u= 215 km/hr = 215 * 1000/ 3600 = aprx 60m/s
v=0
t=2.7sec
v= u - at
u= at
60/2.7 = 22.23 m/s^2
Hope it helps
Answer: A.The ocean is colder than the land
Explanation:
Based on the information provided in the question, we are informed that Agustin visits Panama City, Florida, during the month of May and that he feels a shore breeze blowing from the ocean onto the beach.
The reason for the shore breeze is simply due to the fact that the ocean is colder than the land. Since the ocean is colder, anyone who goes to the beach will feel the breeze.
Answer:
negative ion
Explanation:
An atom that has fewer neutrons than protons and more electrons than protons is a negative ion.
The positively charged particles in an atom are the protons
The negatively charged particles in an atom are the electrons.
The charge an atom carries depends on the balance between the number of protons and electrons in an atom.
- When the number of protons is more than the number of electrons, the atom is positively charged.
- When the number of electrons is more than the number of protons, the atom is negatively charged.
Answer:
429 m
Explanation:
In this exercise you are suppose to simulate a right triangle, the catheti are the distance you walked and the height of the empire state building.
tan(88) = (height) /(distance you walked)
28.64 = height / 15
height = 429 m
The frequency of any wave is (wave speed) / (wavelength) .
The speed of light is 3 x 10⁸ m/s.
If the wavelength is 10 nm (10⁻⁸ m) , then the frequency is
(3 x 10⁸) / (10⁻⁸) = <em>3 x 10¹⁶ Hz</em>
That's 30 million gigahertz !
