Coastal regions are often affected by nearby ocean currents. The map shows how different ocean currents affect the United States

Effectus [21]

Effect of Ocean currents on the Coastal regions are described below.

Explanation:

1.Ocean currents effects the temperature of the region they travel through. Warm currents increase the temperature of the coasts along which they move. Sea breezes that blow over warm currents get warmed in turn and absorb moisture. Then they carry the warmth and moisture to neighboring coastal areas.

2.When land borders the ocean, the currents of the ocean warm or cool it, depending on the nature of the particular current that flows by that land. In cases where a warm current flows along a particular coast, that coastal area will generally be warmer than it would otherwise be if it were landlocked.

3.They produce high and low tides along coastal regions.They move vertically pushing warm water and nutrients to the surface along coastal regions.

4.The circumpolar current merges the waters of the Atlantic, Indian, and Pacific Oceans and carries up to 150 times the volume of water flowing in all of the world's rivers.

Three groups of students are given study outlines for 6 weeks. One group studies 2 hours a night, a second group studies 1 hour

katrin2010 [14]

Answer:

The constant here is the study outline

Explanation:

In scientific research, the constant variable is that part/variable of the experiment that does not change or is set not to change. Examples include temperature, environment or height.

Assuming the scenery described in this question is an experiment. All the groups presented are bound by a constant during the experiment. The constant here is the study outline. The study outline provided to the students is not going to change.

NOTE: There could be confusion as regards the answer being the final exam grade but that will be the dependent variable as that will be the outcome of the experiment while the time spent to study will be the independent variable.

A 50 kg diver stands motionless at the top of 10.0 meter high dive. What is her potential energy?

brilliants [131]

Answer:

Potential energy=4905 Joule

Explanation:

Potential energy is defined as the energy between two bodies due to its relative positions. Here one body is the diver and the other body is the earth. So acceleration will be the constant $9.81\ m/s^2$

$P.E.=m\times g\times h\\where\ m=mass\ of\ body=50\ kg\\g=acceleration\ due\ to\ gravity=9.81\ m/s^2\\h=height\ at\ which\ the\ body\ is\ from\ the\ ground=10.0\ m\\\Rightarrow P.E.=50\times 9.81\times 10.0\\\therefore Potential\ Energy=4905\ Joule$
