4. True
5. The amplitude of the ripples decreases as the circumference of the circle increases.
<h3>What is a wave?</h3>
A wave is a disturbance that moves energy from one place to another.
Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation. Electromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each travelling in a wave-like pattern at the speed of light. Hence, the statement is true.
As the disturbance moves outwards the energy it carries is spread over a larger and larger region called the wavefront. For example, the ripples in the water lie in a circle with an ever-increasing circumference. The amplitude of the ripples decreases as the circumference of the circle increases.

Your general impression suggests that your immediate action should be to call for additional help. The correct option is a.
<h3>What is immediate action?</h3>
Immediate actions are the actions that are taken without taking any time. These actions are taken when there is no time to think, and you should immediately think about the actions. The emergency condition needs immediate help.
During the time of general impression, one should immediately call for additional help. Additional people will give you suggestions for the problem.
Thus, the correct option is a. call for additional help.

Hello!
The formula is density = mass / volume
=> volume = mass / density
volume = ?
mass = 2500.0 g
density = 10.5 g/cm3
volume = mass / density
volume = 2500.0 g / 10.5 g/cm3
volume = 2380.95 cm3
Hope this help!
Explanation:
The given molecule is
H3C - C ≡ C - CH3
The numbering order is shown below:
H3C - C ≡ C - CH3
1 2 3 4
So, the alkyne group is in the second position.
The carbon chain has four carbons.
Hence, the IUPAC name of the given compound is:
2-butyne.
Answer:
232 g CO2
2 C8H18 + 25 O2 --> 16 CO2 + 18 H2O
75.3 g C8H18 (1mol / 114.26g) (16 mol CO2/2 mol C8H18) (44.01 g/1 mol) = 232 g
Hope this helps!
