Answer:
given d= 10.2x10-3m
change in diameter d' =3.4x10-6 m
elastic modulus=207x109pa
1/m=0.30
we know that stress/strain=E
but poissons ratio 1/m = lateral starin/longitudinal starin
0.3= (d'/d)/(L'/L)
L'/L = 3.4x10-6/(0.3x10.2x10-3)
= 1.11*10-3
E= (f/A)/(L'/L)
force f= E*A*(L'/L)
f =(1.11*10-3)*207*109*(3.1415*(10.2*10-3)2)/4
= 18775.2N =18.775KN
Explanation:
The force that produce an elastic reduction is 18.775KN
Answer:
4.2·10⁷
Explanation:
Exponents are added when multiplying:
(a^b)(a^c) = a^(b+c)
1.15·10⁵ × 3.65·10² ≈ 4.2·10⁷
_____
Your calculator is designed to work with scientific notation. Scientific or graphing calculators can also display their output in scientific notation. A spreadsheet can also perform this calculation for you and display the result in the required format.
Calculators and spreadsheets sometimes use "E" in place of "×10^". That is, 4.2E7 means 4.2×10^7.
Answer:
This pictogram indicates that the chemical is toxic and dangerous.
Explanation:
Answer: Application.
Explanation:
The question on wether to contine the use of cadavers in the lab for test is being centered around its application. Cadaver which is same as a corpse or dead body is used in crash site during automobil test in lab, some of this cadavers are been disrespected with their applications in the automobile industries because many didn’t consent to be used in those experiments or test.
