Answer:

Reha should apply 540 N to lift Neha.

Explanation:

L = 360 N

LD  = 60 m

E =?

ED = 40m

NOW

L * LD = E * ED

360 *60 = E*40

21600/40 = E

540 N = E

If you have 35 ml of gas in a closed container under 1.23 atm of pressure, what will the volume be if the pressure increased to
Over [174]

Answer:

New volume is 14.35 mL

Explanation:

When a system of a gas keeps on constant its temperature and number of moles, the pressure is modified indirectly proportional to the volume:

Pressure increased → Volume decreased

Pressure decreased → Volume increased.

The relation you have to apply is: P₁ . V₁ = P₂. V₂

1.23 atm . 35 mL = 3 atm . V₂

(1.23 atm . 35 mL / 3 atm)  = V₂

V₂ = 14.35 mL

Consider the following reversible reaction. What is the equilibrium constant expression for the given system?
ladessa [460]
The question is incomplete. Complete question is attached below
..........................................................................................................................

Answer: 
Equilibrium constant (K) is defined as the ratio of concentration of product to concentration of reactant.

For the reaction:  2H2O(g)    ↔     2H2(g)      +       O2(g)

Equlibrium constant = \frac{[H_2]^2[O_2]}{[H_20]^2}

[ ] bracket in above expression indicates concentration.

Crystallizing salt from seawater, ripening fruit, and production of elements in the stars are energy/matter changes. These chang
miv72 [106K]

The changes in matter/energy can be classified as follows:

  • Physical changes - Crystallizing salt from seawater
  • Chemical changes - ripening fruit
  • Nuclear changes - production of elements in the stars

<h3>What are physical, chemical and nuclear changes?</h3>

Matter and energy undergo physical, chemical and nuclear changes.

Physical changes are changes in which no new product is formed.

Chemical changes are changes in which no new product is formed.

Nuclear changes are changes in which no new product is formed.

Examples of each of the given changes is as follows:

  • Physical changes - Crystallizing salt from seawater
  • Chemical changes - ripening fruit
  • Nuclear changes - production of elements in the stars

Therefore, matter/energy undergo changes.
