- Question
What does it mean if a micrograph is false colored?
- Correct Answer
- If a micrograph is false-colored, it means that the computer has created the colour for the object since we know that the electron microscopes sees only black and white colours

Correct Answer: Nuclear energy
Correct Answer: The Basic Speed Law states that you must never drive faster than is safe for present conditions, regardless of the posted speed limit For example, if you are driving 60 kmph in 45 kmph zone, you are not in safe driving and you just not following the speed law
Correct Answer: Scanning tunneling microscopes
Correct Answer: Cinema
Explanation:
Optical illusion is what that refers to persistence of vision with a principle that multiple images blend into a single image in human mind and what is showed in cinema.
Hence, Persistence of vision is the principle behind cinema.
Correct Answer: Stope
Explanation:
These are called intrusive igneous rocks because the magma has intruded into pre-exiting rock layers. Types of intrusive igneous rocks are granite and basalt .
A batholith is the largest of the intrusive bodies.
Correct Answer: All of the above
Explanation:
All of the factors that contribute to global winds are
1) Uneven warming of the earth by the sun
2) Coriolis Effect
3) Convection Cells
Correct Answer: Nearest peak to peak
Explanation:
Wavelength of a wave can be measured with the distance between two nearest crest and crest or nearest troughs. It is measured as armstrong units.
Correct Answer: Hooke's law
Explanation:
When you compress or stretch a spring, as soon as the stress is relieved, the spring attains its normal shape instantly. Its Elastic potential energy helps it do so. Generally, these elastic substances follow the Hooke?s law.
According to this Law, the force needed to change the shape of spring is proportional to the displacement of the spring. The displacement referred here is how far the spring is compressed or stretched from its normal shape. Mathematically, Hook?s Law can be summarised as F= ? k x. Here ?k? is the spring constant and ?x? is the displacement.
Correct Answer: the distance travelled by a vehicle
Explanation:
The odometer or the odograph is an instrument used to indicate the distance travelled by the vehicle.
Correct Answer: convection
Explanation:
Convection is by far the most efficient and common way for heat to be transferred through liquids and gases. It occurs when some regions of a fluid get hotter than others, causing currents in the fluid that move it around to distribute that heat more evenly.
