any change in the circuit caused by the ammeter, its resistance should ideally be zero.
The voltmeter measures the voltage between two points. It must be connected
between those points, and in parallel with everything between them in the circuit.
In order to avoid any change in the circuit caused by the voltmeter, its resistance
should ideally be infinite.
Final answer:
An ideal ammeter has zero resistance to avoid altering the current it measures, while an ideal voltmeter has infinite resistance to prevent drawing current from the device it's measuring the voltage of.
Explanation:
The resistance of an ideal ammeter is zero ohms. This ensures that it doesn't interfere with the current it is measuring. An ammeter is connected in series with the circuit, and if the resistance were greater than zero, it would decrease the amount of current circulating in the circuit.
On the other hand, an ideal voltmeter has infinite resistance. This happens because a voltmeter is connected in parallel with a device to measure its voltage, and to avoid drawing current from the device, an ideal voltmeter should have infinite resistance.

'Displacement' is the distance between the start-point and end-point,
so the car's displacement is zero, and its average velocity is zero.
However, Speed = (distance covered) / (time to cover the distance).
The car covered a distance of 30 km in 15 minutes,
so its average speed is
(30km) / (0.25 hour) = 120 km/hr.
'Velocity' is not simply a word you use for 'speed' when
you want to sound smarter. They're two different things.

200 x 2 = 400 watts
Answer:
Explanation:
Power = work/time
Work = force x distance
power = force X distance/time (velocity)
power = 200N x 2m/s
power = 400 joules
Answers
So the power is 7 x 110 = 770 W = 0.77kW
0.77 x 13 = 10.01 kWh
10.01 x 10 cents = 100.1 cents (is this 1 dollar? Idk I use a different currency)

Terrane accretion generally occurs along a convergent boundary between a continental plate and an oceanic plate.
Explanation;
Terrane accretion occur at convergent plate boundaries, however, it may be possible for a terrane to be brought from an exotic location along a transform plate boundary.
Additionally, it is also likely for a new divergent plate boundary to develop that rifts a continent apart.

Answer : The correct answer is- citric acid and acetic acid.
Citric acid is a weak organic acid that is found naturally in different types of citrus fruits such as grapes, orange, berries, lemon.
It is used in food to give sour flavour and as a preservative ( such as in gems, pickles) to prevent the growth of bacteria.
Acetic acid is a second simplest carboxylic acid that is a weak organic acid. It is found naturally in fruits such as grapes, pineapple, strawberries. It is safe to eat if used in proper manner ( such as dilute acetic acid, which is vinegar, is used as preservative in food).
Answer: citric acid , acetic acid
Explanation: Acids are substances which when dissolved in water give ions.
The acids are of two types based on their origin:
1. Mineral acids: are inorganic compounds composed of different chemical element combinations. They are synthetically produced in labs and are usually strong. Example: ,
2. Organic acids: are organic compounds essentially composed of carbon and hydrogen atoms. They are found in nature and are generally weak. .
Citric acid is found in citrus fruits and acetic acid
is found in vinegar and are safe to eat.
