When t=2, the ball has fallen d(2) = 16 (2²) = 64 feet .
When t=5, the ball has fallen d(5) = 16 (5²) = 400 feet .
Distance fallen from t=2 until t=5 is (400 - 64) = 336 feet.
Time period between t=2 until t=5 is (5 - 2) = 3 seconds.
Average speed of the ball from t=2 until t=5 is
(distance covered) / (time to cover the distance)
= 336 feet / 3 seconds = 112 feet per second.
That's what choice-C says.
1. Nuggets (AKA: Sonic Ice)
Nugget-shaped ice tends to be soft and chewy. One of the benefits to this type of ice is that the drink it is mixed with tends to keep its flavor well. This makes nugget ice great for food service. The nuggets tend to not stick together and lasts for a good amount of time in any drink.
Nugget ice is the ideal choice for carbonated drinks and blended cocktails, but also works great in salad bars and produce displays to keep food cool.
2. Flakes
You might be familiar with ice flakes as they are often found in snow cones. Not only does this ice look good, but it also serves well to preserve food on display, such as seafood, meat, and produce.
Ice flakes are great for display because they help to maintain the hydration of the food more consistently for longer periods of time. For this reason, it is also a good ice shape choice for transporting perishable food. This is also the ideal ice type for making blended drinks, as the ice is soft, flaky and easier to blend.
Answer:
3.2m
Explanation:
Given parameters:
Frequency of the FM radio = 9.23 x 10⁷Hz
Velocity of the waves = 3 x 10⁸m/s
Unknown:
Wavelength of the wave = ?
Solution:
To solve for the wavelength of the wave, we need the velocity equation;
Velocity = frequency x wavelength.
Radio waves are all electromagnetic radiations produced by both electrical and magnetic fields perpendicularly oriented to one another.
Since the unknown is wavelength, we solve for it:
3 x 10⁸ = 9.23 x 10⁷ x wavelength
wavelength = 
wavelength = 3.2m
Observational studies are a prime example. Observational data is more reflective of the real environments that scientists make their inferences to than controlled experiments. The disadvantage of observational studies is that the variability is far greater. <span />
Answer: 
Explanation:
The frequency 
of an electromagnetic wave is given by the following equation:
Where:
