Answer:
"h" signifies Planck's constant
Explanation:
In the equation energy E = h X v
The "h" there signifies Planck's constant
Planck's constant is a value, that shows the rate at which the energy of a photon increases/decreases, as the frequency of its electromagnetic wave changes.
It was named after Max Planck who discovered this unique relationship between the energy of a light wave and its frequency.
Planck's constant, "h" is usually expressed in Joules second
Planck's constant = 
Forces on a Baseball. When a baseballis thrown or hit, the resulting motion of the ball is determined by Newton's laws of motion. ... Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.
Answer:
Frequency change by a factor of 2.
(b) is correct option.
Explanation:
Given that,
Mass = 16 kg
Replaced mass = 4 kg
We need to calculate the frequency
Using formula of frequency
Put the value into the formula
....(I)
...(II)
Hence, Frequency change by a factor of 2.
The state of matter which has the most orderly arrangement is solid. Here is the order of the three basic states of matter arranged from fastest to slowest, it's better to memorize it :<span>gas, liquid, solid. Also, remember that the colder your solid is, the more ordered it is.</span>
More
because the faster it moves the more energy it picks up
