The mass is 2.0 kg. If the net force is 20.0 N, what is the acceleration?

Answers

Answer 1
Answer:

Answer:

The answer is 10 m/s²

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

a = (f)/(m) \n

where

f is the force

m is the mass

We have

a = (20)/(2) \n

We have the final answer as

10 m/s²

Hope this helps you

What is a statement that summarizes a pattern found in nature? A. a scientific law B. a fact C. a scientific theory D. a hypothesis

Answers

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.

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.

Answers

If an object is moving or at work, it is considered to be a particle with kinetic energy. In physics, kinetic energy is thought to be the energy of motion, it is an acquisition of energy of an object through the possession of motion. Other forms of kinetic energy are vibration, rotation, and translation.

Answer:

As a person pushes a box across a floor, the energy from the person’s moving arm is transferred to the box, and the box and floor become warm. During this process, energy is conserved.

A ship needs to sail to an island that is 1,000 km south of its starting point. If the captain sails south at a steady velocity of 30 km/h for 30 hours, will the ship make it? a) Yes b) No c) Insufficient information d) Maybe

Answers

No, it will not reach its point. Here is why:

Velocity x time

30 x 30 = 900 km

900 km is not equal to 1,000 km so the ship would have to sail for another 10 hours.

A 1.0 µC test charge travels along an equipotential line a distance of 0.20 cm between two parallel charged plates with a field strength of 500.0 N/C. What is the change in voltage? (µC = 1.0 × 10^-6 C)

Answers


This question is written by a master of deception and distraction.
It's full of so many red herrings that it's tough to walk past it too closely.

In order to answer this question correctly, you don't need to know
the magnitude of the test charge, the distance it travels, or the field
strength between the plates.  The whole question lies in that magic
word "equipotential".

An 'equipotential' line is a path along which the electrical potential
is the same at every point.  It's analogous to a 'contour line' on a
topographic map, or an isobar on a weather map.

A charge moving along such a line uses no energy to travel that path,
and it encounters no change in voltage anywhere in its travels.
