Why do scientists need a standard system of measurement?
djyliett [7]
The answer is so that everyone is measuring the same distance and counting that distance as the same everywhere. one example from real life why it is important to use standard units is the loss of the NASA mars orbiter. some people decided that the units were to be in metric and others thought that the units were in imperial (english) system. so the orbiter was lost.

let's eliminate some choices
A. to allow for consistientcy with measurement data:
not really, just make sure the instruments are accurate.

B. to use tools marked in customary units: this could be true because a custom is something that is accepted in a wide area and if it is standard, then it is customary so b is the answer

C. so they can keep measurement data secret: nope

D. to record with easier abbreviations: not really

the answer is B

Hi please answer and show your work​

Answer:

\huge\boxed{\sf P.E. = 240\ MJ}

\huge\boxed{\sf K.E. = 19.6\ MJ}

Explanation:

<u>Given:</u>

Mass = m = 200,000 kg

Vertical Distance = h = 120 m

Speed = v = 14 m/s

Acceleration due to gravity = g = 10 m/s²

<u>Required:</u>

1) Gravitational Potential Energy = P.E = ?

2) Kinetic Energy = K.E. = ?

<u>Formula:</u>

1) P.E. = mgh

2) K.E. = \displaystyle \frac{1}{2} mv^2

<u>Solution:</u>

1) P.E. = (200,000)(10)(120)

P.E. = 240,000,000 Joules

P.E. = 240 Mega Joules

P.E. = 240 MJ

2) K.E. = 1/2 (200000)(14)^2

K.E. = (100000)(196)

K.E. = 19,600,000 Joules

K.E. = 19.6 MJ

\rule[225]{225}{2}

Hope this helped!

Which statement describes why energy is released in a nuclear fusion reaction based on mass-energy equivalence? For large nuclei
Delicious77 [7]

Answer: Option (c) is the correct answer.

Explanation:

When two or more small nuclei combine together to form a larger nuclei then this process is known as nuclear reaction.

The smaller is an atom, the more energy it requires to release an electron. This energy is known as binding energy.

Thus, when two small nuclei fuse together then there will be more binding energy as compared to when two large nuclei fuse together.

For example, fusion of two hydrogen atoms release more energy then one helium atom, and upon binding excess energy is released into the space.

Hence, we can conclude that energy is released in a nuclear fusion reaction based on mass-energy equivalence because for small nuclei, the binding energy of the lighter nuclei is greater than the binding energy of the heavier nucleus.

If the graph shown is a position-time graph of an object moving at constant velocity, what is the velocity of the object? Assume
belka [17]

Answer:

C.) v = 50 m/s

Explanation:

The relationship between position vs. time graph and velocity is that the derivative (slope) of the position vs. time graph gives you velocity. In other words, find the slope to get the velocity.

Select two arbitrary points. I'll choose (3s, 225m) and (0s, 75m).

Now use the slope equation:

v = \frac{y_{2} - y_{1} }{x_{2} - x_{1}} =\frac{225 - 75}{3-0} = 50 m/s

v = 50 m/s

Hopes this helps!
