Answer:
Dont have an answer but maybe this will help
Step-by-step explanation:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
This triangle is a scalene triangle because all three of the side lengths aren't equal.All of the three angles have different measures.This triangle would have been classified as acute because the angles are less than 90 degrees.If all angles were 90 degrees then it would be right and if they were more than 90 it would have been an obtuse triangle.Hope this helped!!!!!!!!
Answer:
Anwar
Step-by-step explanation:
Find the price of one book
Anwar- Rs. 25÷ 5 = Rs 5 for one book
Deepak- Rs 240 ÷ 8 = Rs 30 for one book
Therefore Anwar bought the books at a lower price
Answer:
a) k
= 3.6 N/m ; b) 9.43 * 10¹²; c) 1.18 * 10¹¹; d) 75.08 N/m
Step-by-step explanation:
Length of iron bar = L = 2.7m;
side length of cross section = a = 0.07cm = 0.0007m;
x = 2.7 cm = 0.027m;
m = 100kg;
ρ = 7.87gm/cm³;
da = 2.28 * 10⁻¹⁰m;
a)
Fnet = F - mg
where Fnet = 0
So,
F = mg where F=kx
k = mg/x = 100*9.8/0.027
k = 3.6 N/m
b)
Nchain = Aw/Aa =a²/(da)²
= (o.ooo7)²/(2.28 * 10⁻¹⁰)²
= 9.43 * 10¹²
c)
Nbond = L/da = 2.7/2.28 * 10⁻¹⁰
= 1.18 * 10¹¹
d)
Spring stiffness of wire = ksi = (Nbondk)/Nchain
= [(1.18* 10¹¹)(6*10⁴)]/(9.43 * 10¹²)
= 75.08 N/m
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
