Hello. That you forgot to put the answer options. The options are:
Students calculate the coefficient of friction between the block and the surface.
The work done by friction in bringing a block to rest is directly proportional to the initial kinetic energy of the block
The velocity of the block as it slides through the photogais directly proportional to the force exerted on the block during the initial push
The power generated is directly proportional to the force exerted on the block.
Students use the work kinetic energy theorem to calculate the mass of the block
Answer:
The work done by friction in bringing a block to rest is directly proportional to the initial kinetic energy of the block
Explanation:
The options shown above refer to the scientific hypothesis of the experiment shown in the question.
A scientific hypothesis is characterized by an assumption, a possible solution, that a research can present on a given scientific problem. The hypothesis, in other words, is an assumption that will be declared to be true, or false, after it has been tested through scientific experiment.
Answer:
Yes, he provides essential information of the past so that the current inhabitants of the community don't make the same mistakes humanity has made in the past. Without him the world/community would continue a vicious self-destructive cycle.
You must know the population of the state or the census of the state.
