Do more spokes make a wheel stronger? Also spokes need to be stronger, thicker (and heavier). Wheels with 36 and more spokes can carry more load, are more durable and easier to (keep) true. Even in case a spoke breaks, they don’t come out of true very much and can get a rider home. 40 […]
What causes the oceans to bulge?
What causes the oceans to bulge? Gravity and inertia act in opposition on the Earth’s oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean’s waters toward it, creating one bulge. What are the […]
What can radio waves do to the body?
What can radio waves do to the body? RF radiation has lower energy than some other types of non-ionizing radiation, like visible light and infrared, but it has higher energy than extremely low-frequency (ELF) radiation. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to […]
How can a hydrogen atom which has only one electron have so many spectral lines Group of answer choices?
How can a hydrogen atom which has only one electron have so many spectral lines Group of answer choices? Though a hydrogen atom has only one electron, it contains a large number of shells, so when this single electron jumps from one shell to another, a photon is emitted, and the energy difference of the […]
What is the difference between a sequence valve and a priority valve?
What is the difference between a sequence valve and a priority valve? In order to operate the secondary unit, the fluid must flow through the sequence valve. The valve is located so that the primary unit moves the plunger as it completes its operation. If the pressure drops below 2,200 psi, the priority valve closes […]
What are 5 animals that cause biological weathering?
What are 5 animals that cause biological weathering? Burrowing animals like shrews, moles, earthworms, and even ants contribute to biological weathering. In particular, these animals create holes on the ground by excavation and move the rock fragments to the surface. How do plants and animals help weather rocks and soil? – weathering breaks down rocks […]
Which information can be determined using half life quizlet?
Which information can be determined using half life quizlet? A rock’s size is determined by half-life. All stable and unstable elements have a half-life. An atom of an element becomes half its original size in a half-life. A half-life is the time required for half of a radioactive element to decay. What is meant by […]
Is sandstone a rough?
Is sandstone a rough? Sandstone. Sandstones are made of sand grains that have been cemented together. Like sandpaper, sandstones usually have a rough, granular texture, but to really identify a sandstone you have to peer closely at its surface and look for individual sand grains. You can just make out the grainy texture of the […]
What is the best material for a homemade parachute?
What is the best material for a homemade parachute? Nylon fabric for parachutes is woven in a specialized manner with extra thick threads to create a pattern of small squares – this is known as ripstop nylon. When small tears occur in the canopy, these small squares prevent the tears from becoming bigger. Does a […]
Why is VO2 max dropping?
Why is VO2 max dropping? A V02 decrease during a training program sounds like overtraining. One of the symptom is the augmentation of tour your heart rate. At early stage of overtraining, you won’t physically notice it or feel it but things like V02 go down, resting heart rate go up… What is the fastest […]
