Work done : 19.5 J
Further explanationGiven
F = 15 N
d = 1.3 m
m = 3 kg
Required
Work done
Solution
Work is the product of force with the displacement of objects.
Can be formulated
W = F x d
W = Work, J, Nm
F = Force, N
d = distance, m
Input the value :
W = 15 N x 1.3 m
W = 19.5 J

Which organelle of a prokaryotic cell contains genetic information?
cell membrane
ribosomes
nucleus
nucleoid
Answer:
The right option is the 4 one. nucleoid
Prokaryotic cells are simple cells that lack a definite nucleus and some membrane-bound organelles. Prokaryotic cells have a nucleoid region, which is an irregularly-shaped central region of the cell that contains the cell’s genetic information (DNA). Other organelles that can be found in prokaryotic cells include plasma membrane, cell wall, cytoplasm, and ribosomes.
Explanation:
Answer:
nucleoid
Explanation:
This is the type of wave that travels in one direction but the energy travels in the opposite direction
Answer:
Transverse wave
Explanation:
A wave is defined as a disturbance along a medium which transfers energy from one point to another.
A wave may be classified as transverse or longitudinal based on the direction of energy transfer relative to the direction of wave motion.
In a transverse wave, energy is transferred in a direction perpendicular to the direction of wave travel. Hence, the direction in which the energy travels is opposite to the direction in which the wave travels.

Give 2 reasons why is copper used for electrial wires
Answer:
Copper electrical wires are safer to use than wires made of most other conductive metals because they are resistant to heat. As you can see, copper is the preferred metal for electrical wires for several reasons. It has high electrical conductive; it's inexpensive; it's ductile; and it's thermal resistant.
What word is the biotic factor in this sentence:
Fish breath oxygen that is dissolved in water.
Answer: Fish
Explanation:
Biotic factor is one of the component of the ecosystem. It is the living component of the ecosystem. It is affected or influenced by the non-living or abiotic components of the ecosystem like water, air, sunlight, and others. Fish is an example of biotic factor which is dependent on abiotic component that is oxygen which is the chief gas required for the breathing. The oxygen is one of the components of the water. So, the oxygen is dissolved in water and the fish acquire the oxygen through water only.
Which choice is a biotic factor of an ecosystem?
A. sun
B. ants
C. air
D. soil

In an ecosystem, deep, cold water is the densest while warm, shallow water is the least dense.
What is an ecosystem?An ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

1pt Which of the following is NOT true about the role tectonic forces play in the rock cycle?
O A. When plates pull apart, rocks melt, and magma forms igneous rocks.
O B. When plates crash together, rocks are buried and form metamorphic rocks.
O c. When plates slide over and under each other, the heat and pressure form igneous rocks.
OD. When rocks push upward and form mountains, the erosion of the mountains can produce sediment.
Tectonic forces do not cause plates to slide over and under each other, to produce heat and pressure which forms igneous rocks
What is the rock cycle?The rock cycle is a cycle which describes how the three basic rock types are related and how earth processes convert one rock type into another over geologic time.
Plate tectonic forces together with weathering and erosional processes, are responsible for the rock cycle.
Tectonic forces play the following roles in rock cycle:
When plates pull apart, rocks melt, and magma forms igneous rocks.When plates crash together, rocks are buried and form metamorphic rocksWhen rocks push upward and form mountains, the erosion of the mountains can produce sedimentTherefore, the statement that when plates slide over and under each other, the heat and pressure form igneous rocks is not True.

When chlorine is added to sodium bromide solution, the mixture turns brown. What type of reaction has taken place?
Answer:
A displacement reaction
Explanation:
This is because the chlorine reacts with the sodium bromide, forcing it to go brown.
I hope this helps, good luck! (✿◡‿◡)
When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine.
What do you mean by Solution?In chemistry, a solution is a homogeneous mixture of two or more compounds in their relative proportions that can be continually altered up to what is referred to as the limit of solubility.
Although the word "solution" is typically used to refer to the liquid state of matter, solutions of gases and solids are also possible.
When chlorine is added to a solution of sodium bromide (either as a gas or dissolved in water), the bromine is replaced by the chlorine. Because chlorine is more reactive than bromine, sodium bromide loses its bromine content. The mixture darkens to brown. The bromine has been displace, giving this colour of brown.

How many cm3 are contained in 3.83 x 107 mm3?
Answer:
3.38 x 10⁴cm³
Explanation:
Given that:
Volume of the substance = 3.83 x 10⁷mm³
The problem entails use to convert from mm³ to cm³;
1000mm³ = 1cm³
So;
3.83 x 10⁷mm³ will produce [tex]\frac{ 3.83 x 10^{7} }{1000}[/tex] = 3.38 x 10⁴cm³
A boy sets up a picnic on the beach next to a sand dune. how are sand dunes formed?
Answer:
Sand dunes are created when wind deposits sand on top of each other until a small mound starts to form. Once that first mound forms, sand piles up on the windward side more and more until the edge of the dune collapses under its own weight.
