One horsepower (1 hp) is the unit of power based on the work that a horse can do in one second. This is defined, in English unit
nikdorinn [45]

Power is defined as rate of work done which means it is work done in 1 second of time

Now it is given that we have a horse that will give power 745.7 W

So it will do work of 745.7 J in  1 second of time

now if we wish to find the work done by horse in 0.55 s

so we can say

W = Power \times time

W = 745.7 \times 0.55

W = 410.14 J

So it will do total work of 410.14 J in 0.55 s of time

Anestetic [448]

<u>Explanation:</u>

South Africa has the highest amount of people living with HIV/AIDS in the world. It was initially identified in 1982. The ANC came to power in 1994 after ten years of National Party inaction concerning AIDS. The ANC although took province with a formidable strategy, on record at least, for speaking HIV/AIDS.

A National AIDS Convention of South Africa (NACOSA), first gathered in 1992, brought collectively the ANC, the ANC-aligned United Democratic Front, and the National Party government’s ministry of health, to develop a comprehensive 1994 national AIDS plan based on robust projections: ‘HIV/AIDS is emerging as a major public health problem, with over 2,000 reported cases at the end of 1993, and 500,000 people infected with HIV’.

Komok [63]

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
