Answer:
D. During the day, air over the warm land heats up and rises, while cooler air that was over the water is drawn in to shore to replace it.
Explanation:
Convection creates wind patterns at a beach by the force of land and sea breeze which are different wind patterns that move air masses.
Convection is a form of heat transfer that occur mainly in fluids such as gases and in liquids.
During the day, the air over the land is warmed. The land is a good conductor heat better than the ocean. This air masses rises and move towards the ocean. The colder air from the ocean moves landward to replace this air mass.
As the cold air gets warmer at land, it rises and move ocean-ward again.
If a crane uses 500 Joules to raise bricks 20 meters how much Newton’s of force were used
Answer:
25N
Explanation:
Given parameters:
Potential energy expended = 500J
Height = 20m
Unknown:
The force used = ?
Solution:
To solve this problem, we use the expression below:
Potential energy = Force applied x height
500 = Force applied x 20
Force applied = 25N
What is ONE variable that will change the amount of POTENTIAL ENERGY
of a box on the floor?
Answer:
The height or the mass
Explanation:
The one variable that can change the potential energy of a box on the floor is either the height or the mass of the box.
Potential energy is the energy due to the position of a body.
Mathematically;
Potential energy = mass x acceleration due to gravity x height
Therefore, if the mass of the box is changed, the potential energy changes also.
If the position of the box is changed by raising it up, the potential energy changes

If I stretch a standard rubber band (mass of 0.01 kg, spring constant of 40 N/m) 0.25 meters, how high would it launch into the air?
Answer:
You have a hooks law problem F=kx Where F= (40 N/m)× (0.25 meters) F= 10 N Hence the force is 10 NAnswer: The answer would be 12.5 m
Which color of visible light has a shorter wavelength than blue light? O A. Red O B. Green O C. Violet OD. Orange A
Answer:
It's violet........
Explanation:
This was right for me.
The color of visible light that has a shorter wavelength than blue light is Red. The correct option is A.
What is electromagnetic spectrum?The electromagnetic spectrum consists of the range of all types of EM radiation. Radiation is packet of energy that travels and spreads out. It has radio waves, infrared waves and visible light waves, ultraviolet rays and microwaves.
They possess high energy even to penetrate deep within the material. electromagnetic spectrum ranges from longer wavelength and less frequency to shorter wavelength and high frequency.
The light with higher wavelength is Blue and the shorter wavelength is Red and the rest of all spectrum colors are in between.
Thus, the correct option is A.
