The new speed with respect to the ground is 512 m/h.

We can tell that is speed is the rate at which the velocity changes with respect to time. In this case, we can see that the jet airliner moving initially at 103 mph (with respect to the ground) to the east moves into a region where the wind is blowing at 441 mph in a direction 19° north of east.

Hence;

→ The east component =  103 + 441 cos(52) = 375 m/h

→ The north component = 441 sin(52) = 348  m/h

We can now get the new velocity by the use of;

√( 375)^2 + (348)^2 =

= 512 m/h

A star with apparent magnitude 4 is brighter in our sky than a star with apparent magnitude 14.

Apparent Magnitude is a measure of the brightness of a celestial object, with lower magnitudes indicating brighter objects. The difference in magnitude between the two stars is 10, which means that the star with apparent magnitude 4 is 100 times brighter than the star with apparent magnitude 14.

A star's apparent magnitude is a measurement of how brilliant it seems to be when viewed from Earth. The amount of light coming from a star that reaches us is measured using a logarithmic scale. The apparent magnitude of a star determines how brilliant it seems to us.

The intrinsic luminosity of the star, or its real brightness, and its distance from Earth both have an impact on the apparent magnitude. A star's apparent magnitude will be lower for a star that is intrinsically brilliant and relatively close to us than for a star that is fainter and farther away.

Answer:

F1 = ma = 5.5 kg * 10 m/s² = 55 N  (force acts downwards)

F2 = - 50 N (force acts upwards)

net force = 5 N (downwards)

F = ma

a = F/m

a = 5 / 5.5

a = 0.91 m/s²

Explanation:

Since the object is falling downwards, the air resistance acts upwards. We also have a force acting downwards since the rock experiences gravitational acceleration (the value of g above is 10 m/s² for the sake of easier calculation but you can also set it to be 9.81 m/s² which is the more accurate value). Since the air resistance and force due to gravity are acting in opposite directions and force is a vector, we have to put a minus in front of F1 or F2 (it doesn't matter which direction you chose to be the positive one) . Then we calculate the net force, aka the difference between F1 and F2. Finally, knowing the force and the mass, we can calculate the acceleration.

Answer:

A

Explanation:

Constant speed (without change in direction) is not accelerating. If you are slowing down, speeding up, or changing direction, you are accelerating

Answer:

We mentioned in the study section of Lecture 2 that hydrogen and oxygen combine in the ratio of 1 to 8, but that this is not enough information for leading to the conclusion that two hydrogen atoms combine with one of oxygen to form a water molecule. A key idea is attributed to Avagadro who said that equal volumes of gas (at the same temperature and pressure) contain equal numbers of constituent atoms or molecules. Experiments show that two liters of hydrogen gas will combine with one liter of oxygen gas to form two liters of water vapor. Each hydrogen molecule in hydrogen gas consists of two hydrogen atoms bonded together. Likewise, two oxygen atoms bind to make a oxygen molecule.

A "model" of a physical process is used to represent what one actually observes, even though this is an "ideal" model and not expected to be correct in all respects. However, it is a good enough model to explain many of the properties of gases with sufficient accuracy.

The motion of gas particles can be used to explain the pressure exerted and the temperature of a gas. The pressure on a surface is due to the force on that surface divided by its area. The force comes about from the multiple impacts of individual gas particles. Temperature, on the other hand, is DEFINED in terms of the average kinetic energy assocated with the motion of the gas particles. The greater the kinetic energy, the greater the temperature. See the apparatus shown in Figure 7.6 of the text which gives a simple way of measuring the distributions of speeds of atomic particles.

To visualize how gas particles colliding with a container create pressure, see Website II.

Gas particles move in all possible directions with differing speeds. The Kinetic Energy (KE) of a gas particle is equal to 1/2 its mass times its speeds squared. That is KE = 1/2 M x V2 , where M is the mass of the gas particle and V is its speed. The gas particles have a range of speeds, just like cars on a road, but it is the average of the speed squared times the mass, or the average kinetic energy which characterizes the temperature of a gas.

High temperature is associated with high kinetic energies and low temperatures are associated with low kinetic energies. However, keep in mind that the kinetic energy, and in this case the temperature, is proportional to the mass times the speed squared. So heavy particles moving more slowly will have the same kinetic energy as light particles moving more rapidly. Also, because the kinetic energy varies as the square of the speed, if two particles have the same mass, but one moves twice as fast as the other, it will have four times the kinetic energy (or temperature).

If temperature is associated with kinetic energy of a gas, one could ask at this point what controls the temperature of solids and liquids. It turns out that it is the kinetic energy of the constituent atoms and molecules that characterize the temperature of liquids and solids as well. We show in class a transparency picturing a solid with its atoms rigidly connected to each other. We will discuss more about liquids and solids in the next lecture, based on chapter 8. However, for now, let's keep in mind that the atoms or molecules in a solid, although bound to its neighbors in a rigid structure, can oscillate back and forth, and it is this motion that characterizes the temperature of a solid (or in a similar manner, of a liquid as well). As before, rapid oscillations mean high temperatures, and slower oscillations are lower temperatures.

4 - The Three Temperature Scales

There are three temperature scales. In the United States, we commonly use the Farenheit scale while in most other nations, the Celsius or Centigrade scale is used. Figure 7.10 shows these two scales side by side. Water boils at 212 degrees Farenheit or 100 degrees Centigrade. Water freezes at 32 degrees Farenheit or zero degrees Centigrade. However, the most important temperature scale for scientific calculations is the absolute temperature scale, or the Kelvin scale. Zero degrees Kelvin is the coldest possible temperature: it can be physically interpreted as the situation where the atoms or molecules have zero kinetic energy...so this is a very natural temperature scale. Zero degrees Kelvin is also -273 degrees Centigrade. Water freezes at +273 degrees Kelvin and zero degrees Centigrate. Hence, a difference of one degree is the same on the Centigrade and Kelvin scales, but the zero points are different.

Explanation:

By the first Newton's law, we know that:

every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

Now, we know that the car is moving with constant speed, then there is no net force acting on the car, which means that the car is already in equilibrium.

Then if we add one force to the situation, the car will not be anymore in equilibrium.

The correct option is zero.

Answer:

The sound is louder.

A longitudinal wave in an elastic medium, especially a wave producing an audible sensation.

The intensity of a sound wave is related to the amplitude of the wave, which is a measure of how much the air molecules are displaced from their resting position. When the amplitude of a sound wave increases, it causes more air molecules to be displaced, resulting in a higher sound pressure level and a louder sound.

This relationship between amplitude and perceived loudness is why, for example, turning up the volume on a stereo system increases the amplitude of the sound waves produced, leading to a louder sound.

Atmospheric and oceanic circulation play a crucial role in determining air and ocean water quality at various locations around the globe.

The movement of air and water across the Earth's surface helps to distribute heat, moisture, and pollutants from one region to another. This means that even if you live far away from an area affected by poor air or water quality, you may still be impacted by these conditions.

For example, atmospheric circulation can transport pollutants such as carbon dioxide and ozone from one region to another, affecting global climate patterns and air quality. Additionally, oceanic circulation can transport pollutants and contaminants such as oil spills, plastic waste, and agricultural runoff to distant shores, where they can accumulate and harm marine ecosystems and human health.

Moreover, the effects of climate change, which are influenced by atmospheric and oceanic circulation, are also a major concern for everyone on the planet. Rising temperatures, changing precipitation patterns, and increased frequency of extreme weather events can all have significant impacts on air and water quality, as well as on human health and wellbeing.

In summary, atmospheric and oceanic circulation play a critical role in determining air and water quality around the globe, and their impacts can be far-reaching and long-lasting. It is therefore important for us to understand these complex systems and work towards mitigating their negative effects on our planet and its inhabitants.

a) 2.0 represents the initial position of the ball,  -3.6 represents the initial velocity of the ball  and 1.7 represents the acceleration of the ball.

b)The unit of 2.0 is meters, the unit of -3.6 is meters per second, and the unit of 1.7 is meters per second squared.

c) Position of of ball at t=1, 2, 3 are -1.9, 5.4 and 9.1 meters respectively

d) Average velocity is 5.5 meter per second

Part a

In the equation x = 2.0 - 3.6t + 1.7t2, the number 2.0 represents the initial position of the ball (i.e., the position of the ball at t = 0 seconds), -3.6 represents the initial velocity of the ball (i.e., the velocity of the ball at t = 0 seconds), and 1.7 represents the acceleration of the ball.

Part b

The unit of 2.0 is meters, the unit of -3.6 is meters per second, and the unit of 1.7 is meters per second squared.

Part c

To determine the position of the ball at t = 1.0 s, 2.0 s, and 3.0 s, we simply substitute these values into the equation:

When t = 1.0 s: x = 2.0 - 3.6(1.0) + 1.7(1.0)^2 = -1.9 meters

When t = 2.0 s: x = 2.0 - 3.6(2.0) + 1.7(2.0)^2 = 5.4 meters

When t = 3.0 s: x = 2.0 - 3.6(3.0) + 1.7(3.0)^2 = 9.1 meters

Part d

The average velocity over the interval t = 1.0 s to t = 3.0 s can be calculated by taking the displacement of the ball during this time interval and dividing it by the time interval:

Displacement = x(3.0) - x(1.0) = 9.1 - (-1.9) = 11.0 meters

Time interval = 3.0 s - 1.0 s = 2.0 s

Average velocity = Displacement / Time interval = 11.0 meters / 2.0 seconds = 5.5 meters per second.

The gas company would actually gain money by having gas warmed before it passed through your gas meter. This is because the price of natural gas is determined by volume, but gas meters measure the volume of gas at a standardized temperature and pressure.

This means that if the gas entering the meter is colder than the standardized temperature, it will have a higher volume, and therefore the customer will be charged for more gas than they actually received. By warming the gas before it enters the meter, the volume is reduced and the customer is charged for the actual amount of gas they received.

Therefore, the gas company would gain money by ensuring that gas is warmed before it passes through the meter. It is important to note that there are regulations in place to ensure that gas is not warmed beyond a certain temperature, as this could pose a safety hazard.

The putty ball experiences the greater change in momentum than the tennis ball

The change in momentum of an object is given by the difference between its final momentum and its initial momentum.

We can use the following formula to calculate the change in momentum:

Δp = pf - pi

where;

For the tennis ball, the initial momentum is:

pi = mvi

pi = (0.0567 kg)(10 m/s) = 0.567 kg m/s

The final momentum is:

pf = mvd

pf = (0.0567 kg)(8 m/s) = 0.4536 kg m/s

The change in momentum is therefore:

Δp = pf - pi = 0.4536 kg m/s - 0.567 kg m/s = -0.1134 kg m/s

For the putty ball, the initial momentum is the same as for the tennis ball:

pi = mvi = (0.0567 kg)(10 m/s) = 0.567 kg m/s

Since the putty ball sticks to the wall, its final velocity is zero.

Therefore, the final momentum is:

pf = 0

The change in momentum is therefore:

Δp = pf - pi = 0 - 0.567 kg m/s = -0.567 kg m/s

Comparing the two values, we can see that the putty ball experiences the greater change in momentum, as its momentum decreases by a larger amount (0.567 kg m/s) than the momentum of the tennis ball (0.1134 kg m/s).

Explanation:

While using a wrench, if you double the length of the wrench, it means that you have halved the required force to do the same amount of work. Hence, option (a) is correct.

The definition of force is an external cause that, when applied, affects or tends to modify the state of the body; if the body is in motion, it will come to rest, and if it is at rest, it will go into motion. It may also result in changes to the body's orientation, form, size, etc. An illustration would be using force to push or pull a door.

You would reduce the force by half. More force is needed the nearer you are to the center of mass. Alternatively, try turning one of those round abouts in the park's central area. You'll need to exert much more effort on the system than you would on the bars that are farther from the center.
