What is the phase of water when its temperature is 150 °C?
A. Solid
B. Liquid
C. Gas
D. None of the above.

Answers

Answer 1

Answer:gas

Explanation:

Answer 2

The phase of water when its temperature is 150 °C is gas. Hence, option (C) is correct.

What are the phases of substance?

Phase is a term used in thermodynamics to describe an amount of matter that is chemically and physically uniform or homogeneous, can be mechanically separated from a nonhomogeneous mixture, and may consist of a single material or a combination of substances.

Although crystalline, colloid, glassy, amorphous, and plasma phases are thought to exist, the three basic phases of matter are solid, liquid, and gas (vapor). A phase change is defined as the transformation of a phase from one form to another.

As the boiling point of water is 100° C, the phase of water when its temperature is 150 °C is gas. Hence, option (C) is correct.

The amount of radiation that a human gets when traveling through space is very toxic this is something that makes it difficult for them to travel as well as the extreme temperatures.

Answer:

There are so many things that make human travel difficult.

Here are some ideas ;

1) Air and Water -Taking water and oxygen from the Earth is very expensive and very difficult. (Note that if there is lots of water, oxygen can be made from the water. Also, if there is carbon dioxide, oxygen can be made.)

2) Food - people will need to grow their own food on another planet - transportation to and from Earth is, again, too expensive. Plants need carbon dioxide and sunlight (real sunlight is best; artificial lighting will work, too.)

3) Energy - Human settlements will need to create their own energy. Energy can be created using the sun.

Note that these powers have their own advantages and disadvantages

4) Radiation - Radiation is harmful for people, plants and animals. On Earth, we are protected by a magnetic field and an atmosphere. Some planets and moons have neither; some have only one or the other. Very few have both. Some planets have very strong magnetic fields that create even more radiation. Crazy right .

5) Gravity - planets or moons with a lesser gravitational pull than the Earth will result in astronauts having smaller bone and muscle mass, which is a serious problem if they are to come back to Earth. The closer a planet's gravity is to Earth, the less of a problem this is.

6) Atmosphere - Some planets have no atmosphere while some have atmospheres that will crush people(Woah ) .It's easier to deal with low-pressure rather than high-pressure, but both are dangerous if there is an air leak.

7) Distance - the further a planet is from Earth, the harder it is to.

8) Temperature - The hotter or colder a planet is, the more energy it will take to change the temperature(and im not really sure how ).

In positional notation, significant figures refer to the digits in a number that is trustworthy and required to denote the amount of something, also known as the significant digits, precision, or resolution.

If a number describing the result of a measurement (such as length, pressure, volume, or mass) includes more digits than the number of digits permitted by the measurement resolution, only the digits allowed by the measurement resolution can be significant figures.

As given in the problem we have to convert 3 x 10⁻⁹ s into milliseconds

1 second = 1×10³ milliseconds

3 x 10⁻⁹ seconds =  (3 x 10⁻⁹)  ×  (1×10³ )

                            = 3 x 10⁻⁶milliseconds

Thus, 3 x 10⁻⁹ s converted into milliseconds it would be 3 x 10⁻⁶ milliseconds

Carlos runs with velocity \vec{v}v →= (5.6 m/s, 29o north of east) for 10 minutes. How far to the north of his starting position does Carlos end up? (Give your answer to the nearest meter)

Answers

Answer:

1629 metres

Explanation:

Given that Carlos runs with velocity v = (5.6 m/s, 29o north of east) for 10 minutes.

To the north, the velocity will be:

V = 5.6 × sin 29

V = 2.715 m/s

Convert the time to second

Time = 10 × 60 = 600

Using the formula below

Velocity = distance/ time

Substitute all the parameters into the formula

2.715 = distance/600

Distance = 2.715 × 600

distance = 1629 m

When velocity is positive and acceleration is negative, what happens to the object’s motion?
a The object speeds up.
b The object remains at rest.
c Nothing happens to the object.
d The object slows down.

Answers

Answer:

Option (D) : The object slows down.

Refer to the position time graph provided to answer questions #1 thru 5.
1. What is the instantaneous velocity of the object at 5 s?

2. What is the distance the object moves from 0 to 9 seconds?

3. What displacement did the object have between 2 s and 9 s?

4. What was the object's average velocity over the first 5 seconds?
5. How many times does the object change direction of travel? (time zero
does not count and standing still does not count as a direction change)

Answers

Answer:

Explanation:

1). To calculate the instantaneous velocity of the object, we will calculate the slope of the line CD.

  Since line CD is a straight line, therefore, slope = 0

  Hence instantaneous velocity = 0

2). Distance of the object when it moves from 0 to 9 seconds

    = Distance traveled from (A to B + B to C + C to D + D to E)

    = 3 + (3 + 0.5) + 0 + 0.5

    = 7 m

3). Displacement = Distance between initial and the final positions of the object

    = 3 - 0

    = 3 m

4). Average velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]

                                 = [tex]\frac{0.5}{5}[/tex]

                                 = 0.1 m per sec

5). Direction changes have been seen at t = 2 sec and t = 4 sec.

   Hence object changed its direction of travel 2 times.

Why is it important to describe motion in universal terms?

Answers

Answer:

Motion requires force to cause that change. The time you take to travel the distance depends upon speed; the distance travelled is measured as the length of a line between the start and end of a motion. It is an important aspect in physics. In our lives motion is important and impacts so many things that we do.

Explanation:

The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.

The motion of an object occurs when there is change in the position of the object with time and the object moves in the direction of the applied force. This motion is influenced by the net force acting on the object.

For example:

The dimension of speed of object in motion is measured with two fundamental quantities (length and time);

speed = LT⁻¹

The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.

A cannon is fired horizontally from the edge of a 100 meter tall cliff. The muzzle velocity of the cannon is 180 m/s . How far from the base of the cliff does the hall land?
A-.55m
B-813.16m
C-3673.47
D-700m

Answers

Answer:

B - 813.16 m

Explanation:

First, find the time it takes to land.  Given in the y direction:

Δy = 100 m

v₀ = 0 m/s

a = 9.8 m/s²

Find: t

Δy = v₀ t + ½ at²

100 m = (0 m/s) t + ½ (9.8 m/s²) t²

t = 4.52 s

Now find the distance traveled in that time.  Given in the x direction:

v₀ = 180 m/s

a = 0 m/s²

t = 4.52 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (180 m/s) (4.52 s) + ½ (0 m/s²) (4.52 s)²

Δx = 813.16 m

A car starts to move from rest after 5 seconds its velocity becomes 15m/s, find the acceleration of the car.​

Answers

Answer:

acceleration of the car is 3 m\s^2

Explanation:

from rest means the initial velocity (vi) is zero

time = 5s

final velocity (vf) = 15m\s

a = vf - vi \ t

a = (15-0) \ 5

a= 3 m\s^2

which means that the car is speeding up 3 meters every second

Answer:

3m/s

Simple

Explanation:

Solution,

U=0

Velocity=15m/s

Time=5 sec

Now,

Acceleration=V-U÷T

=15m/s-0÷5

=15m/s÷5

=3m/s

Hence, the acceleratiob of the car is 3m/s.

Answer:

The final velocity of the ball is 39.2 m/s.

Explanation:

Given that,

A ball is dropped from rest from a high window of a tall building.

Time = 4 sec

We need to calculate the final velocity of the ball

Using equation if motion

[tex]v=u+gt[/tex]

Where, v = final velocity

u = initial velocity

g = acceleration due to gravity

t = time

Put the value into the formula

A. 290,400
B. 8,872 J
C. 580,800 J
D. 13,200 J

Answers

Answer:

A. 290,400

Explanation:

The kinetic energy of a car is 290,400J.

How to find Kinetic energy?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2.

ke = 1/2mv^2

By using the formula, we get

= 1/2 * 1200 * 22^2

= 600 * 484

= 290,400 J

Kinetic energy is a form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.
