Answer:

43.2^{\circ}C

Explanation:

The change in temperature of the sample of alcohol is given by:

\Delta T=\frac{Q}{mC_s}

where

Q = 890 J is the amount of heat provided to the sample

m = 16.6 g is the mass of the sample

C_s = 2.47 J/gC is the specific heat of alcohol

Solving the equation,

\Delta T = \frac{890 J}{(16.6 g)(2.47 J/gC)}=21.7^{\circ}C

And since the initial temperature was

T_i = 21.5^{\circ}C

the final temperature is

T_f = T_i + \Delta T=21.5^{\circ}C + 21.7^{\circ}C=43.2^{\circ}C

Answer:

yes every action as an equal and and opposite reaction. if you throw a tool then it will give you a reaction and you will move back.

Explanation:

According to Newton's third law of motion, when two bodies interact between them, appear equal forces and opposite senses in each of them.  

To understand it better:  

Each time a body or object exerts a force on a second body or object, it (the second body) will exert a force of equal magnitude but in the opposite direction on the first.  

So, if you as an astronaut in the described situation throw your tool  in the direction that you are traveling (in the opposite direction of the space station), according to Newton's third law, you will be automatically moving towards the station

bogdanovich [222]

Answer:

One year

Explanation:

In Florida, once you have had your learner's license for 1 year without any traffic convictions, you will receive an intermediate license.

The rule for Florida is that if a driver drives safely without any conviction during that year of his trial, he will receive an intermediate license. This means that he is now completely eligible and safe to drive around Florida's roads.

I hope the answer is helpful.

Thanks for asking.
