What happens if the physics student is standing on ice

1 answer:

7 0

The thing that will happen to the physics student when he's standing on the ice will be entirely depended on his weight and the amount of resistant force that the ice can handle.
If the student's weight is larger than the amount of resistant force, it would be very likely that the ice will break

Lets say that:

Eric is E

Sheena is S

Yael is Y

We know that S+2=Y, E= 1/S and that E+S+Y=52. So, we can insert S+2=Y and E= 1/S into our other equation, which would bring us to (1/2S)+(S+2)+S=52. This is equal to 1/2S+S+2+S=52. We then use algebra to get the answer:

Given:

S+2=Y

E=1/S

E+Y+S=52

Equation:

1/2S+S+2+S=52

1/2S+S+S=52

2.5S=50

S=50/2.5

S=20

And since Yael has 2 more points then Yael then we do 20+2 and get 22.

kifflom [539]

Answer:

Explanation:

Given

Work required $W=1.35\times 10^{-20}\ J$

Work done to eject the sodium ion from interior of the cell is given by the product of charge and Potential difference between inner and outer surface of the cell.

$W=q\times V$

Charge on sodium ion $q=1.6\times 10^{19}\ C$

$V=\frac{W}{q}$

$V=\frac{1.35\times 10^{-20}}{1.6\times 10^{19}}$

$V=0.0718\ V$
