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

Answer:

3 m/s

Explanation:

First, find the time it takes to land.

Given in the y direction:

Δy = 0.8 m

v₀ = 0 m/s

a = 10 m/s²

Find: t

Δy = v₀ t + ½ at²

0.8 m = (0 m/s) t + ½ (10 m/s²) t²

t = 0.4 s

Next, find the velocity needed to travel 1.2 m in that time.

Given in the x direction:

Δx = 1.2 m

a = 0 m/s²

t = 0.4 s

Find: v₀

Δx = v₀ t + ½ at²

1.2 m = v₀ (0.4 s) + ½ (0 m/s²) (0.4 s)²

v₀ = 3 m/s

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.

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.

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.

C.) 90 kg

Explanation:

A.) If Justin races his Chevy S-10 down highway 37 north for 2,560 meters in 60 seconds, what is his velocity? 

Velocity = displacement/time

Velocity = 2560/60

Velocity = 42.67 m/s

B.) The Chevy S-10 started rounding at 10 meters per hour. What is the acceleration at 30 seconds on the highway?

Acceleration = velocity/time

Acceleration = 10/30

Acceleration = 0.33 m/s^2

C.) The S-10 has a force of 30 N. What is the mass of the car?

Force = mass × acceleration

30 = mass × 0.33

Mass = 30/ 0.33

Mass = 90 kg

So to increase current of the circuit what you can do is :

1. Use conductor of low resistivity, ¶.

2. Use conductor of small length.

3. Use thick wire.

4. Decrease the temperature of the circuit.

5. If operating temprature is high than use semiconductor, because it have negative temprature coefficient.

6. Minimise the circuit losses.

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;

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.

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.

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.

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.

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.

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

momentum can also be defined in terms of newton second

that is P=F.V

now v =vf-vi

v=3 m/s-1m/s=2 m/s

now F=W=45 kg

therefore

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
