Answer:

Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.

VARVARA [1.3K]

In a series circuit, each circuit element has the same current. The answer is letter A. This is because the electrons flowing in a current has only a single path to follow. There are no other path that the current moves along.

Answer:

It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.

What can we say about a polarizing filter with vertically aligned chemical molecules?

klemol [59]

Answer:

A . It will allow vertically polarized light to pass through it.

Explanation:

Polarization is the attribute in which waves oscillate in a particular direction relative to the direction of travel. The direction of polarization determines the type of polarized light produced. Since the chemical molecules are vertically aligned, it will only allow vertically polarized light pass through it.

To understand the relationships between the parameters that characterize a wave. It is of fundamental importance in many areas o

Monica [59]

Answer:

1) c.

2) a.)

Explanation:

At any wave, if its waveform repeats itself every time interval T, it is said that the wave is periodic, with a period T, which is the time needed to complete an entire cycle. The other options refer at the way in the waves propagates (longitudinal or transversal) and to the type of waveform (sinusoidal), so the right answer is c).

At any wave that propagates at a constant speed, there exists a fixed relationship between the velocity v, the frequency f and the wavelength λ, as follows:

$v = \lambda * f (1)$

So in order to v keep constant, if the frequency is increased, the wavelength will decrease in the same proportion, so a) is the right answer.
