Answer:

Explanation:

Element Sulfur has s symbol S in periodic table and has atomic number 16.

It is found in octatomic molecular structure and is a bright yellow crystalline solid at room temperature.

As Sulfur has 8 electrons in outer most shell, it forms only few covalent bond.

It combines with Hydrogen and Oxygen to form molecules of sulfides and Oxides.

Example : Hydrogen Sulfide ( H₂S)

Sulfur Trioxide ( SO₃)

Sulfuric Acid ( H₂SO₄)

A Neglecting air resistance, a ball projected straight upward so it remains in the air for 10 seconds needs an initial speed of

ololo11 [35]

Answer:

The initial velocity is 50 m/s.

(C) is correct option.

Explanation:

Given that,

Time = 10 sec

For first half,

We need to calculate the height

Using equation of motion

$v^2=u^2+2gh$

$h =\dfrac{v^2}{2g}$ ....(I)

For second half,

We need to calculate the time

Using equation of motion

$h =ut+\dfrac{1}{2}gt_{2}^2$

$h=0+\dfrac{1}{2}gt_{2}^2$

$t_{2}=\sqrt{\dfrac{2h}{g}}$

Put the value of h from equation (I)

$t_{2}=\sqrt{\dfrac{2\times v^2}{g^2}}$

$t_{2}=\dfrac{v}{g}$

According to question,

$t_{1}+t_{2}=10$

$t_{1}=t_{2}$

Put the value of t₁ and t₂

$\dfrac{v}{g}+\dfrac{v}{g}=10$

$\dfrac{2v}{g}=10$

$v=\dfrac{10\times g}{2}$

Here, g = 10

The initial velocity is

$v=\dfrac{10\times10}{2}$

$v=50\ m/s$

Hence, The initial velocity is 50 m/s.

A rescue plane flying horizontally at 72.6 m / s spots a survivor in the ocean 182 m directly below and releases an emergency ki

Mila [183]

Answer:

547 m

Explanation:

From law of motion

s = ut + ½at²

Where "t" is Time taken to reach Earth

s= distance= 182 m

a= vertical acceleration = 5.82 m / s 2

U= initial velocity in vertical position = 0

182= ½ × 5.82t²

t²=( 2× 182)/ 5.82

= 364/5.82

= 62.54

t= √62.54

t= 7.908s

horizontal distance travelled = speed x time

Horizontal speed= 72.6 m / s

horizontal distance travelled =72.6× 7.908

= 547 m

Hence, the survivor will it hit the waves at 547 m away

When does carbon dioxide absorb the most heat energy? uring freezing during deposition during sublimation during condensation?

ololo11 [35]

The answer for the given question above would be the third option. Carbon dioxide absorbs the most heat energy during SUBLIMATION. By definition, sublimation is <span>the transition of a substance from the solid to the gas phase without passing through the intermediate liquid phase. Hope this answers your question.</span>
