PART ONE

Physics
1 answer:
Lubov Fominskaja [6]3 years ago
4 0

Answer:

change in momentum is (delta,p))= 2*m*v*sin(23) ,parallel velocity to the window remains unchanged  ignore, perpendicular velocity changes by twice the initial  perpendicular velocity as the hail stone changes direction with respect to the  perpendicular .  force=total(delta,p)/t

hence force=450*2*m*v*sin(23) /46, pressure =force/area=450*2*m*v*sin(23) /46*1.187

This is not fluid mechanics,

Just think about splitting the velocity in to vector components use elastic collision fact is energy is same after collision hence so is the speed ,use known equations.

Which is considered a high-priority health issue in the United State?
Mamont248 [21]

Hello!

I believe C) immunizations are a high-priority health in the United States. First let's talk about what immunizations are. Immunizations are a liquid that is injected into your body by needle. This liquid then enters your blood stream and it gets pumped into all of your body because of your circulatory system. So it spreads all around your body and when you get sick, that vaccine helps to get rid of the disease way quicker or even not at all. The U.S government are in high demand to prevent serious disease by giving people the vaccines because many people are getting sick from, for instance, cancer. Although the actually vaccine cannot cure cancer it can prevent it from happening.

I hope it helps!
