The AU ... Astronomical Unit ... used to be defined as the average distance between the Sun and Earth during the year.
Now it's defined as 149,597,870,700 meters exactly.
The correct answer should be polygenic inheritance
Most genes that affect the way a human being looks have been inherited in this way. Not only hair but also things like height and weight, eye color, and similar.
A law stating that electric current is proportional to voltage and inversely proportional to resistance.
Answer:
0.702 m
Explanation:
The magnitude of the electrostatic force between two charged objects is given by Coulomb's Law:
where
k is the Coulomb's constant
q1, q2 are the two charges
r is the separation between the objects
And the force is:
- Attractive if the two charges have opposite signs (+-)
- Repulsive if the two charges have same sign (++ or --)
In this problem we have:
is the force between the two balls
is the charge on each ball
Solving for r, we find the separation between the balls:
<span>the sun raises the temperatures of molecules inside the balloon. As the molecules receives more kinetic energy, they move apart from each other and expand in volume. Depend on the balloon's material, it might not be strong enough to handle the pressure exerted by the gas inside, and the balloon will pop.</span>
