which of the following values can you find by calculating the slope of a graph of velocity versus time position . displacement .
statuscvo [17]
The correct answer is: acceleration.

In fact, the slope of the graph of velocity versus time corresponds to the ratio between the variation of v and the variation of t:
\frac{\Delta v}{\Delta t}
But this is exactly the definition of acceleration: a= \frac{\Delta v}{\Delta t}, so acceleration is the correct answer.

How do you find weight =mass×gravitational acceleration
Artist 52 [7]
That's a formula that shows the relationship between three quantities ...
weight, mass, and acceleration.  If you know any two of them, then you
can use this formula to find the one you don't know.

Examples:

==>  I have a rock with 2 kilograms of mass.
        The gravitational acceleration on Earth is 9.8 m/s² .
        How much does my rock weigh on Earth ?

         Weight = (mass) x (grav acceleration)
                      = (2 kg) x (9.8 m/s²)
                                                       =  19.6 newtons
                                                  (about 4.41 pounds)

==>  My brother weighs 770 newtons (about 173 pounds) on Earth.
         What is his mass ?

                               Weight = (mass) x (grav acceleration)

                               770 newtons = (mass) x (9.8 m/s²)
Divide each side
by 9.8 m/s²:           770 newtons / 9.8 m/s² = mass

                                        78.57 kilograms = mass

==> When I went to the Moon, I took along my 2-kilogram rock.
         I weighed my rock on the Moon. 
         It weighs 3.25 newtons  (about 0.73 pound) there.
         What is the gravitational acceleration on the Moon ?

                                   Weight = (mass) x (grav acceleration)

                                   3.25 newtons = (2 kg) x (acceleration)

Divide each side
by  2 kilograms:        (3.25 newtons)/(2 kg)  =  acceleration

                                    1.63 m/s² = grav acceleration on the Moon

Ted lifts a 10N weight at a height of 1.5 m in 1
masha68 [24]

Answer:

D. Ted expanded more power.

Explanation:

Given the following data;

For Ted.

Force = 10N

Height = 1.5m

Time = 1 seconds

To find Ted's power;

Power = workdone/time

But workdone = force * distance

Workdone = 10 * 1.5

Workdone = 15 Nm

Power = 15/1

Power = 15 Watts.

For Johnny.

Force = 10N

Height = 1.5m

Time = 2 seconds

To find Ted's power;

Power = workdone/time

But workdone = force * distance

Workdone = 10 * 1.5

Workdone = 15 Nm

Power = 15/2

Power = 7.5 Watts

Therefore, from the calculations we can deduce and conclude that Ted expanded more power.
