Which force is an attractive force that is affected by the masses of objects?

Suppose a blood vessel's radius is decreased to 87% of its original value by plaque deposits and the body compensates by increas

dexar [7]

Answer:

The pressure difference will increase by the factor of 1.75

Explanation:

For constant flow rate, coefficient of viscosity, length of the vessel and the pressure difference is inversely proportional to the fourth power of the radius of the blood vessel

Apply the principle of Poiseuille’s law.

Q = (P2 - P1)/R

Two long, straight wires are parallel and 20 cm apart. One carries a current of 2.2 A, the other a current of 5.9 A. (a) If the

Leya [2.2K]

Answer: $1.298\times 10^{-5}\ N/m$

Explanation:

Given

Current in the first wire $I_1=2.2\ A$

Current in the second wire $I_2=5.9\ A$

wires are $20\ cm$ apart

Force per unit length between the current-carrying wires is

$\Rightarrow \dfrac{F}{l}=\dfrac{\mu_oI_1I_2}{2\pi r}$

Force exerted by the wires is the same

Put the values

$\Rightarrow \frac{F}{l}=f=\dfrac{4\pi \times 10^{-7}\times 2.2\times 5.9}{2\pi \times 0.2}=1.298\times 10^{-5}\ N/m$

This force will be repulsive in nature as the current is flowing opposite

A small ferryboat is 3.90 m wide and 6.30 m long. when a loaded truck pulls onto it, the boat sinks an additional 5.00 cm into t

Leya [2.2K]

When the truck's weight is added to the boat, the boat sinks 5 cm deeper,
and displaces additional water whose weight is equal to the weight of the
truck.

The volume of the additional displaced water is

(3.9 m) x (6.3 m) x (5.0 cm)

= (3.9 m) x (6.3 m) x (0.05 m) = 1.2285 m³ .

The weight of that much water is the weight of the truck.

Mass of 1 liter of water = 1 kilogram

1.2285 m³ = 1,228.5 liters = 1,228.5 kg of water.

Weight = (mass) x (gravity)

= (1,228.5 kg) x (9.8 m/s²) = 12,039 Newtons.

(about 2,708 pounds)
