If a 5 meter long metal bar has 40 kg mass then what is the mass of a metal bar 3 meters long

hjlf

24 kg

Step-by-step explanation:

You start by calculating the linear mass density of the rod:

d = m/L = (40 kg)/(5 m) = 8 kg/m

So for a 3-m long bar, the mass can be calculated as follows:

m = d×L = (8 kg/m)(3 m) = 24 kg

Work out the value of 2. 4510 ×10to the power of 9 1.15 × 10 to the power of 3

Simora [160]

Answer:

The result in standard form is: $2.3 \times 10^{6}$

Step-by-step explanation:

Dividing the values:

To find the real part, we divide 2.645 by 1.15. So

2.645/1.15 = 2.3

Finding the power:

Its a division, so we keep the base, and subtract the exponents. So

$\frac{10^9}{10^3} = 10^{9-3} = 10^{6}$

Result in standard form:

The result in standard form is: $2.3 \times 10^{6}$
