Question

Ke=1/²mv^2 where m=23g v=34m/s

Answer 1

Answer:

Explanation:

For example, venipuncture requires the use of needles typically as large as 22–21 gauge inserted to depths of 25–38 mm to withdraw milliliters of blood. In contrast, vaccines usually require injection of less than 1 ml of fluid and, therefore, 25- to 22-gauge needles with a length of 16–38 mm are adequate.

Answer 2

Answer:

Explanation:1/2*mv²

=1/2*23*34*34=23*17*34=13294
