вот ответ на фото ,можно лучший ответ

=0.21м^3

Answer 2

Ответ: 0,21м³

Объяснение:

Дано:

P=5400Н

ρ=2600кг/м³

------------------

V-?

V=m/ρ=P/(gρ)=5400/(10*2600)=0,21м³

Answer 3

Calculating the Volume of a Granite Slab

To find the volume of the granite slab, we can use the formula:

Volume = Mass / Density

Given: - Weight of the granite slab (force): 5400 N - Density of granite: 2600 kg/m^3

Let's calculate the volume using the provided information.

Step 1: Convert Weight to Mass First, we need to convert the weight of the granite slab from Newtons to kilograms. We can use the formula:

Weight = Mass x Acceleration due to gravity

Given: - Weight (force): 5400 N - Acceleration due to gravity: 9.81 m/s^2

Using the formula, we can calculate the mass of the granite slab:

Mass = Weight / Acceleration due to gravity

Mass = 5400 N / 9.81 m/s^2

Mass ≈ 550 kg

Step 2: Calculate Volume Now that we have the mass of the granite slab, we can use the formula for volume:

Volume = Mass / Density

Volume = 550 kg / 2600 kg/m^3

Volume ≈ 0.2115 m^3

So, the volume of the granite slab is approximately 0.2115 cubic meters.

This calculation assumes that the granite slab is a uniform block with a consistent density throughout.

I hope this helps! If you have any further questions or need additional assistance, feel free to ask.

Answer 4

I can help you with your homework question. To find the volume of the granite slab, you need to use the formula:

$$V = \frac{W}{\rho g}$$

where $V$ is the volume, $W$ is the weight, $\rho$ is the density, and $g$ is the gravitational acceleration. Plugging in the given values, we get:

$$V = \frac{5400}{2600 \times 9.8}$$

$$V \approx 0.212 \text{ m}^3$$

The volume of the granite slab is approximately 0.212 cubic meters. I hope this helps.Ответь+подробно.++7.(3+бали)+Знайти+об\'єм+гранітної+плити,+що+має+вагу+5400Н.+Густина+граніту+=2600+кг/м3.​+
