know that

Substituting the values,

Power = 534.54 watts
Answer:
B
Step-by-step explanation:
Though it is not obvious, the c belongs in the numberator, not the denominator.
So C and D are both wrong.
9: 3 * 3
3: 3
4:2 * 2
Lowest common denominator = 2 * 2 * 3 * 3
Lowest common denominator = 36
B
it was fine, thanks for asking. how was your day?
thanks for the points btw :)
Answer:
9
Step-by-step explanation:
5*23
So there are 8 students, therefore each student gets 1/8 of
the cake.
Since only 3/4 of a cake is available, they will each get
1/8 of 3/4.
We can find this by
multiplying 1/8 and 3/4.
To get the answer, we multiply the numerators together and
the denominators together which gives us:
(1*3)/(8*4) = 3 / 32 = 0.09375
So each student only get 3 / 32 of the cake.
