When you talk about rate, you will expect that it will be in terms of a time unit. It measures how fast it is going. So, you would expect that the denominator is in time units. For the movement, you can measure this with either distance or velocity.
So, for the first variety, you would need distance and time to measure the rate of how far you go at a certain time. It is also called as velocity. For the second variety, you would need velocity and time to measure the rate of how fast you are going at a certain interval. It is also called as acceleration.
Answer:
a) σa−σb−σc−σd=0
Explanation:
The parallel plate capacitor is the one in which two metal plates are connected in parallel with some distancing among them. The electric field from both plates is denoted by E = σ / 2ϵ0. The σ is the charge density. The Electric field in plate I will vanish when the surface charge of σa is positive and rest of the charges are negative. The correct option is a.
The statement ‘An advantage of
electron microscopes compared to light microscopes is that electron microscopes
are inexpensive and commonly used in most biology laboratories allow you to view living cells, while light microscopes
do not have higher resolution that allows you to view smaller specimens allow
you to view the true colors of the specimens being viewed’ is true. In fact,
electron microscope is more efficient than a light microscope due to its
mechanism using only light without magnifying the specimen a thousand times.
Answer:
Their differences are most likely due to non shared environmental influences
