What do we call the bright sphere shaped region of stars that lie within a few thousand light years of the center of the Milky Way galaxy? Bulge and Halo Stars: What do we call the bright, sphere-shaped region of stars that lie within a few thousand light-years of the center of the Milky Way […]
How can we make an object accelerate more?
How can we make an object accelerate more? At that time, you will learn that the acceleration of an object is directly proportional to force and inversely proportional to mass. Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. How can you represent both speed and direction of an object? Summary […]
What is the principle of ultrasound?
What is the principle of ultrasound? An electric current passes through a cable to the transducer and is applied to the crystals, causing them to deform and vibrate. This vibration produces the ultrasound beam. The frequency of the ultrasound waves produced is predetermined by the crystals in the transducer. What is bandwidth in ultrasound? The […]
What is electricity called?
What is electricity called? Electricity is the presence and flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best-known form is the flow of electrons through conductors such as copper wires. The word “electricity” is sometimes used to mean “electrical energy”. Who found the […]
What 3 things are needed for photosynthesis?
What 3 things are needed for photosynthesis? This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. What are the three end products of photosynthesis? Glucose and oxygen are the final products of photosynthesis. We all know […]
How did the reintroduction of wolves affect the elk population Why do you think this happened?
How did the reintroduction of wolves affect the elk population Why do you think this happened? Data as of July 10, 2016. Today, nearly 25 years after wolves were reintroduced into the park, the top predators have helped parts of the ecosystem bounce back.

What is the principle of impulse-momentum?
What is the principle of impulse-momentum? The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it. The impulse-momentum theorem is logically equivalent to Newton’s second law of motion (the force law). What is impulse principle? The Principle of Impulse and Momentum describes how an object’s linear and […]
