7. If the impact of the golf club on the ball in the previous question occurs over a time of 2 x 10 seconds, what
Kruka [31]

Answer:

3.65 x mass

Explanation:

Given parameters:

Time  = 20s

Initial velocity  = 0m/s

Final velocity  = 73m/s

Unknown:

Force the ball experience  = ?

Solution:

To solve this problem, we apply the equation from newton's second law of motion:

    F  =  m \frac{v  - u}{t}  

m is the mass

v is the final velocity

u is the initial velocity

 t is the time taken

So;

  F  = m (\frac{73 - 0}{20} )  = 3.65 x mass

Calculate the heat energy released when 13.3 g of liquid mercury at 25.00 C is converted to solid mercury at its melting point.C
dmitriy555 [2]

Answer:

-270.321012\ J

Explanation:

C_v = Heat capacity of Hg = 28 J/mol

\Delta T = Change in temperature = (234.32-(273.15+25))

\Delta H_{f} = Enthalpy of fusion = 2.29 kJ/mol

The number of moles is given by

n=13.3\times \dfrac{1}{200.59}\\\Rightarrow n=0.0663\ molHg

Heat is given by

Q_1=nC_v\Delta T\\\Rightarrow Q_1=0.0663\times 28\times (234.32-(273.15+25))\\\Rightarrow Q_1=-118.494012\ J

Heat released is given by

Q_2=-n\Delta H_{f}\\\Rightarrow Q_2=-0.0663\times 2.29\times 10^3\\\Rightarrow Q_2=-151.827\ J

Total heat is given by

Q=Q_1+Q_2\\\Rightarrow Q=-118.494012+(-151.827)\\\Rightarrow Q=-270.321012\ J

The total heat released is -270.321012\ J

Which contribute to both chemical and mechanical weathering? Check all that apply.
larisa86 [58]

organisms and water

Explanation:

Organisms and water contribute to both chemical and mechanical weathering  . A form of weathering known as biological weathering is a derivative of both chemical and physical weathering.

  • Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
  • Organisms are pivotal to both physical disintegration of rocks through their activities.
  • Through their metabolic activities, they also releases chemicals that are used for chemical weathering of rocks.

Water is essential for weathering. It is used in alternate freezing and thawing, a mechanical weathering process to break down rocks.

It is used in rock hydrolysis for chemical weathering.
