If you throw a ball straight up into the air, when is the kinetic energy the greatest?

Question 4 options:

Right before you catch it after it falls back down.


When the ball reaches the highest point and stops briefly.


Half the distance on the path traveling back down.


Half the distance on the path traveling up in the air.

Answers

Answer 1

Half distence on the path traveling up in the air.

Explanation:

When the ball is on thr ground there and not moving there is no potential energy or kinetic energy, when the ball is tossed into the air it will reach maximum height which is determined by how much kinetic energy it has (air resistence is important however) when the ball reaches its velocitu is 0 and all of the energy in the system is potential energy, as the ball falls to the ground that potential energy is converted to kinetic energy

Answer 2

If a ball is thrown straight up into the air, the kinetic energy is greatest when the distance is half on the path travelling up in the air. Thus, the correct option is D.

What is Kinetic energy?

Kinetic energy is the energy associated with the body which is under motion. Kinetic energy is directly proportional to the distance, mass and velocity of the object.

When the ball is thrown on the ground and is not moving then there will be no potential energy or kinetic energy as the height and velocity is zero when the object is on ground. When the ball is tossed into the air, it will reach maximum height which is determined by the kinetic energy it has and the air resistance when the ball reaches zero velocity and the greatest kinetic energy is observed when the body attains half of the total distance on the path.

Therefore, the correct option is D.

how will climate change affect the habitat distribution for the baltimore oriole?

Answers

Climate change has a great effect on the habitat distribution of Baltimore orioles bird.

Climate change will adversely affected the habitat distribution of Baltimore orioles because climate change causes heat waves, wildfires and intense downpours which is harmful for Baltimore orioles.

The climate changes will limit the populations of ranges of Baltimore oriole as well as changes the habitat. These Baltimore orioles moved to other places where the climate is favourable so we can conclude that climate change has a great effect on the habitat distribution of Baltimore orioles bird.

Describe why enzymes are important in all living organisms?

Answers

Answer:

Enzymes are important because they make the chemical reactions in cells happen quickly.

Enzymes, by speeding up biological reactions, ensure that all necessary activities in a cell can take place simultaneously and prevent one particular activity from overtaking the entire cell or organism. This is possible because enzymes allow chemicals to react more specifically with only certain substances rather than reacting indiscriminately with any number of different substances within cells.

The most famous example of this enzyme effect is when stomach acid reacts with pepsin that turns food into a liquid. The body then uses this liquid for absorption through the intestines where nutrients are then used throughout the body. It's important for people to have enough enzymes in order to digest their food fully however if

how might differences in enzyme concentrations affect rates of photosynthesis and respiration?

Answers

Answer:

enzymes are biological catalysts which speed up the rate of biochemical reactions

Increasing the concentration of enzymes would speed up the rate of photosynthesis and respiration due to the fact that the enzyme substrate complex can occur on a much larger scale i.e. more enzymes would be able to bind with more substrates producing more Oxygen in the case of photosynthesis and more ATP in respiration

Decreasing the concentration of enzymes would have the opposite effects

The differences in enzyme concentrations affect rates of photosynthesis and respiration are process accelerators.

What enzymes are involved in photosynthesis?

Enzymes such as Rubisco, sedoheptulose-1,7-bisphosphatase, aldolase and transketolase dominate the control of photosynthesis. Reductive fixation of CO2 requires ATP and NADPH and their concentrations in the stroma increase when chloroplasts are illuminated.

The chemical reactions involved in photosynthesis are controlled by enzymes . The temperature increases the number of collisions increases, therefore the rate of photosynthesis increases. However, at high temperatures, enzymes are denatured and this will decrease the rate of photosynthesis.

What is biotechnology?

Biotechnology is the application of biology to the problem-solving and product-making processes. The most well-known application of biotechnology is the use of genetic engineering to produce therapeutic proteins and other medications.

Because the production of antimicrobial metabolites (such as organic acids, ethanol, and bacteriocins) lowers the danger of contamination with pathogenic bacteria, food fermentation has historically been used as a preservation technique.

Explanation:

If a true-breeding tall pea plant is crossed with a true-breeding dwarf pea plant and all of the offspring are tall plants, the trait tall plant is it is dominant over "dwarf plant."

What is dominant traits?

Dominant traits are always explained when the related allele has dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.

The frequency of expression of dominant and recessive traits can be Dominant traits = always / Recessive = sometimes.

According to the question if there is self cross TT×tt then there is TT, Tt, Tt and tt, which means there is a 75% possibility of dominant trait and 25% recessive.

A dominant trait has an inherited trait or characteristic that appears in an offspring and covers the effects of another allele and/or prevails or exhibit its trait above another.
