Answer:
A) ultraviolet light ---> violet light ----> red light-----> infrared light
Explanation:
We know that the electromagnetic spectrum with the wavelength from least to greatest is (also refer attachment)
- gamma ray
- X- rays
- Ultra-violet
- Visible
Violet
Indigo
Blue
Green
Yellow
Orange
Red
Hence the relative order of wavelengths from least to greatest in the electromagnetic spectrum is
A) ultraviolet light ---> violet light ----> red light-----> infrared light
The horizontal component of the velocity is equal to: D. 15 m/s.
<u>Given the following data:</u>
To determine the horizontal component of the velocity:
The horizontal component of the velocity represents the influence of velocity in displacing an object or projectile in the horizontal direction.
Mathematically, the horizontal component of velocity is given by the formula:
Substituting the given parameters into the formula, we have;
Horizontal component, Vx = 15 m/s

Nitrogen
Explanation:
Adding one proton to a carbon atom makes Nitrogen.
A quick introspection on atoms:
- An atom is made up of three fundamental particles.
- They are protons, neutrons and electrons.
- The protons are positively charged and the neutrons do not carry any charges.
- Electrons are negatively charged.
The difference between an atom and another is the number of protons in them. This is the atomic number.
The periodic table of element is a list of elements arranged based on the number of protons they have. Every element on the table has unique number of protons which makes it differ from another.
- Atoms do not readily lose their protons because they are held by nuclear forces in the nucleus of an atom.
When an element gains a proton, it becomes another element.
Carbon has proton number of 6
If a proton is added to it, it becomes 7
This is the proton or atomic number of nitrogen.

Answer:
400 years
Explanation:
The equation that describes the decay of a radioactive sample is:
(1)
where
m(t) is the amount of sample left at time t
is the initial amount of the sample
is the half-life, which is the time taken for the sample to halve
In this problem we have:
is the half-life of Nickel-63
After a time t, the amount of sample left is 6.25% of the original one, which means that
So we can rewrite the equation (1) and solving for t to find the time:
