I=22 ÷20
Explanation:
then put the on the calculator you'll get you answer
First recall the equation that relates frequency to wavelength:
v = fw
Note that the v is the speed of light, a constant. Now plug in the information we know!
(3×10^8) = (6.67 × 10^14) w
Hit the numbers on the calculator and you'll get the wavelength, w. If you comment your answer I'll check it for you. :)
Electrons are negatively charged particles whereas protons are positively charged particles.
When a negative is shown on the bar, this means that the difference between the electrons and protons is a negative value, which also means that the number of electrons (negative particles) is more than the number of protons (positive particles).
Based on the above, the correct choice would be:
<span>D. There are more electrons than protons
</span>
<span>a cell eliminates endocytosis.

Answer:
correct answer is option A (Yes, becuase acceleration depends on the rate of change of velocity and not the value of velocity itself.)
Explanation:
we know that from first equation of motion,
v=u+at
0r
............(1)
here,
v-final velocity
u-initial velocity
a-acceleration
t-time
if a body is not moving it means if its initial velocity is zero (u=0) and if after time t it moves with velocity v then its acceleration will be given as
...........(2)
From above equation it is clear that if an object is not moving, it can be accelerating because acceleration depends on rate of change of velocity and not the value of velocity itself.
