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.

10km/hr or 80mph is the possible answer I can give
Answer:
Explanation:
Given a ball of mass m= 0.5kg
The ball moves in as circle of radius r= 0.4m
Speed of the ball is v = 4m/s
Centripetal force is exerted on ball and it is given as
Fc = m•ac
ac is centripetal acceleration and it is given as
ac = v²/r
Then,
Fc = mv²/r
Fc = 0.5 × 4²/0.4
Fc = 20N.
The force exerted on the ball is 20N
Answer:
V₂= 1 L
Explanation:
Given that
Volume occupies V₁= 6 L
Initial pressure = P₁
Initial temperature = T₁
The final pressure =P₂ = 2 P₁
Final volume =V₂
Final temperature = T₁/3
As we know that equation for ideal gas
P V = m R T
P=pressure, V=volume, T=temperature
m=mass ,R=gas constant
Now from mass conservation
![m=\dfrac{P_1V_1}{RT_1}=\dfrac{P_2V_2}{RT_2}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7BP_1V_1%7D%7BRT_1%7D%3D%5Cdfrac%7BP_2V_2%7D%7BRT_2%7D)
![\dfrac{P_1V_1}{RT_1}=\dfrac{P_2V_2}{RT_2}](https://tex.z-dn.net/?f=%5Cdfrac%7BP_1V_1%7D%7BRT_1%7D%3D%5Cdfrac%7BP_2V_2%7D%7BRT_2%7D)
![\dfrac{P_1\times 6}{RT_1}=3\times \dfrac{2P_1V_2}{RT_1}](https://tex.z-dn.net/?f=%5Cdfrac%7BP_1%5Ctimes%206%7D%7BRT_1%7D%3D3%5Ctimes%20%5Cdfrac%7B2P_1V_2%7D%7BRT_1%7D)
6 = 3 x 2 V₂
V₂= 1 L
So the final volume will be 1 L
