We can't tell without more information. We know it will be higher than 40 and lower than 75, but we don't know exactly where it will settle. In order to work that out, we would need to know the volumes of the water and the cube, and WHAT metal the cube is made of.
Answer:
Option (C) is the answer
Explanation:
may be it is possible if that we stand so far
The answer would be 20000
The answer in standard form/scientific notation would be 2 x 10^4
(The exponent is 4 because that's how many digits after the 2 there is)
Answer:
or 
23.4843749996 m
Yes
Explanation:
E = Electric field = 
c = Speed of light = 
m = Mass of proton= 
q = Charge of electron = 
Acceleration is given by

Dividing by g

The acceleration is
or 

The distance is 23.4843749996 m
The gravitational field is very small compared to the electric field so the effects of gravity can be ignored.
