You are given a sample of metal and asked to determine its specific heat. you weigh the sample and find that its weight is 28.4 n. you carefully add 1.25 x 104 j of heat energy to the sample and find that its temperature rises to 18.0 °c. what is the sample’s specific heat?

Answers

Answer 1

The specific heat of the given sample of metal is 14.32 J/kg.K.

What is the Specific heat of a sample?

The specific heat of a sample is the amount of heat needed or required to raise the temperature of that sample by 1K. It is given by the formula:

Q = mCΔT

where;

Q = Heat transferredm = Mass of the substanceC = Specific heat ΔT= Change in temperature.

Recall that:

weight of a substance = mass × gravity

mass = 28.4 N/ 9.8 m/s²mass = 3 N/m/s² = 3 kg

From the equation:

Q = mCΔT

[tex]\mathbf{C = \dfrac{1.25 \times 10^4 \ J}{3 \ Kg \times 291 \ K }}}[/tex]

C = 14.32 J/kg.K

Max bought a new speed boat that cost of $33,000. the boat depreciates approximately 18% of its value each year. write an equation to model the value of the speed boat.

Answers

The equation that can be used to model the value of the speed boat is; y = 33,000 × (0.82)^t

How to write equation?

cost of the boat = $33,000Rate of depreciation each year = 100% - 18%

= 82%

= 0.82

The equation;

y = A × (b)^t

A computer’s memory is composed of 8k words of 32 bits each. how many total bytes in memory?

Answers

The number of total bytes in memory is 32,000 bytes.

How many total bytes in memory?

We know that the memory is composed of 8k (or 8,000) words of 32 bits each.

To get the total memory, we just need to take the product between the number of words and the memory that each has.

This will give:

8,000*(32 bits) = 256,000 bits.

But we want this in bytes so we need to change the units, remember that:

1 bit = 0.125 byte.

Then we have:

256,000 bits = 256,000*( 0.125 byte) = 32,000 bytes.

The memory has 32,000 bytes in total.

The moment of inertia for rotation about the perpendicular axis through the edge of the disk is 3.78 × 10⁻⁵ kgm².

Moment of inertia

Moment of inertia is referred to as the product of mass of section and the square of the distance between the reference axis and the centroid of the section.

Moment of inertia of solid cylinder or disk is expressed as;

I = 1/2 × mr²

Mass of disk m = 21g = 0.021kgDiameter of disk d = 12cm = 0.12mRadius r = d/2 = 0.12m / 2 = 0.06mMoment of inertia I = ?

We substitute our given value into the expression above.

I = 1/2 × 0.021kg × (0.06m)²

I = 1/2 × 0.021kg × 0.0036m²

I = 3.78 × 10⁻⁵ kgm²

Answers

The dmension of the rectangle with perimeter of 68 m has the largest possible area as 17m by 17m.

Perimeter of a rectangle

perimeter of rectangle = 2(l + w)

where

l = lengthw = width

Therefore,

perimeter = 68 m

68 = 2l + 2w

l + w = 34

l = 34 - w

Hence, the largest possible area is at the amximum.

area = lw

area = w(34 - w)

area = 34w - w²

The maximum is at dA / dw = 0

Therefore,

34 - 2w  = 0

2w = 34

w = 34 / 2

w = 17

From the complete question, we have the following side lengths

Opposite = 5.7 cmAdjacent = 3.2 cm

The hypotenuse of the triangle is then calculated as:

Hypotenuse^2 = Opposite^2 + Adjacent^2

This gives

Hypotenuse^2 = 3.2^2 + 5.7^2

The autonomic nervous

This system regulates certain body processes such as blood pressure and respiratory rate. It works automatically (autonomously) without the person's conscious effort.

The path of an autonomic nerve involves two nerve cells. One of them is located in the brain stem or spinal cord. It is connected by nerve fibers to another cell, located in a group of nerve cells (called autonomic ganglia). Nerve fibers from these ganglia connect with internal organs.
