Chapter 17, Problem 1RCQ
To determine
Four common phases of matter
Expert Solution & Answer
Answer to Problem 1RCQ
Solution:
The four common phases of matter are:-
Solid
- Liquid
- Gas
- Plasma
Explanation of Solution
Solids: Solids have definite shape and size. In solids the intermolecular forces between the atoms are very strong.
Liquids: Liquids acquire the shape of the container. In liquid the
Gas: In gases the intermolecular forces between the atoms are very-very small as compared to solids or liquids. So, the gaseous atoms are free to move anywhere. Gas molecules can move in all possible directions with different velocities.
Plasma: Plasma is considered as the fourth state of matter which is discovered recently.A plasma is a hot ionized gas consisting of positively charged ions and negatively charged electrons. The characteristics of plasma is different from gases, so plasma is considered as fourth state of matter
The atoms of the solids are not free to move however they can vibrate about their positions.
intermolecular forces between the molecules are weak as compared to solids. As a result the molecules of liquid can move inside the liquid. Therefore, the liquids do not possess definite shape.
Conclusion:
The four common phases of matter are:-
Solid
- Liquid
- Gas
- Plasma

(a) A luggage carousel at an airport has the form of a section of a large cone, steadily rotating about its vertical axis. Its metallic
surface slopes downward toward the outside, making an angle of 24.5° with the horizontal. A 30.0-kg piece of luggage is placed on
the carousel, 7.46 m from the axis of rotation. The travel bag goes around once in 37.5 s. Calculate the magnitude of the force of
static friction between the bag and the carousel.
Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. N
(b) The drive motor is shifted to turn the carousel at a higher constant rate of rotation, and the piece of luggage is bumped to a
position 7.94 m from the axis of rotation. The bag is on the verge of slipping as it goes around once every 30.5 s. Calculate the
coefficient of static friction between the bag and the carousel.
Your response differs significantly from the correct answer. Rework your solution from the…
(a) Imagine that a space probe could be fired as a projectile from the Earth's surface with an initial speed of 5.78 x 104 m/s relative
to the Sun. What would its speed be when it is very far from the Earth (in m/s)? Ignore atmospheric friction, the effects of other
planets, and the rotation of the Earth. (Consider the mass of the Sun in your calculations.)
Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your
calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. m/s
(b) What If? The speed provided in part (a) is very difficult to achieve technologically. Often, Jupiter is used as a "gravitational
slingshot" to increase the speed of a probe to the escape speed from the solar system, which is 1.85 x 104 m/s from a point on
Jupiter's orbit around the Sun (if Jupiter is not nearby). If the probe is launched from the Earth's surface at a speed of
4.10 x 10 m/s relative…

During the one-armed maneuver first developed in the 1940s, the outstretched arm of the male skater must apply a large force to support a significant fraction of the female skater's weight and also to provide her centripetal acceleration.

Solid pieces of fruit are chopped into granules by cutters at the bottom of the spinning cone. Then the fruit granules rapidly make their way to the sloping surface where the juice is extracted to the outside of the cone through the mesh perforations.

This slide was unique for its time due to the fact that a large number of small wheels along its length made friction negligible.

The chute was 9.76 m high at the top and 54.3 m long. Consider a rider and sled with a combined mass of 81.0 kg.

- Because you are taking physics, your friend asks you to explain the detection of gravity waves that was made by LIGO in early 2016. (See the section that discusses LIGO.) To do this, you first explain about Einstein's notion of large masses, like those of stars, causing a curvature of spacetime. (See the section on general relativity.) To demonstrate, you put a bowling ball on your bed, so that it sinks downward and creates a deep depression in the mattress. Your sheet has a checked pattern that provides a nice coordinate system, as shown in the figure below. This is an example of a large mass (the bowling ball) creating a curvature of a flat, two-dimensional surface (the mattress) into a third dimension. (Spacetime is four dimensional, so its curvature is not easily visualized.) Then, you are going to amaze your friend by projecting a marble horizontally along a section of the sheet surface that is curved downward by the bowling ball so that the marble follows a circular path, as…arrow_forwardQ6: Water in a river 1.6 km wide flows at a speed of 6.0 km h−1.
