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.
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.

If an object is traveling in a straight line moving East then the following is true.
A distance is equal to displacement
B distance is greater than the displacement
C distance is less than the displacement
D distance is a value and displacement is equal to 0
Answer:
A distance is equal to displacement
Explanation:
An object traveling in a straight line moving East will have its displacement value to be equal to the distance.
Displacement is the distance traveled in a specific directions.
Distance is the total length of path traveled.
The displacement of the object is the value of the distance due east.
The distance is the value of the length of path covered.

A spring is hanging from the ceiling. When a 250 gram of mass is attached to the free end, the spring elongates by 5 cm. The spring constant (in N/m) is:
Answer:
k = 49 N/m
Explanation:
Given that,
Mass, m = 250 g = 0.25 kg
When the mass is attached to the end of the spring, it elongates 5 cm or 0.05 m. We need to find the spring constant. Let it is k.
The force due to mass is balanced by its weight as follows :
mg=kx
[tex]k=\dfrac{mg}{x}\\\\k=\dfrac{0.25\times 9.8}{0.05}\\\\k=49\ N/m[/tex]
So, the spring constant of the spring is 49 N/m.

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.

which two conditions would result in the strongest electric force between charged objects
Answer:
A and B
Explanation:
The two conditions which results in the strongest electric force between charged objects are when they close together secondly, when the objects are conductors with balanced charges.
What is electric force ?Electric force is the force generated between charged bodies. There are both repulsive and attractive electric forces. Like charges exerts a force of repulson between each other. Unlike charges will exert an attractive force between each other.
According to Coulomb's law of electric forces is directly proportional to the magnitude of charges and inversely proportional to the distance between them. Thus , when the objects are closer the greater force is exerted between them.
Insulators does not allow flow of free electrons and the electric force between them is weak. Whereas, when two conductors of unlike charges exerts strong electrostatic force of attraction. Hence, option B and C are correct.

A ball is thrown vertically upwards from the ground with an initial velocity of 50m/s. What is the total time by the ball to get its maximum height? (take g=10)
A. 500s
B. 50s
C. 5s
D. 0.5s
Explanation:
initial velocity (u) = 50m/s
final velocity (v) = 0m/s
i.e the ball stops for a while at its maximum height.
g = 10m/s^2
from the 1st equation of vertical upward motion:
v = u - gt
hence t = (v + u)/t
t = (0 + 50)/10
t = 50/10 = 5s.
C. 5s.
Answer:
c
Explanation:
(a) Initial velocity of ball (u)=50m/s, acceleration of ball =−g,
final velocity at the highest point (v)=0
So applying the 3rd equation of motion we get:

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]
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.
A heavy bank-vault door is opened by the application of a force of 300 N directed perpendicular to the plane of the door at a distance of 0.80 m from the hinges. What is the torque?
Question 4 options:
1.) 120 Nm
2.) 240 Nm
3.) 375 Nm
4.) 300 Nm
Answer:
240Nm
Explanation:
Given parameters:
Force on the bank vault = 300N
Distance to the plane of the vault = 0.8m
Unknown:
Torque = ?
Solution:
Torque is the component of force that causes an object to rotate about an axis;
Torque = Fr x sinФ
Here Ф = 90°
r = distance
Torque = 300 x 0.8 x Sin 90°
Torque = 240Nm

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.

Yes, there are human health risks caused by exposure to x-rays, X-rays may cause damage to cells in the body, and large doses may lead cells to be cancerous, causing mutations in the DNA.
What are X-rays?X-rays are electromagnetic waves with minimal wavelengths and high frequencies. Their wavelengths typically range from 10⁸ to 10¹² meters, and their corresponding frequencies are typically between 10¹⁶ and 10²⁰ hertz (Hz).
Charged particles are frequently accelerated (or decelerated) to produce X-rays; examples include an electron beam striking a metal plate in an X-ray tube and an electron beam circulating in a synchrotron particle accelerator or storage ring. The energy level spacing in the atoms can also be used to determine the discrete wavelengths of X-rays that highly excited atoms can emit.
X-rays may cause damage to cells in the body, large doses may lead cells to be cancerous, causing mutations in the DNA.
