Answer:

B: The colors of light emitted from heated atoms had very specific energies.

Explanation:

In Thompson's model of an atom the atom is said to be constituted of electrons which are surrounded by a haze of positive charge in order to balance the electrons' negative charges. It is also called plum prodding model because of negatively charged plums which are surrounded by the positively charged pudding.

Now, as the electrons move from higher to lower energy levels a photon which is a particle of light will be given off.

Thus, the correct answer is option B

Answer:

B: The colors of light emitted from heated atoms had very specific energies.

Answer:

1.02 m/s²

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 0 m/s

Final velocity (v) = 6.6 m/s

Time (t) = 6.5 s

Acceleration (a) =.?

Acceleration can simply be defined as the change of velocity with time. Mathematically, it can be expressed as:

a = (v – u) / t

Where:

a is the acceleration.

v is the final velocity.

u is the initial velocity.

t is the time.

With the above formula, we can obtain the acceleration of the car as follow:

Initial velocity (u) = 0 m/s

Final velocity (v) = 6.6 m/s

Time (t) = 6.5 s

Acceleration (a) =.?

a = (v – u) / t

a = (6.6 – 0) / 6.5

a = 6.6 / 6.5

a = 1.02 m/s²

Therefore, the acceleration of the car is 1.02 m/s²

The answer is 388 800 sec

Answer:

388800 secs

Explanation:

1 day = 24 hrs

so 24 times 3 = 72

and 1 hour is equal to 60 min

108 x 60 = 6480

and 60 secs in a minute

6480 x 60= 388800

Answer:

Moisture

Explanation:

The independent variable, in this case, would be the moisture levels of the soils.

The independent variable is the variable being tested. It is the only variable that is altered in the course of an experiment and which has a direct effect on the actual variable that is the main aim of the experiment. All other variables are kept constant while the independent variable is manipulated.

The tomato plants in the two groups were under the same conditions except that a group had more moisture in the soil. Hence, the independent variable is the moisture.

Answer:

The motion of an object can be represented by a position-time graph like Graph 1 in the Figure below. In this type of graph, the y-axis represents position relative to the starting point, and the x-axis represents time

Explanation:

Answer:

V = 24 [V]

Explanation:

To solve this problem we must use ohm's law, which tells us that the voltage is equal to the product of resistance by the current.

V = I*R

where:

V = voltage [V]

I = current [amp]

R = resistance [ohm]

Therefore:

V = 0.4*60

V = 24 [V]

Answer:

C

Explanation:

A free-body diagram shows all the forces exerted or applied on an object.

A free-body diagram includes all the forces exerted on or by the object. Hence, option A is correct.

A free-body diagram is a diagrammatic representation of a single body or a group of bodies that are separated from their surroundings and display all the forces acting on them. A free-body diagram (FBD; sometimes known as a force diagram) is a graphical representation used in physics and engineering to show the applied forces, moments, and consequent reactions on a body under a specific condition.

It shows a body or group of connected bodies along with all the applied forces, times, and reactions that the body experiences. The body could be compact or comprise several interior pieces (like a truss) (such as a beam). To answer difficult problems, a series of free bodies and other diagrams may be required.

Hence, all the forces exerted on or by the object are included in the free-body diagram.

Answer:

76.53 kg; 9.15 m/s² left.

Explanation:

Given the following data;

Weight of car = 750N

Applied force = 700N

a) To find mass

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, [tex] Weight, W = mg[/tex]

We know acceleration due to gravity is equal to 9.8 m/s²

Substituting into the equation;

[tex] 750 = m*9.8[/tex]

[tex]Mass, m = \frac{750}{9.8}[/tex]

Mass, m = 76.53kg

b) To find the acceleration;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex]

Where;

Making acceleration (a) the subject, we have;

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

Substituting into the equation;

[tex]Acceleration (a) = \frac{700}{76.53}[/tex]

Acceleration (a) = 9.15 m/s² left.

Answer in explanation

Explanation:

What we want to do here is to basically put in words in the select pane that could actually beat complete the question.

The higher the distance between the effort and the function of a lever, the higher the force needed to complete the work.

The smaller the distance between the effort force and the fulcrum of a lever, the smaller the mechanical advantage , making the work easier

Answer:

hope the answer helped you. pls mark as brainliest

Explanation:

Newton's second law states that the acceleration an object experiences due to a given force is inversely proportional to its mass, that is --

a=Fm

If the acceleration is 10m/s2 and the object's mass is 2kg , we can use Newton's second law to find that:

10m/s2=F2kg

F=20kg m/s2 , or 20N .

Answer

An object's temperature is the best approximation of the kinetic energy of the particles. When we measure an object's temperature, we measure the average kinetic energy of the particles in the object. The higher the temperature, the faster the molecules of the substance move, on the average

The measure of the warmth or coldness of a substance or an object with reference to some standard value is termed as temperature.

It is a measure of the coldness or hotness expressed in terms of any of the many arbitrary scales and suggesting the direction in which the heat energy will flow spontaneously, that is, from a hotter body to a colder body.

Similar to pressure or density, temperature is an intensive property, which is independent of the quantity of matter being considered.

Thus, temperature refers to a physical quantity, which expresses the extent of coldness or hotness of a substance.
