Answer:

Explanation:

The velocity and acceleration of a skydiver increases as she falls from the plane back to the ground. When she will come more closer to earth the force of gravity will increase on her and her velocity will increase so the acceleration. According to the newtons law of gravitation gravity will increase as the distance between the two body decreases.

What does the SLOPE of a Velocity-Time graph represent? *<br> 1 point
lyudmila [28]

Acceleration

Explanation:

  • In the Velocity-Time graph Velocity is taken in Y-Axis and plotted against Time in X-Axis.
  • The unit of velocity is mentioned in m/s and unit of time is mentioned in seconds.
  • Here we can analyze the instantaneous acceleration and displacement covered.
  • From the slope we can get the body accelerated.
  • From the area under the graph we can get the displacement traveled.
  • We can calculate both average and Instantaneous acceleration from the slope of this graph.

A semicircular plate with radius 6 m is submerged vertically in water so that the top is 2 m above the surface. Express the hydr
dalvyx [7]

Answer: 313920

Explanation:First, we’re going to assume that the top of the circular plate surface is 2 meters under the water. Next, we will set up the axis system so that the origin of the axis system is at the center of the plate.

Finally, we will again split up the plate into n horizontal strips each of width Δy and we’ll choose a point y∗ from each strip. Attached to this is a sketch of the set up.

The water’s surface is shown at the top of the sketch. Below the water’s surface is the circular plate and a standard xy-axis system is superimposed on the circle with the center of the circle at the origin of the axis system. It is shown that the distance from the water’s surface and the top of the plate is 6 meters and the distance from the water’s surface to the x-axis (and hence the center of the plate) is 8 meters.

The depth below the water surface of each strip is,

di = 8 − yi

and that in turn gives us the pressure on the strip,

Pi =ρgdi = 9810 (8−yi)

The area of each strip is,

Ai = 2√4− (yi) 2Δy

The hydrostatic force on each strip is,

Fi = Pi Ai=9810 (8−yi) (2) √4−(yi)² Δy

The total force on the plate is found on the attached image.
