Answer:

The correct answer is A biomass.

Explanation:

Biomass is plant or animal material used for energy production (electricity or heat), or in various industrial processes as raw material for a range of products. It can be purposely grown energy crops (e.g. miscanthus, switchgrass), wood or forest residues, waste from food crops (wheat straw, bagasse), horticulture (yard waste), food processing (corn cobs), animal farming (manure, rich in nitrogen and phosphorus), or human waste from sewage plants.

Burning plant-derived biomass releases CO2, but it has still been <u>classified as a renewable energy source</u> in the EU and UN legal frameworks because photosynthesis cycles the CO2 back into new crops. In some cases, this recycling of CO2 from plants to atmosphere and back into plants can even be CO2 negative, as a relatively large portion of the CO2 is moved to the soil during each cycle.

we measure a voltage difference of 5.0 V between two points on the conducting paper between two parallel conducting electrodes.

Alex17521 [72]

Answer:

E=1824.81 V/m

Explanation:

Given that

Voltage difference = 5 V

Distance ,D= 3 mm

θ = 24°

As we know that electric filed given as

$E=\dfrac{V}{d}$

Given that D is 24° with respect to the perpendicular to the electrodes.So we have to take cos component of D.

d= D cosθ

d= 3 cos24°

d = 2.74 mm

$E=\dfrac{V}{d}$

$E=\dfrac{5}{2.74\times 10^{-3}}$

E=1824.81 V/m

A uniform disk of mass M and radius R has rotational inertia about its central axis of Idisk = 1/2 MR2. A uniform rod of mass m

expeople1 [14]

Answer:

5/6 MR²

Explanation:

In the composite object, the distance from the disk's axis to the rod's axis is R/2. Using parallel axis theorem, the rod's new moment of inertia is:

I = 1/12 MR² + M (R/2)²

I = 1/12 MR² + 1/4 MR²

I = 1/3 MR²

The total moment of inertia is therefore:

I = 1/2 MR² + 1/3 MR²

I = 5/6 MR²

Can you explain hooks law in simple words?

dedylja [7]

Answer:

The extension of a material or a spring is its increase in length when pulled. Hooke’s Law says that the extension of an elastic object is directly proportional to the force applied to it. In other words:

Block B, which has a mass of 4t kg, is moving at a constant velocity across a flat surface. As shown in the diagram, it is being

GrogVix [38]

Block B, which has a mass of 4t kg, is moving at a constant velocity across a flat surface, the magnitude of the force is F=100 N. This is further explained below.

<h3> What is the magnitude of the force?</h3>

Generally, Force is simply defined as a function of mass and time.

In conclusion, A requirement of balance is that the left side exerts the same force as the right, therefore if 100 N is applied to the right, then 100 N must be exerted on the left.
