Rubber. The other three are metals, and therefore good conductors.
A hurricane becomes more powerful by evaporating water from oceans
Answer:
L=55.9m
Explanation:
The equation for the period of a simple pendulum is:
In our case what we know is the period and the acceleration of gravity, and we need to know the length of the pendulum, so we can write:
Which for our values is:
The correct answer is A. Each object in the universe that has mass attracts every other object that has mass.
Explanation:
The gravitational law proposed by Newton explains how the gravitational force works. The basic idea or premise in this law is that the gravitational law exists in all the universe, and occurs with all objects that have a mass. This includes the fact all objects or particles that have a mass attract all other objects with mass but this is also influenced by the distance between the objects, and the masses of each object. In this way, the gravitational force is equal to the gravitational constant multiplied by the mass of the two objects and divided by the distance between the objects.
