The intensity I of light produced by a light source varies inversely as the square of the distance d from the source. If the intensity of light produced 3 metres from a light source is 75 Cd, find the intensity of light produced 5 metres from the same source

Answer: [tex]n>1[/tex]

Step-by-step explanation:

Given

The product of 4 times n is greater than 4 i.e.

[tex]\Rightarrow 4\times n>4\\\text{Dividing both side of inequality by 4}\\\\\Rightarrow \dfrac{4n}{4}>\dfrac{4}{4}\\\\\Rightarrow n>1[/tex]

It can be said that the value of n must be greater than 1.

Answer:

A solid is like the tray being shaken slowly and all the marbles moving in their positions, a liquid is like the tray being shaken and the marbles moving around it, and a gas is like the tray being shaken hard and the marbles moving vigorously around it.

Step-by-step explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states.

Generally, matter exists in three (3) distinct or classical phases and these are;

1. Solid: it is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

2. Liquid: it is the state of matter in which the physical substance can be poured and it takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

3. Gas: it is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

Hence, the statement which best compares the various phase of matter to marbles in a tray is that,

a. All the marbles which are solid move in their positions when the tray is shaken slowly.

b. When the tray is being shaken and the marbles moves around it, this represents a liquid.

c. When the marbles move vigorously around the tray as it's being shaken quickly, this represents the a gas or gaseous state.

Answer:

it's B.

A solid is like the tray being shaken slowly and all the marbles moving in their positions, a liquid is like the tray being shaken and the marbles moving around it, and a gas is like the tray being shaken hard and the marbles moving vigorously around it.

Option D

Step-by-step explanation:

Rule for the reflection of a point (x, y) over the x-axis is given by,

(x, y) → (x, -y)

Applying this rule image point of a point (4, -2) will be,

(4, -2) → (4, 2)

Therefore, Option D will be the correct option.

Answer:

it is asking what name of this solution is and how to solve it

Step-by-step explanation:

Answer:

x= 17

Step-by-step explanation:

Assuming that the total degree of this side is also 90, we'll subtract 90 with 39.

90 - 39= 51

since x is 3 times the total degree, we'll divide 51 by 3, leaving us with 17.

Answer:

18 times

Step-by-step explanation:

Half of the possibilities you can roll are correct. so 18 out of 36 times you roll an odd number.

You could also look at it another way. You can expect to roll each number 6 times, so the 3 odd numbers added together is 18 times.

Answer:

(0,1) point C

Step-by-step explanation:

the line segment PQ is divided into 5 parts ( 3parts +2 parts)

Is very important that you keep the direction correct from P to Q

The point C divides the PQ into 3:2 ratio

(0, 1) is the point that divides the line segment directed from P to Q in the ration of 3 : 2.

Vectorially speaking, we determine the the location of the point that divides the line segment in the ratio of [tex]a : b[/tex].

[tex]R(x,y) = P(x,y) + \frac{a}{a+b}\cdot [Q(x,y) - P(x,y)][/tex] (1)

Where:

If we know that [tex]P(x,y) = (-3, -2)[/tex], [tex]Q(x,y) = (2, 3)[/tex], [tex]a = 3[/tex] and [tex]b = 2[/tex], then the location of the resulting point:

[tex]R(x,y) = (-3, -2) + \frac{3}{5}\cdot [(2,3)-(-3,-2)][/tex]

[tex]R(x,y) = (-3,-2) +\frac{3}{5}\cdot (5, 5)[/tex]

[tex]R(x,y) = (-3, -2) + (3,3)[/tex]

[tex]R(x,y) = (0, 1)[/tex]

(0, 1) is the point that divides the line segment directed from P to Q in the ration of 3 : 2.

Complete Question

A rectangular rug feet is x ft long and y feet wide with a perimeter of 60 ft both X and Y are whole numbers between 10 and 20. Fill in the blanks to complete the sentence. The Area of the rug is greater than___but less than__.

Answer:

he Area of the rug is greater than  but less than [tex]441ft[/tex]

Step-by-step explanation:

From the question we are told that:

Perimeter [tex]P=60ft[/tex]

Value Range:Between 10-20

Generally the Area of the rug is greater than for values of X and Y greater than 9

Therefore Area is greater than from whole number 9

Generally the equation for Area greater than [tex]A_g[/tex] is mathematically given by

[tex]A_l=X*Y[/tex]

Where

[tex]X=9\\Y=9[/tex]

Therefore

[tex]A_l=X*Y[/tex]

[tex]A_l=9*9[/tex]

[tex]A_l=81ft[/tex]

Generally the Area of the rug is less than for values of X and Y less than 21

Therefore Area is less than from whole number 21

Generally the equation for Area greater than A_l is mathematically given by

[tex]A_g=X*Y[/tex]

Where

[tex]X=21\\Y=21[/tex]

Therefore

[tex]A_g=X*Y[/tex]

[tex]A_g=21*21[/tex]

[tex]A_g=441ft[/tex]
