To Find :

The horizontal range of a projectile launched at 15 degrees to the horizontal with speed of 40 m/s​.

Solution :

The horizontal range of a projectile is given by :

R = \dfrac{u^2 sin 2\theta}{g} ( Here, g is acceleration due to gravity = 10 m/s² )

Putting all value in above equation :

R = \dfrac{40^2 \times sin (2 \times 15)}{10} \ m\\\\R = \dfrac{1600 \times 1}{2\times 10} \ m\\\\R = 80 \ m

Therefore, the horizontal range of projectile is 80 m.

The absolute temperature of a fixed mass of ideal gas is tripled while its volume remains constant. The ratio of the final press
olga_2 [115]

Answer:

3 : 1

Explanation:

The following data were obtained from the question:

Initial temperature (T₁) = T

Initial pressure (P₁) = P

Final temperature (T₂) = 3T

Final pressure (P₂) =..?

Since the volume is constant, we shall use the following formula P₁ /T₁ = P₂ /T₂ to obtain the final pressure. This is illustrated below:

P₁ /T₁ = P₂ /T₂

P/T = P₂ /3T

Cross multiply

T × P₂ = P × 3T

Divide both side by T

P₂ = P × 3T /T

P₂ = P × 3

P₂ = 3P

Therefore, the final pressure is tripled.

Finally, we shall determine the ratio of the final pressure to the initial pressure as follow:

Initial pressure (P₁) = P

Final pressure (P₂) = 3P

Final pressure (P₂) : Initial pressure (P₁)

P₂ : P₁ => 3P/P

P₂ : P₁ => 3 : 1

Therefore, the ratio of the final pressure to the initial pressure is 3 : 1

Electronic configuration of organic compounds <br>​
nadezda [96]

The electronic configuration of organic compounds depends on the orbitals of their atoms and molecules.

<h3>What is electronic configuration?</h3>

The expression 'electronic configuration' makes reference to the spacial arrangement of electrons in distinct energy orbitals of an atom/molecule.

The orbitals are designed with numbers and letters, whereas the amount of electrons in each orbital is expressed as superscripts (e.g., 1s² 2s² 2p² in the C atom that form glucose).

In conclusion, electronic configuration of organic compounds depends on the orbitals of their atoms and molecules.
