Question 20

fenix001 [56]

Answer:

(b) Water

Explanation:

The density of the liquid is found by dividing its mass by its volume.

The mass of the liquid is the difference in mass between the full and empty graduated cylinder:

liquid mass = (145 g) -(45 g) = 100 g

<h3>volume</h3>

The cylinder is said to contain 100 mL of the liquid, so that is the volume of interest.

<h3>density</h3>

The ratio of mass to volume is the liquid's density:

ρ = (100 g)/(100 mL) = 1 g/mL

This density identifies the most likely liquid as water.

A mass with a charge of 4.60 x 10-7 C rests on a frictionless surface. A compressed spring exerts a force on the mass on the lef

stira [4]

Answer:

The compression of the spring is 24.6 cm

Explanation:

magnitude of the charge on the left, q₁ = 4.6 x 10⁻⁷ C

magnitude of the charge on the right, q₂ = 7.5 x 10⁻⁷ C

distance between the two charges, r = 3 cm = 0.03 m

spring constant, k = 14 N/m

The attractive force between the two charges is calculated using Coulomb's law;

$F = \frac{kq_1q_2}{r^2} \\\\F = \frac{(9\times 10^9)(4.6\times 10^{-7})(7.5\times 10^{-7})}{(0.03)^2} \\\\F= 3.45 \ N$

The extension of the spring is calculated as follows;

F = kx

x = F/k

x = 3.45 / 14

x = 0.246 m

x = 24.6 cm

The compression of the spring is 24.6 cm

defon

Answer:

Explanation:

Volume per unit time flowing will be conserved

a₁v₁ = a₂ v₂

π r₁² x v₁ = π r₂² x v₂

(0.9 x 10⁻²)² x .35 = ( .45 x 10⁻² )² x v₂

v₂ = 1.4 m / s
