STatiana [176]2 years ago
4 0

Answer:

Explanation:

Density = mass/volume

132g/(48.9 cm³) = 2.7 g/cm³

(27 g)/(3 cm³) = 9 g/cm³

512 g/(65 cm³) = 7.9 g/cm³

1.2 kg/(3243 cm³) cm³ = 1200 g/(3243 cm³) = 0.37 g/cm³

If you want to tell a friend about a fish you caught or a tree you cut down,
you're going to tell him WHERE you were ... its position in space, 3 numbers,
'x', 'y', and 'z' ... and also WHEN you were ... its position in time, one more
number. 

Dimensions are numbers used to describe the location of a point, and the
difference in location between two points.  With four numbers, you can exactly
describe the location of anything, and its distance from any other thing, in
space and time.

A tennis racket hits a tennis ball with a force of F=at−bt2, where a = 1290 N/ms , b = 330 N/ms2 , and t is the time (in millise
denpristay [2]

Answer:

The resulting velocity of the ball after it hits the racket was of V= 51.6 m/s

Explanation:

m= 55.6 g = 0.0556 kg

t= 2.8 ms = 2.8 * 10⁻³ s

F= 1290 N/ms * t - 330 N/ms² * t²

F= 1024.8 N

F*t= m * V

V= F*t/m

V= 51.6 m/s
