Which front is a head on collision or neither warm nor cold air moves

1 answer:

3 0

Stationary wave fronts are formed when two air masses of different densities and temperature range push each other but unable to move the front in any direction.

<u>Explanation:</u>

Weather Fronts

When collision happens between air masses of two with varied densities and the temperature, they form a front. These air masses also differ in humidity. When a cold front and warm front generated and push each other equally, the net force turns to be zero and there is no movement in any of the front.

By this, both of the fronts form a stationary row which separates both the fronts. Both kind of winds flow perpendicular to each other rather than parallel and this what holds the stationary front in place.

If the winds change the directions, the front may also move in the direction of the wind which is dominating the the other one. The weather seems to be often cloudy with this front. Hence, in the state of the formation of a stationary front, neither warm nor cold air moves parallel.

Kobotan [32]

The student's claim did not follow the scientific method of discovery, hence, it is an opinion not a scientific claim.

<h3>What is the scientific method?</h3>

The scientific method is a procedure employed by scientific towards understanding the world around them as well giving explanation for phenomena in the natural world.

The scientific method involves:

observations
asking questions
putting forward a hypothesis
testing the hypothesis through experiments
analyzing results of the experiments and drawing conclusions
establishing a theory.

Since the student in question just put forward an opinion without testing it out using the scientific method, the statement is not a scientific claim.

A box is initially sliding across a frictionless floor toward a spring which is attached to a wall. the box hits the end of the

Serjik [45]

The elastic potential energy of a spring is given by
$U= \frac{1}{2}kx^2$
where k is the spring's constant and x is the displacement with respect to the relaxed position of the spring.

The work done by the spring is the negative of the potential energy difference between the final and initial condition of the spring:
$W=-\Delta U = \frac{1}{2}kx_i^2 - \frac{1}{2}kx_f^2$

In our problem, initially the spring is uncompressed, so $x_i=0$ . Therefore, the work done by the spring when it is compressed until $x_f$ is
$W=- \frac{1}{2}kx_f^2$
And this value is actually negative, because the box is responsible for the spring's compression, so the work is done by the box.

Why is velocity and not just speed important to these pilots

Alborosie

Velocity is a vector. Therefore, it depends on the direction. Pilots need to know the direction of wind, not just the speed. If the pilot is going South, and there's 5 mph wind going South, they'll be happy, but if the wind is going 5 mph North, they'll be going against the wind.
