What kind of charging occurs when you slide your body across a plastic surface? Electrostatics: When a person slides across a plastic surface, the plastic produces a net negative charge and your body surface a net positive charge. What will happen if you switch the battery so that the positive end is on the right […]

Why do land breezes occur at night? Land breezes usually occur at night because during the day the sun will heat land surfaces, but only to a depth of a few inches. At night, water will retain more of its heat than land surfaces because water has a high heat capacity. How are sea and […]

Does transfer intent apply conversion? Transferred intent may occur through a transfer of intent from person to person, or from tort to tort. Transferred intent is applicable to assault, battery, trespass to land, trespass to chattels, and false imprisonment, but transferred intent is not applicable to IIED or conversion. What is the difference between theft […]

What is simple harmonic motion write its any four characteristics? (i) In SHM, acceleration of the particle is directly proportional to its displacement, and directed towards the mean position. (ii) It can be represented by a single harmonic function of sine or cosine. (iii) Total energy of the particle executing SHM remains conserved. (iv) It […]

What are examples of spore bearing plants? Algae, mosses, and ferns are some examples of plants that produce spores. Although they belong to different clades, they share the same type of reproduction, which is thought to be quite common in the Kingdom Plantae until some groups evolved into seed-bearing plants as another form of reproduction. […]

Are aluminum bats allowed in Major League Baseball? Aluminum bats are used in college, high school and little league ball, but they’re illegal in the major leagues where hitters must use wooden bats. The issue is the velocity with which balls come off the bat, otherwise known as bat-exit speed. Where do you bat your […]

Is 100 degrees Celsius hot? No. We can say that the temperature of boiling water is 100°C(or 100 K) more than the temperature of ice cold water. The highest temperature obtained in the large hadron collider is 5.5 trillion degrees Celsius while the temperature on the surface of sun is 5600°C. However, sun has much […]

What affects condensation? Two things must be present for condensation to occur: warm moist air, and cool surface temperatures below the dew point. The proper control of these two factors can minimize condensation. What is the main cause of condensation? Condensation occurs when warm air collides with cold surfaces, or when there’s too much humidity […]

What is the difference between successful people and normal people? Ordinary people set goals, successful people set detailed plans of actions. Successful people set their goals as well. More importantly, however, they create a detailed set of actions they need to perform in order to achieve their end goal. What is the difference between ordinary […]

What three structural groups shown do all amino acids have in common? All amino acids have the same backbone structure, with an amino group (the α-amino, or alpha-amino, group), a carboxyl group, an α-hydrogen, and a variety of functional groups (R) all attached to the α -carbon. What are the 4 major biological macromolecules? Types […]
