1. What could be the energy of a flying aeroplane?
2. Is work the same as power?
Answers
Explanation:
The total energy of an aircraft flying in the atmosphere can be calculated using equation 1. [2]
E = ½ m v2 + mgh
A Boeing 737-300 has a maximum takeoff weight of 5.65 × 104 kg, a cruise altitude of h = 10,195 m, and cruise speed of 221 m/sec. Inserting these numbers into the above equation, we obtain 7.03 GJ for the energy at cruise conditions. [3] However, the engines mounted onto the wings of the plane are required to provide additional energy per time, power, in order to keep the aircraft flying at a constant altitude and speed
Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.

Answer
the anser is (C) as 240 Watt
Explanation
As we know that
As given in question
Force = 150 N
Distance = 4m
Then work is
So the answer is 240 watt

The correct answer would be, Socialist system.
Socialist system is another term for a planned economy.
Explanation:
An economic system, in which the economy(including investment, capital and allocation of capital goods) is governed by a predefined economic and production plans, is called as the Planned Economy.
The system of planning in this economic system can either be centralized, decentralized or participatory.
This economic system is regulated by the Government. All decisions about the capital, lands, buildings, machinery, or other resources are taken by the government.
The production, prices, distribution, etc of the products or services are regulated centrally by the government.

Ah hah ! That depends on where he weighs 1250N, because
weight depends not only on mass but also on the local gravity.
So the same mass can have different weights in different places,
and the same weight can indicate different mass in different places.
Weight = (mass) x (acceleration of gravity) .
Note: 1250N is almost exactly 281 pounds.
-- If he weighs 1250N on Mars, then his mass is 336.8 kg.
-- If he weighs 1250N on Earth, then his mass is 127.5 kg.
-- If he weighs 1250N on the Moon, then his mass is 770.2 kg.
