Answer

1. 1cm=10mm, 1kg=1000g and 12in=1 ft

2. 50mm=5cm

    48 in =4ft

     36ft=12 yd

     2.5m=250cm

     1000mL= 1 L

Explanation

if 1cm=10mm then 5cm=?

5×10=50mm

if 12 in =1ft then 48in=?

48/12 =4 ft

if 1m=100cm, then 2.5m=?

2.5×100= 250cm

and when know from capacity that 1000mL is equivalent to 1 liter.

Answer:

1. 50mm, 2. 4ft, 3. 4ft, 4. 250cm, 5. 1L

Explanation:

1. 1cm = 10mm

5cm = y mm = y = (5*10)/1 = 50mm

2. 12in = 1ft

48in = yft

y ft = (48*1) / 12 = 4ft

3. 1ft = 3yd

Z ft = 12yd

Z ft = (12*1)/3 = 4ft

4. 1m = 100cm

2.5m = x cm

X = (100*2.5) / 1 = 250cm

5. 1mL = 1*10⁻³L

1000mL = z L

z L = (1000 * 1*10⁻³) / 1

Z L = 1L

1000mL = 1L.

The deepest trench in the world is 11,000 m in depth. Assuming sea water to have a constant density of 1050 kg/m, determine the
Vanyuwa [196]

Answer:

113406825 N/m²

Explanation:

The pressure at depth of 11,000 m can be calculated by:

Pressure = Atmospheric pressure + Pressure  due to height

Atmospheric pressure = 101325 N/m²

Also,  

P_{height}=\rho\times g\times h

Where,  

\rho is the density of water (\rho=1050\ kg/m^3)

g is the gravitational acceleration = 9.81 m/s²

h = 11,000 m

P_{height}=1050\ kg/m^3\times 9.81\ m/s^2\times 11000\ m

Pressure  due to height = 113305500 N/m²

<u>Pressure = Atmospheric pressure + Pressure  due to height = 101325 N/m² + 113305500 N/m² = 113406825 N/m²</u>

Name the element described in each of the following:
Likurg_2 [28]

A collection of elements in a group share chemical properties.

What is Periodic Table?

The elements are arranged in groups and periods on the periodic table. There is a great deal of chemical similarity between the elements in the same group. Only the number of valence shells is the same for elements that belong to the same period.

Each statement refers to the following elements:

(a) Smallest atomic radius in Group 6A(16) - oxygen

(b) Largest atomic radius in Period 6 - cesium

(c) Smallest metal in Period 3 - Aluminium

(d) Highest IE₁ in Group 4A(14) - carbon

(e) Lowest IE₁ in Period 5 -  Bismuth

(g) Group 3A(13) element that forms the most basic oxide -  Thallium

(h) Period 4 element with filled outer level - krypton

(i) Condensed ground-state electron configuration of [Ne] 3s²3p² - silicon

(j) Condensed ground-state electron configuration of [Kr] 5s²4d⁶- xenon

(k) Forms 2+ ion with electron configuration [Ar] 3d³ - vanadium

(l) Period 5 element that forms 3+ ion with pseudo–noble gas configuration - Indium

(m) Period 4 transition element that forms 3+ diamagnetic ion - Scandium

(n) Period 4 transition element that forms 2+ ion with a halffilled d sublevel - Manganese

(o) Heaviest lanthanide - Lutetium

(p) Period 3 element whose 2- ion is isoelectronic with Ar - sulfur

(q) Alkaline earth metal whose cation is isoelectronic with Kr - Strontium

(r) Group 5A(15) metalloid with the most acidic oxide - nitrogen

1kg of hydrogen is burned in oxygen how much energy is released
Simora [160]

Answer:

121 million joules energy is released

Explain :

As there are 500 moles of hydrogen gas in a kilogram, this means that burning a kilogram of hydrogen gas releases 500 times as much energy or 121 million joules .

A cup of coffee (140g) cools from 75°C down to comfortable room temperature 20°C. How much energy does it release to the surroun
Thepotemich [5.8K]

Given that the mass of coffee in the cup = 140 g

Final temperature = 20^{0}C

Initial temperature = 75^{0}C

Let us assume the specific heat of coffee is equal to that of water = 4.184\frac{J}{g^{0}C }

Temperature change = T(final) - T(initial) = (20 - 75 )^{0}C

                                                                   =- 55 ^{0}C

-Heat given out by coffee = heat absorbed by the surroundings

Heat released into the surroundings =-(mC(T_{final}-T_{initial}))

                                             = -(140g)4.184\frac{J}{g^{0}C }( -55^{0}C)

                                             = 32,217 J
