Answer:
8400 N
Explanation:
We are given that
Mass,m=1.2 kg
Initial speed,u=-8 m/s
Final speed,v=6 m/s
Time,
We have to find the magnitude of the average force on the ball during this collision.
Change in momentum,=
Average force,
Using the formula
Hence, the magnitude of the average force on the ball during this collision=8400 N
Yes so x multiply by the hour but u add 59 for each hour to get the exath speed per minute
Answer:
conserving water is important because it keeps water pure and clean while protecting the inviorment
First shell hold up to 2 electrons.
Missing detail in the text:
"<span>A small glass bead has been charged to + 25 nC "
Solution
The force exerted on a charge q by an electric field E is given by
</span>
<span>Considering the charge on the bead as a single point charge, the electric field generated by it is
</span>
with
,
is the charge on the bead. We want to calculate the field at
:
The proton has a charge of
, therefore the force exerted on it is
And finally, we can use Newton's second law to calculate the acceleration of the proton. Given the proton mass,
, we have
The charge on the bead is positive, and the proton charge is positive as well, therefore the proton is pushed away from the bead, so:
