Answer:
The star's luminosity rises above its previous level. Because it is so cool, the surface will be red, and it will be much farther away from the center than it was during the earlier stages of star evolution. Despite its lower surface temperature, the red giant has a large surface area, which makes it very luminous.
Answer:
184 Km
Explanation:
given,
speed of S wave = 4.50 Km/s
speed of P wave = 7.80 Km/s
reading time difference = 17.3 s
we know,
distance = speed x time
time taken by s-wave
time taken by the P-wave
now,
t₁ - t₂ = 17.3 s
3.3 x = 607.23
x = 184 Km
distance of the focus from the station is 184 Km.
Answer:
0.50 A
Explanation:
We can find the current from this through Ohm's Law:
V = IR
Now, in it's original form, we're only looking for Voltage. However, we can switch this formula around to find each part of it:
I = V / R <em>(current)</em>
R = V / I <em>(resistance)</em>
In this case, we'll use the formula for current:
V = 120 V
R = 240 Ω
I = ?
I = 120 / 240
<u><em>I = 0.5 A</em></u>
