Answer:

The top of the block has an area of 0.25m².

i) a Calculate the pressure on the top face of the block.

ii) The atmospheric pressure is 1.0 × 10⁵ Pa.

Calculate the pressure on the top face of the block due to the depth h of water.

iii) The density of sea water is 1020kg/m³.

Calculate the depth h.

Answer:

P=F/A, P is for pressure, F is for force, and A is for area, I can't really see half of the picture so I don't know the figures but just substitute them in and rearrange the equation if you have to. Good luck :))

Lorico [155]

The change or mutation in a segment of DNA after replication may lead to changes in the genotype, the traits of the organism and the proteins (option i, ii and iii).

<h3>What is a genetic mutation?</h3>

A genetic mutation is any change in the nucleotide bases of the genome of an organism that may be associated with modifications in the phenotypic traits or features of the organism if this change alters the expression of a given gene that produces a particular protein.

Mutations may be neutral when they don't show an apparent effect on the phenotype of an organism such as occur in mutations located in intergenic regions.

Therefore, with this data, we can see that a genetic mutation may alter the proteins produced by an organism which has a direct effect on the phenotype by altering the structures that it is able to synthesize.

Answer:

<h2>117.6 J</h2>

Explanation:

The gravitational potential energy of a body can be found by using the formula

GPE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 9.8 m/s²

From the question we have

GPE = 6 × 9.8 × 2

We have the final answer as

<h3>117.6 J</h3>
