Answer:
I think the awnser is B (but don't qoute me on that) if its right then yay but if its wrong im sorry
Explanation:
The work done on the puck is 96 J
Explanation:
According to the work-energy theorem, the work done on the hockey puck is equal to the change in kinetic energy of the puck.
Mathematically:
where
is the final kinetic energy of the puck, with
m = 2 kg being the mass of the puck
v = 10 m/s is the final speed
is the initial kinetic energy of the puck, with
u = 2 m/s being the initial speed of the puck
Substituting numbers into the equation, we find the work done by the player on the puck:

Answer;
1. strong nuclear force
2. electromagnetic force/ electric force
Explanation;
The more protons an element has, the harder it is to bring nuclei together. It takes more energy to trigger fusion in iron and other heavy elements. Lighter elements, such as helium and hydrogen, require less energy to bring about fusion. The sun, for instance, spends most of its life converting hydrogen into helium.
-The strong nuclear force depends on; a more massive the object is the more attractive the force produced and also as distance between objects increases, attractive force decreases at a faster rate.
Even population distribution refers to a type of population distribution in which the arrangement is done in such a way that the distance between neighboring individual is maximized and uniform. This type of population distribution is usually found on the farm land, where the space in which the crops are planted have been carefully measured out. Thus an example of even population distribution is corn planted in a field.
Answer:
The biggest advantage of Solar cookers is their eco-friendliness. By exploitation one you’ll decrease your dependence on gas or electricity, cut back your carbon footprint, and save on fuel and therefore the value of fuel on running home appliances. change of state with star cookers clearly needs daylight, that makes it troublesome to use throughout winter months and on rainy days. change of state conjointly takes a considerably longer time compared to traditional strategies. Users should schedule their change of state time and maximize the employment of daylight. As a result, preparation should begin early within the morning in order that the food may be placed in the cooking utensil by noontide.
