Which currents carry warm water away from the equator?a. deep currents
c. surface currents
b. evaporation
d. freezing Please select the best answer from the choices provided A B C D
Answers
Answer:
Surface currents
Explanation:
The water at the ocean surface is moved by the winds which blows in certain pattern due to earth spin and Coriolis effect.wind is able to move top layer of ocean up to 400 m creating surface ocean current.
Ocean current carry warmth of water to higher Latitudes thus making the climate of that region less chilly.
c. surface currents

What is science?
Science is the methodical, empirically-based pursuit and application of knowledge and understanding of the natural and social worlds.
A method of learning about the world is science. Science allows people to participate in the creation of new knowledge as well as use that knowledge to further their goals. It is both a process, a product, and an institution.
Thus, The first person to observe the planets through a telescope was Galileo Galilei.
Based on relativity, Albert Einstein created a model of the universe.
A technique to determine the separation between celestial bodies was demonstrated by Henrietta Swan Leavitt.
Edwin Hubble demonstrated the expansion of the universe
According to Georges Lemaître, the universe had a beginning.

A Scientific law is a statement that summarizes a pattern found in nature.
Further Explanation:
A fact is a natural observation which remains the same for several repeated testing under the same circumstances. But a fact cannot be considered a law because it could be proven wrong at some point.
A scientific law is also a fact with a wider scope of being true as compared to a fact. An observation is categorised as a scientific law only when it is true in each and every condition and has a larger scope of being true.
A scientific theory is an explanation of a natural phenomenon based on the scientific law by several testing and observations. A scientific theory is not always true and it can change for a phenomenon based on the new evidences found.
A hypothesis is a mere prediction of a situation without any testing and observation. It is simply an idea behind any observation and it is yet to be tested whether it holds true for the condition or not.
Therefore, a scientific law is the one that explains the patterns and observed phenomenon in nature and holds true in every situation.

Subject: Physics
Keywords: Statement that summarizes, pattern found in nature, scientific law, scientific theory, fact, hypothesis, wider scope, always true.
A. scientific law is a statement that summarizes a pattern found in nature. It is describes an observed phenomenon and has predictive power: it can describe what will happen given a set of initial conditions. Often, a scientific law may be expressed as a mathematical equation.
FURTHER EXPLANATION
B. A fact is an observation that is found to be true by repeated testing. Unlike a scientific law, however, a fact has a level of uncertainty. It is only held true until they are proven false. They are also more specific and localized observations compared to scientific laws which are more general and broad in scope.
C. A scientific theory is an explanation for an observed phenomenon. It attempts to explain in detail why and how an observed phenomenon described by a scientific law happens. It is a hypothesis that has been confirmed through time by repeated testing and validation of the scientific community. However, a theory is not set in stone. When new evidence is found that refutes an existing theory, the theory may be changed or abandoned.
D. A hypothesis is a tentative prediction and explanation about the relationship between two variables – the dependent and independent variables. It is a basic idea and has not been tested yet but will soon be subjected to testing to check whether it holds merit based on the data. Hypotheses may be proven valid or not through testing and experimentation.

for this question we have:
Signal 2.0 MHz = Emitted so we can call it
and we need the Reflected =
In this question, we have a source which goes to the heart and a reflected which comes back from the heart and we need the speed of the reflected.
So you should know that the speed of reflected is lower than the source(Emitted).
we also know: ΔBeat frequency(max) = 560 Hz =
so we have:
so frequency of Reflected is:
2.0 × 10^6 Hz - 560 Hz = 1.99 × 10^6 Hz =
now you know that Lambda = v/f
so if we find the lambda with our Emitted then we can find v with the Reflected:
Lambda = 1540(m/s) / 2.0 × 10^6 Hz = 7.7 × 10^-4 m
=>
=> 7.7 × 10^-4m (1.99 × 10^6Hz) = 1532 m/s

between two points. So if you want to measure the difference in electrical potential
between two points, you touch one probe of the meter to each point, and somehow
the internal guts of the meter are able to sense the difference in electrical potential
between the two points.
If the two points have non-reactive impedance (a resistance) between them, then the
difference in electrical potential between the two points, as indicated by the meter,
will be close to (resistance between the two points) x (current flowing between them).
