what volume will a sample of copper 98.2 g occupy? the density of copper is 8.96 g/mL

Answers

Answer:

Density=mass/volume.

8.96=98.2/volume.

volume=98.2/8.96=10.95982143 ~ 11cm^3.

The volume of a sample of copper of 98.2 g would be 10.95 ml if the density of copper is 8.96 g/mL.

What is density?

It can be defined as the mass of any object or body per unit volume of the particular object or body. Generally, it is expressed as in gram per cm³ or kilogram per meter³.

Due to their superior electrical and thermal conductivities, remarkable resistance to corrosion, and simplicity of production, copper alloys are frequently employed. In general, copper alloys are not magnetic. Electrical wire, cable, contacts, and other components.

As given in the problem the density of copper is 8.96 g/mL, and we have to find the volume occupied by the sample of copper.

mass = density×volume

98.2 g  = 8.96 g/mL×volume

volume =98.2/8.96

            =10.95 ml

Thus, the volume of a 98.2 g sample of copper would be 10.95 ml.

A spherical balloon is being inflated and the radius of theballoon is increasing at a rate of 2 cm/s.(A) Express the radius (r) of the balloon as a function of thetime (t).(B) If V is the volume of the balloon as a function of theradius, find Vor and interpret it.

Answers

Answer:

A.) r = 2t

B.) V = 33.5t^3

Explanation:

Given that a spherical balloon is being inflated and the radius of the balloon is increasing at a rate of 2 cm/s

A) Express the radius (r) of the balloon as a function of the time (t).

Since the rate = 2 cm/s that is,

Rate = radius/ time

Therefore,

2 = r/t

Make r the subject of formula

r = 2t

(B) If V is the volume of the balloon as a function of the radius, find V or and interpret it.

Let assume that the balloon is spherical. Volume of a sphere is;

V = 4/3πr^3

Substitute r = 2t into the formula

V = 4/3π(2t)^3

V = 4/3π × 8t^3

V = 32/3 × πt^3

V = 33.5t^3

if you ran 3.1 miles in 0.5 hours. what was your speed

Answers

Answer:

speed= 6.2 m/hr

Explanation:

distance= 3.1 mile

time=0.5 hours

s=d/t

s=3.1/0.5

speed= 6.2 m/hr

If you run for a distance of 3.1 miles in 0.5 hours, then the speed in miles per hour will be 6.2 m/hr.

What is Speed?

A scalar quantity in kinematics and common usage, an object's speed is the size of the change in its position over time or the amount of change in its position per unit of time.

As the duration of the time interval approaches zero, the instantaneous speed is the maximum limit of the average speed. The distance traveled divided by the duration of the interval represents the average speed of an object over a period of time.

Given information,

Distance covered, d = 3.1 miles

Time taken, t = 0.5 hours

Speed = [tex]Distance/time[/tex]

Speed  = 3.1/0.5

Speed = 6.2 m/hr

Therefore, the speed while running is 6.2 m/hr.

Let G be the garvitational constant and R be the radius of earth. If the radius of the earth becomes half, the new value of gravitational constant will be

Answers

Answer:

G = 1.670 × [tex]10^{-11}[/tex] [tex]m^{3}kg^{-1}s^{-2}[/tex]

Explanation:

From Newton's law of universal gravitation,

F = [tex]\frac{GMm}{R^{2} }[/tex]

Where F is the force of attraction, G is the gravitational constant, M is the mass of the earth, R is the radius of the earth.

From Newton's second law of motion,

F = mg

mg = [tex]\frac{GMm}{R^{2} }[/tex]

g = [tex]\frac{GM}{R^{2} }[/tex]

⇒    G = [tex]\frac{gR^{2} }{M}[/tex]

If the radius of the earth becomes half,

R = [tex]\frac{R}{2}[/tex], then;

G = [tex]\frac{gR^{2} }{4M}[/tex]

Given that: g = 9.8 m/[tex]s^{2}[/tex], radius of the earth is 6371000 m, mass of the earth is 5.972 × [tex]10^{24}[/tex]kg, then;

G   = [tex]\frac{9.8*(6371000)^{2} }{4*5.972*10^{24} }[/tex]

A biker goes out for a ride and begins riding North at 18 km/h for 200 minutes, then the driver turns around and rides at 12 km/h South for another 50 minutes.

Answers

Answer:

Explanation:

18 km / h

= 300 m / min

12 km / h = 200 m / min

distance travelled in 200 minutes = 300 x 200 = 60000 m

distance travelled in 50 minute in return journey = 200 x 50 = 10000 m

total distance travelled = 70000 m

total time = 250 minute

speed = 70000 / 250

= 280 m / min

= 16.8 km / h

Total displacement = 60000 - 10000 = 50000 m

total time = 250 min

velocity = 50000 / 250

= 200 m / min

= 12 km / h

a tungsten and coil has a resistance of 12 ohm at 15 degree celsius is the temperature coefficient of resistance of tungsten is 0.004 calculate the equal resistance at 80 degree Celsius​

Answers

Answer:

The resistance of the tungsten coil at 80 degrees Celsius is 15.12 ohm

Explanation:

The given parameters are;

The resistance of the tungsten coil at 15 degrees Celsius = 12 ohm

The temperature coefficient of resistance of tungsten = 0.004/°C

The resistance of the tungsten coil at 80 degrees Celsius is found using the following relation;

R₂ = R₁·[1 + α·(t₂ - t₁)]

Where;

R₁ = The resistance at the initial  temperature = 12 ohm

R₂ = The resistance of tungsten at the final temperature

t₁ = The initial temperature = 15 degrees Celsius

t₂ = The final temperature = 80 degrees Celsius

α = temperature coefficient of resistance of tungsten = 0.004/°C

Therefore, we have;

R₂ = 12×[1 + 0.004×(80 - 15)] = 15.12 ohm

The resistance of the tungsten coil at 80 degrees Celsius = 15.12 ohm.

27 miles per gallon into kilometers per liter.

Answers

Answer:

11.479 kilometres per litre

Explanation:

for an approximate result, divide the fuel economy value by 2.352

27 miles per gallon is equivalent to approximately 6.09 kilometers per liter.

What is Unit conversion?

A statement of the connection between units that are used to alter the units of a measured quantity without affecting the value is called a conversion factor. A conversion ratio (or unit factor), if the numerator and denominator have the same value represented in various units, always equals one (1).

To convert 27 miles per gallon to kilometers per liter, we need to use conversion factors:

1 mile = 1.60934 kilometers

1 gallon = 3.78541 liters

So, first we convert miles to kilometers:

27 miles * 1.60934 km/mile = 43.45218 kilometers

Then we convert gallons to liters:

1 gallon = 3.78541 liters

27 miles per gallon = 27 miles / 1 gallon = 27 / 3.78541 liters/mile = 7.13888 liters/kilometer

Finally, we divide the distance traveled in kilometers by the amount of fuel used in liters:

43.45218 km / 7.13888 liters = 6.09023 kilometers per liter

Therefore, 27 miles per gallon is equivalent to approximately 6.09 kilometers per liter.

How long is the flea in the air from the time it jumps to the time it hits the ground

Explanation:

an elastic material of length 3m is to be stretched to produce an extension three times it's original length. Calculate the force required to produce the extension if the force constant of the material is 982.3 Newton per metre​

Answers

Answer:

F = 8840.7 N

Explanation:

The parameters given are:

Length L = 3 metres

Extension e = 3 × 3 = 9m

Force constant K = 982.3 Newton per metre​

From Hook's law,

Provided the elastic limit is not extended, the extension is directly proportional to the force applied.

That is,

F = Ke

Substitute all the parameters into the formula

F = 982.3 × 9

F = 8840.7 N

The speed needed to escape the pull of Earth's gravity is 11.3 km/s. What is this speed in mi/h? (1 mile = 1609 m)

Answers

Answer:

11.3 km/sec * 1000 m/km / 1609 m/mi = 7.02 mi / sec

7.02 mi/sec * 3600 sec / hr = 25,300 mph

The value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.

Given the following data;

Speed = 11.3 km/s1 mile = 1609 m

In this exercise, you're required to convert the value of the speed needed to escape the pull of Earth's gravity in kilometer per seconds (km/s) to miles per hour (mi/h).

Conversion:

1 mile = 1.609 kilometer

X mile = 11.3 kilometer

Cross-multiplying, we have;

[tex]1.609[/tex] × X = [tex]11.3[/tex]

[tex]X = \frac{11.3}{1.609}[/tex]

X = 7.0230 miles

Since we know that one (1) hour is equal to 3600 seconds, we would multiply the value of X by 3600 in order to convert it to miles per hour (mi/h).

X = 7.0230 × 3600

X = 25282.8 mi/h

Therefore, the value of the speed needed to escape the pull of Earth's gravity in miles per hour (mi/h) is 25282.8.
