Answer:
jfonox
Explanation:
since impulse is the change in momentum given by
Impulse = Force x time = change in momentum
I = ft = mv-mu= m(v-u)= jfonox
since the object is initially at rest
u=0,
mv is the final momentum of the object
I =Ft = m(v - 0) = jfonox
mv= jfonox
this show that the final momentum of the object at rest is equal to the impulse received
if any of the mass m, final velocity v or the impact force and the duration of impact of the object is known then we can find or quantify the final momentum.
When alcohol is rubbed on your body, it lowers your skin temperature due to evaporative cooling.
<h3>What is Boiling point?</h3>
The temperature at which the vapor pressure of a liquid is equal to the pressure of the atmosphere on the liquid and varies according to substances and their components.
When alcohol is rubbed on your body, it lowers your skin temperature, it evaporates and is referred to an endothermic reaction which entails absorption by the body.
Alcohol has a very low boiling point which is why rubbing it on the body will lead to evaporative cooling which will produce a cooling effect and is the most appropriate choice.

Answer:
Hello There!!
Explanation:
You use the formula:K.E. = 1/2 m v2.
kinetic energy=1 / 2 × 10 × 5 ²(the power of 2 means you multiply the number by itself)
half of 10 is 5 so you do 5×5².
kinetic energy=5×5²=(5×5=25) so 25×5=125 Joules.
hope this helps,have a great day!!

Answer:SI units are important because these are common to the people of the entire world, so that people from different countries can communicate with each other conveniently regarding business and science. It makes systematic use of prefixes, making it easy to express very large or very small numbers.
