How many deaths have self-driving cars caused? How many deaths have self-driving cars caused? (Gasgoo) So far, there have been two pedestrian fatalities. One was caused by an Uber vehicle, and the other by a Tesla AV. Additionally, four AV drivers died in self-driving car accidents. Has a self-driving car killed anyone? Uber chose not […]
How did alchemists contribute to science?
How did alchemists contribute to science? Through the span of several millennia, alchemists “were learning fundamental principles of chemistry: breaking down ores, dissolving metals with acids, and precipitating metals out of solution [8].” This laid the foundations of basic scientific experimentation with modern alchemists such as Boyle emphasizing the … What were some contributions of […]
What is the difference between closed head injury and concussion?
What is the difference between closed head injury and concussion? A concussion is a type of closed head injury, which is often referred to as a traumatic brain injury or TBI. The symptoms of concussion include headache, dizziness, sleep disturbances, visual changes, difficulty with balance, fatigue and memory problems. TBI encompasses many more brain injuries […]
Why was the plum pudding model wrong?
Why was the plum pudding model wrong? He argued that the plum pudding model was incorrect. The symmetrical distribution of charge would allow all the α particles to pass through with no deflection. Rutherford proposed that the atom is mostly empty space. The atom now consisted of a positive nucleus with negative electrons in circular […]
Which fruit is good for metabolism?
Which fruit is good for metabolism? Watermelon, cantaloupe, honeydew—these are naturally good for metabolism. Watermelon may even help with weight loss because it contains the amino acid arginine, which was found in a study of obese mice to reduce body fat gains by 64 percent. How do I know what my metabolism is? A metabolic […]
When a cannonball is fired from a cannon?
When a cannonball is fired from a cannon? This is called the principle of conservation of momentum . Momentum is conserved in collisions and explosions . Conservation of momentum explains why a gun or cannon recoils backwards when it is fired. When a cannon is fired, the cannon ball gains forward momentum and the cannon […]
How can you tell which star cluster is older?
How can you tell which star cluster is older? By determining the mass of the main-sequence turnoff stars, we get the age of the cluster. The cluster age equals the main-sequence lifetime of the turnoff stars. This is one of the ways we have studied the age of the Universe and the formation history of […]
Why is latitude 180 degrees?
Why is latitude 180 degrees? “Longitude” goes 360 degrees, 180 East to 180 West, to cover the entire 360 degrees around the equator. But if latitude did the same thing, every point on the earth would be covered twice! So latitude only has to cover 180 degrees, from the north pole to the south pole. […]
How much heat is required to raise the temperature?
How much heat is required to raise the temperature? To calculate the energy required to raise the temperature of any given substance, here’s what you require: The mass of the material, m. The temperature change that occurs, ΔT. The specific heat capacity of the material, c (which you can look up). Here is a source […]
