Can a nuke make a volcano erupt? On an already active volcano, or one that is just about to blow, a nuclear bomb might alter the lava flow, or cause it to erupt a little sooner. What happens if you drop a nuke in a hurricane? Nuclear fallout would spread Exposure to too much of […]

Does work input equal work output? Work output is always less than work input, so an actual machine cannot be 100% efficient. The effort force is the force applied to a machine. Work input is the work done on a machine. The work input of a machine is equal to the effort force times the […]

What density do you need to float? Students should realize that if an object weighs more than an equal volume of water, it is more dense and will sink, and if it weighs less than an equal volume of water, it is less dense and will float. Remember that the density of water is about […]

The nervous system uses both electrical and chemical means to send and receive messages. Who discovered the nervous system? Herophilus Who named Nerves? […]

What are the five basic plant processes? Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations. What are the two critical processes of leaves? photosynthesis. Water and carbon dioxide […]

What is it called when waves overlap? Wave interference is the interaction of waves with other waves. Constructive interference occurs when the crests of one wave overlap the crests of the other wave, causing an increase in wave amplitude. Is the number of waves that move past one spot in a second? Wave frequency is […]

Is a windmill a wheel and axle? The model wind turbine in this activity more closely represents a windmill. This model is a simple machine, specifically a wheel and axle. The wind blows on the blades (the paper wheel), which turns the axle (the straw). What class lever is a pizza cutter? third class What […]

What are the 3 calcium regulating hormones? Three calcium-regulating hormones play an important role in producing healthy bone: 1) parathyroid hormone or PTH, which maintains the level of calcium and stimulates both resorption and formation of bone; 2) calcitriol, the hormone derived from vitamin D, which stimulates the intestines to absorb enough calcium and … […]
