Answer:

While both can cause disease, viruses are not living organisms, whereas bacteria are. Viruses are only "active" within host cells which they need to reproduce, while bacteria are single-celled organisms that produce their own energy and can reproduce on their own. Bacteria serve many vital roles in nature outside of being infectious.

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

vfiekz [6]

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.

Determine the chemical formula for the molecule shown.

OLEGan [10]

Answer: Formula is C4H8O. In every branch of line formula there are Carbon atom. Carbon makes 4 bonds so In branch left in which two CH3-groups are attached there are also an Hydrogen aton which is not shown.

Explanation: Molecule is organic, it is classified as aldehyde.

Hydrocarbons contains only Carbon and Hydrogen atoms, Organic molecules can contain also other atoms.

Reactions of aldehydes are reduction to alcoholes or oxidation to carboxylic acids. It can not for a polymer.
