Answer 2

Answer:

    Mass per metre of the metal bar would be 4.61 kg/m.

Explanation:

• Given that,

The mass of the metal bar = 15kg

The length of the metal bar = 3.25 m

• We want to find the mass per metre of the metal bar.
• Adding two or more numbers means to find their sum or total value. Subtracting one number from another number is used to find the difference between them.
• Multiplication means times or repeated addition. A product is the result of the multiplication of two or more numbers.
• A division is a process of splitting a specific amount into equal parts. It is just opposite to that of multiplication.
• Then we can calculate,

The mass per metre of the metal bar = mass of the metal bar / length of the metal bar

⇒ 15 kg / 3.25 m

⇒ $\frac{15}{3.25}$ = 4.615 ≅ 4.61 kg/m.

• Thus, the mass per metre of the metal bar would be 4.61 kg/m.
