balanced rock has a mass of about36,000kg. if the acceleration due to gravity is 9.8 m/s2 what is the force that the rock is exe
drek231 [11]
That means the rock has a downward force due to gravity of 
(9.8)(36,000) = 352,800 N downwards on a free body diagram. If the rock is balanced, that means the normal force up is equal to 352,800 N. And due to Newton's about equal and opposite reactions, if the pedestal is pushing up on the rock with 352,800 N of force, then the rock is exerting 352,800 N of force onto the pedestal.

Wastewater discharged into a stream by a sugar refinery contains 3.40 g of sucrose (C12H22O11) per liter. A government-industry
Ipatiy [6.2K]

<u>Answer:</u> The pressure that must be applied to the apparatus is 0.239 atm

<u>Explanation:</u>

To calculate the osmotic pressure, we use the equation for osmotic pressure, which is:

\pi=iMRT

or,

\pi=i\times \frac{m_{solute}}{M_{solute}\times V_{solution}\text{ (in L)}}}\times RT

where,

\pi = osmotic pressure of the solution

i = Van't hoff factor = 1 (for non-electrolytes)

m_{solute} = mass of sucrose = 3.40 g

M_{solute} = molar mass of sucrose = 342.3 g/mol

V_{solution} = Volume of solution = 1 L

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of the solution = 20^oC=[20+273]K=293K

Putting values in above equation, we get:

\pi =1\times \frac{3.40g}{342.3g/mol\times 1}\times 0.0821\text{ L. atm }mol^{-1}K^{-1}\times 293K\\\\\pi =0.239atm

Hence, the pressure that must be applied to the apparatus is 0.239 atm

Which of the following will increase the strength of a copper electromagnet
Soloha48 [4]

The following will increase the strength of a copper electromagnet;

Adding more loops to the wire

Increasing the current

Explanation:

An electromagnet, a device that transforms electric energy into magnetic energy,  has its magnetic field induced by an electric current. This current must be AC (alternating current) and not Direct Current (D.C) for it to work. Increasing the number of coils in the electromagnet increases the number of field lines of interaction between the current and the paramagnetic material.  Increasing the current also makes the magnetic stronger.
