Answer:

Protons and neutrons are heavy, Electrons are extremely light

Explanation:

Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus.

Which equations represent the relationship between wavelength and frequency for a sound wave? Check all that apply. V = f = vf f

Vikentia [17]

It's really hard to make out the gibberish at the end, where the list of choices should be.

Here are the three equations for the relationships among the wavelength, frequency, and wave-speed, for ANY wave:

-- Speed = (wavelength) x (frequency)

-- Wavelength = (Speed) / (frequency)

-- Frequency = (Speed) / (wavelength)

Notice that you only have to remember any ONE of these. Then you can always get the other ones by multiplying or dividing both sides by the same quantity.

If you want to remember all of them, here are the short forms:

V = L · f

L = V / f

f = V / L

A robot starts from a certain point and moves east for a distance of 5.0 meters, then goes north for 3.0 meters, and then turns

pashok25 [27]

Explanation:

It is given that, a robot starts from a certain point and moves east for a distance of 5.0 meters, then goes north for 3.0 meters, and then turns west for 2.0 meters.

Let east is +x, west is -x north is +y.

When it moves east for a distance of 5.0 meters, it means (5,0)

When it goes north for 3.0 meters, and then turns west for 2.0 meters, it means (0,3) +(-2,0)

(a) x-y coordinates for the resultant vector is (3,3)

(b) The magnitude of the resultant vector for the robot is given by :

$R=\sqrt{3^2+3^2} \\\\R=4.24\ m$

Pepe and Alfredo are resting on an offshore raft after a swim. They estimate that 3.0 m separates a trough and an adjacent crest

Agata [3.3K]

Answer:

The velocity ( $v$ ) of the wave is 3.08 $ms^{-1}$ .

Explanation:

According to the figure, the distance ( $\large{L}$ ) between a trough and its adjacent crest is $\large{L = 3 m}$ . Also the wavelength ( $\large{\lambda}$ ) of the wave is $\large{\lambda = 2L}$ . Pepe and Alfredo count 11 crests to pass the raft in $\large{t}$ = 21.5 s.
