A hot air balloon holds 7.40 x 107 liters of gas. In order for the hot air balloon to rise into the sky, it must be heated to 120°C. Once the balloon is up in the air, the air needs to be cooled in order for the balloon to land. If the temperature of the balloon is decreased to 40.0°C, what will the new volume of the gas be?

Remember to pay close attention to the units of temperature before beginning your calculations.

Answers

Answer:

2.467×10^7 litres

Explanation:

Using the formula V1/T1 = V2/T2

V1 and V2 are the initial and final volume respectively

T1 and T2 are their respective temperatures

Given

V1 = 7.4×10^7litres

T1 = 120°C

T2 = 40°C

Required

V2

From the formula

V2 = V1T2/T1

V2 = 7.4×10^7(40)/120

V2 = (7.4×10^7)/3

V2 = 2.467×10^7 litres

Hence the new volume of the gas will be 2.467×10^7 litres

a traveller covers 1.2km distance in 5mins find it's average velocity​

Answers

Explanation:

Average Velocity = Displacement / Time

= 1.2km / 5 min

= 1200m / 300s

= 4m/s.

The average velocity of a moving body is the distance covered by time. The average velocity of the traveler covers 1.2 km in 5 min is 4 m/s.

What is velocity ?

Velocity is a physical quantity which measures the distance travelled per unit time. Velocity is a vector quantity thus having both magnitude and direction.

Velocity is the ratio of distance to the time. Given that the distance travelled by the man = 1.2 km = 1200 m

time = 5 min = (5 × 60 s) = 300 s.

Thus, velocity = distance/ time

                       = 1200 m / 300 s

                       = 4 m/s.

Therefore, the velocity of the traveler is  4 m/s.

Block on inclined plane experience a force due to gravity of 300N straight down. If the slope is inclined at 67.8°to the horizontal. What is the component of the force due to gravity perpendicular and parallel to the slope?

Answers

Answer:

The component of the force due to gravity perpendicular and parallel to the slope is  113.4 N and 277.8 N respectively.

Explanation:

Force is any cause capable of modifying the state of motion or rest of a body or of producing a deformation in it. Any force can be decomposed into two vectors, so that the sum of both vectors matches the vector before decomposing. The decomposition of a force into its components can be done in any direction.

Taking into account the simple trigonometric relations, such as sine, cosine and tangent, the value of their components and the value of the angle of application, then the parallel and perpendicular components will be:

Fparallel = F*sinα =300 N*sin 67.8° =300 N*0.926⇒ Fparallel =277.8 N Fperpendicular = F*cosα =  300 N*cos 67.8° = 300 N*0.378 ⇒ Fperpendicular= 113.4 N

The component of the force due to gravity perpendicular and parallel to the slope is  113.4 N and 277.8 N respectively.

A plane lands and comes to a complete stop. If the plane covers 200 m and decelerates at 7.5 m/s2 , what was the planes initial velocity as it touched the runway?

Answers

Answer:

The initial velocity of the plane is 54.77 m/s

Explanation:

Given;

distance covered by the plane, d = 200 m

deceleration of the plane, a = - 7.5 m/s²

The initial velocity of the plane is given by the following kinematic equation;

v² = u² + 2ad

where;

v is the final velocity of the plane when the plane comes to a complete stop = 0

u is the initial velocity of the plane

0 = u² + 2(-7.5 x 200)

0 = u² - 3000

u² = 3000

u = √3000

u = 54.77 m/s

Therefore, the initial velocity of the plane is 54.77 m/s

A mover slides a refrigerator weighing 650 N at a constant velocity across the floor a distance of 8.1 m. The force of friction between the refrigerator and the floor is 230
N. Calculate the coefficient of friction between the floor & refrigerator.

Answers

Answer: The coefficient of friction is 0.35

Explanation:

We can write the friction force as:

F = N*μ

Where N is the normal force between the refrigerator and the ground, as the full weight of the refrigerator is acting on the ground, the normal force will be exactly equal to the weight of the refrigerator, then:

N = 650N

And μ is the coefficient of friction.

And for this case, the force is 230N, then we have:

F = N*μ

230N = 650N*μ

(230N/650N) = μ = 0.35

Notice that the distance did not matter for this calculation.

Determine the energy lost, due to friction, as an 8000 N car that skids to a stop, if its initial velocity was 12 m/s.

Answers

Answer:

58,800Joules

Explanation:

The energy lost is equal to the workdone by the car as it skids.

Workdone = Force * Distance

Given

Force = 8000N

Get the distance using the equation of motion

v² = u² - 2gS

0² = 12² - 2(9.8)S

-12² =  - 2(9.8)S

-144 = -19.6S

S = 144/19.6

S = 7.35m

Calculate the required energy

Workdone = 8000 * 7.35

Workdone = 58,800Joules

Hence the energy lost due to friction is 58,800Joules

pls answer fast I will mark as brainlist ​

Answers

Answer:

1. 12 g/cm³

2. 0.5 m

Explanation:

1.

The weight of the gold is 240 g

The volume is 20 cm³

Density = Mass/ volume

Density = 240 / 20 = 12 g/cm³

2.

The formula for moment of a force is ;

Force * distance perpendicular  between force and the turning point of force

Given that the moment of force is 12.5 Nm and force is 25 N  then the perpendicular distance between the force and the turning point will be;

12.5 = 25 * d

12.5/25 = d

0.5 = d

d= 0.5 m

What is the tangential velocity of a record player which makes 11 revolutions in 20 seconds?

Answers

What is the tangential velocity of a record player which makes 11 revolutions in 20 seconds? Help hello

Velocity is defined as rate of change of displacement wit respect to time.

tangential velocity is  (11/10)πr , where r is radius of circular track.

Since, tangential velocity is,  [tex]=\frac{distance}{time}[/tex]

In one revolution, distance travelled is circumference of circular track.

If radius of circular track is r , then distance travelled in one revolution is, = 2πr  

So, 11 revolutions = 11(2πr) = 22πr

Time taken = 20 second

So, tangential velocity = 22πr/20 = (11/10)πr  meter per second.

---Spring Question---
A 0.84 kg ball is held at rest against a spring (k = 142 N/m) that has been compressed 0.06 m. The ball and spring are on a table and the ball is 2.0 m above the ground. If friction between the ball and the table is negligible, then how far from the edge of the table (in meters) will the ball hit the ground?

Answers

Answer:

The distance from the edge of the table at which the ball will hit the ground is approximately 0.49 meters

Explanation:

The mass of the ball = 0.84 kg

The spring constant k = 142 N/m

The compression of the spring = 0.06

Therefore, by conservation of energy, we have;

The potential energy of the spring = The kinetic energy given to the ball

The potential energy of the spring = 1/2 × k × x² = 1/2 × 142 × 0.06² = 0.2556

The potential energy of the spring = 0.2556 J

The kinetic energy given to the ball = 1/2 × m × v²

Where;

v = The final velocity of the ball

Substituting gives;

1/2 × 0.84 × v² = 0.2556

∴ v = √(0.2556/(1/2 × 0.84)) ≈ 0.78

The final velocity of the ball = v ≈ 0.78 m/s

The height of the ball above the ground, h = 2.0 m

Therefore, we have;

The time, t, it takes the ball to touch the ground from the 2.0 m height, h, is given as follows;

h = 1/2·g·t²

t = √(2·h/g)

Where;

g = The acceleration due to gravity = 9.81 m/s²

∴ By substitution, we have;

t = √(2 × 2/9.81) ≈ 0.63855

t ≈ 0.63855 s

The distance from the edge of the table at which the ball will hit the ground = The horizontal distance covered during before the ball hits the ground

The horizontal distance covered during before the ball hits the ground = The (horizontal) velocity of the ball × The time it takes the ball to touch the ground

∴ The horizontal distance covered during before the ball hits the ground = 0.78 × 0.62855 ≈ 0.490269 ≈ 0.49

The distance from the edge of the table at which the ball will hit the ground = The horizontal distance covered during before the ball hits the ground  ≈ 0.49 m

Birdman is flying horizontally at a
speed of 40 m/s and a height of 58
m. Birdman releases a turd directly
above the start of the field. How far
from the start of the field should the
robot hold the bucket to catch the
turd?

Answers

Answer:

The robot should hold the bucket at 137.6 m from the start of the field

Explanation:

Horizontal Motion

When an object is launched horizontally with a speed v from a height h, it describes a curved path exclusively ruled by gravity until it eventually hits the ground.

The range or maximum horizontal distance d traveled by the object can be calculated as follows:

[tex]\displaystyle d=v\cdot\sqrt{\frac {2h}{g}}[/tex]

Birdman flies horizontally at a  speed of v=40 m/s and a height of h=58  m. He releases a turd above the start of the field. If the robot was exactly down  Birdman, then it won't catch the turd with the bucket because it would land farther away by a distance equal to the range. Thus:

[tex]\displaystyle d=40\cdot\sqrt{\frac {2*58}{9.8}}[/tex]

[tex]\displaystyle d=40\cdot\sqrt{11.84}[/tex]

d = 137.6 m

The robot should hold the bucket at 137.6 m from the start of the field
