Answer:
1500 ms-1
Explanation:
La velocidad de una onda se obtiene de;
Velocidad de onda = frecuencia * longitud de onda
Cuándo;
Frecuencia = 600 Hz
Longitud de onda = 2,5 m
Luego se deduce que la velocidad del sonido en el agua = 600 Hz * 2,5 m = 1500 ms-1

Explanation:
6:
Answer: Newton's first law of motion,
Explanation: Inertia is the tendency of an object to resist a change it its motion. Describe how inertia affects motion. If an object is already at rest, inertia will keep it at rest. If the object is already moving, inertia will keep it moving.
7:
Answer: The second law
Explanation: The second law shows that if you exert the same force on two objects of different mass, you will get different accelerations (changes in motion). The effect (acceleration) on the smaller mass will be greater (more noticeable).
8.
Answer: Newton's Second Law
Explanation: The second law of motion explains the relationship between force, mass, and acceleration. The law states that the acceleration of an object depends on the mass of the object and the amount of force applied. Newton's second law of motion is also called the law of force and acceleration.
What height in meters must the student climb in order to reach the top of the hill?
Answer:
253 m
Explanation:
The height in meters must the student climb in order to reach the top of the hill is 253 meters. The correct option is B.
What is the height?Height is a measurement of vertical distance, or vertical extent (how “tall” something or someone is) (how “high” a point is).
Climbing is the activity of ascending a steep topographical object with one's hands, feet, or any other part of the body, which can range from the world's tallest mountains (e.g., the eight-thousanders) to little stones.
The image of a mountain is given which is climbed by a person. There are different heights of the mountain is given. The height that is a must-climb by the student to reach at the top is 253 meters.
Therefore, the correct option is B. 253 m is the height of the mountain to reach the top.

Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.
Answer:
G
Explanation:
Because this is the latest layer formed. On the other hand, you can see that A has formed its layer thousands and thousands of years ago.

The increasing trend of sexual assault and violence strongly influences the growth of the number of nurses involved in both forensic and nursing, called forensic nurses.
Answer:
True
Explanation:
Health and justice are two main powerful systems that influence the growth of the number of forensic nurses.
What is a forensic nurse?
Forensic nurses are the registered and the advanced practice nurses which have specific training and education.They provide care to the patients that suffered from prolonged acute health consequences from brutality and abuse.
They are not separate from other medical caretakers, but they are integrated into the overall care needs of individual patients.
Healthcare professionals like forensic nurses is challenged the outcomes of the physical assaults and the violence. Victims of the brutality give the primary outcomes of violence like injury.
Forensic nurses collect the evidence and give testimony that can be used in court, so that the victim get justice and punishment is given to that one who commits the brutality.

Three genes (A, B, and C) are located on different chromosomes. In a cross between
AaBCC and AabbCc (P generation) what would be the probability of seeing an
offspring with the genotype AAbbCc in the Fı generation (assuming no linkage)?
Answer:
b, a, c
Explanation:
Since recombination frequency is directly proportional to the distance between genes, the values are used to locate genes on a chromosome. Here three genes a, b and c can assume any of three linear sequences: a-b-c or a-c-b or b-a-c, which depends on the gene present in the middle. Here, recombination frequency for a and b (X) = 20%, that for a and c (Y) = 8% and for b and c (Z) =28%. As we can see that Z = X + Y or 28 = 20+8 which means that genes b and c are present at extremes and a is in the middle. Thus, the sequence of genes is b-a-c.

Which action would NOT be controlled by the somatic nervous system?
A Nodding your head
B. Sneezing
C. Petting a dog
D. Jumping over a puddle
Answer:
B. Sneezing
Explanation:
There are two types of nervous systems namely: somatic nervous system and autonomic nervous system. The somatic nervous system is that nervous system that controls the voluntary movement of muscles while the autonomic nervous system controls involuntary actions.
According to this question, nodding ones head, petting a dog and jumping over a puddle are all examples of voluntary movements, hence, are controlled by the somatic nervous system whereas, sneezing is an involuntary action controlled by the autonomic nervous system.
Sneezing because i was sneezing a lot and yea

Which class of point mutation produces a product with the same amino acid sequence as the wild-type polypeptide?
Answer:
The correct answer is - silent.
Explanation:
Silent mutation is a point mutation that takes place by a single change in a single base nucleotide of nucleic acid and it may or may not change the aminoacid sequence as the wild type protein.
This does not result in any phenotypic or functional change in the protein of the organism. It is a class of point mutation. This change can be substitution in base.
Please choose the answer that best completes the blanks of this sentence in the correct order. The ______ plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the ______ plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.
Answer:
streak, pour
Explanation:
The streak method is the most popular technique used to isolate specific bacteria from a sample containing different microorganisms. In this technique, a sterile loop is employed to obtain an uncontaminated microbial culture. Colony picking refers to the process where colonies of pure bacteria are selected in order to duplicate them by transferring them into new agar plates. Moreover, the pour plate method is the most popular technique employed to count the number of colony-forming bacteria (i.e., bacteria/ml) in a specimen. The pour plate method consists of dropping the sample on a sterile plate and subsequently molten-cooled agar is then poured into the plate and mixed well with the inoculum.
Answer:
streak, pour
Explanation:
The streak plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the pour plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.
