Answer:

Following are the solution to the given question:

Explanation:

Its best approach to this measurement ought to be to indicate that there was a mistake throughout the calculation, as well as the gathering of further details while researching cells for bacteria, directly measuring the cell length of a colony. This chart illustrates its data, which scientists have observed that there's still a measurement.

Give reasons for the following:
Juliette [100K]

Answer:

a. lower surface area, less resistence

b. more surface area, the load is split so no single tire overstrained

c. more surface area, more resistance against the sand. human steps sink down in the sand.

d. rapid change in air pressure on eardrums lead to somewhat-painful tension

e. air would always find its way in so no pressure difference can be achieved

(would indeed appreciate the brainliest if you appreciate the work)

A square boat made from iron has overall dimensions of 2.00 cm x 11.0 cm x 11.0 cm. It has a mass of 213 g. What is its density?
kupik [55]

<u>Answer:</u> The density of boat is 0.88g/cm^3

<u>Explanation:</u>

To calculate the volume of boat, we use the equation:

V=lbh

where,

V = volume of boat

l = length of boat = 2.00 cm

b = breadth of boat = 11.0 cm

h = height of boat = 11.0 cm

Putting values in above equation, we get:

V=2.00\times 11.0\times 11.0=242cm^3

  • To calculate density of a substance, we use the equation:

\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}

We are given:

Mass of boat = 213 g

Volume of boat = 242cm^3

Putting values in above equation, we get:

\text{Density of boat}=\frac{213g}{242cm^3}\\\\\text{Density of boat}=0.88g/cm^3

Hence, the density of boat is 0.88g/cm^3
