Answer:

The smaller net force :)

Explanation:

The second law shows that if you exert the same force on two objects of different mass, you will get different accelerations (changes in motion). The effect (acceleration) on the smaller mass will be greater (more noticeable).

If two different net forces are applied to the same object at different times, a smaller net force will cause the object to accelerate at a greater rate.

Force is defined as the push or pulls applied to the body. Sometimes it is used to change the shape, size, and direction of the body. Force is defined as the product of mass and acceleration. Its unit is Newton.

Newton's second rule states that if you apply the same force to two objects with different masses, the accelerations will be different. The impact will be larger on the smaller mass.

If two different net forces are applied to the same object at different times, a smaller net force will cause the object to accelerate at a greater rate.

Hence smaller rate is the correct answer.

Answer:

add add more hot water in the flask painted shiny white while less of it in the one painted Matt black

Explanation:

Let's name the flasks A and B respectively

flask A due to the nature of its exterior will tend to reflect heat from the environment thus will need more hot water while flask B since it painted in Matt black the heat will be absorbed from the environment thus will require less hot water

The current moving through the traditional incandescent light bulb in the examined flashlight is 1.67A.

Electric power is simply the rate at which electrical energy is transferred by an electric circuit per unit time. It is equal to the voltage difference across the element multiplied by the current.

It can be expressed as;

P = V × I

Given the data in the question;

To determine the current moving through the bulb, we substitute our given values into the expression above.

P = V × I

60W = 36V × I

I = 60W / 36V

I = 1.67A

Therefore, the current moving through the light bulb is 1.67A.

Answer:

Explanation:

Part One

Current = 0.6 amps

Voltage = 12 volts

R = ?

R = E / I

R = 12/0.6

R = 20 ohms

Part 2

Rt = Rspeaker + R

Rt = 20 ohms

R = 4 ohms

Formula

Rt = Rspeaker + R

20 = Rspeaker + 4          Subtract 4 from both sides

Rspeaker = 16 ohms

Part 3

Rspeaker = 16 ohms

I = 0.6 ohms

E = 0.6 * 16

E = 9.6

Latent heat can not be detected by a thermometer. The mass of water lost is 0.25 g.

The latent heat is the heat that can not be detected by a thermometer but it acts to break the intermolecular bonds in a substance.

Now we know that;

Heat added = 565 * 10^3 J

Heat of vaporization of water = 2,260,000 J/kg

H = mL

m = H/L

m = 565 * 10^3 J/ 2,260,000 J/kg

m = 0.25 g

Electrolytes are salts or molecules that ionize completely in solution. As a result, electrolyte solutions readily conduct electricity. Nonelectrolytes do not dissociate into ions in solution; nonelectrolyte solutions do not, therefore, conduct electricity

Explanation:

Answer:

Chemical compounds can be divided into two categories according to their ability to conduct electricity through their aqueous solution.
These two categories are electrolytes and nonelectrolytes.

Electrolytes are chemical compounds that can dissolve in water forming ions. These ions can conduct electricity through the solution. Thes include acids, base and salts
Nonelectrolytes are chemical compounds that do not conduct electricity when dissolved in water. This is because they do not form ions when dissolved in water. These include corbon containing compounds, fats & sugars.
The main difference between electrolytes and nonelectrolytes is that electrolytes can get ionized when dissolved in water whereas nonelectrolytes cannot get ionized when dissolved in water.

Answer:

i guess 0.8 miles away

Explanation:

mathematically:-

speed is given in question

Time is given

and we have to find distance

simply by using speed formula (s) = d/t

we get answer

The bolt of  lightning is  0.8 miles far away.

The speed of any moving object is the ratio of the distance covered and the time taken to cover that distance.

Given, is a bolt of lightning and 4 s later we hear the thunderclap. If the speed of sound in air is 0.2 mi/s,

Speed = d/t

D = 0.2 x 4

D = 0.8 miles

Thus, the lightning is  0.8 miles far away.
