Answer:
I can't understand you're que... plzz write in a correct way..
This question can be easily solved with newton's second law of motion.
F=ma
a=F/m
=8/0.8
=10m/s^2
Answer:
<h2>
20 m/s</h2>
Explanation:
Bc Accelerations formula is V/T (velocity over time).
with this you can plug in the velocity witch is just speed with direction over time witch looks like this 140 m/s / 7 s.
and when you calculate acceleration= 20 m/s
Plz give brainliest:-)
Answer:
Length will be 0.491 nm
Explanation:
We have given wavelength of the photon 
Plank's constant 
We know that energy of the photon is given by

We know that energy of photon is also given by



Very funny. Can I do all your homework for you?
