Answer:
Option C.
Polarization takes place!
Answer:
1.12 N
Explanation:
Let the masses be m and M and distance be d . Force between them is .28 N .
Applying Newton's law of Gravitation
.28 = G x m M / d²
distance is halved , so distance becomes d /2
Force of attraction = G m M / ( d/2)²
= 4 Gm M / d²
= 4 x .28
= 1.12 N .
Answer:
a) P = 15993.6 N/m²
b) P' = 11062.24 N/m²
Explanation:
Given:
Density of the mercury, ρ = 13.6 × 10³ kg/m³
The blood pressure reading is given as 120 over 83 mm
a) Now,
The pressure (P) due to a fluid is given as:
P = ρgh
where, g is the acceleration due to the gravity
h is the pressure head
The systolic pressure head from the blood pressure reading is , h = 120 mm = 0.12 m
substituting the value in the formula for pressure,
we get
P = 13.6 × 10³ × 9.8 × 0.12
or
P = 15993.6 N/m²
b) The systolic pressure head from the blood pressure reading is , h' = 83 mm = 0.083 m
substituting the value in the formula for pressure,
we get
P' = 13.6 × 10³ × 9.8 × 0.083
or
P' = 11062.24 N/m²
