What three things can change velocity? An object can change velocity in a number of ways: it can slow down, it can speed up, or it can change direction. A change in speed, or a change in direction, or a change in both speed and direction means that the object has a change in velocity. […]
Can an explosion trigger an earthquake?
Can an explosion trigger an earthquake? A nuclear explosion can cause an earthquake and even an aftershock sequence. However, earthquakes induced by explosions have been much smaller than the explosion, and the aftershock sequence produces fewer and smaller aftershocks than a similar size earthquake. Not all explosions have caused earthquakes. Can a nuke cause a […]
Why is a car crash inelastic?
Why is a car crash inelastic? Collisions are considered inelastic when kinetic energy is not conserved, but this could be from either a loss or gain or kinetic energy. For example, in an explosion-type collision, the kinetic energy increases. It is common for people to try to conserve energy in a collision. What happens in […]
Why capacitors are of little use for storage of energy?
Why capacitors are of little use for storage of energy? Capacitors are not ideal for energy storage because they discharge very fast and then they are of no use until recharged. Explanation: They are designed to perform different tasks than a battery. They are not suitable to deliver slow discharge for a long time like […]
How do you convert temperature to heat?
How do you convert temperature to heat? When heat transfer is involved, use this formula: change in temperature = Q / cm to calculate the change in temperature from a specific amount of heat added. Q represents the heat added, c is the specific heat capacity of the substance you’re heating, and m is the […]
Why is Nhst bad?
Why is Nhst bad? NHST is unsuitable for large datasets Most NHST studies rely on nil null hypothesis testing (Nickerson, 2000) which means that H0 expects a true mean difference of exactly zero between conditions with some variation around this true zero mean. The p-value is smaller if the test statistic is larger. Why is […]
Are opposite angles equal in a parallelogram?
Are opposite angles equal in a parallelogram? A parallelogram is a quadrilateral whose opposite sides are parallel. The opposite angles of a parallelogram are equal. The opposite sides of a parallelogram are equal. Are all angles in a parallelogram 90 degrees? A Parallelogram can be defined as a quadrilateral whose two s sides are parallel […]

How can I strengthen my weak muscles naturally?
How can I strengthen my weak muscles naturally? While a program of aerobic activity – brisk walking, jogging, swimming – may boost your energy level, the only way to strengthen muscles is through strength training or “resistance” exercise (in other words, weight lifting). And be prepared to work pretty hard at it. What exercise gets […]
Which organelle is responsible for storage?
Which organelle is responsible for storage? Cell Organelles A B vacuole storage tank for the cell chromosome made of DNA – directions all activities in the cell golgi body sorts and packages things to be delivered – mailroom lysosome pushes trash vacuoles out the cell, digests old cell parts, breaks food down into smaller pieces […]
