Imagine that you and your friend are at the beach. You have your chairs and umbrella set up in the perfect spot near the water so you can jump in to cool off with ease. A few hours into your stay, the water line has managed to creep up closer and closer to your chairs and your things start to get wet! Your friend points up at the Moon and says it is to blame. What does this mean? Write a response in complete sentences. I NEED A ANSWER PLZZZZZ! And this is a science question.
Answer:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. ... When you're not in one of the bulges, you experience a low tide.

3.How are climate and weather different?
4.How can you depict annual precipitation at a site location, like a local airport?
5. What is the transformation of water vapor to liquid water droplets in the air?
Climate is different from the weather. Climate is the long term weather condition and weather is short term atmospheric condition. The annual precipitation is report is depicted as graphical data. Transformation of water vapor to liquid droplets in air is called condensation.
What is climate?Climate in a region is the long term weather exists there and which will be characteristic for that region. Weather is forecasted for a day or a particular time, reporting the short term atmospheric condition. Climate of a locality depends on the landscape there, local winds etc.
The annual precipitation report determined by the summation of monthly precipitation data and which in turn obtained by the summation daily precipitation for each month and it is depicted graphically to analyse.
The transformation of water vapor to liquid droplets in the air is called condensation. The gaseous molecules of the water vapor condense together to form the liquid droplets.

Which type of electromagnetic energy must be used carefully in medicine so it does not damage living tissue?(1 point)
low frequency waves
visible light
radio waves
gamma rays
Among electromagnetic waves, UV rays are most dangerous because exposure to these radiation cause serious problems in living organism. Therefore, gamma rays is used carefully in medicine without damaging living tissue.
What is electromagnetic wave?Electromagnetic wave is a wave which contain two component one is electric component and other is magnetic component. The electric and magnetic component are perpendicular to each other. There are so many wave that comes under electromagnetic wave like infrared wave , radio wave.
There is a relation between energy of wave. frequency of wave, and wavelength of wave
Mathematically,
E=hc/λ
where,
E = energy of electromagnetic wave
h is planks constant having value 6.67×10⁻³⁴js
c is speed of light that is 3×10⁸m/s
λ is the wavelength of electromagnetic wave
There are many uses of electromagnetic radiations in medical field. Gamma rays are used to kill the dead cells from e.g. cancer but they don’t destroy the living cells as gamma is only a wave.
Therefore, gamma rays is used carefully in medicine without damaging living tissue.

Cu (reactant)= 1
S (reactant)= 1
Fe (product)= 1
O (product)= 4
Explanation:
The answer is quite simple, look at each element and see if there is an attached number at the end. O4= 4 oxygen atoms O3= 3 oxygen atoms. You see the pattern?
Also if there is no such number attached to the element, assume there is one atom.
