Answer:
Explanation:
A number can be written in the form of :
Where
m is the real number
n is any integer
In this case, the average distance from the Sun to the Earth is given,
d = 150000000000 meters
There are 10 zeroes in this number. We need to write this number in scientific notation. It is given by :
So, the average distance from the Sun to the Earth is . Hence, this is the required solution.
Answer:
The cytoplasm holds all the organelles, except the nucleus.
Explanation:
Rate of change of momentum = impact force
(m*v-m*u)/t = F
4000*20/t = 80000 (note: v is zero as it stopped)
<span>soo, t = 1 sec</span>
Let’s do this together!
Okay so the acceleration formula is vf-vi over time .
So the initial velocity (vi) 7m/s final velocity (vf) is 16m/s so we’re going to subtract 16-7 which is 9
M/s
So the time is 5s so 9m/s divided into 5s is 1.8m/s/2
So the answer is 1.8m\s2
Answer:
KE = KE (incidental) - KE of emitted photons
or KE = h * f - Wf
So h * f = KE + Wf = 1.2 + 1.88 = 3.08 incident energy
If you double the frequency then h * f = 6.16
KE = 6.16 - 1.2 = 4.96 eV
