What is occurring when two waves traveling along the same medium meet and cancel each other out?

Physics
1 answer:
liberstina [14]3 years ago
5 0

Answer:

Destructive interference

Explanation:

Destructive interference occurs when two waves traveling along the same medium meet and cancel each other out. The resultant wave has a smaller amplitude than the individual waves. In this case, the maxima of two waves are 180 degrees out of phase.

Hence, the correct option is (A) "destructive interference"

Samantha's teacher asks her to describe motion in one dimension. This type of motion is always
Whitepunk [10]

A motion in one dimension is a type of motion that is always along a straight line and has a constant acceleration.

Motion refers to a change in the location (position) of an object or physical body with respect to a reference point, especially due to the action of an external force.

In Science, the motion of an object or physical body is described in terms of the following parameters:

  • Speed
  • Force
  • Acceleration
  • Distance
  • Time

Furthermore, there are three (3) forms of motion based on dimension and these include:

1. Motion in one dimension

2. Motion in two dimension

3. Motion in three dimension

A motion in one dimension (one-dimensional motion) is also referred to as rectilinear or linear motion. Also, it is always along a straight line in any direction and characterized by constant acceleration.

Do animals fart and do all animals blink and do animals have the same trait of humans
pantera1 [17]
Uh yes they do fart and blink. Like very living person, and animal. They do have the same traits, as that to humans, but their biology is set up differently. They are stronger and quicker.
I'm not going to state that humans are animals, because I don't agree. Humans are NOT animals!!! But that's my belief, oppose as you like.
I think the best way to answer this question, is to imagine being an animal. Possibly a wild animal. What do you do? How do you find food? Where do you sleep? See, usually humans know how to be disgusted about living in unsanitary and unsafe environments. I mean looking at the traits, they're biology is just set up differently from humans.

I hope this helps.<span />

Why do lithospheric plates move constantly?
Charra [1.4K]
I think the correct answer from the choices listed above is option C. Lithospheric plates move constantly due to the density differences. Lithospheric plates<span> are another name for tectonic plates, which are part of the Earth's uppermost layer, the crust.</span>

Professor Stefanovic is spinning a bucket of water by extending his arm and rotating his shoulder in class to show the effects o
anyanavicka [17]

Answer:

a ) 2.368 rad/s

b) 3.617 rad/s

Explanation:

the minimum angular velocity that Prof. Stefanovic needs to spin the bucket for the water not to fall out can be determined by applying force equation in a circular path

i.e

F_{inward } = F_G + F_T   ------ equation (1)

where;

F_{inward} = m *a_c

F_{inward} = m*r* \omega^2

Also

F_G = m*g

F_T = 0          since; that is the initial minimum angular velocity to keep the water in the bucket

Now; we can rewrite our equation as :

mr \omega^2= mg + 0\\\omega^2 = \frac{m*g}{m*r}\\\omega^2 = \frac{g}{r}\\\omega = \sqrt{\frac{g}{r} \ \  }     ------ equation \ \ \ {2}

So; Given that:

The rope that is attached to the bucket is lm long  and his arm is 75 cm long.

we have our radius r = 1 m +  75 cm

= ( 1 + 0.75 ) m

= 1.75 m

g = acceleration due to gravity = 9.81 m/s²

Replacing our values into equation (2) ; we have:

\omega = \sqrt{ \frac{9.81}{1.75}}\\\omega = 2.368 \  rad/s

b) if he detaches the rope and spins the bucket by holding it with his hand ; then the radius = 0.75 m

∴

\omega = \sqrt{ \frac{9.81}{0.75}}\\\omega = 3.617 \  rad/s
