The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
A quarterback throws a football toward a receiver from a height of 6 ft. The initial vertical velocity of the ball is 14 ft/s. At the same time that the ball is thrown, the receiver raises his hands to a height of 8 ft and jumps up with an initial vertical velocity of 10 ft/s.
The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8

Answer:
In uniform circular motion, the speed remains constant while the direction of the object changes. This means the object experiences an acceleration toward the center of the circle, which is known as centripetal acceleration.

Answer:
Taking into account the definition of avogadro's number, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
First, you have to know that it is called Avogadro's Number or Avogadro's Constant. By Avogadro's number it is understood the number of elementary entities (that is, of atoms, electrons, ions, molecules) that exist in a mole of any substance. Its value is 6.023×10²³ particles per mole.
Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression.
Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023×10²³ atoms are contained in 1 mole of silver, then 1.8×10²⁰ atoms are contained in how many moles of silver?
amount of moles of silver= (1.8×10²⁰ atoms × 1 mole)÷ 6.023×10²³ atoms
amount of moles of silver= 2.98×10⁻⁴ moles
Finally, 1.8×10²⁰ atoms of silver are in 2.98×10⁻⁴ moles of silver.
