Drag Force = bv^2 = ma; a = g = 9.81 m/s^2
b = mg/v^2 = (0.0023×9.81)/(9.4^2)
b = 0.000255
The charge on the conductor is +24 μC, since the charge is positive, same amount of charge but it will be negative.
That is - 24 μC.
To know the number of electrons, we know that the charge of an electron =
-1.6 * 10^-19 C.
= - 24 μC / (-1.6 * 10^-19 C)
= (-24 * 10^-6) / (-1.6 * 10^-19 C) Use your calculator
= 15 * 10^13
= 1.5 * 10 ^14 Electrons.
You COULD find acceleration by taking a lot of distance measurements,
but that's definitely the hard way to do it.
Acceleration is (change in speed) divided by (time for the change).
So the basic way to calculate acceleration is to measure the change
in speed, not distance.
As elements in period are arranged according to increasing atomic weight with isotope as protium deuterium and trotium of h2 so chemical property are same but physical property different in period ic table
The mass of the given object is 475 kg.
<h3>What is kinetic energy?</h3>
This is the energy possessed by an object due to its motion. The kinetic energy of an object in motion is given as;
K.E = ¹/₂mv²
where;
- m is the mass
- v is the velocity of the obeject
The mass of the object is calculated as follows;
Thus, the mass of the given object is 475 kg.
