Answer:
15N South
Explanation:
It is 15N South because the two 15N cancel out each other and then you subtract 5N from the 20N and then you get left with 15N. and the 20N is bigger and it is going South.So the answer is 25N south.
Answer:
the answer would be 15N south

Answers
Answer:
They can be replanted.
Explanation:
Renewable sources can be found again and again, similar to how you can plant a tree again to receive food sources and heat production, which in turn is useful to humans.
When The trees are considered a renewable resource because They can be replanted. The correct option is 'B'.
What is a Renewable Resource?
When Renewable sources can be found, again and again, similar to how you can plant a tree again to receive food sources and also heat production, they are in turn useful to humans.
When the renewable resources are resources, generally naturally happening, they can replenish to the rate that they can return the used volume and also be swallowed.
A renewable resource will either produce itself naturally through automatic approaches to that resource or through human interaction and guidance.
Therefore, The correct option is 'B'.

Sam is moving house and is carrying a 300N box of books up a flight of steps 5m high, it takes her 30 seconds. Gary follows her carrying a bag of clothes doing 1000 J of work; it only takes him 25 seconds. Who provides the biggest power? Show your working.
Answers
Answer:
Sam is providing the biggest power i.e. 50 W
Explanation:
Sam is moving house and is carrying a 300N box of books up a flight of steps 5m high, it takes her 30 seconds.
Sam's power :
[tex]P_1=\dfrac{W_1}{t_1}\\\\P_1=\dfrac{F_1d}{t_1}\\\\P_1=\dfrac{300\times 5}{30}\\\\P_1=50\ W[/tex]
Gary follows her carrying a bag of clothes doing 1000 J of work; it only takes him 25 seconds.
Gary's power :
[tex]P_2=\dfrac{W_2}{t_2}\\\\P_2=\dfrac{1000}{25}\\\\P_2=40\ W[/tex]
So, it is clear that Sam is providing the biggest power.

Shawn is doing drills out on the field by pulling a tire behind him for 30 m. If Shawn is applying a net force of
1200 N to pull the tire, then how much work is Shawn doing?
Answers
Answer:
The work done by Shawn in moving the tire is 36,000 J
Explanation:
Given;
net force applied by Shawn , F = 1200 N
distance he moved the tire, d = 30 m
The work done by Shawn in moving the tire is calculated as;
W = Fd
Substitute the given values and solve for Work done;
W = 1200 x 30
W = 36,000 J
Therefore, the work done by Shawn in moving the tire is 36,000 J

You place a book on top of a spring and push down, compressing the spring by 10 cm. When you let go of the book, it is pushed up by the spring. Which statement describes what happens to the energy of the spring book system?
A. The elastic potential energy of the system increases.
B. The gravitational potential energy of the system increases.
C. The kinetic energy of the system decreases.
D. The total energy of the system increases.
Answers
Answer:
Eliminate D as there is no nonconservative force, then look at each energies before and after. The speed of the book will increase, so kinetic energy is increasing. The height of the book is increasing, so gravitational potential energy is increasing. However, since the spring is becoming decompressed, the elastic potential energy is decreasing.

What is the energy transformation that takes place when a jumbo-tron video screen shows an instant replay? A. electrical to light B. mechanical to electrical C. light to chemical D. thermal to sound
Answers
Answer:
A. electrical to light
Explanation:
A jumbo-tron video is a very large television that is most times fitted into walls and displayed along the main roads. It has a light-emitting display(LED) property. Energy transformation is the conversion of energy from one form to another.
The video screen just as a regular television in the house emits light, sound and heat energies. Electrical energy which flows from one end to another powers the jumbo-tron video screen and is thus converted into light, heat and sound energies.
The energy transformation that takes place when a jumbo-tron video screen shows an instant replay is electrical to light energy.
Energy transformation is the conversion of energy from one form to another.
A jumbo-tron video is an electrical appliance that requires electricity to power on. When jumbo-tron video screen shows an instant replay, this shows that the jumbo-tron has been powered on using electricity and converted to light displayed by the video screen.Hence the energy transformation that takes place when a jumbo-tron video screen shows an instant replay is electrical to light energy.

Answers
Answer: Wrong
Explanation:
The statement that accurately describes the relationship between bond strength and the melting and boiling points of a substance is; "substances held together by ionic bonding have higher melting and boiling points than those held together by hydrogen bonding."
Intermolecular forces refers to forces of attraction that holds molecules together in a particular state of matter. The nature and magnitude of intermolecular forces impacts on the magnitude of the melting and boiling points of substances.
Substances held together by ionic bonding have higher melting and boiling points than those held together by hydrogen bonding. The bonds between ionic substances can only be broken at very high temperature.

Answer:B
Explanation:
A P E X
The diagram in which there is no current in the electric wire is B, the reason behind that it is not connected with the battery.
What is Electrical energy?When put in an electromagnetic field, charged matter experiences a force due to the fundamental property of electric charge. Positive or negative electrical ions are possible.
When two charge are in opposition to one another, they repel one another. The term "neutral" refers to an object has no net charge. The early understanding of the way charged particles interact is now referred to as classical electrodynamics, and it is still true for issues that do not demand for taking into account quant phenomena.
Electrical charge is a preserved attribute, meaning that the net charged of an isolated system—that is, the sum of the positive and negative charges—cannot change. Particles at the subatomic level carry an electric charge.
The second diagram from the option will have no current in it because the wires are not connected with the battery, so the flow of current will not take place.
