A car travels 14 km due west, then does a
U-turn, and travels 43 km due west.
I. What total distance has the car
traveled?
II.
What is the total displacement of the
car?
III. If the entire trip took 3.20 hours.
determine the average speed of the
car. Give
your answer in both
km hour, and m s. (show
conversion)
IV. If the entire trip took 2.50 hours.
determine the average velocity of
the car. Give your answer in both
km h, and mph (show conversion)
Answers
Explanation:
It is given that,
A car travels 14 km due west, then does a U-turn and travels 43 km due east (when it takes U-turn, it will change direction from west to east)
i. Total distance = total path covered
= 14 km + 43 km
= 57 km
ii. Let east is positive and west is negative.
Displacement = final position-initial position
= 43-14
= 29 km
iii. If time taken in the entire trip = 3.2 hours
Average speed = distance/time
[tex]s=\dfrac{57\ km}{3.2\ h}\\\\=17.81\ km/h[/tex]
1 km/h = 0.2777 m/s
17.81 km/h = 4.94 m/s
iv. If time taken in the entire trip = 2.5 hours
Average velocity = displacement/time
[tex]v=\dfrac{29\ km}{2.5\ h}\\\\=11.6\ km/h[/tex]
1 km/h = 0.621 mph
11.6 km/h = 7.2 mph

Studying neutrinos helped to explain how our Sun works but led to changes in theories of particle physics, how is this process consistent with the scientific process? How can details about a theory be adjusted without undermining other discoveries made through the theory's predictions?
Answers
Explanation:
Yes, evidently, the process is consistent with the scientific process because in scientific process falsification and modification are two very important traits. So this new concept have modified the existing theories.
Through the modification a theory is adjusted without undermining other discovering made through the theory's prediction.
There are many other evidences that prove this fact for example Einstien's Theory of relativity also changes the existing concepts.
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
Answers
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.

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
Answers
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.)
I hope this helps!

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.

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?
Answers
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]

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.
