Which situation is most likely to lead to improving a scientific theory?

A. Repeating an experiment to verify results
B. Development of new technologies
C. Increased funding for research
D. Relaxing government restrictions

Answers

Answer 1

Answer:

A. Repeating an experiment to verify results

Explanation:

A scientific theory may be defined as the theory of science that is a thought out explanation of the observations done in the nature or that happens in the natural world. They are constructed using several scientific methods by observing many facts and hypothesis.

According to the question, repeating of an experiment a number of times and verifying its result may help in improving a scientific theory as if we get the similar result for each experiments, then it confirms the basis of the hypothesis or the facts that are observe in the nature and conclude a scientific theory.

The basket ball

Explanation:

The heavier an object is the more kinetic energy it will have even if it is thrown at the same speed; therefore, since the basketball is the heaviest, it is the logical answer.

While a marble is heavy for its size, it would not have the same kinetic energy as the basket ball.

A fighter jet flies 3 km west and then 2 km east in 8 minutes. Determine the jet's average velocity. (Remember to convert!)

Answers

Answer:

7.69km/hr due east

Explanation:

Given parameters:

Displacement due west  = 3km

Displacement due east = 2km

Time taken  = 8 minutes

Unknown:

Average velocity  = ?

Solution:

Average velocity is the rate of change of displacement with time.

  Velocity  = [tex]\frac{displacement}{time }[/tex]

 Displacement is deals with the start and the end;

  Here, displacement  = 3km - 2km  = 1km due east

Time  = 8min

     60min  = 1hr

       8min = [tex]\frac{8}{60}[/tex]   = 0.13hr

 Average velocity = [tex]\frac{1km}{0.13hr}[/tex]   = 7.69km/hr due east

Al inicio de un paseo recorrerá una distancia de 200 km/h, los primeros 120 km lo hará a una velocidad constante de 60 km/h y el resto a una velocidad constante de 90 km/h,¿Cuánto tiempo en horas total durará el viaje?

Answers

Responder:

1 hora 20 min

Explicación:

Paso uno:

datos dados

Durante los primeros 120 km, se nos dice que la velocidad es de 60 km / h.

sabemos que velocidad = distancia / tiempo

por lo tanto, distancia = velocidad * tiempo

deja que el tiempo sea ty la velocidad sea s

distancia = s * t

distancia = 60t -------------------- 1

Segundo paso:

Durante los segundos 80 km, se nos dice que la velocidad es de 90 km / h.

sabemos que velocidad = distancia / tiempo

por lo tanto, distancia = velocidad * tiempo

deja que el tiempo sea ty la velocidad sea s

distancia = s * t

desatancia = 90t ------------------- 2

La distancia total recorrida es de 200 km.

entonces 200 = 60t + 90t

200 = 150t

t = 200/150

t = 1,3 horas

Por lo tanto, el viaje tendrá una duración de 1 hora y 20 minutos aproximadamente.

If the weight of an object on the moon is 1/6 of the weight of an object on earth. What
would be the weight of an object on the moon who has the weight of 4800 N on earth?

Answers

Answer:

1200 N

Explanation:

Answer:

1200N

Explanation:

Suppose a body of mass "m" and its weight on the moon is Wm (where W is the weight and "m" is the moon ;which means weight on the moon).Mass of the moon is "M"

and its radius is "R"

Weight of an object on the moon = "F"(Force)with which the moon pulls.

Wm = GM*m/r2

Weight of the same object on the earth is We(where W is the weight and "e" is the earth; which means weight on the earth).

Mass of the earth is 100 times of that of the moon.

Radius of the moon = R

Radius of the Earth = 4R

Weight of the object on the moon =

We = G100M*m/(4R)2(Pronounced 4 R square)

We = G100M*m/(16R)2(Pronounced 16 R square)

Wm/We = G * M * m * 16R2/R2 * g * 100M * m

=16/100

Therefore, 4800N on earth= 1200N on moon

What would happen to the number of home runs a player could hit if the air was removed from above the field? Use your understanding of Newton's laws to explain.

Answers

Answer:

number of home runs a player would hit would drastically increase

Explanation:

In a hypothetical scenario, if this were to happen the number of home runs a player would hit would drastically increase. When a player hits the ball force is applied to the ball which sends it flying, then the ball meets an opposing force of air resistance and a downward force of gravity which ultimately causes the ball to fall to the ground. This is explained in Newton's first law which states that "objects in motion remain in uniform motion and in a straight line unless they are met by an opposing unbalanced force." Without the force of air resistance, the ball will only be met with a downward force of gravity which would allow it to travel at a much greater distance before hitting the ground, thus resulting in a drastic increase of home runs.

Answer:

number of home runs a player would hit would drastically increase

3. The soccer kicker kicks a 2 kg football with a force of 68 N. How fast will the ball accelerate down the field?
m = _______
a = ________
Fnet = _____

Answers

Answer:

[tex]\boxed {\boxed {\sf m= 2 \ kg , \\a= 34 \ m/s^2, \\\F= 68 \ N}}[/tex]

Explanation:

The formula for force is:

[tex]F=m*a[/tex]

If we rearrange the formula to solve for a (acceleration), the formula becomes

[tex]\frac{F}{m} =a[/tex]

The force is 68 Newtons. Let's convert the units to make the problem easier later on. 1 N is equal to 1 kg*m/s², so the force of 68 N is equal to 68 kg*m/s².

The mass is 2 kilograms.

[tex]F=68 \ kg*m/s^2 \\m= 2\ kg[/tex]

Substitute the values into the formula.

[tex]\frac{68 \ kg*m/s^2}{2 \ kg} =a[/tex]

Divide. Note that the kilograms will cancel each other out (hence why we changed the units).

[tex]\frac{68 \ m/s^2}{2}=a[/tex]

[tex]34 \ m/s^2=a[/tex]

The acceleration is 34 meters per second squared.

Length of table is 1.0m,1.00m and 1.000m.Which one is more accurate?​

Answers

Answer:

1.00 m is a more accurate measured length.

Explanation:

Denote length of the table by L.

For L=1.0 m, there is one significant digit after the decimal.

Care 1: When one more significant digit after decimal considered, the exact number can be from 0.95 to 1.05.

So, the possible span of error [tex]\Delta E_1= 1.05-0.95= 0.1m[/tex]

For L=1.00 m, there is two significant digits after the decimal.

Case 2: When one more significant digit after decimal considered, the exact number can be from 0.095 to 1.005.

So, the possible span of error [tex]\Delta E_2= 1.005-0.095= 0.01m[/tex]

Case 3: For L=1.000 m, there is three significant digits after the decimal.

When one more significant digit after decimal considered, the exact number can be from 0.0095 to 1.0005.

So, the possible span of error [tex]\Delta E_3= 1.0005-0.0095= 0.001m[/tex]

As [tex]\Delta E_1 >\Delta E_2>\Delta E_3[/tex]

So, the least error is in the third case when L=1.00m, hence, L= 1.00m is more accurate.
