Mass and velocity are the two terms which affect momentum of a bicycle going hill down.
Explanation:
As we know that Momentum describes the motion of an object. It is the combination of the objects mass and velocity.
So, obviously with no doubt mass and velocity are the two terms which affect momentum.
Momentum(p) = Mass(m) * Velocity(v)
The momentum also depends upon the mass and speed of the object.
More the mass of the object more is the momentum.
Depending upon the gravity and bicycle's motion speed momentum varies.
Bicycle moves faster the down hill if it moves with some speed as it has lesser mass the momentum also will be less.
Answer: C) By collecting run off during the rainy season for future irrigation increases the agricultural production
Explanation:
Water harvesting is a process of collection of rain water by using special water storing systems. This water storage practice helps during the scarcity of water like in dry summer seasons and in conditions of drought. Such water can be treated with filters to make it potable for drinking. But generally the water is used for the purpose of irrigation in the agricultural field and household sanitary requirements.
On the basis of the above description, By collecting run off during the rainy season for future irrigation increases the agricultural production is the correct option.
Farmula 2gh=vf²-vi²
2×0.42×9.81=0²-vi²
8.2404=vi²
Vi=✓8.2404
Vi=2.87m/sec
New sound intensity level after the move is
10 log (1/3²)
= -20 log (3)
= -20 (0.4771) = 9.54 dB LOWER than before the move.
Answer: Explanation:
Carbonated drinks are mixtures of water, sugar, flavorings, and dissolved carbon dioxide gas. They are homogeneous because the ingredients are mixed together to form a consistent liquid.
