Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas

v1 = 0.25 m / t1, and

v2 = 0.25 m / (t2 – t1)

where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. Record these velocities, to two decimal places, in Table E.

What is the first velocity of the car with two washers at the 0.25 meter mark?

m/s

What is the second velocity of the car with two washers at the 0.50 meter mark?

m/s

Answers

Answer 1

(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.

(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.

What is velocity?

Velocity is the rate of change of displacement with time. The velocity of the  cars depends on displacement and time of motion.

First velocity of the car at the 0.25 meter mark

The first velocity is calculated as follows;

v1 = 0.25 m / t1

let t₁ = 2 s

v₁ = 0.25/2

v₁ = 0.125 m/s

Second velocity of the car at the 0.5 meter mark

v2 = 0.25 m / (t2 – t1)

let t₂ = 3 s

v₂ = 0.25(3 - 2)

v₂ = 0.25 m/s

Plants are able to produce energy from sunlight through photosynthesis. How do the products of photosynthesis in plants benefit animals, who cannot produce energy from sunlight?

Answers

Answer:

They produce sugars in order to survive and grow. Animals eat plants and take advantage of the nutrients produced by the plants. They also breathe in the oxygen produced as a by-product of photosynthesis

Explanation:

Plants use the energy in sunlight, water, and carbon dioxide to produce sugars which are used to provide chemical energy to power cellular processes. These sugars are also stored as starches.

Animals cannot produce their own food, and instead, rely on plants and other animals as a food source to power their own processes. Animals eat plants and obtain the food that plants have produced by photosynthesis. This is mostly carbohydrates (sugars and starch) but also some fats, proteins, and vitamins.

Based on this excerpt, what is most likely true about ancient Greek marriage rituals? The groom had to perform a brave feat before marrying the bride. The groom had to ask the bride’s parents for permission to marry her. The bride’s parents made all the arrangements for the couple’s marriage ceremony. The bride’s parents chose whom the bride would marry when the girl was very young.

Answers

Answer:

The correct answer is:

The groom had to ask the bride’s parents for permission to marry her.

Explanation:

Marriage in ancient Greek was less of a personal relationship than it was a social relationship. Asking a parent or guardian by the groom for permission to marry the bride is a tradition that spans several cultures and was also evident in ancient Greek marriage rituals. The permission is usually given by the father, and once that happens, the couple is officially engaged. Marriages were also arranged through the meeting of the fathers of the young couple, basing the marriage on their interests in expanding a business or forging an alliance between the families, with little concern about what the groom thought of the situation, and no regard for what the wife wished

Answer:

B. The groom had to ask the bride's parents for permission to marry her.

O E is the same distance from A and B.
plz help me understand this

Answers

Answer:

Option - E is the same distance from A and B.

Explanation:

Perpendicular bisector  can be understood by this explanation:

If line n is intersected by line n at the center of line n

, then  line m is the perpendicular bisector of line n

There are 4 right angles formed due to this perpendicular bisector around this mid-point

∵ Line CD ⊥ of segment AB

∴ Line CD intersects segment AB at the middle point of AB

∵ Line CD and segment AB intersected at point E

so, E ∈ AB  and  E ∈ CD

⇒ Point E is the mid-point of line AB

⇒ E is the same distance from A and B.

Thus, the correct option is -  E is the same distance from A and B.

Tissue level of organization is characterized by a group of cells that work together to perform a common function

A group of cells that work together to perform a common function is known as a tissue. Tissues can be classified into four main types: epithelial, connective, muscular, and nervous tissue.

Epithelial tissues are responsible for covering and lining surfaces, while connective tissues provide support and protection to the body. Muscular tissues enable movement, while nervous tissues control and coordinate body functions.

Therefore, Tissues are the building blocks of organs that are made up from cells , which in turn make up organ systems, and ultimately form an organism.

When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?

Answers

Energy cell harvesting is impotant. Cells need energy so they can move from one place to another and ATP helps that. ATP is consiered "energy currency" of the cell and it's useful for storing egery and helping molecules/cells move around.

Protein to move against concentration gradient requires energy. Protons go trhough a protein channel called ATP synthase which helps them move out of the mitrochonrial matrix.

The phosphorylation of another molecule can assist a protein to transport molecules against their concentration gradient by energizing them.

PHOSPHORYLATION:

Phosphorylation is the process by which a phosphate group is added to another molecule.

Adenosine triphosphate (ATP) loses a phosphate group to another molecule in the process of phosphorylation to energize the molecule. This is the process by which energy is released for use.

Moving molecules against a concentration gradient requires energy input in form of ATP, hence, phosphorylation can assist a protein to transport molecules against their concentration gradient by energizing them.
