Explanation:

$\implies v_{av} = \dfrac{total \: displacement}{total \: time}$

$\implies v_{av} = \dfrac{100}{10}$

$\implies v_{av} =10 \: {ms}^{ - 1}$

The average diameter of one tennis ball in a package of three is 6.8 cm. Which of the following is the combined volume of all th

Crank

We want to find the combined volume of 3 tennis balls. We will get that the combined volume is 493.7 cm^3

First, remember that for a sphere of diameter D, the volume is:

$V = \frac{4}{3}*3.14*(\frac{D}{2})^3$

Where 3.14 is pi.

Here we know that the average diameter of a tennis ball is 6.8cm, then we can replace that in the above equation to find the volume (in average) of a single tennis ball:

$V = \frac{4}{3}*3.14*(\frac{6.8cm}{2})^3 = 164.5 cm^3$

Now, in 3 balls of tennis, the combined volume will be 3 times the above one, this is:

$3*V = 3*164.5cm^3 = 493.7 cm^3$

The figure shows three displacement vectors, which are

aleksley [76]

Answer:

the correct answer is D

Explanation:

In this exercise, the vectors are in the same west-east direction, so we can assume that the positive direction is east and perform the algebraic sum.

R = δ + ε

where

δ = 2.0 m

ε = 7.0 m

the positive sign indicates that it is heading east

R = 2.0 + 7.0

R = 9.0 m

the direction is east

the correct answer is D
