Answer:
He realized he needs to have the upper body and lower body held in place and needed the buckle as far down beside the person's hip so it could hold the body properly
Explanation: ''I realized both the upper and lower body must be held securely in place with one strap across the chest and one across the hips,'' Mr. Bohlin once said. ''The belt also needed an immovable anchorage point for the buckle as far down beside the occupant's hip, so it could hold the body properly during a collision.
Answer:
The mass percentage of the solution is 10.46%.
The molality of the solution is 2.5403 mol/kg.
Explanation:
A bottle of wine contains 12.9% ethanol by volume.
This means that in 100 mL of solution 12.9 L of alcohol is present.
Volume of alcohol = v = 12.9 L
Mass of the ethanol = m
Density of the ethanol ,d=
Mass of water = M
Volume of water ,V= 100 mL - 12.9 mL = 87.1 mL
Density of water = D=1.00 g/mL
Mass percent
Molality :
M = 87.1 g = 0.0871 kg (1 kg =1000 g)
Answer:
The correct answer is "8".
Explanation:
The formula to calculate the number of peptides that can be synthesized from a certain number of different amino acids is given as follows:
"n^r"
where "n" is the number of amino acids and "r" is the length of the peptide.
In this case,"n" is 2, since the peptides are synthesized with 2 different amino acids: leucine and histidine; and "r" is 3, since the length of tripeptides is 3 amino acids.
Therefore, the number of distinct tripeptides is given by the formula "2^3", which is "8".
