Answer:
1 m
Explanation:
L = 100 m
A = 1 mm^2 = 1 x 10^-6 m^2
Y = 1 x 10^11 N/m^2
F = 1000 N
Let the cable stretch be ΔL.
By the formula of Young's modulus
ΔL = 1 m
Thus, the cable stretches by 1 m.
Answer:
The answer is "Option B and Option D"
Explanation:
Isopropyl alcohol has an air pressure of 22,39 units with such a water contact angle of 72,86 units.
The melting points of Isopropyl alcohol are higher than water because of the weaker forces between the previously studied.
The flatter meniscus is indeed the isopropyl ethanol so because forces between the particles are smaller.
The answer is : both lines should be the same lenght. Before towing 2 skiers, make sure the tow lines are of the same length if towing multiple skiers,and that they should wear a U.S. Coast Guard—approved life jacket (PFD) designed for water-skiing.
Answer:
B) 12 m
Explanation:
Gravitational potential energy is:
PE = mgh
Given PE = 5997.6 J, and m = 51 kg:
5997.6 J = (51 kg) (9.8 m/s²) h
h = 12 m
Reactants is a starting substance in a chemical reaction; (reactants appear on the left-hand side of a chemical equation).
Products is a substance produced in a chemical reaction; (products appear on the right-hand side of a chemical equation).
Limiting reactant is the reactant that has the smallest stoichiometric amount in a reactant mixture and consequently limits the amount of product in a chemical reaction.
