When a rattlesnake strikes, its head accelerates from rest to a speed of 32 m/s in 0.63 seconds. Assume for simplicity that the

only moving part of the snake is its head of mass 200 g. How much (average) power does the rattlesnake need to accelerate its head that fast?

Answer:

Power, P = 162.53 Watts          

Explanation:

Given that,

Mass, m = 200 g = 0.2 kg

Initial speed of the snake, u = 0

Final speed of the snake, v = 32 m/s

Time, t = 0.63 s

Power of an object is given by :

P=\dfrac{W}{t}

P=\dfrac{\Delta K}{t}

P=\dfrac{mv^2}{2t}

P=\dfrac{0.2\times (32)^2}{2\times 0.63}

P = 162.53 Watts

So, the power of the rattlesnake is 162.53 Watts. Hence, this is the required solution.

True or False. Father of a multitude" obeyed God's command to kill His son because the Ten Commandments had not yet been given.
velikii [3]

Answer:

Explanation:

The father of the Multitude was Abraham. And he did precede the 10 commandments. But the story really has nothing to do with the 10 commandments.

He obeyed God's Command because it was God who issued it. Abraham had complete faith in God's ability to make things come out right. The sacrifice of Isaac was a test of faith.

I would advise you to answer true, but whoever wrote the question employed a twisted kind of logic. The sacrifice of Isaac had nothing to do with the 10 commandments. <u><em>Thou Shalt not murde</em></u>r is not really covered by this circumstance.

So true might not be the correct answer. The question is very complex and does not lend itself to a simple True/ False answer.

A small, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely r
NNADVOKAT [17]

Answer;

-it will move away from the large ball because like charges repel.

Explanation;

-Electric force is the force that pushes apart two like charges, or that pulls together two unlike charges. The basic law of electrostatics Like charges of electricity repel each other, whereas unlike charges attract each other.

When small, positively charged ball is moved close to a large, positively charged ball it would be pushed away from the large positively charged ball since they are both positively charged. One has to put in energy to try to move the small ball closer to the large ball. The closer one try to move it to the large ball, the more energy one has to put in, so the more electrical potential energy the small ball would have.
