A horse shoe magnet is placed on a mass balance such that a uniform magnetic field of magnitude B runs between it from North to

BARSIC [14]

Answer:

(a) Measured change in mass (Δm) = BVL/Rg

(b) Total measured mass M' = M - BVL/Rg

Explanation:

Current (I) across is coil is given by the formula;

I = V/R ------------------------1

The magnetic force is given by the formula;

Fb = B*I*L -------------------2

Putting equation 1 into equation 2, we have;

Fb = B*V*L/R -------------------3

Change in mass (Δm) is given as:

Δm = Fb/g -----------------------4

Putting equation 3 into equation 4, we have;

Δm = BVL/Rg

Therefore, change in mass (Δm) = BVL/Rg

2. Since B runs from North to South and current running from East to West, then the magnetic force is directed upward.

Therefore,

Total measure mass M' = M - BVL/Rg

When two point charges are a distance d part, the electric force that each one feels from the other has magnitude F. In order to

Contact [7]

Answer:

Because the force is inversely proportional to the square of the distance

Explanation:

The magnitude of the electrostatic force between two charged particles is given by

$F=k\frac{q_1 q_2}{d^2}$

where

k is the Coulomb's constant

q1, q2 are the magnitudes of the two charges

d is the distance between the two charges

We observe that the magnitude of the force is inversely proportional to the square of the distance.

Therefore, when the distance changes to

$d'=\frac{d}{\sqrt{2}}$

The force will double:

$F'=k\frac{q_1 q_2}{(d/\sqrt{2})^2}=2(k\frac{q_1 q_2}{d^2})=2F$

When you hold your hands at your sides, you may have noticed that the veins sometimes bulge--the height difference between your

hodyreva [135]

To solve this problem it is necessary to use the concepts related to pressure and pressure, absolute and atmospheric.

Average arterial pressure in the hands,

$P = 100mmHg+ h*\rho_{blood}g$

Where,

P = Pressure

h = height (at this case the length of the arm)

Replacing with our values

$P = 100mm(Hg)+(600mm)(\frac{\rho_{blood}}{\rho_{mercury}})(Hg)$

$P = 100mmHg+600*\frac{1060}{13600}mmHg$

$P = 100mmHg+46.765mmHg$

$P = 146.765mmHg$

Where,

$\rho_{blood} = 1060Kg/m^3$

$\rho_{mercury}=13600Kg/m^3$

Therefore the pressure is 146.765mmHg
