Determine the mass of 2.5 cups of water if the density of water is 1.00 g/cm^3 and 1 cup = 240 mL

Answers

Answer 1

Answer: 1) we find out the volume of the water.
Remember: 1 ml=1 cm³
Volume of the water=number of cups x volume of one cup.
Volume of the water=2.5(240 ml)=600 ml=600 cm³

Density=mass/volume ⇒ mass=density x volume

2) we calculate the water mass of 600 cm³ of water.
mass=density x volume
mass=(1 g/cm³)(600 cm³)=600 g.

Answer: the mass of 2.5 cupas of water is 600 g.

What is a significant advantage to the cell in having pyruvate dehydrogenase consist of a large

Answers

Answer: Pyruvate dehydrogenase consists of three enzymes: -Pyruvate dehydrogenase, Dihydrolipoyl transacetylase, and Dihydrolipoyl dehydrogenase. The short distance between these enzymes allows channeling of substrates which minimizes the side reactions.

Glycolysis or glycolysis (from glycos, sugar, lysis, breakdown) is the metabolic pathway responsible for oxidizing glucose to obtain energy for the cell. It consists of 10 consecutive enzymatic reactions that convert glucose into two molecules of pyruvate, which is able to follow other metabolic pathways and thus continue to deliver energy to the body

Which of the following currents is associated with downslope movements of dense sediment-rich water? (1 point) avalanche current density current turbidity current longshore current

Answers

The current that is associated with downslope movements of dense sediment-rich water is called turbidity current.

Answer : Option C) Turbidity Current

Explanation :

The current that is associated downslope movements of dense sediment-rich water is turbidity current.

A turbidity current is most typically termed when an underwater current of usually rapidly moving, which has high sediment-laden water which is movies down a slope.

Turbidity currents is mostly caused by earthquakes, or collapsing slopes, or any other geological disturbances.

Answers

The correct answer is letter A. We use the formula, v=vo + at to get the answer.

v=vo + at
v=0 + (9.8)(8)
v=78.4

y=1/2(vo + v)t
y=1/2(78.4)(8)
y=1/2(627.2)
y=313.6m

The answer will be A 313.6
