Which wave would have more energy a small wave or a large wave?
Twentynine
I suppose you're talking about small wavelenght or large wavelength. In this case, the answer is that a wave with lower wavelenght has more energy than a wave with higher wavelenght.
You have to consider that the energy associated to an electromagnetic wave is, according to de Broglie:
E = hf
where h is the Planck constant (which is, more or less, h = 6.626·10-34 Js) and f is the frequency of the wave. The relationship between frequency and wavelenght is given by
f = c/lambda
where c is the speed of light and lambda the wavelenght. So finally you have
E = hc/lambda
According to this equation, the higher the wavelenght, the lower the energy.

Would a large earthquake cause more damage than a small earthquake?
yes
Is selecting map projection more important for small scale or large scale maps?
small scale
How does a person's level of physical activity affect his or her daily energy needs?
If a person exercises for 2-3 hours a day, he would require more energy compared to a guy who doesn't exercise. This is because. the more exercise/physical activity you do, the increased amount of energy you use. Therefore, your body would need to replenish that used energy. This is done by increasing his/hers daily energy needs. A person who doesn't exercise would have a lower energy need as they don't use that much energy compared to an athlete.
Would a map that covers a large area have the same map scale as a map that covers a small region how would the scales deffer?
It could have, but the map of the small region would be very small. The map of the large area would more likely have a larger scale so that more area is covered on the same map area, but in doing so, it will be less detailed than the map of the smaller area with the smaller scale. A larger scale has many more cm in the real world equals 1 cm on the map than a smaller scale one. eg a map for walking could use 1:25,000 (1 cm = 25,000 cm → 1 cm = 0.25 km) whereas the "map" of a room would more likely use a smaller scale of 1:50 (1 cm = 50 cm → 1 cm = 0.5 m)
Why would an artist using oil paint be more inclined to include small details than an artist painting a fresco?
Two possible reasons: Oil paint on a smooth surface makes for easier painting small details than fresco paint on a wall. A fresco is usually a large-format mural, intended to be seen from a distance.
Would a small wave or a large wave have more energy?
a large wave because it is built and its structure is stronger.
Is a small or large breed of dog more sociable?
easy, small. because they have more energy!!
Does a small or a large balloon have more thermal energy?
I really don't know

Does a small balloon or a large balloon have more thermal energy?
I really don't know
Which has more thermal energy, a small cup of hot tea at 75 degrees Celsius or a large cup of hot coffee at 75 degrees Celsius?
the large one of course. because the more the mass is, the more the energy is.
What is more powerful a tornado or nuclear bomb?
An atomic bomb has more destructive potential, but a large, long-lived tornado would probably release more energy than a small nuclear weapon.
Which has more kinetic energy- A small object or a large object moving at the speed of 25 mph?
You don't say what speed the small object has. If both have the same speed then the heavier one will have more kinetic energy.
Which has more thermal energy a large pot of boiling water or a small pot of boiling water?
Yes, if they are the same temperature. The larger bowl would have more mass thus more energy available.
What has more kinetic energy a large dog sitting on a sidewalk or a small cat running down the street?
the large dog since it has mroe mass
Why does a wave with a large amplitude carry more energy than one with small amplitude?
It is the same as why an object at higher place had more energy than one on the floor. Energy is the difference of potential, for kinetic energy example it is the height, greater height is greater energy. For the wave, energy could be stored in amplitude and frequency. Low amplitude or no amplitude is no energy and any amplitude higher than the zero amplitude would have more energy.
