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.
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.

It follows one prescribed sequence of steps.
B.
It begins and ends with an experiment.
C.
It is used only in Earth and space science.
D.
It can be cyclic.
I need an answer now please....
Answer:
D. It can be Cyclic
Explanation:
Science has all different kinds of alike processes.
The scientific method is a generally and usually a Cyclical Process.
To find the mass of the block of ice, we can use the equation:
Weight = Mass × Acceleration due to gravity
In this case, the weight of the block of ice is given as 520 Newtons. The acceleration due to gravity on Earth is approximately 9.8 m/s².
So, let's plug in the given values into the equation:
520 N = Mass × 9.8 m/s²
To solve for mass, we can rearrange the equation:
Mass = Weight ÷ Acceleration due to gravity
Mass = 520 N ÷ 9.8 m/s²
Calculating this gives us:
Mass ≈ 53 kg
Therefore, the correct answer is C. 53 kg.
The mass of a block of ice that weighs 520 Newtons on Earth is 53 kg.
Therefore, the answer is option c
The weight of an object can be calculated using the formula weight = mass x acceleration due to gravity. In this case, the weight of the block of ice on Earth is given as 520 Newtons. We can use the formula to solve for mass by rearranging it to solve for mass: mass = weight/acceleration due to gravity. Assuming the acceleration due to gravity on Earth is 9.8 m/s², we can calculate the mass as follows:
mass = 520 N / 9.8 m/s² = 53 kg
Therefore, the mass of the block of ice is 53 kg.

The answer is (c) an apple falls to the ground due to gravitational force
Answer:
The sentence that describes the movement of matter and energy in the water cycle is:
C. Energy from sunlight warms the ocean surface and causes water to evaporate.
Explanation:
In the water cycle, energy from sunlight plays a crucial role in causing water to evaporate from the ocean surface. This evaporation process occurs when the sun's energy heats up the water, increasing its temperature. As a result, the water molecules gain enough energy to break free from the liquid state and transform into water vapor, which rises into the atmosphere. This step represents the movement of both matter (water) and energy (sunlight) in the water cycle.
