Answer:
Both cause their childrens' deaths
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.
