A lorry pulls a trailer at 75 km/h and exerts a uniform pulling force of 800 N on the trailer. Work done is 29995200 Joule and power is 16640 j.
What is work done?Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement.
For a constant force acting in the same direction as the motion, the work is simply equal to the product of the force's magnitude and the distance traveled.
Here, it is given that,
Time = 1800 s
speed = 20.83m/s
Speed = Distance travelled / Time taken
20.83 = s/1800
=37494 m
Work done=Force × displacement
Work done =800x 37494
Work done =29995200 Joule
Power = force x speed = 20.8 x 800 = 16640 J
Thus, Work done is 29995200 Joule and power is 16640 j.

Which of the following characteristics of an object-oriented programming language restricts behavior so that an object can only perform actions that are defined for its class?
Polymorphism
Inheritance
Encapsulation
Programmers who use object-oriented methods consider in terms of a class instance that has its own properties and behaviours, which is how they vary from those who use procedural methods.
Procedural programming tackles applications by managing difficulties using a top-down method where it solves problems from the top of the code and to the bottom, whereas object-oriented programming is known to be one that employs classes and objects. A programming design strategy known as procedural programming attempts to break down clearly specified tasks into modules, functions, etc. In object-oriented programming, objects are only the individual parts of a programme. The (c) Method defines the behaviour of objects. The behaviour of objects is defined through methods, which are merely functions and subroutines.

these usually result from wind and can travel hundreds of miles before they reach the shore. What is that?
Characteristic of a natural phenomenon called a "wind-driven ocean current" or a "wind-driven surface current", usually result from wind and can travel hundreds of miles before they reach the shore.
Wind-Driven Ocean Currents: A Natural Phenomenon with Far-Reaching ImpactsWind-driven surface currents are created by wind blowing over the surface of the ocean, causing the water to move in the direction of the wind. These currents can travel great distances, often for hundreds of miles, before eventually making landfall on a coastline or dissipating.
One example of a wind-driven surface current is the Gulf Stream, which is a powerful, warm ocean current that flows from the Gulf of Mexico up the eastern coast of North America and across the Atlantic Ocean. The Gulf Stream is driven by the prevailing winds and helps to regulate the climate of the eastern United States and Western Europe.
Wind-driven surface currents can have a significant impact on marine ecosystems and coastal communities. They can transport nutrients and plankton, which provide food for marine life, and they can also carry pollutants and debris, which can have negative impacts on coastal environments. Additionally, wind-driven surface currents can affect the movement of ships and boats, as well as the safety of swimmers and other ocean users.

A vertical curve with an equal-tangent crest is intended for 70 mph. The elevation of the high point is 822 feet.
The grade is first +1% and is ultimately +3%. What is the elevation of the curve at station 112+62 if the PVC is at station 110+00? Based on the stopping sight distance (SSD), calculate the design length of the vertical curve: L = KA, L = K X [G1 - G2], K = 247, L = 247 * [ 1- 3] = 494. Calculating the design curve radius is necessary to establish the design speed of an equal-tangent sag vertical curve. To do this, first figure out how long the curve is, which is the distance between the PVC and the PVI (101.77 miles minus 109.09 miles). The design curve radius in feet is then calculated by dividing the elevation difference between the PVC and the PVI (950 ft - 945 ft = 5 foot) by the length of the curve (1.77 mi) and multiplying by 100 (5 ft / 1.77 mi x 100 = 282.6 ft).

To increase the ratio 3:5 by 400, you can simply add 400 to each of the numbers in the ratio. The new ratio would be 403:505.
What is a Ratio?A ratio is a mathematical expression that compares the relative sizes of two or more values.
In ratio 3:5, the first number (3) represents one part and the second number (5) represents another part. These parts can be thought of as parts of a whole, where the whole is equal to the sum of the parts.
When you increase the ratio 3:5 by 400, you add 400 to each of the numbers in the ratio. This results in the new ratio of 403:505, which represents a new relationship between the parts.
The increase in the ratio by 400 means that each part has grown by 400 units, but the relative sizes of the parts have remained the same. The first part is still 3 times smaller than the second part, and the second part is still 5 times larger than the first part.
