Answer:

17404.8 J

Explanation:

The potential energy can be found with the following formula:

\(U=mgh\)

where

U = gravitational energy

m = mass

g = gravitational acceleration

h = height

For this problem:

We are trying to find U

m = 74kg

g = 9.8\(\frac{m}{s^2}\)

h = 24m

So,

\(U=mgh\\U=(74kg)(9.8\frac{m}{s^2})(24m)\\U=17404.8\frac{kg*m^2}{s^2}\\17404.8\frac{kg*m^2}{s^2}=17404.8Joule\)

The gravitational potential energy gained by the person is equal to 17404.8 J.

Gravitational potential energy can be defined as the potential energy of a massive object due to the gravity of the planet. The potential energy is associated with the gravitational field and is released when the objects fall toward each other.

The gravitational field is approximately constant close to the surface of the earth and mathematically we can calculate it as:

U = mgh

Given, the mass of the person, m = 74 Kg

The distance moved upward in the elevator, h = 24 m

The gravitational potential energy of the person will be equal to:

U = 74 × 24 × 9.8

U = 17494.8 J

The net force on particle q1 is approximately 17.12 N to the right.

To calculate the net force on particle q1, we'll use Coulomb's Law: F = k * |q1 * q2| / r^2, where F is the force between two charges, k is the Coulomb's constant (8.99 * 10^9 N m^2/C^2), q1 and q2 are the magnitudes of the charges, and r is the distance between them.

First, we'll find the force between q1 and q2 (F12):
F12 = (8.99 * 10^9 N m^2/C^2) * (8.0 * 10^-6 C) * (3.5 * 10^-6 C) / (0.10 m)^2
F12 = 19.996 N (right)

Next, we'll find the force between q1 and q3 (F13):
F13 = (8.99 * 10^9 N m^2/C^2) * (8.0 * 10^-6 C) * (2.5 * 10^-6 C) / (0.25 m)^2
F13 = 2.8792 N (left)

Now, we'll calculate the net force on q1 (F_net) by subtracting the left force from the right force:
F_net = F12 - F13
F_net = 19.996 N - 2.8792 N
F_net = 17.1168 N (right)

So, the net force on particle q1 is approximately 17.12 N to the right.

b) The spring constant is about 0.18

The force acting on the spring is due to the application of the mass on the spring, which is a product of the mass and the acceleration due to gravity.

Let the force on the spring be due to the mass attached to the spring, we get;

Electric current I enters a node with three resistors connected in parallel (b) I2>I1 and I2>I3.

In a parallel circuit, the voltage across each resistor is the same, but the current through each resistor can be different. So, in this case, the current I will split into three branches as it enters the node, with some current flowing through each resistor. Therefore, option (a) I=I and I2=I3=0 is incorrect.

Since the three resistors are in parallel, the voltage across each resistor is the same. Therefore, the resistor with the lowest resistance will have the highest current flowing through it, while the resistor with the highest resistance will have the lowest current flowing through it. Thus, option (b) I2>I1 and I2>I3 is correct.

The given statement, the spring-mass differential equation my ky '' 0 = results when damping is present, but there is no friction or external force, is false because damping is present in the equation, which accounts for the presence of a dissipative force that opposes the motion of the system, whereas friction and external force are not accounted for in this equation.

The spring-mass differential equation with damping and no external force is given by,

my''(t) + cy'(t) + ky(t) = 0

where m is the mass of the object, k is the spring constant, c is the damping coefficient, and y(t) is the displacement of the object from its equilibrium position.

The second-order term, y''(t), represents the acceleration of the object. The damping term, cy'(t), represents the damping force that is proportional to the velocity of the object. The spring term, ky(t), represents the force due to the spring that is proportional to the displacement of the object.

Therefore, damping is present in the spring-mass system, and the equation is not applicable for the case where there is no damping or external force.

Gravitational potential energy increases as weight and height increases.

Potential energy is stored or conserved energy in a material or object. The amount of stored energy depends on the arrangement, organization, and state of the object or substance.

You might think of it as energy with the "potential" to be productive. Any changes to the object's position, configuration, or status will result in the release of any stored energy.

For instance, in order to compress a spring, energy is required, but what happens to that energy once the spring has been broken It is impossible to generate or destroy energy because it can only transform from one form to another.

This is an interesting scenario! When a cube is balanced with one edge in contact with a table top and with its center of gravity directly above the edge, it is said to be in a state of unstable equilibrium. This means that even a slight disturbance could cause the cube to fall over.

To understand this concept, it is important to first understand what center of gravity means. The center of gravity is the point where the weight of an object is evenly distributed in all directions. In a cube, this point is located at the geometric center of the cube.

Now, in the scenario described, the cube is resting on one of its edges. This edge is acting as a pivot point or fulcrum. When the cube is in this position, its center of gravity is located directly above the pivot point. This means that the weight of the cube is evenly distributed on either side of the pivot point.

However, since the cube is in a state of unstable equilibrium, any slight disturbance could cause the weight distribution to shift. For example, if the table were to vibrate or if there were a gust of wind, the weight distribution could shift slightly, causing the cube to fall over.

Part A:

If the emf frequency is 100 Hz, then the peak current is: 226.19 μA.

Part B:

If the emf frequency is 100 kHz, then the peak current is 22.62 mA.

Further explanation to the above given solution is written below,

Part A:

Using the formula I = C * ΔV/Δt, where C is capacitance, ΔV is the voltage across the capacitor, and Δt is the time period of the AC wave. Since we are given peak voltage, we can find the peak current as follows:

Peak current = (peak voltage * 2π * frequency * capacitance)

Substituting the given values, we get:

Peak current = (24 V * 2π * 100 Hz * 0.90 μF)

Peak current = 226.19 μA.

Part B:

Using the same formula as above, we can find the peak current at a frequency of 100 kHz as follows:

Peak current = (24 V * 2π * 100 kHz * 0.90 μF)

Peak current = 22.62 mA.

We can see that the peak current in Part B is higher than in Part A, which is expected since at higher frequencies, the capacitor can discharge and charge more frequently, leading to a higher peak current.

Answer:

1. Doppler radar

2.Satellite data

3.Radiosondes

4. Automated surface-observing systems

5.Supercomputers

6.AWIPS

Explanation:

1. Doppler Radar is the meteorologist’s window into observing severe storms. With 159 radar towers across the United States, NOAA’s National Weather Service has comprehensive coverage of the continental U.S. and partial coverage of Alaska, Hawaii, Puerto Rico and Guam. Doppler radar detects all types of precipitation, the rotation of thunderstorm clouds, airborne tornado debris, and wind strength and direction.

2.Weather Satellites monitor Earth from space, collecting observational data our scientists analyze. NOAA operates three types of weather satellites. Polar orbiting satellites orbit the Earth close to the surface, taking six or seven detailed images a day. Geostationary satellites stay over the same location on Earth high above the surface taking images of the entire Earth as frequently as every 30 seconds. Deep space satellites face the sun to monitor powerful solar storms and space weather. NOAA also uses data from satellites operated by other agencies and countries.

3.Radiosondes are our primary source of upper-air data. At least twice per day, radiosondes are tied to weather balloons and are launched in 92 locations across the United States. In its two hour trip, the radiosonde floats to the upper stratosphere where it collects and sends back data every second about air pressure, temperature, relative humidity, wind speed and wind direction. During severe weather, we usually launch weather balloons more frequently to collect additional data about the storm environment.

4.ASOS (automated surface observing systems) constantly monitor weather conditions on the Earth’s surface. More than 900 stations across the U.S. report data about sky conditions, surface visibility, precipitation, temperature and wind up to 12 times an hour. Nearly 10,000 volunteer NWS Cooperative Observers collect and provide us additional temperature, snowfall and rainfall data. The observational data our ASOS and volunteers collect are essential for improving forecasts and warnings.

5.NOAA’s Weather and Climate Operational Supercomputer System (WCOSS) is the backbone of modern forecasting. With 5.78 petaflop computing capacity it can process quadrillions of calculations per second. Our supercomputers are almost 6 million times more powerful than your average desktop computer. Observational data collected by doppler radar, radiosondes, weather satellites, buoys and other instruments are fed into computerized NWS numerical forecast models. The models use equations, along with new and past weather data, to provide forecast guidance to our meteorologists.

6.AWIPS (NOAA’s Advanced Weather Information Processing System) is a computer processing system that combines data from all the previous tools into a graphical interface that our forecasters use to analyze data and prepare and issue forecasts, watches, warnings. This system uses NOAA supercomputers to process data from doppler radar, radiosondes, weather satellites, ASOS, and other sources using models and forecast guidance products. After meteorologists prepare the forecasts, AWIPS generates weather graphics and hazardous weather watches and warnings. All this helps our meteorologists create more accurate forecasts and faster than ever before.
