Why is Dr. Elizabeth Cochran’s sensor important to earthquake research? How can it help develop an earthquake warning system?

Answers

Answer:

According to Cochran, these sensors become temporary seismic stations, enabling scientists to automatically monitor and retrieve data from six months to a year after an earthquake. Therefore, scientist can detect earthquake through information collected from the last earthquake.

Explanation:

Answer:

Dr. Cochran has invented a device to use on any laptop to detect an earthquake. This device can warn people about earthquakes immediately. These detectors are inexpensive and work on any computer. Scientists can create more of these sensors and distribute them to all residents in earthquake-prone areas. The sensors would let people know about earthquakes so they could go somewhere safe without wasting time.

what are 3 characteristics that adenoviruses, tv virus, and papilloma viruses have in common

Answers

Answer:

The three characteristics that adenoviruses, T7 viruses and papillomaviruses have in common include the following:

1. The three types of viruses possess icosahedral structures.

2. The viruses possess DNA.

3. Their DNA is double stranded.  

Adenoviruses are naked (non enveloped) icosahedral nucleocapsid viruses, which has double stranded DNA genome. They are specific to vertebrate hosts and cause different types of diseases. T7 virus is a bacteriophage that infect bacterial cells. Most strain of E.coli are susceptible to this virus. Humanpapilloma viruses are small,naked icosahedral viruses which infect higher vertebrates.

A skateboarder drops in off the top of one side of the half pipe shown below. She does not push off and starts from rest. She stands straight as she skates down one side and up the other. She expected to get to the top of other side but didn’t make it. The skateboarder recalled the law of conservation of energy from science and didn’t understand why she didn’t make it to the top of the other side.

Which of the following actions would help the skater reach the top of the other side of the half pipe?


Lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.


Hold a weight in order to increase her mass and cause the skateboard to move with a greater velocity down the half pipe.


Sit on the skateboard in order to lower her center of mass and increase the potential energy of the skateboard.


Push off at the bottom of the half pipe in order to replace lost energy and add kinetic energy to the skateboard.

Answers

The actions that will help the skater reach the top of the other side of the half pipe is to lubricate the wheels in order to reduce frictional force that is causing the skateboard to lose velocity and bend down while skating off the side and bottom of the half pipe.

The law of conservation of energy from science states that energy can neither be created nor destroyed but can be transformed from one form to another.

The skateboarder couldn't make it to the top of one side of the half pipe because the kinetic energy that was generated was converted to heat energy through friction.

As the heat energy is lost to the surrounding environment, the skateboard loses velocity.

Bending down by the skateboarder will provide additional energy to make up for the lost energy.

Therefore, in order for the skateboarder to reach the top of the other side of the half pipe, she has to lubricate the wheels in order to reduce frictional force that is causing her to lose velocity and bend down while skating off the side and bottom of the half pipe.
