Answer:
tge tendence to atract electrons
Explanation:
(a). By the inertia, it's difficult to stop heavier mass than lighter mass.
As, moment of inertia is directly proportional to the mass of the body.
Thus, more force is required to stop the boy with heavier mass than lighter mass.
The problem statement for the given case is,
The time taken by the heavier body to stop swinging is more than the lighter body, then what is the impact of weight on the time period of the swing?
Answer:
D
Explanation:
Acceleration has both magnitude and direction. because velocity is vector quantity
average velocity is vector
linear momentum = mass× velocity
therefore it's also vector
force = mass× acceleration
acceleration is vector therefore force also vector
potential energy= mgh
energy in any form is scaler quantity therefore potential energy too is a scaler quantity.
I believe it is a density change, condensation. but I'm not in college sooo...
Answer:
<h3>Advantages and Disadvantages of Electric Power</h3><h3>Advantages:</h3>
Electric power has many advantages domestically and industrially, as most of the equipment run by electric power. Brightness in the night is only possible by the use of electricity. Almost all the factories and industries are running due to electric power. The advantage of electric power is its reliable and uninterrupted supply runs the equipment efficiently and continuously. The transportation of electricity is easy once the transmission lines are functional. They work for years and need no or very less maintenance. The invention of electric power is one of the best inventions which have changed human life drastically. It allows people to do more leisure activities.
<h3>Disadvantages:</h3>
In the conventional system to generate electric power, coal is burnt to generate heat which boils the water to produce steam. The steam produced is used to run the turbines which in turn generate the electricity. This is a very old method to generate electricity which produces too much air pollution as a by-product. Due to the burning of coal, carbon monoxide, carbon dioxide, different oxides of sulphur and nitrogen are pumped into the atmosphere which pollutes it badly. As carbon dioxide is the greenhouse gas and its excessive presence in the atmosphere raises the earth’s temperature.
Distribution of electric power is in two types of current, AC and DC. Alternating current is 3 to 4 times more dangerous as compared to direct current. It causes more muscle contraction as it reduces skin resistance by stimulating sweating
