Answer:

B

Explanation:

Both low and high mass stars begin as nebulae, then become protostars.  Both use nuclear fusion to form hydrogen in the main sequence.

The differences are that low mass stars have longer life cycles and become white dwarfs.  High mass stars have shorter life cycles and undergo supernova explosions.

Which of the following is NOT an example of a network configuration?
Artemon [7]
Of the options presented in the problem, SAN would be the the exemption of the 4 which is not a network configuration.

LAN or Local Area Network, MAN or Metropolitan Area Network, and WAN or Wide Area Network are examples of a network configuration and are arranged in this solution by their capacity area if they were to be ranked. SAN or Storage Area Network only deals with storage devices and aren't that much connected with the other three presented in the problem.

A ball connected to a 1.1 m string and is swing in circular fashion. It’s tangential velocity is 15 m/s. What is its centripetal
musickatia [10]

Answer:

ac = 204 [m/s²]

Explanation:

To solve this problem we must use the following equation that relates the tangential velocity to the radius of rotation.

ac = v²/r

where:

v = tangential velocity = 15 [m/s]

r = radius = 1.1 [m]

Now replacing we have:

ac = (15)²/1.1

ac = 204 [m/s²]

Name and describe three measures of central tendency used to summarize data.
OLEGan [10]

Answer:

Explanation:

You can think of it as the tendency of data to cluster around a middle value. In statistics, the three most common measures of central tendency are the mean, median, and mode. Each of these measures calculates the location of the central point using a different method.

There are three main measures of central tendency: the mode(the number that occurs most often) the median ( the middle value in the list of numbers) and the mean (the average number in the list of numbers).

A cat walks along a plank with mass M= 7.00 kg. The plank is supported by two sawhorses. The center of mass of the plank is a di
solong [7]

Answer:

Before the plank will tip cat will walk 1.652 m

Explanation:

Mass of the cat along with plank m_1=7kg

Center of mass of the plank d_1=0.850m

Mass of cat m_2=3.6kg

We have to find how far right of sawhorse B.

Plank will tip when weight of the cat about B is greater than the torque by the weight of the plank.

Balancing the the torque

m_1gd_1=m_1gd_2

7\times 9.8\times 0.850=3.6\times 9.8\times d_2

d_2=1.652m
