When energy (heat) is added to matter the molecules (particles) move _______ and farther ______.
Answers
Answer:
energy
Explanation: transferred from the warmer object to the cooler one. The movement of thermal energy from a substance at a higher temperature to one at a lower temperature is called heat. When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises.

Answer:
The acceleration of the car is
Explanation:
We are assuming rightward coordinate positive and all quantities are along this direction
We know,
where a - acceleration, v=velocity, t=time and x=displacement
multiply by dx in both sides
but we know
Therefore,
Here we integrate both sides with proper limits
x ranges from 0 to 110 as v ranges from 29 to 34
p = 0, r = 110, q = 29, s = 34
a is given as constant thus can be pulled out of the integration
Therefore,
Accelaration of the car is
Note:
Here moving to the right doesn't mean anything significant other than the fact that all quantities are pointing in that direction. Therefore obtained acceleration is also towards the right
If you know equation of motion for constant acceleration as
you can plug in values in this equation to obtain value of a
v - final velocity
u - initial velocity
s - displacement

The spacecraft widely known for it's beautiful images of the gas giants and its moons is the Voyager spacecraft (Voyager 1 & 2). The Voyagers took advantage of a rare opportunity in which all the gas giant planets were aligned that allowed them to get a gravity assist from each planet allowing for extremely close pictures and extremely high speeds on the spacecraft.

Option "D" is the correct answer to the following question.
Explanation:
According to The law of conservation of mass, in a chemical reaction mass neither created nor destroyed.
So,
Total product = Mass of magnesium + Mass of oxygen
Total product = 40 gram + 40 gram
Total product = 80 gram
Therefore, option "D" is the correct answer

Explanation:
Three resistors are found in the diagram. Resistors are represented by a zig-zag line, and they could be light bulbs or a hair dryer.
There are 2 resistors in the circuit. This implies the correct answer is B.
Resistors are components that are commonly used in a circuit. A resistor can be defined as an electrical component that is used in regulating the flow of electrical current in an electronic circuit.
Further Explanation
Resistors can as well be used to provide voltage for transistors. High power resistors are used in the power distribution system and parts of motor control.
Resistors are common components of an electronic circuit and they form an integral part of electronic equipment.
The carbon composition resistors are the most common type of resistor in an electronic device, other types of resistors include
- Fixed resistors: these are the most commonly used type of resistor. They used particularly in an electronic circuit to set the normal conditions in a circuit.
- Variable resistor: these resistors are made up of the element of fixed resistors and a slider. A slider is tapped on the resistor element, which also provides three connections to the component
The fixed resistors are also of different types, and these include
- Carbon composition
- Carbon film
- Metal film resistor
- Metal oxide film resistor
- Wire wound resistor
- Surface mount resistor
Some Other Types of resistor include
- Light-dependent resistor
- Thermistor
- Varistor

Answer:
The loss of balance while standing on a bus often is due:
- The third Newton law.
Explanation:
The third Newton law from Latin says: "Action is always opposed an equal reaction: or the two bodies on each other are always equal, and in opposite directions," which means that when a force is exercised in a direction by a body, the other body in the interaction exercises a force in the other direction. In the case of the person on the bus, when the bus makes a force forward, your body makes a force in the other direction (back), in a similar case, when the bus stops, its force in directed to the back, in that time your body make a force forward, in each case your body can lose balance because your center of gravity is directed in the same direction in which the opposite force to that of the bus moves.
