explain four contributory factors of unequal access to basic resources
Answer:
Answer. The big five factors of poverty (as a social problem) include: ignorance, disease, apathy, dishonesty and dependency. These, in turn, contribute to secondary factors such as lack of markets, poor infrastructure, poorleadership, bad governance, under-employment, lack of skills, lack of capital, and others.
g A ring and solid sphere are rolling without slipping so that both have a kinetic energy of 126 J. What is the rotation kinetic energy of the ring
Answer:
63J
Explanation:
The question tells us that they both have a kinetic energy of 126 J. What we are required to get is the rotation kinetic energy of the ring
Total kinetic energy =
1/2mv² + 1/2IW²
For ring,
I = mr²
And v = Rw for pure rolling
The total kinetic energy
= 1/2mr² + 1/2mv²
= 126J
126/2
= 63J
The rotational kinetic energy of the ring is therefore 63J.
Thank you!
How does temperature effect density and the flow of convection currents?
Answer:
Convection
Explanation:
Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks.
Which factors affect the rate of deposition? Check all that apply.
color of the sediment
density of the sediment
size of the sediment
texture of the sediment
velocity of the agent of erosion
Answer:
density of the sediment, size of the sediment, and velocity of the agent of erosion.

Calculate the ideal mechanical advantage of a pair of scissors where the length of the blade is 5 cm and the length of the handle is 2.5 cm.
Answer:
m = 0.5
Explanation:
Given that,
The length of the blade of scissors = 5 cm
The length of the handle = 2.5 cm
Here, effort arm is 2.5 cm and load arm is 5 cm. The mechanical advantage is the ratio of effort arm to the load arm as follows :
[tex]m=\dfrac{2.5}{5}\\\\m=0.5[/tex]
So, the ideal mechanical advantage of a pair of scissors is 0.5.

A box is being pushed by two stellar science students, one on each side of the box. Delfino is pushing
the box with a force of 10 N to the left. Aleida is pushing the box with a force of 15 N to the right. Who is
the stronger individual and what is the net force and direction on the box.
Explanation:
It is given that,
Delfino is pushing the box with a force of 10 N to the left. Aleida is pushing the box with a force of 15 N to the right.
Aleida is exerting more force. He is the more stronger individual.
Net force is given by :
F = -10+15
F = 5 N
So, the net force is 5 N and it is in right direction.

How does cold water affect the speed of dissolving?
A. Cold water slows down dissolving
B. Cold water speeds up dissolving
C. Cold water has no effect on dissolving
D. Cold water completely stops dissolving
Answer:
Cold water slows down dissolving
Cold water slows down dissolving. Hence, option (A) is correct.
What is the relationship between the solubility and the temperature?The basic relationship between solubility and temperature is as follows: A solid will dissolve more readily at higher temperatures.
Likewise, a solid element dissolves more slowly at lower temperatures. This is all due to the solvent becoming more and more excited by the heat, making it easier for it to split or break apart entirely.
for while in gases The solubility of gases decreases more rapidly as temperature rises. A gas is more soluble in water when the temperature is lower.
Henry's law, which states that the gas becomes more soluble as the pressure above the liquid solution increases, summarizes another characteristic of gas solutes.

TrueSome rocks have pores in them, which are empty spaces. If these pores are linked then fluid can flow through the rock.However,if the pores are not linked,then no liquid can flow through the rocksWhen pores are not linked,the rock is permiable.n
The modulus of elasticity for a ceramic material having 4.7 vol% porosity is 317 GPa. (a) Calculate the modulus of elasticity (in GPa) for the nonporous material.
Answer:
The answer is below
Explanation:
a) Given that the modulus of elasticity (E) = 317 GPa, to find the modulus of elasticity (in GPa) for the nonporous material ([tex]E_o[/tex]), we use the formula:
[tex]E_0=\frac{E}{1-1.9P+0.9P^2}\\\\where\ P=4.7\%=0.047,hence:\\\\ E_0=\frac{317}{1-1.9(0.047)+0.9(0.047)^2}\\\\E_0=347.3\ GPa[/tex]
b) If the porosity P = 11.1%, then the modulus of elasticity is:
[tex]E=E_0(1-1.9P+0.9P^2)=347.3(1-1.9(0.111)+0.9(0.111)^2)=278\ GPa[/tex]

What is the density of the paint if the mass of a tin containing 5000 cm3 paint is 7 kg. If the mass of the empty tin, including the lid is 0.5 kg.
We are given:
Mass of the Paint bucket (with paint) = 7000 grams
Mass of the paint bucket (without paint) = 500 grams
Volume of Paint in the Bucket = 5000 cm³
Mass of Paint in the Bucket:
To get the mass of the paint in the bucket, we will subtract the mass of the bucket from the mass of the paint bucket (with paint)
Mass of Paint = Mass of Paint bucket (with paint) - Mass of the paint Bucket (without paint)
Mass of Paint = 7000 - 500
Mass of Paint = 6500 grams
Density of the Paint:
We know that density = Mass / Volume
Density of Paint = Mass of Paint / Volume occupied by Paint
Density of Paint = 6500/5000
Density of Paint = 1.3 grams / cm³

Harnessing tidal power would involve:_______.a) letting in-flowing and/or out-flowing tide flow through turbines in a dam.b) huge floats mechanically hooked to generators.c) electrodes in the water.d) bioluminescence of marine organisms.e) all of the above
Answer:
a) letting in-flowing and/or out-flowing tide flow through turbines in a dam.
Explanation:
Tidal power makes use of the energy from the tidal force and wave action in order to generate electricity. it is a predictable source of energy.
Tidal Barrages
The system allows tides to enter, seawater flows via the dam and is trapped into the basin when the tides subside and system’s gates close.
When the tides start to move out, the gates in the dam are opened up this consist of turbines and water begins to flow out, hitting the turbines this eventually turn to produce energy.
Power is produced when the tidal range, which is the difference between low and high tide, has to be more than 5 meters.
When are zeros significant when found in front of (to the left) of the decimal point?
Answer:
If a zero is found between important digits, it is important. Zeros are also used as (not salient) holders to the left of digits if the number is in fact a decimal. Example from www.rpi.edu: , a mass of 42 g has two significant digits. Expressed in kilograms, the mass of 0.042kg should still have two significant digits.
Explanation:
Zeros are also used as (not salient) holders to the left of digits if the number is in fact a decimal. Example from www.rpi.edu: "A mass of 42 g has two significant digits. Expressed in kilograms, the mass of 0.042kg should still have two significant digits."
