The cart with the greatest change in speed is the cart with a mass of 75 Kg

Acceleration is defined as the change in velocity of an object with time. Also, acceleration is related to the force and mass according to the following equation:

Acceleration (a) = Force (F) / mass (m)

To answer the question, we shall determine the acceleration of each cart.

a = F / m

a = 200 / 75

a = F / m

a = 200 / 125

a = F / m

a = 200 / 350

a = F / m

a = 200 / 450

From the above illustrations, we can see that the cart with a mass of 75 K has the greatest change in speed (i.e 2.67 m/s²)

D

Explanation:

F. 200-75=125

G. 20-125=75

H. 350-200=150

J. 450-200=250

250 is the biggest number so it has the biggest change

If Kelli and Jarvis maintain a forward force of 524 N for 1.44 seconds on a 158-kg piano, the acceleration will be 0.671 m/s² and the final velocity will be 0.966 m/s.

Kelli and Jarvis exert a force of 524 N on a 158- kg (m) piano.

The friction force, which opposes this force, is 418 N.

The net force (F) is the difference between both forces.

F = 524 N - 418 N = 106 N

We can calculate the acceleration (a) of the piano using Newton's second law of motion.

Newton's second law of motion states that the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force and inversely proportional to the mass of the object.

a = F/m = 106 N/158kg = 0.671 m/s²

The piano start from rest (u = 0 m/s) and moves with an acceleration of 0.671 m/s² for 1.44 s.

We can calculate its final velocity (v) using the following kinematic equation.

v = u + a × t

v = 0 m/s + 0.671 m/s² × 1.44 s = 0.966 m/s

If Kelli and Jarvis maintain a forward force of 524 N for 1.44 seconds on a 158-kg piano, the acceleration will be 0.671 m/s² and the final velocity will be 0.966 m/s.

Answer:

Proteins

Explanation:

Their Function Formation Encoded in mRNA into polypeptide chains of amino acids that produces protein

The ribosome of plant cells are sites for the synthesis of proteins. The correct option is (d).

Ribosomes are organelles that take part in the synthesis of proteins. The prokaryotic cell's ribosomes are smaller than the eukaryotic cell's ribosomes.

Currently, ribosomal RNA is a component of the cell's ribosome or protein-building machinery. The process of making proteins, or translation, is carried out by ribosomes.

The ribosome, which translates the genetic code generated in mRNA into an amino acid sequence, is universally responsible for protein synthesis. The two ribosomal subunits, small and big, come together to form the full ribosome, which is used to produce proteins.

Therefore, the correct option is (d) proteins.

The mass percentage of sugar in the sweet tea is 10%

From the question,

We are to determine the mass percentage of sugar in the sweet tea

[tex]Mass\ percentage\ of\ sugar\ in\ the\ sweet\ tea = \frac{Mass\ of\ sugar\ in\ the\ solution}{Mass\ of\ the\ solution} \times 100\%[/tex]

Mass of sugar in the solution = 20 g

Mass of the solution = 20g + 180g = 200g

[tex]Mass\ percentage\ of\ sugar\ in\ the\ sweet\ tea = \frac{20}{200} \times 100\%[/tex]

[tex]Mass\ percentage\ of\ sugar\ in\ the\ sweet\ tea = \frac{20}{2} \%[/tex]

∴ Mass percentage of sugar in the sweet tea = 10%

Hence, the mass percentage of sugar in the sweet tea is 10%

Explanation:

i think this is right :)

Explanation:

1. b is correct because 10^-2 is 1/100. multiplying that by 1.862 is 0.01862

2. 6 feet 10 inches = 82 inches. multiplying 82 by 2.54 we get 208.28. there are only two sig figs so it's 210 cm, not 0.21 cm.

3. 25.2 x 39370 = 992000, which is 9.92 x 10^5.

Considering the reaction stoichiometry and Avogadro's Number, the mass of barium chloride produced is 21.6 grams.

The balanced reaction is

2 HCl + Ba → BaCl₂ + H₂

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 1.25×10²³ molecules are contained in how many moles of HCl?

amount of moles of HCl= (1.25×10²³ molecules × 1 mole)÷ 6.023×10²³ atoms

amount of moles of HCl= 0.2075 moles

Then, 0.2075 moles of HCl react.

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

Then you can apply the following rule of three: if by stoichiometry 2 moles of HCl produce 1 mole of BaCl₂, 0.2075 moles of HCl will produce how many moles of BaCl₂?

[tex]amount of moles of BaCl_{2} =\frac{0.2075 moles of HCl x 1 mole of BaCl_{2} }{ 2moles of HCl}[/tex]

amount of moles of BaCl₂= 0.10375 moles

Being the molar mass of BaCl₂ 208.24 g/mole, then the mass of barium chloride produced is calculated as:

[tex]0.10375 molesx\frac{208.24 grams}{1 mole} =21.6 grams[/tex]

Finally, the mass of barium chloride produced is 21.6 grams.
