The Humus or the topsoil present in the soil is the biggest source of nitrogen for the plants as it is formed from organic material of leaves and animals.

Explanation:

The soil is made up of several components that are present in different proportions. The quality of the soil depends on the amount of a particular substance present in the soil.

The fertility of soil is determined by the amount of minerals present in the soil. the organic materials present in the soil play the important role in meeting different requirements of the plants as they grow.

The nitrogen is one of the most important requirement of the plant as they grow. The requirement of the nitrogen for a plant is fulfilled by the organic compounds present in the upper layer of the soil.

This upper layer of the soil is rich in organic components and it is called as the humus. The other parts of the soil like clay, silt etc. are not rich in the organic components. So, they cannot supply sufficient nitrogen to the plants.

Thus, the Humus or the topsoil present in the soil is the biggest source of nitrogen for the plants as it is formed from organic material of leaves and animals.

Okay so I understand none of this. Can someone please explain how to do this to me?

According to newtons 3rd law, every force has an equal and opposite force, which means that the answers for a and b should be the same.
you might be knowing the equation of F which is

F = G(m1)(m2)/(r^2) (<em> this formula may be wrong, look it up on google)</em>
G is the universal gravitation constant, just google for the exact value, the value should be something like 6.67E-11
m1 is the mass of an apple
m2 is the mass of an orange
r is the distance between them ( should be squared)

A positive point charge (q = +5.45 x 10-8 C) is surrounded by an equipotential surface A, which has a radius of rA = 1.49 m. A p

ruslelena [56]

Answer:

$r_{B} = 3.34\ m$

Solution:

As per the question:

Point charge, q = $5.45\times 10^{- 8}\ C$

Test charge, $q_{o} = 4.96\times 10^{- 11}\ C$

Work done by the electric force, $W_{AB} = - 9.05\times 10^{- 9}\ J$

Now,

We know that the electric potential at a point is given by:

$V = \frac{kqq'}{r}$

where

r = separation distance between the charges.

Also,

The work done by the electric force i moving a test charge from point A to B in an electric field:

$W_{AB} = kqq_{o}(\frac{1}{r_{B} - \frac{1}{r_{A}}}$

$- 9.05\times 10^{- 9} = 9\times 10^{9}\times 5.45\times 10^{- 8}\times 4.96\times 10^{- 11}(\frac{1}{r_{B}} - \frac{1}{1.49}}$

$- 0.3719 = (\frac{1}{r_{B}} - 0.67}$

$r_{B} = \frac{1}{0.299} = 3.34\ m$

A large block attached to a spring is undergoing simple harmonic motion horizontally, with angular frequency ω and amplitude A.

Naily [24]

Answer:

Explanation:

It is a problem based on simple harmonic motion and friction . maximum friction possible between large block and mass m is µ mg . During SHM , maximum acceleration is ω² A and force is mω² A .

friction must exceed it so that mass m may not slip over it during motion . so

µ mg ≥ mω² A

µ ≥ mω² A / mg

smallest value of µ

= mω² A / mg

= ω² A /g

Which statement is an example of determining the relative age?

const2013 [10]

knowing the age of a grandmother because she was a kid during the Great Depression

Explanation:

The best example for relative age is simply knowing the age of a grandmother because she was a kid during the Great Depression. Relative age is usually based on the occurrence of a popular and world wide event. It is not an absolute age that gives numerical and quantitative values to age.

The reference here is the Great Depression
The Grandmother was kid during this period in time.
We can use this knowledge to infer her age.
Since she was a kid at that point, her current age would how far back the depression was and an estimate of her age at that time.
