Is the change of position in an object? The change in position of an object is termed displacement. How does a force change the position of an object? Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. […]

Is being curious a sign of intelligence? Curiosity, in all its forms, appears closely tied to intelligence. In one 2016 study, researchers exploring potential factors that might impact openness looked at data following 5,672 people from birth to age 50. What makes you curious in life? These are a few of the factors that researchers […]

What happens to your body if you fall 100 feet? If you were skydiving and you fell 100 feet from the airplane, nothing bad would happen to you because you would just be in air and air wouldn’t hurt you unless it was passing by at some great velocity enough to damage your skin. What […]

Why does a metal doorknob feel colder than the wooden door? On a cold day, why does a metal doorknob feel colder than the wooden door? The metal doorknob absorbs heat from your skin faster than the wooden door, so it feels colder. Why does a wooden door feel warm when you touch it? Metal […]

What type of image can a concave mirror produce? Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as […]

What is the impedance of capacitor? Impedance of a capacitor The resistance of an ideal capacitor is zero. The reactance of an ideal capacitor, and therefore its impedance, is negative for all frequency and capacitance values. Why AC current passes through capacitor but DC can t? We know that there is no frequency i.e. 0Hz […]

What is a real life example of velocity? Velocity is speed with a direction. Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed. But saying he runs 9 km/h Westwards is a velocity. What are three examples of velocity? So whether its a car moving, a ball being dropped, or […]

What law is a car accelerates faster than a truck? Newton’s Second Law of Motion Which law takes less force to move a ping pong ball than a bowling ball? It is Newton’s Second Law of Motion. When thrown with the same force a soccer ball accelerates more than a bowling ball? A soccer ball […]

How is convergence different from frontal wedging? Answer: Convergence lifting- This is a kind of lifting of air above the ground due to the horizontal inflow of air because of which no place left for air to go except above hence moves up. Frontal wedging- This again is a kind of air lifting in which […]

What are mangroves used for? Mangroves are important to people because they help stabilize Florida’s coastline ecosystem and prevent erosion. Mangroves also provide natural infrastructure and protection to nearby populated areas by preventing erosion and absorbing storm surge impacts during extreme weather events such as hurricanes. What is the benefit of mangrove? The sturdy root […]
