Atoms found in nature are either stable or unstable. An atom is stable if the forces among the particles that makeup the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. Instability of an atom's nucleus may result from an excess of either neutrons or protons. Ccredits: internet source
Answer:
eukaryotic cells
Explanation:
"Smooth endoplasmic reticulum (sER) is (a part of) endoplasmic reticulum that is tubular in form and lacks ribosomes. It is present in eukaryotic cells and is associated with lipid synthesis, carbohydrate metabolism, regulation of calcium concentration, and drug detoxification"

radiation are represented in waves. Each type of wave has a certain shape and
length. The distance between two peaks in a wave is called the wavelength. It
is indirectly related to the frequency which is the number of wave that pass
per unit of time. Wavelength is equal to the speed of light divided by the
frequency. We calculate as follows:
Wavelength = </span>300,000,000 m/sec / <span>650,000,000,000,000 per second
Wavelength = 4.62x10^-4 m</span>
AM and FM are the two types of modulation that an omnidirectional antenna transmit.
<h3>What is an
omnidirectional antenna?</h3>
An omnidirectional antenna is also referred to as an isotropic antenna and it can be defined as a type of antenna that is designed and developed to radiate equal radio power or intercept radio-frequency (RF), especially in all directions perpendicular to an axis.
In Science, there are two types of modulation that an omnidirectional antenna transmit and this include the following:
- Frequency modulation (FM).
- Amplitude modulation (AM).

Thrust given = 5.26N
Δmass = 12.7g
Δtime = 1.9seconds
exhaust speed = ve
The thrust acting on the rocket is = veΔm/ Δt
So, ve = thrust / (Δm/Δt) = 5.26 x 1.9/12.7 x
ve = 707 m/s
<h3>What is Thrust?</h3>
- Newton's third law uses the concept of thrust to quantitatively quantify a reaction force. A force of similar size and in the opposite direction will be applied to a system when mass is expended or accelerated in one direction.
- Thrust is another name for the force that is exerted to a surface normal to or perpendicular to it.
- The amount required to propel 1 kilogramme of mass at a velocity of 1 metre per second per second is measured as force, and hence thrust, using the International System of Units (SI) in newtons (symbol: N).
