Answer:
A) T.
Explanation:
Kepler's third law states that the orbital period (T) of a satellite is related with the radius (R) and the mass of the object (M) it orbits:
So the orbital period is independent of the mass of the satellite, that means no matter the mass every satellite at a radius R around the earth have an orbital period A.
Answer: The period of the pendulum will be bigger than in Earth.
Explanation:
The period of a pendulum is:
T = 2*pi*√(L/g)
where pi = 3.14
L is the length of the pendulum and g is the gravitational acceleration.
you can see that g is in the denominator, so if g is smaller, then the end number woll be bigger (because in the moon we are dividing by a smaller number)
This means that in the moon the period of the pendulum is bigger than in the Earth.
A proton has a positive charge, an electron has a negative charge. Usually, the amount of electrons and protons is the same, but when an electron is lost usually because of radiation or a chemical reaction the resulting amount of electrons/ protons results in a different charge for the atom in general.
When there are more electrons the result it a negative ion, and when there are more protons it is a positive ion.
So, to answer your question: if an electron is lost from a neutral atom and there are more protons than electrons you get a positive charge. Have a good day!
The mass is moving by uniformly accelerated motion, with initial velocity
and acceleration
. Its position at time t is given by the following law:
where we take the initial position
since we are only interested in the distance traveled by the mass.
If we put
into the equation, the corresponding time t is the time it takes for the mass to travel this distance:
And the two solutions for the equation are:
--> negative, we can discard it
--> this is the solution to our problem
