100-25=75
speed=distance/time so time=distance/speed
75/15 =5 seconds
Answer: displacement
Explanation:
According to the definition of displacement it is the shortest distance between two points.
I think it’s current= A / C
Work done = mgh where h varies from 0 (at the bottom of the pool) to 5 ft (at the sides of the pool).
m= density*volume = 62.5*pi*24^2*d/4 = 9000πd lbs
h = 5-d (the particles at the top of the pool require less work as required to those at the bottom).
Then,
WD (E) = 9000πd*9.81*(5-d) = 88290πd(5-d) = 441450πd-88290πd^2
Integrating from 0-4 with respect to depth of pool, d
Total E = {441450π*d^2/2 - 88290π*d^3/} for d between 0 and 4 ft
E=220725π*d^2 -29430π*d^3
Substituting for d=0 ft and d=4 ft;
= {220725*π*4^2-29430π*4^3} - {220725π*0^2-29430*pi*2*0^3)
=5177596.021 J= 5.17 MJ
Answer:
1.029
Explanation:
1.0090 can also be looked at as "1.009"
0.02 can also be looked at as "0.020"
I think of it as 20+9 which is 29. There for your answer should be 1.029. There are no measurement rules applying to this equation since they are both in centimeters. So you don't have to convert anything.
