A steel ball whose mass is 100 g is rolling at a rate of 2.8 m/sec. What is it’s momentum?
Answer:
The momentum of the steel ball is 0.28 kg m/sec.
Explanation:
The momentum of an object can be calculated using the formula: momentum = mass x velocity. In this case, the mass of the steel ball is 100 g, which is equivalent to 0.1 kg. The velocity of the ball is 2.8 m/sec. Plugging in the values into the formula, we get:
momentum = 0.1 kg x 2.8 m/sec
momentum = 0.28 kg m/sec
So the momentum of the steel ball is 0.28 kg m/sec.
a rotating fan completes 1200 revolutions every minute. consider the tip of a blade, at a radius of 0.15 m. (a) through what distance does the tip move in one revolution? what are (b) the
The angular velocity of the tip of the blade is angular velocity = 2 * π * 1200 rotations / minute = 7539.82 rad/min.
(a) To find the distance the tip of the blade moves in one revolution, we can use the circumference of a circle:
distance = 2 * π * radius = 2 * π * 0.15 m = 0.94 m
So, the tip of the blade moves a distance of 0.94 meters in one revolution.
(b) To find the linear velocity of the tip of the blade, we can use the formula for linear velocity:
linear velocity = distance / time = 2 * π * radius * rotations / minute
Since the fan completes 1200 revolutions per minute, the linear velocity is:
linear velocity = 2 * π * 0.15 m * 1200 rotations / minute = 94.25 m/s
To find the angular velocity of the tip of the blade, we can use the formula for angular velocity:
angular velocity = 2 * π * rotations / minute
So, the angular velocity of the tip of the blade is:
angular velocity = 2 * π * 1200 rotations / minute = 7539.82 rad/min.

explain how a light material, such as fiberglass insulation, makes an effective barrier to keep a home warm in the winter and cool in the summer.
Fiberglass insulation makes an effective barrier to keep a home warm in the winter and cool in the summer because it traps air between the fibres.
By trapping air between the fibers, fiberglass insulation functions as an efficient barrier to keep homes warm in the winter and cool in the summer. As a result, the quantity of heat transmission between homes and the outside is considerably reduced, resulting in low conductive insulation.
Fiberglass performs admirably as a thermal insulator. It works well as acoustic insulation as well. Specialized acoustic glasswool batts are the best choice for energy-efficient soundproofing of your home. The thickness and R-Value of a fiberglass product determine how well it can withstand heat flow.

Two identical metal balls are suspended by insulating threads. Both balls have the same net charge. In this problem, do not assume the balls are point charges.(a) Draw a separate free-body diagram for each ball. Label the forces.(b) Suppose the charge on the second ball is reduced slightly so that it is less than that on the first ball. Predict whether the angle that ball 1 makes will be greater than, less than, or equal to the angle that ball 2 makes with the vertical. Explain.(c) Predict what will happen if the net charge on ball 2 is reduced to zero. Make a sketch to illustrate your answer.
In this situation, both balls will exert electrostatic force on each other in the first example.
Here, in the first scenario, both balls will interact electrostatically. The two balls will reject one another as a result of this electrostatic force.In addition, there will be a vertical downward gravitational force acting on the two balls.
Now that we know, the angle between the two balls will be greater as the horizontal force separates the two balls as the electrostatic force of repulsion between the two balls increases.
As we decrease the charge on one ball, the net electrostatic force between the two balls also reduces since we know that the net electrostatic force between two balls depends on the product of two charges.
The two balls then travel closer to one another as the angle between them diminishes. Additionally, we can see from the free body diagram of two balls that all of the forces acting on the balls are the same; as a result, both balls' angles of inclination with respect to the vertical are same.
Because of this, the angle created by ball l with the vertical equals the angle formed by ball 2.

a man skis down from the top of a hill 1450.0 m high, starting from rest. if he loses 70% of his initial mechanical energy to friction during his descent, what is his speed in m/s at the base of the hill?
Speed of a man at the base of the hill is 93.27m/sec if a man skies down from the top of hill 1450m high.
In actual sciences, mechanical energy is the amount of possible energy and motor energy. The rule of preservation of mechanical energy expresses that in the event that a disengaged framework is subject just to moderate powers, the mechanical energy is consistent. In the event that an item moves the other way of a moderate net power, the potential energy will increment; and if the speed (not the speed) of the item changes, the dynamic energy of the item likewise changes.
In every single genuine framework, nonetheless, non-conservative powers, for example, frictional powers, will be available, however in the event that they are of irrelevant greatness, the mechanical energy changes nearly nothing and its protection is a valuable estimation. In flexible crashes, the active energy is moderated, yet in inelastic impacts some mechanical energy might be changed over into nuclear power. The comparability between lost mechanical energy and an expansion in temperature was found by James Prescott Joule.
At 1450m height,mechanical energy is equal to potential energy. Potential energy is all due to position of man.
Potential energy=mgh where m is the mass and g is the acceleration due to gravity and h is the height.
So,potential energy=m×10×1450Joules.
Now,when he starts from rest and losses 70% of energy in friction,it means 30% mechanical energy will convert into kinetic energy.
So,30% of mechanical energy=kinetic energy of man.
=>(30/100) ×m×10×1450=(1/2)×m×v²
=>3×1450×2=v²
=>v²=8700
=>v=√8700
=>v=93.27m/sec.
Hence,speed of man at base is 93.27m/sec.

Use evidence and scientific reasoning to explain why the reading on the balance increased as Magnet 2 was lowered towards Magnet 1. Remember that Magnet 1's North pole was facing upwards while resting on the balance. In your response, be sure to describe the magnetic field interactions and the orientation of the magnetic poles for each magnet
The increase in the reading on the balance as Magnet 2 was lowered towards Magnet 1 was due to the interaction between the magnetic fields of the two magnets and the orientation of their magnetic poles, leading to an increase in the overall magnetic field strength.
When Magnet 2 was lowered towards Magnet 1, the reading on the balance increased because of the interaction between the magnetic fields of the two magnets.
Magnet 1, with its North pole facing upwards, creates a magnetic field with lines of force flowing out of the North pole and into the South pole. This creates a magnetic field that is stronger near the North pole and weaker near the South pole.
When Magnet 2 was brought near Magnet 1, the magnetic field of Magnet 2 interacts with the magnetic field of Magnet 1.
If the North pole of Magnet 2 is facing the South pole of Magnet 1, the magnetic fields of the two magnets will reinforce each other, leading to an increase in the overall magnetic field strength.
This increase in magnetic field strength can be detected by the balance, causing the reading to increase.
It's important to note that the orientation of the magnetic poles and the direction of the magnetic field lines play a crucial role in the magnetic field interactions between two magnets.
If the North pole of Magnet 2 was facing the North pole of Magnet 1, the magnetic fields would repel each other, causing the reading on the balance to decrease.

when the tr and tc curves have the same slope,
When the TR and TC curves have the same slope, the firm is operating at its profit-maximizing output level, which allows the firm to earn the highest possible economic profit.
In microeconomics, the Total Revenue (TR) and Total Cost (TC) curves are important tools for understanding the behavior of firms in a competitive market. When the TR and TC curves have the same slope, the firm is said to be operating at its profit-maximizing output level. In this scenario, the firm earns the highest possible economic profit, which is the difference between total revenue and total cost.
To understand why the profit-maximizing output occurs when TR and TC curves have the same slope, we need to consider the following:
Marginal revenue (MR) is the additional revenue earned by a firm for selling one more unit of output. MR is equal to the slope of the TR curve.
Marginal cost (MC) is the additional cost incurred by a firm for producing one more unit of output. MC is equal to the slope of the TC curve.
The profit-maximizing output level occurs where MR = MC. At this output level, the additional revenue earned from selling one more unit of output (MR) is equal to the additional cost incurred from producing one more unit of output (MC).
When the TR and TC curves have the same slope, it means that MR = MC. This condition implies that the firm is operating at its profit-maximizing output level. At this output level, the firm earns the highest possible economic profit, which is the difference between total revenue and total cost.
If the slope of the TR curve is greater than the slope of the TC curve, then MR > MC, which means that the firm can increase its profit by producing and selling more output. Conversely, if the slope of the TC curve is greater than the slope of the TR curve, then MR < MC, which means that the firm can increase its profit by producing and selling less output.

A refracting and reflecting telescope have the same diameter; the refracting telescope will be much longer than the reflector'
The answer choice is true.
Because refracting and reflecting telescopes are designed differently, they can have different lengths even though they have the same diameter. Refracting telescopes, commonly known as refractors, bend and concentrate light to create images. The length of a refractor is mostly dictated by the size of its objective lens, which is the primary light-gathering lens at the front of the telescope. A bigger lens necessitates a longer tube in order to accommodate it, resulting in a greater overall length of the telescope.
Reflecting telescopes, also known as reflectors, on the other hand, employ mirrors to gather and focus light. The length of a reflector telescope is dictated by the size of its primary mirror. A longer optical tube is required to accommodate a larger mirror, but it does not have to be as long as a refractor of the same diameter because the light from the mirror travels a shorter distance before reaching the eyepiece.
Even if a refractor and a reflector have the same diameter, the refractor will be considerably longer due to the length necessary to accommodate its huge lens, but the reflector will have a lower overall length since the light it gathers travels a shorter journey.

At the top of the mountain where the ambient pressure is 11.5 psi, your tire pressure gauge reads 28 psig. After riding down the mountain to sea level where the ambient pressure is 14.7 psi. The tire pressure gauge at sea level will read 24.8 psig.
In this case, we can start by converting the gauge pressure at the top of the mountain (28 psig) to absolute pressure (pa) using the formula:
pa = gauge pressure + ambient pressure
pa = 28 psig + 11.5 psi
pa = 39.5 psi
At sea level, the ambient pressure is 14.7 psi, so the gauge pressure (pg) can be calculated as:
pg = pa - ambient pressure
pg = 39.5 psi - 14.7 psi
pg = 24.8 psig

What is force?
Force is an influential physical quantity that can cause an object to change its velocity and/or shape. It is a vector quantity meaning it has both magnitude and direction.
Forces can cause objects to accelerate, decelerate, or change direction. Examples of forces include gravitational force, electromagnetic force, and frictional force. Force is measured in units of Newtons (N). Force is an important concept in physics as it is one of the fundamental concepts of the subject.
Since the weight of each box is determined by its mass, the box with the largest mass will have the greatest.
