Answer:

Chemical change

Explanation:

A chemical change is what happens. The food digested changes smell due to some enzyme the has acted on the food which catalyzes the rate of digestion. The enzymes acts on the food in order to speed up the rate of the reaction (digestion) and in turn causing the smell.

Explain Resistor in parallel and series.

patriot [66]

$\sf\huge\underline\blue{Resistor:-}$

$\rightarrow$ A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.

$\rightarrow$ Resistors reduce the current flow and lower voltage levels within circuits.

$\sf\large\underline\purple{Resistors \:in\: Series:-}$

$\rightarrow$ A circuit is said to be connected in series when the same amount of current flows through the resistors. In such circuits, the voltage across each resistor is different.

$\rightarrow$ In a series connection, if any resistor is broken or a fault occurs, then the entire circuit is turned off. The construction of a series circuit is simpler compared to a parallel circuit.

$\rightarrow$ For the above circuit(attached image-1), the total resistance is given as:

$\sf{R_{total}\: = \:R1 + R2 + ….. + Rn}$

The total resistance of the system is just the total of individual resistances.

$\sf\large\underline\purple{Resistors \:in\: Parallel:-}$

$\rightarrow$ A circuit is said to be connected in parallel when the voltage is the same across the resistors. In such circuits, the current is branched out and recombines when branches meet at a common point.

$\rightarrow$ A resistor or any other component can be connected or disconnected easily without affecting other elements in a parallel circuit.

$\rightarrow$ The figure(attached image -2) above shows ‘n’ number of resistors connected in parallel. The following relation gives the total resistance here

$\sf{\frac{1}{R_{total}}\: = \:\frac{1}{R1} + \frac{1}{R2} + ….. + \frac{1}{Rn}}$

$\rightarrow$ The sum of reciprocals of resistance of an individual resistor is the total reciprocal resistance of the system.

You have decided that you are ready to start a fitness program. Why is it important to set short-term and long-term goals?

suter [353]

Answer:

Setting short-term and long-term goals is very important to stay on track and motivated to improve fitness levels. You can keep track of your progress by weighing yourself every day to track weight loss, and by steadily increasing the difficulty of the exercises to track your strength improvement. It is very important to reflect on progress, so you can evaluate what you need to do in the future to remain on track, as well as seeing how much you've improved.

When the velocity of the car is constant the force of friction is?

miv72 [106K]

..... equal to the force from the engine pushing the car forward.

That's why the car is not accelerating. The horizontal forces on it
are balanced.

Two identical 0.50-kg carts, each 0.10 m long, are at rest on a low-friction track and are connected by a spring that is initial

Keith_Richards [23]

Answer:

The system's kinetic energy changes by 3.6 J

Explanation:

The given parameters are;

The number of cart = 2

The mass of each cart = 0.5kg

The initial length of the spring = 0.50 m

The final length of the spring =T0.3 m

The change in position of the first cart = 0.6 m

The energy given to the first cart = Work done by the force = Force × Displacement

The initial kinetic energy of the two cart moving together = Energy given to the first cart = 6.0 × 0.2 = 1.2J

The kinetic energy given to the two cart combined = The applied force × The total displacement of the two cart as they move together

The kinetic energy given to the two cart combined = 6.0 × (0.6 - 0.2)

The kinetic energy given to the two cart combined = 6.0 × 0.4 = 2.4 J

The total kinetic energy given to the two cart = 1.2 + 2.4 = 3.6 J

The total kinetic energy given to the two cart = 3.6 J

The system's kinetic energy changes by 3.6 J.
