How many drops did Millikan use? Millikan’s paper of 1913 reported on 58 drops. He stated “that this is not a selected group of drops, but represents all the drops experimented upon during 60 consecutive days.” Who did the oil drop experiment? Robert Millikan’s What is the negative effect of space charge? The electrons emitted […]
What is the relationship between a neutron star and a pulsar?
What is the relationship between a neutron star and a pulsar? Most neutron stars are observed as pulsars. Pulsars are rotating neutron stars observed to have pulses of radiation at very regular intervals that typically range from milliseconds to seconds. Pulsars have very strong magnetic fields which funnel jets of particles out along the two […]
Why do electrons move from negative to positive?
Why do electrons move from negative to positive? A: Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive. Does the anode […]
How do you calculate incrementally average?
How do you calculate incrementally average? The traditional average computation first calculates the sum of the elements and then this sum is divided by the number of elements. However, the average can be calculated incrementally too, i.e. you take the 1st element and you calculate its average, then take the 2nd element and update the […]
Is the rate at which velocity changes is called acceleration?
Is the rate at which velocity changes is called acceleration? Explanation: Acceleration is defined as the rate of change of velocity. Velocity is a vector, which means it contains a magnitude (a numerical value) and a direction. So the velocity can be changed either by changing the speed or by changing the direction of motion […]
Which instrument based on the property of magnet is used to find direction?
Which instrument based on the property of magnet is used to find direction? Magnetic compass What property is used to make a compass? The directive property of magnet is used to make compass because earth has its own magnetic field and north and south poles. So, when a magnet is held free, it interacts with […]
Is oil a homogeneous product?
Is oil a homogeneous product? Still, oil is still relatively homogeneous compared to many other goods – relative to most manufactured goods, for example. It is sufficiently homogeneous to be traded on organized exchanges. In which market the goods are homogeneous? perfect competition What is a homogeneous linear equation? A system of linear equations is […]
What are the 5 main functions of the skeletal system quizlet?
What are the 5 main functions of the skeletal system quizlet? The five important functions of the skeletal system are support, protection, movement, mineral storage, and blood cell formation. Without our skeleton, our bodies would have no definite shape. The skeleton protects the internal organs. For example, the skull protects the brain. What are the […]
What causes a house to slope?
What causes a house to slope? Sloped floors are common in older homes, and even in homes as new as 15 to 30 years. Sloping floors are most often caused by normal and acceptable deflection (bend) in the wood joists which comprise the floor structure. Pronounced floor slopes can, however, be an indication of a […]
What are the 2 types of metamorphism?
What are the 2 types of metamorphism? There are two main types of metamorphism: Contact metamorphism—occurs when magma contacts a rock, changing it by extreme heat (Figure 4.14). Regional metamorphism—occurs when great masses of rock change over a wide area due to pressure exerted on rocks at plate boundaries. What are the two main types […]
