What is the meaning of a null hypothosis being rejected

Biology
1 answer:
Margarita [4]3 years ago
7 0
Null hypothesis<span> are never accepted. We either </span>reject<span> them or fail to </span>reject<span> them. The distinction between “acceptance” and “failure to </span>reject<span>” is best understood in terms of confidence intervals. Failing to </span>reject<span> a </span>hypothesis means<span> a confidence interval contains a value of “no difference”.

Hope this helps. </span>

Over the decades local and global ice ages have lowered sea levels. As a result, there is often a decline in marine diversity du
Annette [7]

Answer:

B) Changes in the temperature and salinity of water.

Explanation:

<em>Options</em>:

A) Migration of bottom feeders into the region.

<u>B) Changes in the temperature and salinity of water. </u>

C) Migration of fresh water fish to places near the mouths of rivers.

D) Formation of breeding grounds for various species in the shallow waters.

Sea level changes are among the most relevant issues that our planet is facing due to climate change. This phenomenon impacts the salinity and temperature of the ocean because of the melting of glaciers, and ice sheets. Therefore, <u>melting ice alters the level of salinity of the water which, along with temperature, also effect the density of the ocean water, altering ocean currents and productivity.</u> These impacts alter the distribution, behavior, and ecology of marine organisms.

<em>*Note: The melting of the glaciers and ice sheets - result of anthropogenic climate change - has increased sea level.</em>

A proton has a speed of 3.0 × 106 m/s in a direction perpendicular to a uniform magnetic field, and the proton moves in a circle
jeyben [28]

Answer:

The magnitude of the magnetic field is 0.156 T.

Explanation:

Given that,

Speed of a proton, v=3\times 10^6\ m/s

Radius of the circular path, r = 0.2 m

When the proton enters in the circular path, the centripetal force is balanced by the magnetic force such that :

\dfrac{mv^2}{r}=qvB\sin\theta

q is the charge on proton

Here, \theta=90^{\circ}

\dfrac{mv^2}{r}=qvB\\\\B=\dfrac{mv}{qr}\\\\B=\dfrac{1.67\times 10^{-27}\times 3\times 10^6}{1.6\times 10^{-19}\times 0.2}\\\\B=0.156\ T

So, the magnitude of the magnetic field is 0.156 T. Hence, this is the required solution.
