Answer:
The answer is false
Explanation:
Though the mostly used SI unit of measurement or the most popular units are the
Length,
Time and
Mass
i.e meter (m), seconds (s), kilogram (kg)
Aside all the above stated units for measurements there are other four basic units which are itemized bellow.
they are
1. Amount of substance - mole (mole)
2. Electric current - ampere (A)
3. Temperature - kelvin (K)
4. Luminous intensity - candela (cd)
Answer:
A detailed answer is given in the explanation
Explanation:
<u>FOR CURRENT MEASUREMENT</u>:
In order to measure the current in a component, an <u>Ammeter</u> is used which is included in a multimeter nowadays.
The ammeter is connected in series just before the component by just breaking the circuit at that point and connecting the two terminals of the ammeter to complete the circuit again.
<u>FOR POTENTIAL DIFFERENCE MEASUREMENT</u>:
In order to measure the potential difference across a component, a <u>Voltmeter</u> is used which is included in a multimeter nowadays.
The voltmeter is connected in parallel with the component simply, by connecting the two terminals of the voltmeter across the two ends of the component.
The crystal of potassium chloride has a definite shape because it consists of particles that are held in fixed positions.
Ionic solids are crystalline in nature. This means that the ions that compose them are arranged in an orderly manner to form a crystal lattice.
This crystal lattice is composed of a regular repeating pattern called the unit cell. The ions in these unit cells are held together by strong electrostatic forces.
Hence, the crystal of potassium chloride has a definite shape because it consists of particles that are held in fixed positions.
