Answer:
The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.
Explanation:
Answer:
55.56 watt
Explanation:
Work (W) = 1000 J
time (T) = 18 sec
power (P) = ?
We know power is the rate of doing work so
p = w / t
= 1000 / 18
= 55. 56 watt
The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.
<h3>What is heating and cooling?</h3>
Heating is the process by which the temperature of a place or substances or object is increased.
Cooling Is the process of lowering the temperature of a substance or object by using conditioners or by freezing .
Therefore, The characteristics shared by both heating and cooling curves is that phases changes when the temperature stays the same.

<u>Out of all given choices, the following statements are true:</u>
- An ammeter is used to measure current.
- A voltmeter is used to measure voltage.
- A voltmeter must be placed in parallel with a resistor to measure the voltage across the resistor.
Options A, E, and F
<u>Explanation:</u>
An instrument by which the current in a circuit is measured is called ammeter whereas an instrument in which voltage is measured in a circuit is called a voltmeter . The ammeter is placed in series with the resistor while the voltmeter is placed in parallel with the resistor.
For the option B, since the ammeter must be placed in series with the resistor to measure current, it is false. Option C is false because an ammeter has zero internal resistance. Option D is also false because a voltmeter has a high internal resistance and is actually infinite.
