"<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:
Answer:
<u>Box 1</u>
Explanation:
Formula we are using :
<u>Force = mass × acceleration</u>
or
<u>mass = Force / acceleration</u> (since mass needs to be found)
=============================================================
Box 1 :
⇒ mass = 5 N / 5 m/s²
⇒ mass = 1 kg
=========================================================
Box 2 :
⇒ mass = 5 N / 0.75 m/s²
⇒ mass = 5 × 4/3 = 20/3 kg
⇒ mass = 6.67 kg
===========================================================
Box 3 :
⇒ mass = 5 N / 4.3 m/s²
⇒ mass = 50/43 kg
⇒ mass = 1.16 kg
===========================================================
On comparing Box 1, Box 2, and Box 3, we understand that <u>Box 1</u> has the smallest mass
Answer:
The power deposited in a metal is proportional to its electric resistance, so high-resistance metals heat more.
"Heat and matter are both able to enter or leave the system" is the one among the following choices given in the question that <span>best expresses the definition of an open system. The correct option among all the options that are given in the question is the second option or option "B". I hope it helps you.</span>
