Amass of 2000 kg is raised 5.0 m in 10 seconds. what is the power output in horsepower to raise the object?
13
7.5 x 10.^6

The power output in horsepower to raise the object is, P = 13.14 Hp

Explanation:

Given data,

The mass of the object, m = 2000 kg

The object is raised to a height, h = 5.0 m

The time duration of the work, t = 10 s

The force acting on the mass,

                                      F = mg

                                         = 2000 x 9.8

                                         19600 N

The work done on the object is,

                                     W = F x h

                                         = 19600 x 5

                                         = 98000 J

The rate of doing work is defined as the power. It is given by the formula,

                              P = W / t

                                 = 98000 /10

                                 = 9800 Watts

               1 Hp = 745.7 Watts

Therefore,

                            9800 watts = 13.14 Hp

Hence, the power output in horsepower to raise the object is, P = 13.14 Hp

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
