Answer:
The specific gravity of kerosene is 0.82
Step-by-step explanation:
Let
x -----> the weight in grams of a cubic centimeter of Kerosene
y ----> the weight in grams of a cubic centimeter of water
z ---> the specific gravity of a substance
so
we have
substitute the values
I prefer D.
It's clear that Kevin took (1/4)x.
Keith took (1/4)x -> kevin's amount
* 2 -> twice.
-1 -> 1 less.
So Kevin + Keith = (1/4)x + (1/4)x * 2 - 1 = (3/4)x - 1.
Answer:
E = 216 joules
Step-by-step explanation:
The given equation is
E = 
............(i)
Here
m = 3 kg
v = 12 m/s
Putting the given values in equation (i)
E = 
E = 
E = 
E = 216 kg m² /s²
or
E = 216 joules
