Is there any force acting on the puck now?

Is there any force acting on the puck now? What is the net force acting on the puck? The puck is moving at a constant velocity, and therefore it is not accelerating. Thus, there must be no net force acting on the puck. A hockey puck slides on ice at constant velocity. Does it take […]

Why is the speed of light faster in a vacuum?

Why is the speed of light faster in a vacuum? “Nothing can travel faster than the speed of light in a vacuum.” “Light in a vacuum always travels at the same speed.” Those additional three words in a vacuum are very important. Light traveling through anything other than a perfect vacuum will scatter off off […]

When a psychologist claims that developmental processes occur rapidly and are marked by distinct periods the psychologist most likely supports? When a psychologist claims that developmental processes occur rapidly and are marked by distinct periods, the psychologist most likely supports STAGE theories of development. Which of the following statement does not represent assumptions that stage […]

Should I use concrete for fence posts?

Should I use concrete for fence posts? Concrete is the most secure material for setting fence posts, especially if you have sandy soil. Using premixed concrete rather than dry concrete will ensure ultimate security. While concrete is sturdy, it lacks the drainage of gravel and can trap moisture, ultimately leading to rot. Will fence posts […]

What is process design and its importance?

What is process design and its importance? It’s a systematic series of steps that helps you to define, plan and produce a product you’re building — in our case, an app. It allows you to be efficient, transparent and focused on creating the best product possible. What are the typical activities of process design? Process […]

What is the probability of a recessive phenotype?

What is the probability of a recessive phenotype? In this case, there is a 1/4 chance for all recessive traits. What happens if both parents are homozygous recessive? Autosomal Recessive Genes Recessive traits are expressed only if the offspring inherits a recessive allele from each parent. If both parents are homozygous recessive — for example, […]

Why is VBE 0.7 V?

Why is VBE 0.7 V? The base emitter junction is a PN junction or you can consider that as a diode. And the voltage drop across a silicon diode when forward biased is ~0.7V. That is why most of the books write VBE=0.7V, for an NPN silicon transistor with forward biased emitter junction at room […]

How do you know if electrons are delocalized?

How do you know if electrons are delocalized? The easiest way to spot delocalized electrons is to compare electron locations in two resonance forms. If a pair appears in one place in one form, and in a different place in another form, the pair is delocalized. Which electrons are Delocalised in a metal? The outer […]

What force is required to stop a car?

What force is required to stop a car? The force needed to stop the car in 50 metres is 5,000 N. What is the force required to stop a moving object? Explanation: an external force is required to stop a moving object because the external force creates a sort of friction or a blockage for […]
