Answer:
Three, but see below.
Explanation:
You can be certain of three, but that may not be true at all. The only way to know for certain is to put it into scientific notation.
4.05 * 10^5 would be three, but other answers are possible. For example
4.050 * 10^5 would have 4.
Patterns provide a sense of order in what might otherwise appear chaotic. Researchers have found that understanding and being able to identify recurring patterns allow us to make educated guesses, assumptions, and hypothesis; it helps us develop important skills of critical thinking and logic
When the magnitude of all opposing forces is equal, then the force is called balanced. The forces on W and Y are balanced while the forces on X and Z are unbalanced.
<h2>
Net Force:</h2>
It is defined as the vector sum of all forces acting on the object. The forces with the same magnitude in the opposite direction cancel each other.
<h3>Balanced force: </h3>
When the magnitude of all opposing forces is equal, then the force is called balanced.
<h3>Unbalanced force: </h3>
When a force is more than the opposing force, the force is called unbalanced.
Therefore, the forces on W and Y are balanced while the forces on X and Z are unbalanced.

Answer:
D. 10 seconds
Explanation:
All Houston Methodist Hospital buildings employs the use of EPSS(Emergency Power Supply System). This system employs the use of an emergency power generator that turns on to supply emergency power after normal power shuts down within 10 seconds during power outage.
Due to it being used in a hospital the importance of this emergency power system cannot be overemphasized as it is used to provide power supply to hospital equipment such as life support machines etc.
Answer:
i = 0.00077A
Explanation:
Given:
loop radius, r = 3.0 cm = 0.03 m
Area, A = π x r² = π x 0.03² = 0.0028 m²
Magnetic Field, B = 0.75 T
Loop resistance, R = 18 Ω
time, t = 0.15 seconds
Now,
the induced emf is given as:
EMF = - BA/t .......1
Likewise,
EMF = iR.......2
Equate 1 and 2
iR = - BA/t
i = - BA/tR
i = 0.75×0.0028/0.15×18
i = 0.0021/2.7
i = 0.00077A
