When an object with a negative charge is moved from point A to point B through an external electrical field, it gains electrical

Sergio039 [100]

Explanation:

As per the problem,

$\Delta U = (V_{B} - V_{A})(-q) > 0$

When q > 0 then -q is a negative charge . Since, change in potential energy ( $\Delta U$ ) increases.

or, $(V_{A} - V_{B})q$ > 0

or, $V_{A} > V_{B}$

Therefore, both positive and negative charge will move from $V_{A}$ to $V_{B}$ and as $V_{B} < V_{A}$ so both of them move through a negative potential difference.

Thus, we can conclude that the true statements are as follows.

The positively charged object moves through a negative potential difference between A and B (that is, VB - VA < 0).

The negatively charged object moves through a negative potential difference between A and B (that is, VB - VA < 0).

If it were possible to move a star towards the earth then its apparent magnitude number would ______ while its absolute magnitud

ArbitrLikvidat [17]

If it were possible to move a star towards the earth then its apparent magnitude number would decrease while its absolute magnitude number would stay the same.

Definition of apparent magnitude:

The luminosity of a celestial body (such as a star) as observed from the earth compare absolute magnitude.

So for example, the apparent magnitude of the Sun is -26.7 and is the brightest celestial object we can see from Earth. However, if the Sun were 10 parsecs away, its apparent magnitude would be +4.7, only about as bright as Ganymede appears to us on Earth.

Definition of absolute magnitude:

Absolute magnitude is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale.

Answer:

c. 2 m/s

Explanation:

The speed of a wave is given by:

$v=f \lambda$

where

v is the speed of the wave

f is the frequency

$\lambda$ is the wavelength

For the wave in this problem, we have

f = 4 Hz is the frequency

$\lambda = 0.5 m$ is the wavelength

So, the speed of the wave is

$v=(4 Hz)(0.5 m)=2 m/s$
