Hey So your equation would be ma=load/effort so we need one more part to this
Answer:
(a) 4190 rad/sec
(b) 4064 rad/sec
(c) Percentage change is 3 %
Explanation:
We have given inductance
Capacitance
We know that resonance frequency is given by
Now resistance is given as R = 1020 ohm '
(b) We know that damped frequency is given by
(c) Percentage change in frequency %
The answer to this question about solid particles would be B. Yes, they vibrate about a fixed point.
It is important to remember that the basic difference of the 3 states of matter is how their molecules are arranged. Gas molecules are situated far from each other which gives the molecules space to freely move around giving the gas its characteristics. Liquid molecules, on the other hand, are situated near to each other, where there is still space that let's them move but not as free as gas molecules. Solid molecules are very close to each other that the phrase tightly packed is but an understatement. This is also a reason that when solid particles vibrate, usually when heated, it is only about a fixed point.
Answer:
16.5 m
Explanation:
Given,
Magnetic field = 0.02 T
radius of electron = 9 mm
speed of electron = speed of proton
radius of proton = ?
We know,
.........(1)
using newton second law
equating Force due to electron and proton
m_ e = 9.1 x 10⁻³¹ Kg and m_p = 1.67 x 10⁻²⁷ Kg
Hence, the radius of proton is equal to 16.5 m.
Answer:
a) There are electrons in a liter of water.
b) The net charge is -53601707,1 C
Explanation:
a) To find out how many electrons are in a liter of water (equivalent to 1000 grams of water), we have to find out how many molecules of water there are and then multiply it by 10 (e- per molecule).
We can find out how many molecules are by finding the number of moles and then multiplying it by Avogadro's number (number of elements per mol):
b) As all electrons have the same charge, in order to find the net charge of those electrons we have to multiply the charge of a single electron by the number of electrons:
An important clarification is that while the net charge may seem huge, water as a whole is a neutral medium, because there are as many protons as there are electrons, and as they have the same charge, the net charge of water is 0.
