What is the stopping distance of a car? Virtually all current production vehicles’ published road braking performance tests indicate stopping distances from 60 mph that are typically 120 to 140 feet, slightly less than half of the projected safety distances. How does speed affect reaction distance? As a vehicle’s speed increases, so does the distance […]

What is nervous system answer? The nervous system controls everything you do, including breathing, walking, thinking, and feeling. This system is made up of your brain, spinal cord, and all the nerves of your body. The nerves carry the messages to and from the body, so the brain can interpret them and take action. Why […]

Which has largest diameter? Large objects in our solar system Largest planet: Jupiter, roughly 88,846 miles (142,984 km) at its largest diameter, which is about 11 times the diameter of the Earth. What is the diameter of Earth? 12,742 km How do we measure the size of the Earth? It was generally agreed upon that measuring […]

What changes wave period? The wave period is also dependent on the wavelength and the velocity. The higher the velocity, the lower the wave period, and the higher the wavelength, the higher the wave period. Do swell waves break? When swell finally reaches shallow water- whether that be a continental shelf, a reef system, or […]

What happens to yeast in warm water? When the warm water hits the yeast, it reactivates it and “wakes it up.” Then it begins to eat and multiply. The yeast organism feeds on the simple sugars found in flour. As they feed, they release chemicals and gases like carbon dioxide and ethanol, along with energy […]

Can you see Venus in the sky? Venus ranks as the third-brightest celestial object to light up the sky, after the sun and moon, so you have a good chance of spotting Venus 1/2 hour or sooner after sundown. How much is Queen of the Night flower? Compare with similar items This item QUEEN OF […]

How do you calculate drop height? Example 2: An object is dropped from a height of 120 feet. If h is measured in feet, t is the number of seconds the object had fallen, and h0 is the initial height from which the object was dropped, then the model for the height of falling object […]

What determines the color of a main sequence star? Temperature translates to color, and this relationship between color and brightness (luminosity) for hydrogen-burning stars is called the main sequence. Massive hydrogen-burning stars are blue-white, the Sun is yellow, and low-mass stars are orange and red. What is the primary reason for the star evolution? The […]
