A carton designer is considering cost as she is comparing different shaped cartons. Which of these nets would create a cardboard carton that requires the least amount of cardboard for each cubic inch of volume?.

Answer: The electrostatic force between two point charge particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. So, if you double the individual charges while keeping the same distance, the net electrostatic force will be four times the previous value.

Explanation:

Since, we know

F = (k×q1×q2)/r²

When the charges are doubled, we have :

F' = (k × 2q1 × 2q2)/r²

F' = 4 (k×q1×q2)/r²

Thus,

F' = 4F

Hence, the force becomes 4 times its initial value.

Answer:

increase

Explanation:

The formula for the gravitation for of attraction is:

[tex]F = \dfrac{Gm_1m_2}{r^2}[/tex]

It implies that the force of attraction is inversely proportional to the square of the distance. i.e.

[tex]F \infty \dfrac{1}{r^2}[/tex]

where;

G = gravitational constant

m = mass; &

r = distance between the two objects.

Now let's assume that the distance between is reduced from 1 to half;

Then:

[tex]F \infty \dfrac{1}{\Big (\dfrac{r}{2} \Big)^2}[/tex]

[tex]F \infty \dfrac{4}{r^2}[/tex]

Thus, the new gravitational force of attraction increased by a factor of 4.

Answer:

c

Explanation:

this is because newton's first law of motion states that every object will continue in its state of rest or uniform motion in a straight line unless a resultant force acts on it

so if the resultant force on the refrigerator is 0N, but it was initially moving, it will continue in its motion in a straight line.

it will not change direction since it will continue in its uniform motion.

Answer:

Clouds are formed when moist air rises upward . As the air rises , it becomes colder. Eventually the air can't hold all of the water vapour in it, and some of water vapour condenses to form tiny water droplets... Clouds form at wide range of altitudes , from near the ground to very high in the atmosphere.

Answer:

v = 3.57 m / s

Explanation:

Let's use Newton's second law in the upper part of the circle, with the minimum speed so that the water does not rest on the circle, that is, the normal is zero

          W = m a

acceleration is centripetal

          a = v² / r

let's substitute

         mg = m v² / r

         v = [tex]\sqrt{r g }[/tex]

let's calculate

        v = [tex]\sqrt{1.3 \ 9.8}[/tex]ra 1.3 9.8

Answer:

A

Explanation:

Given that two balls are in motion. A 2-kg ball moving at 4m/s and a 4-kg ball moving at 2m/s, which one has greater kinetic energy? a. 2 kg ball moving at 4 m/s c. Both balls have the same KE b. 4 kg ball moving at 2 m/s d. Cannot be determined

The formula for kinetic energy is :

K.E = 1/2mv^2

A 2-kg ball moving at 4m/s will have kinetic energy of 1/2 × 2 × 4^2

K.E = 16J

and a 4-kg ball moving at 2m/s will have kinetic energy of 1/2 × 4 × 2^2

K.E = 2 × 4

K.E = 8J

which one has greater kinetic energy? Definitely it is a 2 kg ball moving at 4 m/s. Since 16J is greater than 8J. The correct answer is A.

The energy which we obtained from the moving particle is called kinetic energy.  According to the conservation of energy, the energy can neither be created nor be destroyed.

Hence, the formula used in the question is:- [tex]K.E =\frac{1}{2} mv^{2}[/tex] .

Therefore, the kinetic energy of the ball moving the 2kg is 16J.

Hence the Kinetic energy of the ball moving the 4 kg is 8J.

Answer:

It will apply the greatest pressure of an area of 1.

Explanation:

To find pressure use the formula P = F/A

P = 100/1

P = 100

Answer:

10 N / cm^2

Explanation:

The Formiula is P = F / A

P = presure

F = Force in Newtons

A = area.

The answer is the smaller the area the larger the pressure.

The smallest area you have given us is 10 cm^2

The Pressure = 100N / 10 cm^2

Pressure = 10 N/cm^2

Answer:10 km westExplanation:he go 40 east then 50 west 50-40 is 10 so he displaces 10 km and as west is more than east in terms of km so we will say that it's 10 km west pls mark as brainliest thanks

The car's overall displacement if, A car drives 40 km due east and then 50 km due west is 10 km in the west.

Displacement is defined as the overall alteration of an object's location and motion direction. Displacement is recognized as a vector quantity since it takes into account both the direction of the motion and the magnitude of the changing position. Displacement may be zero, positive, or negative.

Given:

A car drives 40 km due east and then 50 km due west,

Consider the west direction as positive and the east direction as negative, then,

The displacement = Displacement in the west + displacement in the east,

The displacement = 50 - 40

The displacement = 10

As the sign is positive, then the direction would be west.

Thus, the displacement of the car is +10 km.

Answer:

Linear expansivity is the fractional increase in length of a specimen of a solid, per unit rise in temperature. If a specimen increases in length from l1 to l2 when its temperature is raised θ°, then the expansivity (α) is given by: l2 = l1(1 + αθ). This relationship assumes that α is independent of temperature. This is not, in general, the case and a more accurate relationship is: l2 = l1(1 + aθ + bθ2 + cθ3…), where a, b, and c are constants.

l2 = l1(1 + αθ).

l2 = l1(1 + aθ + bθ2 + cθ3…),

Answer:

Linear expansivity is the fractional increase in length of a specimen of a solid, per unit rise in temperature. ... Superficial expansivity is the fractional increase in area of a solid surface caused by unit rise in temperature, i.e. A2 = A1(1 + βθ), where β is the superficial expansivity.
