Observers in a distant solar system are watching our Sun and using the radial velocity method to try to determine whether the Su

n has planets. Because of the gravitational pull of Jupiter, the observers see the Sun's spectrum slowly redshift and then blueshift by a tiny amount. How long must they observe to see a full cycle?

Answer: almost 12 years

Explanation:

Using the radial velocity method, planet hunters can track a sun's spectrum, to determine whether the sun has planets. The spectrum appears first slightly blue-shifted, and then slightly red-shifted. If the shifts are regular, repeating themselves at fixed intervals of days, months, or even years, it  is almost certainly caused by a body orbiting the sun, tugging it back and forth over the course of its orbit. Because of the gravitational pull of Jupiter (about 3,000 times the mass of Earth), In which its average distance from the sun is 480 millions miles and takes nearly 12 years to make one revolution.

Aaden has decided to break up with his significant other. He has gone over what he is going to say, but can not decide where to
kow [346]

Answer:

The correct answer is: b. Channel

Explanation:

The Communication Process Model (CPM) is a model that describes the steps through which effective exchange of information takes place from the  sender of a message to the receiver(s) of the message. (Refer to attached image)

The CPM includes the following steps:

1. Noise- reducing physical/ physiological distractions that can impede clear communication.  

2. Communicator- the person who initiates the communication

3. Message- the information exchanged between the sender and receiver of the message

4. Feedback- How the information from the sender is received by the recipient of the communication

5. Channel- The medium by which the information is delivered from the sender to the receiver.

In this instance, when Aaden decided to have a discussion with his significant other in his home using face-to-face communication, he is deciding on the channel or medium through which the communication will this place. By choosing face-to-face communication at his home, Aaden has determined what he believes is the most appropriate context for the conversation with his significant other, given the sensitive nature of the topic. In this way, Aaden has selected a channel of communication.

What factors affect the amount of potential and kinetic energy a roller coaster has
Svetlanka [38]

Answer:

As the roller coaster goes higher, more potential energy is increased in the roller coaster. Caused by gravity and the roller coaster's position, the potential energy is stored in the roller coaster. For example, this ball is at the top of a hill, where potential energy is at it's highest. Potential energy can be calculated by Potential Energy=Mass X Acceleration X Height.

What temperature is required to transfer waste heat to the environment for a heat engine to be 100 percent efficient?
OLEGan [10]
This can be seen as a trick question because heat engines can typically never be 100 percent efficient. This is due to the presence of inefficiencies such as friction and heat loss to the environment. Even the best heat engines can only go up to around 50% efficiency.
