1. The property of a conductor by virtue of which it posses the flow of electric current through it is called resistance.
2. The resistance of a conductor depends on the cross sectional area of the conductor and it's resistivity.
3.This id due to the fact that the resistance of a wire is inversely proportional to the square of its diameter.
4.Due to at high temperatures , the alloy donot oxidize. Alloy doesn't melt readily and get deformed.
Answer:
The volume of the balloon would be (580.12m) cm^3
Explanation:
From the ideal gas equation,
PV = nRT
P is pressure in the balloon = 742 mmHg = 742/760 = 0.976 atm
V is the volume of the balloon
n is the number of moles of carbon dioxide in the balloon. Let the mass of carbon dioxide be m.
n = mass/MW = m/44 = (0.023m) mol
R is gas constant = 82.057 cm^3.atm/mol.K
T is temperature of the balloon = 27 °C = 27 + 273 = 300 K
V = 0.023m × 82.057 × 300/0.976 = (580.12m) cm^3
No because the whether changes constant, weather can be close but is not the 100% the correct answer,..
Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms.
Answer:
average acceleration = −14.5 m/s²
so correct option is B) -14 m/s²
Explanation:
given data
v(t) = (2.3 m/s) + (4.1 m/s2)t - (6.2 m/s3)t²
t1 = 1.0 s
t2 = 2.0 s
to find out
What is the average acceleration
solution
we know that average rate of change on the interval is
average acceleration = ............1
so here put value of t for final f and initial i
we get Vf = 2.3 + (4.1)(2) - (6.2)(2)²
and Vi = 2.3 + (4.1)(1) - (6.2)(1)²
and t2 - t1 = 2 - 1 = 1 s
put value in equation 1
average acceleration = [2.3 + (4.1)(2) - (6.2)(2)² ] - [ 2.3 + (4.1)(1) - (6.2)(1)² ]
average acceleration = −14.5 m/s²
so correct option is B) -14 m/s²
