Which activity directly converts energy from the Sun into chemical energy?

1 answer:

4 0

The biological process that directly converts energy from the Sun into chemical energy would be Photosynthesis. It is a process carried out by autotrophic organisms which are predominantly plants and other photosynthetic bacteria.

The table shows the charges and the distance between five different pairs of objects.

zmey [24]

Answer:

the list of forces from greatest to least is Y, W, X, Z

Explanation:

Given data:

5 pairs of charged plates with force between each pair as : F, W, X,Y, Z

Also given are the charges q1 and q2 of plates in each pair and the distances between them (refer attachment)

To find: to arrange the force from greatest to least.

Initial step is to calculate the force value using the given data of charges and distance between plates.

We know that the force between two charged plates is given by the formula:

F = $\frac{kq1q2}{r^{2} }$

where,

q1 and q2 are charge of the two plates

r is the distance between two plates

k is coulomb constant

Since the problem involves comparison of forces, the k values is not necessarily discussed.

Now we have to calculate force values

F = $\frac{kq^{2} }{d^{2} }$

W = $\frac{2kq^{2} }{d^{2} }$

X = $\frac{kq^{2} }{4d^{2} }$

Y = $\frac{3kq^{2} }{d^{2} }$

Z = $\frac{kq^{2} }{9d^{2} }$

Assume values of q = 1 and d = 2, we get

F = 0.5k

W = 0.5k

X = 0.0625k

Y = 0.75k

Z =0.025k

F and W are though same, the calculated force value shows W = 2F

Hence W is greater than F.

Therefore, the list of forces from greatest to least is Y, W, F, X, Z

Hence answer is : Y, W, X, Z

Question 4. Calculate the kinetic energy of a Year 11 pupil (mass 55Kg)

bogdanovich [222]

Answer:

990 J

Explanation:

Kinetic energy is:

KE = ½ mv²

Given m = 55 kg and v = 6 m/s:

KE = ½ (55 kg) (6 m/s)²

KE = 990 J

How is energy involved in the formation of a covalent bond?

frez [133]

The energy is involved in ionization, electron affinity etc

The following are the conditions that favor the creation of covalent bonds since they are generated by the mutual sharing of electrons:

Electron affinity, first. If both atoms have a strong electron affinity, a covalent link is often preferred between them.

The energy of ionization. The ionization energy of the two atoms participating in the bonding process should be high.

Atomic Dimension. The atoms that form covalent bonds should have lower atomic sizes. Stronger covalent bonds are created when atoms have smaller atomic radii.
Electronegativity. Both atoms' electronegativities ought to be high. The two atoms' electronegativities should differ as little as possible.
In order to establish covalent bonds, the atoms' high ionization energy is involved.
