Answer:
numbers
Explanation:
Virtually all unimaginable processes can be described as the movement of certain objects. To analyze and predict the nature of the movements that result from the different kinds of interactions, some important concepts such as momentum, force and energy have been invented. If momentum, force, and energy are known and expressed in a quantitative way (that is, by numbers) it is possible to establish rules by which the resulting movements can be predicted.
Answer:
C : install low-flush toilets
Explanation:
The change in the state of matter causes change in the motion of the particles of the matter. The gaseous state of matter has the greatest speed while the solid state has the least speed.
The change in state of every matter is accompanied by lost or gained of energy.
Example is water.
The solid state of water is ice. The motion of particles of the water is relatively zero because the molecules are held at a fixed position.
The liquid state of water occurs when the temperature of the ice is increased above zero degree Celsius. The speed of the particles of water in liquid state is greater than solid state.
The gaseous state of water occurs when the temperature of the liquid water is increased beyond 100 degree Celsius. The speed of water in gaseous state is greater than liquid state.

Answer: 0.1 Amps
Explanation:
Given that,
heat released (H) = 4800 J
Time taken (T) = 8 minutes
Since the unit of time is seconds, convert 8 minutes to seconds
(1 minute = 60 seconds
8 minutes = 8 x 60 = 480 seconds)
current in the conductor (I) = ?
The conductor resistance (R) = 1kΩ
Convert kilo-Ohms (kΩ) to ohms (Ω)
(If 1000Ω = 1kΩ
1kΩ = 1000Ω)
Now, apply the formula:
H = I²RT
4800J = I² x 1000Ω x 480 Seconds
4800J = 480000Ω•I²
Divide both sides by 480000Ω
4800J/480000Ω = 480000Ω•I²/ 480000Ω
0.01 = I²
To get the value of I, find the square root of I²
I = √0.01
I = 0.1 Amps
Thus, the current in the conductor is 0.1 Amps
