Virty [35]

Answer:

Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A

Explanation:

Let the depth of each section is h.

That means the real depth for each section is h.

Apparent depth is liquid A is 7 cm.

Apparent depth in liquid B is 6 cm.

Apparent depth in liquid C is 5 cm.

by the formula of the refractive index

n = real depth / apparent depth

where, n is the refractive index of the liquid.

For liquid A:

$n_{A}=\frac{h}{7}$ .... (1)

For liquid B:

$n_{B}=\frac{h}{6}$ ..... (2)

For liquid C:

$n_{C}=\frac{h}{5}$ ..... (3)

By comparing all the three equations

nc > nB > nA

Refractive index of liquid C > Refractive index of liquid B > Refractive index of liquid A

An electrostatic paint sprayer has a 0.17 m-diameter metal sphere at a potential of 25.0 kV that repels charged paint droplets o

Troyanec [42]

Answer:

$q=0.236uC$

Explanation:

From the question we are told that:

Diameter $d=0.17m$

Radius $r=0.17/2=>0.085$

Potential $E=25.0kV$

Generally the equation for Potential on spere is mathematically given by

$E=\frac{1}{4 \pi e_0}*\frac{q}{r}$

Therefore

$q=\frac{25*10^3*0.085}{\frac{1}{4 \pi e_0}}$

Where

$\frac{1}{4 \pi e_0}=9*10^9$

Therefore

$q=\frac{25*10^3*0.085}{(9*10^9}}$

$q=0.236uC$

A service elevator takes a load of garbage, mass 10.0 kg, from a floor of a skyscraper under construction, down to ground level,

kobusy [5.1K]

Answer:

The magnitude of the force the garbage exerts on the floor of the service elevator is 12 N

Explanation:

Given;

mass of the garbage, m = 10.0 kg

acceleration of the elevator, a = 1.2 m/s²

The magnitude of the force the garbage exerts on the floor of the service elevator is given by;

F = ma

F = 10 x 1.2

F = 12 N

Therefore, the magnitude of the force the garbage exerts on the floor of the service elevator is 12 N

How do i calculate the net force of the following question.Plz answer correctly

oee [108]

<h2>Explanation:</h2><h2>force = mass×acceleration</h2>

mass=30 force=50

(a) 50÷30 

<h2>because we don't have acceleration which is known as m/s2 that stands for meter per seconds square . Hope this help pls follow thank you</h2>
