Answer:A bow and arrow possesses mechanical energy. When the arrow is drawn it has potential energy and when it is released it produces a force to propel the arrow towards the aimed target, therefore giving the arrow kinetic energy. When you combine both energies it creates mechanical energy.

A gas at 200 K occupies a volume of 350 ml. What temperature is needed to increase the volume

Rudik [331]

Answer: Temperature in constant pressure is 286 K

Explanation: If pressure remains constant, then V/T = constant.

V1 = 350 ml and T1 = 200 K and V2 = 500 ml. V1/T1 = V2/T2

and T2 = T1· V2 / V1 = 200 K · 500 ml / 300 ml = 285,7 K

Artemon [7]

Answer:

$9.8ms^{-2}$

Explanation:

using the equation :

$acceleration = \frac{final velocity - initial velocity}{timetaken} \\ a =\frac{v-u}{t}$

where v is 98m/s

u is 0m/s

t is 10seconds

$a=\frac{98m/s- 0m/s}{10} \\a=\frac{98}{10}\\ a=9.8m/s^{2}$

Answer:

pH=2.34

Explanation:

HBr -> H + Br

The dissociation it's complete, for that reason the concentration of the products is the same of HBr

[H+]=[Br-]=0.00234 M

pH= - log (0.00234)=2.34
