1) A vehicle is traveling at 150 km/h after 3 hours it is traveling 240 km/h.
Was the vehicle accelerating or decelerating and at what rate?
(And this is for science not biology)

Answers

Answer 1

Answer:

Accelerating (30km/hr²).

Explanation:

In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.

This simply means that, acceleration is given by the subtraction of initial velocity from the final velocity all over time.

Hence, if we subtract the initial velocity from the final velocity and divide that by the time, we can calculate an object’s acceleration.

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

[tex]a = \frac{v - u}{t}[/tex]

Where,

a is acceleration measured in [tex]ms^{-2}[/tex]v and u is final and initial velocity respectively, measured in [tex]ms^{-1}[/tex]t is time measured in seconds.

Given the following data;

Initial velocity, u = 150km/h

Final velocity, v = 240km/h

Time, t = 3 hours

Substituting into the equation, we have;

[tex]a = \frac{240 - 150}{3}[/tex]

[tex]a = \frac{90}{3}[/tex]

Acceleration, a = 30km/hr²

Therefore, the vehicle is accelerating at the rate of 30km/hr² because its final velocity is greater than its initial velocity.

For deceleration, the final velocity of an object such as a vehicle would be lesser than the initial velocity.

Which statement describes the offspring of the F1 generation when crossing a pea plant that is true breeding for green seeds with a pea plant that is true breeding for yellow seeds?
The green trait is the dominant trait.
The offspring will inherit one allele from each parent.
The offspring will have both green and yellow seeds.
Each offspring will have a unique set of alleles.

Answers

Answer:

The offspring will inherit one allele from each parent

Explanation:

Just did EDGE

The statement 'the offspring will inherit one allele from each parent' describes the offspring of the F1 generation when crossing a pure green seeds pea plant with a pure yellow seed pea plant.

What is an allele?

An allele is a given gene form, diploid organisms inherit two alleles for gene locus, one from each parent.

A diploid individual can be for a given gene locus:

Homo-zygousHeterozygous

An individual is homo-zygous when it inherits the same allele or gene variant for a particular gene locus.

Conversely, an individual is heterozygous when it inherits different alleles for a given gene locus.

In conclusion, the statement 'the offspring will inherit one allele from each parent' describes the offspring of the F1 generation when crossing a pure green seeds pea plant with a pure yellow seed pea plant.

Explanation:

The crossing of two plants of pure line, one dominant and one recessive, for a trait —the color of the flowers— will produce a hybrid offspring which will express the dominant trait in its phenotype.

Parental generation:

Plant with purple flowers PP Plant with white flowers pp

Cross: PP X pp

Offspring: 100% Plants whose phenotype is purple flowers and Pp genotype.

According to this, the descendants will be 100% plants with purple flowers, hybrids, since all the offspring received at least one dominant allele.
