A physical property can be seen or a change in color.
The answer is B because you can see when wood is rotting.
Answer:
Explanation:
The electric force between two charged objects is given by:
where:
k is the Coulomb's constant
q1 and q2 are the charges of the two objects
r is their separation
In this problem:
q1 = 2.0 C
q2 = 1.0 C
r = 2 m
So, the electric force is
V = p / m
V = 1000 / 2.5
V = 400 m/s
hope this helps!
Answer:
how its outward appearance is changing
Explanation:
H-R diagram is a fundamental tool used to classify stars. The position of stars on the H-R diagram is dependent on its luminosity and temperature.
The position of the star is represented by its outward appearance specially the color. The hottest and brightest the star, the more it lies between the red and blue color range.
The cooler stars lie on the right side of the H-R diagram while the hot stars lie on the left side of the H-R diagram.
Answer:
true
explanations: especially hot body ie.above -273 tends to emit infrared type radiation
