The curved movement of air or water is the result of which of these?Select one:
a. winds spinning off the equator
b. the rotation of Earth on its axis
c. the different air movements north and south of the equator
d. the friction that slows down winds near Earth’s surface

Answers

Answer 1

Answer:

Answer;

B. the rotation of Earth on its axis

Explanation;

The Coriolis effect describes how the Earth's rotation steers winds and surface ocean currents. The Coriolis effect causes the motion of a freely moving object to appear as a curve.
Therefore, since air and water move freely, the Coriolis effect makes their movement to be curved. This is why the movement of winds and oceans does not follow a straight line but it is bent and curved.

Answer 2

Answer: The curved movement of air or water is the result of which of these:
The answer is B

Which option correctly defines the scientific method?a specific way of pursuing a scientific question that involves constructing a theory and then showing it is a law through experimentation
a specific way of pursuing a scientific question that involves constructing a theory and then showing it is correct through experimentation
a specific way of pursuing a scientific question that involves the systematic formulation, observation, testing, and modification of a hypothesis

Answers

The scientific method is a specific way of pursuing a scientific question that involves the systematic formulation, observation, testing, and modification of a hypothesis. Hence, option (C) is correct.

What is scientific method?

Since at least the 17th century, science has been developed using the scientific method, an empirical approach to information acquisition (with notable practitioners in previous centuries; see the article history of scientific method for additional detail.) Given that cognitive presumptions might skew how one understands the observation, it requires careful observation and the use of strong skepticism regarding what is observed.

It entails creating hypotheses through induction based on such observations, testing their testability through experimental analysis and measurement-based statistical testing of the conclusions drawn from the hypotheses, and then revising (or removing) the hypotheses in light of the experimental results. These are scientific method principles, as opposed to a predetermined set of processes that apply to all scientific endeavors.

The force of gravity decreases at a constant rate as we move away from a planet like Jupiter. True or false

Answers

True because when going to Earth from a planet let's say, gravity increase and farther from Earth gravity decreases because the closer you get to the core of Earth, the more it increases

What the core muscles do and why it's important to have a strong set of core muscles.

Answers

Answer:

The core muscles stabilize and protect the spine. They help control all movements and make it possible for us humans to walk and stand up right. The core helps us transfer energy, shift our body weight and reach/move in different directions. It is important to have a strong set of core muscles because it makes everyday activities easier.

What is the zero error of this vernier caliper ???

Answers

I believe the answer is C. 0.14cm.
The zero error in vernier caliper is read by the distance by which the zero of the movable part of the scale is shifted from the zero of the cm ruler in the tool, which is the unmovable part of the tool. The movable part has a scale accuracy of 0.1 cm, while the other has a scale accuracy of 1 cm. And we always use the lowest scale, which is here the 0.1 scale which has greater accuracy with 10 times the 1 cm ruler, to find our errors.

Hope this helps!

Help?? How does the thermal energy of a swimming pool compare to the thermal energy of a lake at the same temperature? A.
Thermal energy is the total potential energy of the particles in a substance. The lake is larger, so it contains more total particles than the swimming pool. The thermal energy of a lake is greater than a swimming pool because the lake is larger.

B.
Thermal energy is the total kinetic energy and potential energy of the particles in a substance. The lake is larger, so it contains more total particles than the swimming pool. The thermal energy of a lake is greater than a swimming pool because the lake is larger.

C.
Thermal energy is the total kinetic energy of the particles in a substance. The lake is more spread out, so it contains fewer total particles than the swimming pool. Therefore, the thermal energy of a lake is less than that of a swimming pool.

D.
Thermal energy is the total potential energy of the particles in a substance. The lake is more spread out, so it contains fewer total particles than the swimming pool. Therefore, the thermal energy of a lake is less than that of a swimming pool.

i think it is B, but can someone help me if im correct or not?
