Which of the following is the best description of the term resultant
displacement?
A. The scalar that joins all the points along the path.
B. The average of all the displacement vectors.
C. The total distance traveled.
O D. The shortest distance from the beginning point to the end point.
Answer:
D
Explanation:
Displacement refers to the shortest, or straight-line path from one point to another. It is a vector, thus A is incorrect. It is not the average, but rather the sum of all displacement vectors, so B is incorrect. It is not the distance traveled, as some paths have longer distances than others, while leading to the same destination, hence same displacement. (i.e. running around in circles yields positive distance traveled but zero displacement.)
Answer:
Explanation: D
Displacement is a vector. It has direction and it has magnitude. But we are asked for the resultant displacement. You have to use pythagorean theorem. This makes our answer always positive. That essentially means distance, since you did just do the distance formula.
A is wrong because that tells you perimeter
B is wrong because that tells you the midpoint
C is wrong because displacement and distance are two different things. We dont want the distance of the two vectors
D is correct, this perfectly explains the distance formula
A spherical mirror and a thin spherical lens have each a focal length of +10cm , the mirror and the lens are likely to be
Answer: Concave mirror and convex lens
Explanation: A spherical mirror and a thin spherical lens have each a focal length of +10cm, this means that distance of any object from the mirror is +10 metres.
While for the lens, the distance of any object to the other side of the lens is +10 metres. Therefore, the mirror is concave mirror and the lens is a convex lens.

Identify that all objects exert a force of gravity on all other objects in the universe
Answer:
It's like the Earth pulling on you and keeping you on the ground. That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects.

Answer:
11.) g = 3.695 m/s^2
12.) g = 8.879 m/s^2
13.) E = 8127 N/C
Explanation:
11.) Given that the
Mercury mass M = 3.3 × 10^23kg
Radius r = 2.44 ×10^6 m
Gravitational constant G = 6.67408 × 10^-11 m3kg-1 s^-2
Gravitational field strength g can be calculated by using the formula below
g = GM/r^2
Substitutes all the parameters into the formula
g = (6.67408 × 10^-11 × 3.3 × 10^23)/(2.44×10^6)^2
g = 2.2×10^13/5.954×10^12
g = 3.695 m/s^2
12.) Given that the
Venus mass M = 4.87×10^24kg
Radius r = 6.05 × 10^6 m
Using the same formula for gravitational field strength g
g = GM/R2
Substitute all the parameters into the formula
g = (6.67408 × 10^-11 × 4.87×10^24)/(6.05×10^6)^2
g = 3.25×10^14/3.66×10^13
g = 8.879 m/s^2
13.) Given that the
Charge = 2.26 nC = 2.26×10^-9
Distance d = 0.05m
Electric field strength E can be calculated by using the formula below
E = Kq/d^2
Where
K = electrostatic constant 8.99 × 10^9 Nm2/C2
Substitutes all the parameters into the formula
E = (8.99 × 10^9 × 2.26×10^-9)/0.05^2
E = 20.3174/2.5×10^-3
E = 8126.96 N/C
3.If a force of 12 N is applied to an object with a mass of 2 kg, what will be its acceleration?
Answer:
6 m/s^{2}
Explanation:
The formula for force is
F = mass x acceleration
F = 12 N
mass = 2 kg
So, you can change the formula to solve for acceleration.
acceleration = F / mass
a = 12 N / 12 kg
a = 6 m/s^{2}
a car travels 60 km in 2 hours 84 km the next 1 hour and then 68 km in 8.9 hours before reaching its destination what was the cars average speed in km / h
Answer:
17.8 km/hr
Explanation:
Average speed = distance / time
The total distance traveled is 60 km + 84 km + 68 km = 212 km.
The total time is 2 hr + 1 hr + 8.9 hr = 11.9 hr.
The average speed is 212 km / 11.9 hr = 17.8 km/hr
What are two ways to increase impulse?
Answer:
increase the time the force acts or you could increase the number of temptations.

If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay:
how many protons will be left in the nucleus?
how many neutrons will be left in the nucleus?
Answer:
Protons = 28
Neutrons = 42
Explanation:
Alpha decay is one of radioactive decay in which the atomic nuclei can be illustrated by the emission or loss of helium particles of mass number 4 and proton number of 2
Because mass number is the sum of protons and neutrons, If a (hypothetical) atom with 30 protons and 44 neutrons undergoes alpha decay, 28 protons will be left in the nucleus and 42 neutrons will be left in the nucleus.
The throwback PFD is which type?
Answer:a
Explanation:
The throwback PFD is a Type III PFD. This type of PFD is designed for calm, inland water, or where there is a good chance of quick rescue. THe correct option is C.
Type III PFDs will not turn unconscious wearers to a face-up position, so the wearer may have to tilt their head back to avoid turning face down.
Type III PFDs have the same minimum buoyancy as Type II PFD. Float coats, fishing vests, and vests designed for various water sports are examples of Type III PFDs. Some Type III PFDs are designed to be inflated upon entering the water.
Offshore life jackets of Type I are suited for all areas, notably open, choppy, or isolated regions where rescue may be delayed and offer the highest buoyancy. Near-shore vests of Type II PFDs are designed for calm inland water or situations where there is a good probability of prompt rescue. Throwable PFDs of Type IV are suitable for usage in open water as well as calm, heavily used inland waters where assistance is always available. Special-purpose PFDs known as Type Vs are made for activities like kayaking and whitewater rafting.
The throwback PFD is not a Type I PFD because it does not provide the most buoyancy and is not designed for all waters. It is not a Type II PFD because it is not intended for calm, inland water or where there is a good chance of quick rescue. It is not a Type IV PFD because it is not intended for calm, inland water with heavy boat traffic, where help is always present. It is not a Type V PFD because it is not designed for specific activities such as kayaking or whitewater rafting.
Therefore, the correct option is C. type III.
