What would you predict the ability of the beta particle to pass trough materials to be if they were ejected at speeds much less than that of near light speeds?
The ability would be reduced, since the mass is small but the charge is large.
How calculate unknown resistance?
-- Connect a source of known, small voltage across the ends of the unknown resistance. -- Measure the resulting current through the unknown resistance. -- Divide (small known voltage)/(measured current). The quotient is the formerly unknown resistance.
What is the difference between a force multiplier and a speed multiplier?
A force multiplier increases the effort force and the mechanical advantage is larger than one (Which means it is easier to move a large load with a small effort). While the speed multiplier does not make the effort easier but makes the load move through a larger distance than the effort. The mechanical advantage of a speed multiplier is usually lower than 1.
Which is greater - the terminal velocity of a small blood droplet or the terminal velocity of a large blood droplet?
The small blood droplet would have a greater terminal velocity. The smaller droplet has a smaller surface area, thus suffers less air resistance.
Why is the acceleration is faster in small objects than in large objects?
The difference is due to inertia. Inertia is the resistance to a change in motion (acceleration). A more massive object will have greater inertia, and therefore a greater resistance to a change in motion, resulting in a slower acceleration. A less massive object has lower inertia, and therefore less of a resistance to a change in motion, resulting in a faster acceleration.
When measuring a large current flow should you use a shunt with zero resistance?
It is not a shunt with zero resistance. It is very small, but it is not zero. The large current develops a small voltage across the small resistance. Measuring that small voltage gives you a proportional measurement of the current.
What is the definition of small business?
Whether small or large, "business is an organized effort by individuals to produce and sell for a profit, goods and services that satisfy societies needs."Whether small or large, "business is an organized effort by individuals to produce and sell for a profit, goods and services that satisfy societies needs."
Which conditions make resistance small?
The resistance of a wire is the length divided by the cross-section area and the conductivity of the material. So for small resistance you need a wire with short length, large cross-section area (diameter) and a material with high conductivity like copper.
Why shunt resistance is used ammeter?
A shunt resistance is a low resistance connected parallel to the galvanometer so that a large portion of current passes through the low resistance and a small fraction of current passes through the galvanometer this saves the galvanometer from damage
What is pocket resistance?
Rather than encountering an opposing battle line, or a single large city that is resisting, resistance is found prodcued by relatively small groups, dispersed in different locales.
What does large motor skills mean?
It has to do with a person's ability to use their large muscles to make large, gross motions - like a running back in football or a weight lifter. It is the counterpart of 'fine motor skills' which has to do with a person's ability to use their small muscles to perform small, fine movements - like a brain surgeon or dentist.
Which electric heater will yield the greater heat output a large resistance in the coil or a small resistance in the coil?
With the same voltage across two conductors, the conductor with the smaller resistance will dissipate more power, i.e. generate more heat.
Why in coil power factor is low?
A coil of wire acts as an inductor; it will have a very small resistance, and a relatively large inductance. Power factor is effectively the resistance divided by the impedance (made up of resistance and inductance), so the larger the inductance relative to the resistance, the lower the power factor will be.
What is the relationship between the circumferences of the gears on a ten speed bike and the effort force?
Big chainwheel(by the pedals) and small sprocket(at the rear wheel) = big effort. Small chainwheel and big sprocket = small effort
Why shunt resistance must be small in ammeter?
An ammeter has to measure to current flowing through the circuit. Resistance offers an obstruction to the current flow. So, if the resistance of an ammeter is large , the current measured by the ammeter will be quite less as compared to the actual amount of current flowing through the circuit which is undesirable. If ammeter has zero resistance , then it will give the exact value of current. But this is not practically possible because every material has some value of internal resistance which we can't control. For this reason , ammeter must have small resistance
Why do astronauts take small steps on the moon?
The gravity on the moon is much less than that of Earth. Thus, even a small step requires much less effort than on Earth. If astronauts were to take large steps, it would waste energy needlessly and probably take more effort.
How does the resistance of a wire vary with its area of cross section'?
Conversely, as the cross-sectional area of the conductor icreases, the resistance decreases, just as a pipe of large diameter offers less resistance to fluid flow than does a pipe of small diameter.
