What is displacement
saveliy_v [14]
This is what wiki says hope it helps
A displacement is a vector whose length is the shortest distance from the initial to the final position of a point P.[1] It quantifies both the distance and direction of an imaginary motion along a straight line from the initial position to the final position of the point.

A displacement may be also described as a 'relative position': the final position of a point (Sf) relative to its initial position (Si), and a displacement vector can be mathematically defined as the difference between the final and initial position vectors:

Explain how the density of a gas is different from the density of a liquid.
zavuch27 [327]

Answer

The same number of particles in a gas spread further apart than in the liquid or solid states.

Explanation:

The same number of particles in a gas spread further apart than in the liquid or solid states. The same mass takes up a bigger volume. This means the gas is less dense. Density also depends on the material.

Mutations can be transmitted to the next generation only if they are present in
emmainna [20.7K]

Answer:

The germline (the gametes)

Explanation:

Mutations are permanent changes in the DNA sequence. They can occur randomly, from mistakes during DNA replication, or as the result of external factors like UV radiation.

For these mutations to be passed on to the next generation, they must be present in the DNA of the gametes(i.e. the egg and sperm cells). This is because this is the DNA that goes on to make the offspring in the next generation following fertilisation.

If mutations are present in somatic cells (i.e. cells other than the gametes), they are not passed on to the next generation. For example, if someone gets mutations in their skin cells as a result of exposure to UV rays, this will not be passed on to their children.

A boat traveled at a constant speed for 5 hours, covering a total distance of 132.3 kilometers. how fast was it going?
Llana [10]
Velocity = distance (m) /time (s)

convert kilometers to metres (132300), substitute into formula.

convert hours to seconds (18000), substitute into formula. it becomes,

132300 divided by 18000 = 7.35 M/S 

always answer questions in the units given in the question.

to get m/s into km/h, multiply by 3.6, therefore it equals 24.46 km/h
