You should anticipate a rise in barometric pressure once the core of a mature wave cyclone has passed.

After the core of a mature wave cyclone has passed, what will happen to the barometric pressure? The atmospheric pressure will increase.

With the passage of a cold front, a dramatic change in wind direction is frequently seen. In the warmer air mass ahead of the front, winds are often out of the south-southwest before the front arrives, but as it arrives, winds typically change to the west-northwest (in the colder air mass).

It is moving under the action of gravity such that a g. Using the equation of kinematics as:

v² - u² = 2gs

v = √2gs

v = √2 × 9.8 x 4.9

v = 9.8 m/s

Velocity, quantity that designates how fast and in what direction a point is moving. A point always moves in a direction that is tangent to its path; for a circular path, for example, its direction at any instant is perpendicular to a line from the point to the centre of the circle (a radius). The magnitude of the velocity (i.e., the speed) is the time rate at which the point is moving along its path.

If a point moves a certain distance along its path in a given time interval, its average speed during the interval is equal to the distance moved divided by the time taken. A train that travels 100 km in 2 hours, for example, has an average speed of 50 km per hour.

During the two-hour interval, the speed of the train in the previous example may have varied considerably around the average. The speed of a point at any instant may be approximated by finding the average speed for a short time interval including the instant in question. The differential calculus, which was invented by Isaac Newton for this specific purpose, provides means for determining exact values of the instantaneous velocity.

Because it has direction as well as magnitude, velocity is known as a vector quantity and cannot be specified completely by a number, as can be done with time or length, which are scalar quantities. Like all vectors, velocity is represented graphically by a directed line segment (arrow) the length of which is proportional to its magnitude.

Trough is a linear zone of lower pressure between two areas of high pressure.

An extended area of moderately low atmospheric pressure known as a trough lacks a closed isobaric contour that would classify it as a low pressure area. Troughs and ridges refer to features in the same sense as those on a topographic map since low pressure suggests a low height on a pressure surface.

Troughs could be overhead or close to the ground. A weather front that is accompanied by clouds, showers, and a change in wind direction is occasionally marked by near-surface troughs. The jet stream's upper-level troughs (as depicted in the diagram) are caused by cyclonic filaments of vorticity. Their movement causes upper-level wind divergence, which helps to produce overcast and rainy weather there by elevating and chilling the air ahead of (downstream) the trough.

The restoring force of a spring is 19.25 Newtons

To get the restoring force, we can make use of the formula that is as follows:

F = -k x

When F represents the restoring force, x represents the displacement from equilibrium caused by the deformation, and k represents the constant that is connected to how difficult it is to distort the system, the expression reads as follows. While the minus sign denotes that the restoring force acts in the opposite direction to the displacement, the displacement itself remains constant. Using the formula, we get the following: 55 Newtons per meter multiplied by 0.35 meters.

Therefore, 19.25 Newtons would constitute the restoring force.

Answer:

200ml

Explanation:

To determine the final volume of the gas, you can use the ideal gas law, which states that PV = nRT, where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of the gas, R is the ideal gas constant, and T is the temperature in kelvins.

If you know the initial pressure and volume of the gas, and you raise the pressure to a new value, you can use the ideal gas law to determine the new volume.

For example, if the initial pressure of the gas is 20.5 kPa, the initial volume is 400 mL, the number of moles of the gas is n, the temperature is T, and the pressure is raised to 80.5 kPa, you can solve for the final volume as follows:

P1V1 = nRT

P2V2 = nRT

V2 = (P1V1)/P2

V2 = (20.5 kPa * 400 mL)/80.5 kPa

V2 = 200 mL

So, the final volume of the gas is 200 mL.

It's important to note that this calculation assumes that the temperature and the number of moles of the gas remain constant. If either of these variables changes, the final volume of the gas will also be different.

Impulse is equal to the change in momentum of an object. The momentum of an object is equal to its mass times its velocity.

The initial momentum of the dog is 80kg * 2m/s = 160kg*m/s.

The final momentum of the dog is 80kg * 3m/s = 240kg*m/s.

The change in momentum of the dog is 240kgm/s - 160kgm/s = 80kg*m/s.

Therefore, the impulse on the dog is 80kg*m/s.

Their speed will be  half the initial speed of car A.

The speed of an item, which is a scalar quantity, is the size of the change in its location over time or the size of the change in its position per unit of time.

Any situation in which two or more objects exert forces on one another quickly is referred to as a collision. The scientific definition of the word "collision" makes no reference to the magnitude of the force involved, despite the fact that the most frequent usage of the word relates to instances in which two or more objects clash violently.

Saltation refers to the "bouncing" mode of sand transport in a windstorm or stream. Hence, the option A. Saltation is correct.

Sand can be moved by currents that are driven by gravity, wind, waves, tides, and density (current-related transport), by waves that oscillate as a result of short waves being bent under the impact of depth-decreasing water (wave asymmetry), or by a combination of currents and waves.

Because larger particles are too heavy for the wind to suspend, particles are sand-sized. The wind picks up speed as it climbs and crosses the obstruction. By saltation, it moves the sand grains up the dune's slightly sloping upwind side. The wind's velocity drops as it crosses the dunes.
