Which effect are most likely from a hurricane? Check all that apply
const2013 [10]

The correct answers are option - A , B, D and E

Damaged homes due to flooding  

Uprooted trees due to high winds

Eroded coastline due to storm surge  

Damaged personal property due to hail

Reason -

A hurricane when strikes a coastal area causes serious hazards such as heavy rains, high winds, a storm surge, and even tornadoes. A storm surge pushes the sea water on the shore and thus causes flooding near the coast. However heavy rains cause flooding in inland areas. High winds, storm surge, flooding and tornadoes causes damaging of house, personal property and car.

Calculate the molar concentration of HA (90.2 g/mol) in a solution that has a specific gravity of 1.24 and is 64% HNO3 (w/w).​
ser-zykov [4K]

Answer:

Explanation:

Hello,

In this case, considering the given specific gravity we are to compute the density of the 64% HNO3 solution:

\rho=1.24*1g/mL=1.24g/mL

In such a way, since the given solution of nitric acid is 64 % by mass, we've got:

\frac{64gHNO_3}{100g\ solution}

Thus, by using the previously computed density and the molar mass of HA (90.2 g/mol) we can compute the required molar concentration as follows:

M=\frac{(100g-64g)HA}{100g\ solution}*\frac{1.24g\ solution }{1mL \ solution}*\frac{1000mL\ solution}{1L\ solution}*\frac{1molHA}{90.2gHA}   \\\\M=4.95M

Regards.

KE and PE Math
slava [35]

Answer:

1. Answer: The bowling ball has more potential energy as it sits on top of the building. It does not have any kinetic energy because it is not moving.

2. Answer: The bowling ball has equal amounts of potential and kinetic energy half way through the fall. At the half way point, half of the potential energy has been converted to kinetic energy.

3. Answer: Just before the ball hits the ground, it has more kinetic energy. As it hits the ground the potential energy becomes zero.

4. Answer:

PE=784 J

5. Answer:  

PE = 392 J

6. Answer:

KE= 392 J

Also, since the PE and KE are equal at the half way point and PE =392 J, KE = 392 J.

7. What is the kinetic energy of the ball just before it hits the ground?

Answer:  

KE=784 J

At first I answered in the comments, but I am able to answer now. I hope this can help
