HELP!!!! FAST!!!! 20 POINTS!!!! You are a traffic accident investigator. You have arrived at the scene of an accident. Two trucks of equal
mass (3,000 kg each) were involved in a rear-end accident at a stop sign. Here is what you know:
• Truck 1 started from rest at the top of a 22-meter hill and coasted toward the intersection.
.
Truck 2 was on a flat stretch of road at the bottom of the hill directly in front of Truck 1.
At the bottom of the hill, Truck 1 was going 20 m/s; Truck 2 was going 35 m/s.
.
There were no skid marks left by Truck 2. The collision occurred at the stop sign where Truck 2 had
stopped
• After the collision, both trucks moved together in the same direction at 10 m/s before slowly rolling
to a stop.
You must now push Truck 2, using 1,000 N of force, 8 meters off to the side of the road so no one
else gets hurt.
1. What was the potential energy of Truck 1 at the top of the hill? 2. What was the kinetic energy of each truck before the began braking? 3. A. How much energy did truck 1 lose from the top to the bottom of the hill? B. Where do you suppose that energy went?
Answer:
1) Kinetic energy of the truck 1 is 600,000 joules.
Kinetic energy of the truck 2 is 1,837,500 joules.
2 a)Potential energy of truck 1 is 646,800 Joules.
b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.
Step-by-step explanation:
Mass of the truck 1 and truck 2,m = 3000 kg
Velocity of the truck 1, = = 20 m./s
Velocity of the truck 2, = 35 m./s
1. Kinetic energy of the truck 1:
Kinetic energy of the truck 2:
2.a) Energy loose by the truck 1:
Initial height of the truck on the hill = 22 m
At that height potential energy will be maximum:
Potential energy of truck 1 at that height =
b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.

A cell that utilizes NHEJ to repair a double-stranded DNA break which occurred in the open reading frame of a gene is susceptible to indels resulting in a frame shift mutation and ultimately a non-functional protein. False True
Answer:
True
Explanation:
The non-homologous end-joining (NHEJ) pathway is a DNA repair pathway used to repair double-strand breaks that can occur throughout all cell cycle phases. Conversely to the homologous recombination (HR) pathway, the NHEJ pathway does not need a homologous template at the DNA double-strand breaks ends and therefore NHEJ is an error-prone repair pathway that may cause mutations within the repaired region of the DNA. The NHEJ pathway is well-known to induce indels (i.e., insertions and deletions) mutations that shift the reading frame of the protein (i.e., frameshift mutations), thereby leading to a completely different translated protein from the original one.

Which of the following substitutions can help reduce air pollution?
using a bike instead of a car
using dumps instead of landfills
using coal instead of oil
using fireplaces instead of a wind farms
Answer: A. using a bike instead of a car
Explanation: TRUST ME!!! Answer is correct on Edge!!! :)
Using a bike instead of a car can help reduce air pollution by decreasing the number of cars on the road and reducing the emissions of greenhouse gases and pollutants from car exhaust. Therefore, option (A) is correct.
What is air pollution?Air pollution is the presence of harmful substances in the air that we breathe. These substances can come from natural sources such as wildfires and volcanic eruptions, but are mostly caused by human activities such as burning fossil fuels, industrial processes, and transportation.
Common air pollutants include particulate matter, ozone, nitrogen oxides, sulfur dioxide, and carbon monoxide, among others. Exposure to air pollution can lead to a range of health effects, including respiratory problems, heart disease, and even premature death. Air pollution also has significant impacts on the environment, including harming ecosystems, reducing crop yields, and contributing to climate change.

There have been cases in history where a king divorced his queen because she produced only daughters. Using your knowledge of genetics, explain why this was an incorrect move.
Answer:
A child's gender (male or female) is determined by the chromosome that the male parent contributes.
Explanation:
Females have XX sex chromosomes. Males have XY sex chromosomes. A male infant results if the male contributes his Y chromosome while a female infant results if he contributes his X chromosome. Therefore, it is actually the King's fault that he is only producing female heirs.
The gender of a child is determined by the s ex chromosomes present in male and not by the female.
What are s ex chromosomes?Humans have 23 pairs of chromosomes. 22 of these pairs are called autosomes and are same in both male and female.The 23rd pair chromosome is different in male and female and are called s ex chromosomes because determines the s ex of a child.The female has two copies of X chromosomes whereas males has one X and one Y chromosome.During fertilization, the embryo receives one set of chromosomes from each parents.Child with XX chromosomes will be girl and child with XY chromosome will be boy.As, the mother can only give X chromosome then the gender of child is determined by the chromosomes he received from his father as it has both X an Y chromosomes.
Hence, the female should not be blamed if she gives birth to only daughters.

The invention of the microscope led to the discovery of the cell by Robert Hooke. While looking at cork, Hooke observed the box-shaped structures, which he called "cells" because they reminded him of the cells (rooms) found in monasteries. This discovery led to the development of the cell theory. Credit for developing the cell theory is usually given to two scientists. Theodor Schwann and Matthias Schleiden. The cell theory was then proposed by Theodor Schwann in 1839. There are three parts to this theory: living organisms are made up of cells, cells are the basic structural unit of all organisms, and all cells come from pre-existing cells. Which of these is supported by the tenets of the cell theory? Select ALL that apply. les )) A) Energy flow occurs within cells. B) Mitosis produces identical daughter cells. C) Living organisms can be unicellular or multicellular. D) DNA is copied and passed between cells during cell division. E) Single-celled bacteria grow and then divide in half to make new bacteria.

The human chromosome 1 is approximately 250 million nucleotides long. In order to reveal the sequence of human chromosome 1, the chromosome is broken up into hundreds of fragments. These fragments are then pieced together in the correct order to generate the long, continuous sequence of nucleotides in the chromosome, a process referred to as:
Answer:
The process is termed as sequence assembly.
Explanation:
The aligning and merging fragments from a longer sequence of DNA so that the original sequence can be redeveloped is termed sequence assembly in bioinformatics. The process of sequence assembly is essential as the DNA sequence technology fails to read the complete sequence of genomes in one go, and apart from that, it reads small fragments of DNA sequences between the sizes of 20 to 30000 base pairs.
