Answer:
People who are in good health at the beginning of a hunger strike "are usually at little risk of dying from malnutrition for at least six to eight weeks," the guidelines state. But people who are ill can die from malnutrition in as little as three weeks. Malnutrition during pregnancy can be quite harmful. Maternal malnutrition during pregnancy can affect the wellbeing and development of the baby. Malnutrition is when the baby and in this case, the mother do not receive adequate nourishment during pregnancy. It means the baby, in the mother’s womb does not get enough nutrients to grow.

A) a vector with all three directions or
dimensions (x,y and z or i, j, k) that are given
B) a vector with only one dimension
C) a vector that has an x and y components that
D) are equal in magnitude
a vector with a magnitude of one
Answer:
A unit vector is (D) a vector with a magnitude of one
Explanation:
Unit Vector Information:
A unit vector is a vector with a magnitude of one. Vectors of different magnitudes can be scaled off the unit vector. Also, they can be used in two, three, or more dimensions.
Other Answers:
A. a vector with all three directions or dimensions that are given
This is the definition of a 3D vector. This is a line segment in three-dimensional space running from point A (tail) to point B (head). Each vector has a magnitude (or length) and direction.
B. a vector with only one dimension
This is the definition of an one-dimensional vector. This type of vector has no dimension, but a number of components, therefore it behaves like a real number.
C. a vector that has an x and y components that are equal in magnitude
(Unsure, I believe this would be defined as an equal vector. Correct me if I'm wrong and I will edit it.)

Calculate the force applied (in newtons) if a pressure of 2000Pa is acting on an area of 3m2.
Our atmosphere exerts a pressure of 14.7 lb/in2. What is the force on one square foot of the earth’s surface caused by the atmosphere
Answer:
The force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.
Explanation:
To force is given by:
[tex]F = P*A[/tex] (1)
Where:
P: is the pressure = 14.7 lb/in²
A: is the area = 1 m²
By entering the above values into equation (1) we have:
[tex]F = P*A = 14.7 \frac{lb}{in^{2}}*\frac{4.45 N}{1 lb}*\frac{1550 in^{2}}{1 m^{2}}*1 m^{2} = 101.4 kN [/tex]
Therefore, the force on one square foot of the earth’s surface caused by the atmosphere is 101.4 kN.

While studying bacterial cells, scientists measure the lengths of the cells in one colony. The chart shows their data. The scientists notice that one measurement stands out. How should the scientists best deal with this measurement? accept it as true and use 85 micrometers in the data when they find the average length accept it as true but say that it is the only cell that has ever been that long consider that there was an error during measuring and collect further data consider that it is possible but very unlikely for these bacterial cells to be so long
Answer:
Following are the solution to the given question:
Explanation:
Its best approach to this measurement ought to be to indicate that there was a mistake throughout the calculation, as well as the gathering of further details while researching cells for bacteria, directly measuring the cell length of a colony. This chart illustrates its data, which scientists have observed that there's still a measurement.

Which of these best describes why your weight would be different on another celestial body?
A. Different celestial bodies have different gravitational pulls
B. The smaller the celestial body, the greater weight
C. The farther the celestial body from the sun, the more the gravitational pull
D. Weight is constant, so it would not change
Answer:
A
Explanation:
The answer is A due to the gravity is stronger the greater the mass but the less the mass is the weaker the gravity. In conclusion, the answer is A because the strength of gravity depends on the mass.
When 560,000 is written in scientific notation, what is the power of 10?

Answer:
False
Explanation:
Low humidity is typically associated with cold temperatures since cold air holds less water compared to warm air. While it is possible for indoor humidity to be as low as 10%, most people generally find humidity levels of about 40 to 45 percent comfortable.

A 0.152 kg ball is attached to a string that is 62.2 cm long. The string will break if subjected to a tension force of 4.8 N. If a small child swings the ball in a horizontal circle around her head, at what velocity will the string break?
Answer:
The value is [tex]v = 3.68 \ m/s[/tex]
Explanation:
From the question we are told that
The mass the ball is [tex]m = 0.152 \ kg[/tex]
The length of the string is [tex]l = 62.2 \ cm = 0.622 \ m[/tex]
The tension of force that will break the string is [tex]T = 4.8 \ N[/tex]
Generally the radius of the circle made by swinging the string is [tex]r = l = 0.622\ m[/tex]
Generally the centripetal force acting on the ball is mathematically represented as
[tex]F_c = \frac{mv^2}{r}[/tex]
Generally this centripetal force is mathematically represented as
[tex]F_c = T - mg[/tex]
=> [tex]T - mg = \frac{mv^2}{r}[/tex]
=> [tex]4.8 - 0.152 * 9.8 = \frac{0.152 * v^2}{0.622}[/tex]
=> [tex]v = 3.68 \ m/s[/tex]

Answer: 0
Explanation:

If I push on the wall with 75 Newtons of force, the wall will push back with 75 Newtons of force.
What is force?Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.
It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.
The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.
