Use Kepler's third law to find the planet's average distance (semimajor axis) from its star. (Hint: Because the mass of the star
is about the same as the mass of our Sun, you can use Kepler's third law in its original form, p2)
1 answer:
Answer:
Explanation: The planet average distance = 42300km
Kepler's 3rd Law also known as the Harmonic Law states that;
for each planet orbitting the sun, its side real period squared divided by the cube of the semi-major axis of the orbit is a constant.
A planet, mass m, orbits the sun, mass M, in a circle of radius r and a period t. The net force on the planet is a centripetal force, and is caused the force of gravity between the sun and the planet.

Answer:
We can increase the strength by increasing current in the wire or increasing the number of turns of the coil around an iron core .
Explanation:
The magnetic strength due to current carrying conductor carrying current I and having N number of turns is given by
B =
is vacuum permeability .and its value is equal to
.so from the above equation we can see that magnetic strength is directly proportional to the current through wire and no. of turns .
Answer:
Explanation:
Given that,
The work function for silver is 4.73 eV.
We need to find the value of the work function from electron volts to joules.
We know that,
For 4.73 eV,
So, the work function for silver is .
