Which type of star has surface temperatures bewteen 2400 and 50000 k

Nady [450]

Hi!

We call these stars <em>main sequence </em>stars. Main sequence stars actually make up around 90% of the stars in our universe!

An interesting thing to note is that our sun is actually a <em />yellow dwarf star, which is a <em>small </em>main sequence star.

Hopefully, this helps! =)

Leni [432]

Answer:

a.Electric force exerted on one charged sphere, by another charged sphere.

Explanation:

Coulomb's Law describes the electric force between two objects. It is given by the following formula:

$\vec{F} = \frac{1}{4\pi\epsilon_0}\frac{q_1q_2}{r^2}\^r$

The magnetic field surrounding a current carrying conductor is described by Ampere's Law.

Amount of heat generated by a high current flow in a resistor can be described by P = VI

Voltage induced in a coil by a constant magnetic field is described by Faraday's Law.

Two charge spears are 20 cm apart and extract an attractive force of 8x10^-9 N on each other. Which will be the force of attract

Talja [164]

Answer:

3.2 × 10⁻⁸ N.

Explanation:

By Coulomb's Law, the magnitude of the electromagnetic force between two point charges is inversely proportional to the square of their separation, $r$ . In other words,

$\displaystyle \frac{F_1}{F_2} = {\left(\frac{r_2}{r_1}\right)}^{2}$ .

Initial electromagnetic force $F_1 = 8\times 10^{-9}\;\text{N}$ ;
Initial Separation $r_1 = 20\;\text{cm}$ ;
Final Separation $r_2 = 10\;\text{cm}$ .

Final electromagnetic force:

$\displaystyle F_2 = F_1 \cdot \left(\frac{r_2}{r_1}\right)^{2} = 8\times 10^{-9}\times \left( \frac{20}{10}\right)^{2} = 3.2\times 10^{-8}\;\text{N}$ .

A 5.0 kg wooden block Is 100 meters from the ground. What is the gravitational potential energy for the block?

iren [92.7K]

Answer:

Explanation:

The gravitational potential energy of a body can be found by using the formula

GPE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

GPE = 5 × 9.8 × 100

We have the final answer as

Hope this helps you
