PLEASE HELP!!!!!!!!!! Because the boy is slowing down, his velocity decreases over time. Use the final and starting velocities in the data table to calculate his average acceleration. Use the equation , where t is time, ux is initial velocity, vx is final velocity, and ax is acceleration. Use time t = 1.6 seconds, which is calculated using values from the table (1.8 − 0.2).

Answer: The correct answer is option (D).
Explanation:
Voltmeter is a device which measures the the voltage applied across the circuit. It is an electrical instrument used to measure the electric potential between the two points in an electric circuit.
Where as:
A switch is the device which used to connect or disconnect the circuit.
Resistor is a device which opposes the flow of current is an electric circuit.
An ammeter the is an electrical device which measures the amount of current in flowing in amperes in an electrical circuit
Hence,the correct answer is option (D).

Answers
The correct answer of the question is : B) Step-up transformer.
EXPLANATION :
Before coming into any conclusion, first we have to understand the step-up and step-down transformer.
The step-up transformer is the transformer whose transformer ratio is greater than one. It means it will increase the voltage of the source or decrease its current.
On the other hand, the transformer ratio of step-down transformer is less than one. Hence, it will decrease the higher voltage to lower voltage or increase the lower current into higher current of the given source.
As per the question, we want to increase the voltage of the source.
Hence, we have to use step-up transformer.

The small increase in global oil production coupled with an increased demand for those resources leads to a potential imbalance between supply and demand in the oil market.
When global oil production experiences only a small increase while the demand for oil rises, it means that the rate of production growth is insufficient to meet the growing demand.
This situation can have several implications:
Rising oil prices: As demand outpaces supply, the limited availability of oil can lead to an increase in oil prices. When the demand for oil exceeds the available supply, buyers are willing to pay higher prices to secure the limited resources.
Market volatility: Insufficient supply to meet demand can result in market instability and volatility. Fluctuations in oil prices can create uncertainty in the market, affecting businesses, investors, and consumers.

Answer:
The depth is 68.4 meters.
Explanation:
In this question the whale rose to the surface of the ocean to breath and then dives into the ocean at an angle of 20° below the horizontal line. It then travels 200 m straight along this line. We have to determine the depth of the ocean.
The path of the whale forms the hypotenuse of a right triangle and the angle between the hypotenuse and base is given as 20°. Determination of sides or angles in a right triangle can be determines using trigonometry.
sinθ =
opposite side = sinθ
Here θ = 20°
sinθ = sin(20°) = 0.342
opposite side=
Hence the depth is 68.4 m.
Answer:
It is 68.404 m deep.
Explanation:
The motion of the whale can be seen in the form of a right-angle triangle.
Angle of deviation = 20°
We know that, sinФ = Perpendicular/ Hypotenuse.
Here, hypotenuse = 200 m
Depth is perpendicular that we have to find.
sin(20°) = Depth/200
Depth = sin(20°) * 200 = 68.404 meters.

Answer:
B.endangered
Explanation:
Choose "extinct" if the species is extinct and "endangered" if the species is endangered.
Sixty years ago, as few as 20 whooping cranes were left on earth. Now, thanks to conservation efforts, there are more than 300 whooping cranes in the wild.
A.extinct
B.endangered
if there are 20 whooping cranes sixty years ago, and then we have more than 300 today. then it means that the species are endangered
I will go with B
An extinct species no longer exist because there are no offsprings of the parent specie which can give birth to more subspecies .
species no longer exist anywhere on Earth, and once gone they are gone ... on International Trade In Endangered Species like Wild Fauna and Flora (CITES). .... in 1975; the species now numbers more than 1, 000 animals .... whooping cranes, this approach fails to protect most endangered species
Endangered means that the existence is threatened by some human activities, prevailing conditions in the environment or the host it feeds on to survive no longer exists within it reach, hence its survival is at stake
