Explanation:
scientific laws are totally fixed.
sciebtific theories are not totally accurate.
THEY WORK TOGETHER TO CREATE A TISSUE OR A WORKING ORGAN
Answer:
work =p×v =3.27×10^5×1.5×10^-3 =490.5 joule
efficiency =w/q in
:. qin= w/efficiency =490.5/0.225=2180 joule
qout =q in - work =1689.5 joule
q out is work given as heat
Answer:
a) E = 1.47 × 10^5 N/C
b) south
Explanation:
The magnitude of an electric field can be defined mathematically as;
E = F/q ........1
Where,
E = magnitude of the electric field
F = electric force
q = charge on the proton
Given;
F = 2.36 × 10^-14 N
Note that charge on a proton is known as Qp = 1.602 × 10^-19 C
q = 1.602 × 10^-19 C
Substituting into equation 1, we have;
E = 2.36 × 10^-14 N/1.602 × 10^-19 C
E = 1.47 × 10^5 N/C
b) The direction of the electric field;
From equation 1
E = F/q ........1
since both electric field and electric force are vector quantity and q is a positive charge (constant), then both the electric field and electric force would be parallel to each other. Therefore the electric field is directed to the south also.
(When a vector is multiplied by a positive constant the direction remains the same)
