We need to directly measure the spectral type in order to determine the surface temperature of a star.
<h3>How do you find the properties of a star?</h3>
Astronomers can determine the temperature of a star by looking at its color and spectrum. The apparent brightness of a star describes how luminous it looks to us. The brightness of a star tells us how bright it really is. The luminance can be determined using both the perceived brightness and the distance.
A star's luminosity, or the total amount of energy it emits each second, is determined by two factors: The stellar photosphere's "Effective Temperature," T. the star's total surface area, which is influenced by its radius, R.
Because it controls how much fuel a star has and how quickly it burns it, a star's mass is its most fundamental characteristic. The majority of a star's life is spent burning hydrogen into helium in its core, which generates energy. The star needs to achieve a balance between gravity and outward pressure in order to continue to be "alive."

<h2>
Time taken is 0.459 seconds</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 0 m/s
Final velocity, v = 81 km/hr = 22.5 m/s
Time, t = ?
Acceleration, a = 49 m/s²
Substituting
v = u + at
22.5 = 0 + 49 x t
t = 0.459 seconds
Time taken is 0.459 seconds
The element is a resistor, so some of the electrical energy flowing through the heating element is converted to thermal energy.
Answer:
Another metaphor that can help explain energy quantization at the atomic level is the number of teams at different stages in the Football World Cup tournament taking each stage as a given amount of energy gained by the teams at that stage as follows;
Stage 1 Group Stage
The number of teams in the group stage = 32, Energy per team = 1
Knock out stages
Round of 16
The number of teams in the round of 16 stage = 16, Energy per team = 2
Semi final
The number of teams in the semi final stage = 8, Energy per team = 4
Quarter final
The number of teams in the quarter final stage = 4, Energy per team = 8
Final
The number of teams in the semi final stage = 2, Energy per team = 16
The winning team
The number of teams that win the World Cup = 1, Energy of the team = 32
As seen as each team has a specific energy level at each stage of the world cup and there can not any energy value that is an intermediate value of the energy of the teams each at each stage, so also at the atomic level particles within the atom and therefore the atom itself can possess only specific quantum of energy values in a given level or state.
