What happens when the bat hits the ball? When the bat hits the ball, the ball goes flying. A lot happens in that split second, as energy is transferred from the player to the bat, and then to the ball. What is it called when you hit the ball out of the park and can […]

How do you find speed when given height? Multiply the height by the object’s acceleration due to gravity. The acceleration due to gravity is 32.2 ft/s^2 for English units, or 9.8 m/s^2 for SI units. If you drop an object from 15 feet, for example, you would multiply 15 ft * 32.2 ft/s^2 to get […]

What questions does epistemology ask? Epistemology asks questions like: “What is knowledge?”, “How is knowledge acquired?”, “What do people know?”, “What are the necessary and sufficient conditions of knowledge?”, “What is its structure, and what are its limits?”, “What makes justified beliefs justified?”, “How we are to understand the concept of … What is epistemology […]

How do you solve Hardy-Weinberg equilibrium problems? Step 1: Assign the Alleles. • By convention, we use the dominant phenotype to name the alleles. Step 2: Calculate q. The number of homozygous recessive individuals is q. Step 3: Calculate p. Once you have q, finding p is easy! Step 4: Use p and q to […]

Does photosynthesis release energy from glucose? Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Does glycolysis release energy from glucose? Glycolysis produces 2 ATP, 2 NADH, […]

Do horses run faster on dirt or turf? Grass is a more slippery surface than dirt and harder too when dried. But it is also easier on a horse’s feet and leg because of the cushion underneath their feet. But it is also a much faster surface and speed horses tends to run faster than […]

How fast does sound travel if the air temperature is 20 C? about 343 metres per second What is the speed of sound in air at 150 C? At a temperature of 819.45, we get a speed of sound of 662.6 m/s. Does sound travel faster or slower as temperature increases? Therefore, sound travels faster […]
