Explanation:
Given that,
The initial velocity of an arrow is 23.4 m/s
We need to find the time taken by it to reach its maximum height. Let the maximum height is h.
Using third equation of motion to find height first.
At maximum height, v = 0
a = -g
Let t is the time to reach its maximum height. So, it can be calculated using second equation motion as follows :
Hence, it will take 2.35 seconds to reach its maximum height.
Answer:
Frequency
Explanation:
A period is the number of revolutions in a minute.
Also, frequency can be defined as number of oscillation per unit time.
Mathematically, frequency is given by the formula;
Thus, we can deduce that frequency of an oscillation is the inverse of the period (time) of oscillation.
Mathematically, period is expressed as;
This ultimately implies that, an object's period of oscillation can always be used to solve for frequency.
Answer:
A fluids is any substance that flows. Air is made of stuff, air particles, that are loosely held together in a gas form. Although liquids are the most commonly recognized fluids, gasses are also fluids. Since air is a gas, it flows and takes the form of its container.
