Answer:
(a) Current will be 
(b) Number of ions will be 
Explanation:
We have given that resistance of the biological cell 
(a) We have given potential difference of 75 mV
So 
From ohm's law we know that current is given by
(b) We have given time t = 0.74 sec
We have to find the charge
We know that charge is given by Q = it, here i is current and t is time
So charge will be 
So number of ions will be 
The kind of wave it is Longitudinal
The kinetic energy of an object is given by:
where
K is the kinetic energy
m is the mass of the object
v is its velocity.
The comet in our problem has a mass of
and a velocity of
, so its kinetic energy is:
The correct answer is C.) a leaf
Answer:
10
Explanation:
The atomic number is only based on the number of the elements protons. The neutrons and electrons will only change the atomic mass and properties of the element. So the atomic number is 10.
