<span>In physical cosmology, cosmic inflation, cosmological inflation, or just inflation, is a theory of exponential expansion of space in the early universe. The inflationary epoch lasted from 10−36 seconds after the conjectured Big Bang singularity to sometime between 10−33 and 10−32 seconds after the singularity.
I hope this helps!!!

Answer: An ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance. Similarly, an ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter.
Explanation: To find the answer, we need to know about the Ammeter and Voltmeter.
<h3>What is an ammeter?</h3>
- An ammeter is a device, that can be used to measure the electric current flows through a circuit in amperes.
- An ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance when it is connected in series to measure the current.
<h3>What is voltmeter?</h3>
- A voltmeter is a device, that can be used to measure the electric potential difference generated between the terminals of an electric circuit in volts.
- An ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter, when it is connected in parallel to measure the voltage.
Thus, we can conclude that, an ideal ammeter would have zero resistance, because to ensure that, there is no voltage drop due to the internal resistance. Similarly, an ideal voltmeter would have infinite resistance, because to ensure that there is no current is drawn by the voltmeter.

Answer: Baking Soda
A mixture of white vinegar and baking soda in a bowl
will produce a paste that is helpful in removing stains and sanitizing a
dishwasher. To meticulously clean your dishwasher, spread the mixture onto the
build-up crust in the bottom basin of the washer itself then let it sit for
15-20 minutes before running a short cycle using the hottest water. The baking
soda will further absorb the unpleasant odors and will leave your dishwasher
smell fresh.
Answer:
Explanation:
It is given that,
The coordinates of a particle in the metric xy-plane are differentiable functions of time t are given by :
Let D is the distance from the origin. It is given by :
Differentiate above equation wrt t as:
.............(1)
The points are given as, (12,5). Calculating D from these points as :
Put all values in equation (1) as :
So, the particle is moving away from the origin at the rate of 7.076 m/s. Hence, this is the required solution.
