1. What is the kinetic energy of a 1.75 kg ball travelling at a speed of 54 m/s?
Answer:
We conclude that the kinetic energy of a 1.75 kg ball traveling at a speed of 54 m/s is 2551.5 J.
Explanation:
Given
Mass m = 1.75 kgVelocity v = 54 m/sTo determine
Kinetic Energy (K.E) = ?
We know that a body can possess energy due to its movement — Kinetic Energy.
Kinetic Energy (K.E) can be determined using the formula
[tex]K.E=\frac{1}{2}mv^2[/tex]
where
m is the mass (kg)v is the velocity (m/s)K.E is the Kinetic Energy (J)now substituting m = 1.75, and v = 54 in the formula
[tex]K.E=\frac{1}{2}mv^2[/tex]
[tex]K.E=\frac{1}{2}\left(1.75\right)\left(54\right)^2[/tex]
[tex]K.E=1458\times 1.75[/tex]
[tex]K.E=2551.5[/tex] J
Therefore, the kinetic energy of a 1.75 kg ball traveling at a speed of 54 m/s is 2551.5 J.
The wet density of a gravel was found to be 2.32 Mg/m^3 and the field water content was 16%. In the laboratory, the density of the solids was found to be 2.70 Mg/m^3, and the maximum and minimum void ratios were 0.59 and 0.28, respectively. Calculate the relative density (Dr) of the gravel in the field.
Answer:
the relative density of the gravel in the field is 0.7365 or 73.65%
Explanation:
Given that;
wet density of gravel [tex]r_{b}[/tex] = 2.3 Mg/m³
field water content w = 16%
density of solids in lab [tex]r_{s}[/tex] = 2.70 Mg/m³
Maximum void ratio [tex]e_{max}[/tex] = 0.59
Minimum void ratio [tex]e_{mini}[/tex] = 0.28
first we determine the dry density of gravel [tex]r_{d}[/tex] = [tex]r_{b}[/tex] / 1+ w
[tex]r_{d}[/tex] = 2.3 Mg/m³ / 1 + 0.16 = 2.3/1.16 = 1.9827 Mg/m³
we know that; [tex]r_{w}[/tex] = 1000 kg/m³ = 1 g/cm³
Specific Gravity of soil G = [tex]r_{s}[/tex] / [tex]r_{w}[/tex] = 2.70 Mg/m³ / 1 = 2.70 Mg/m³
eo = ((G×[tex]r_{w}[/tex])/[tex]r_{d}[/tex]) - 1
eo = (( 2.70 × 1) / 1.9827 ) - 1
eo = 1.3617 - 1
Co = 0.3617
so Relative density [tex]I_{D}[/tex] will be;
[tex]I_{D}[/tex] = [tex]e_{max}[/tex] - eo / [tex]e_{max}[/tex] - [tex]e_{mini}[/tex]
we substitute
[tex]I_{D}[/tex] = 0.59 - 0.3617 / 0.59 - 0.28
[tex]I_{D}[/tex] = 0.2283 / 0.31
[tex]I_{D}[/tex] = 0.7365 or 73.65%
Therefore; the relative density of the gravel in the field is 0.7365 or 73.65%

Mercury is a liquid metal having a density of 13.6 g/mL. What is the
volume of 0.45 kg of mercury metal?
Answer:
[tex]\boxed {\boxed {\sf v \approx 33.088 \ mL}}[/tex]
Explanation:
The formula for density is:
[tex]d= \frac{m}{v}[/tex]
where m is the mass and v is the volume.
The mass is 0.45 kilograms and the density is 13.6 grams per milliliter. The density is given in grams, so we must convert the mass.
There are 1000 grams in 1 kilogram or [tex]\frac{1000 \ g} {1 \ kg}[/tex]. We can multiply the mass by this ratio.
[tex]0.45 \ kg * \frac{1000 \ g} {1 \ kg} = 0.45 * 1000 \ g = 450 \ g[/tex]
Now we have values for the mass and density:
[tex]13.6 \ g/mL =\frac{450 \ g}{ v}[/tex]
Cross multiply.
[tex]\frac {13.6 \ g/mL}{1} =\frac{450 \ g}{ v}[/tex]
[tex]13.6 \ g/mL * v=450 \ g * 1 \\13.6 \ g/mL * v=450 \ g[/tex]
We are trying to find the volume, so we must isolate that variable.
13.6 and v are being multiplied. The inverse of multiplication is division. Divide both sides by 13.6
[tex]\frac {13.6 \ g/mL*v } { 13.6 \ g/mL} = \frac{ 450 \ g} {13.6 \ g/mL}[/tex]
[tex]v= \frac{ 450 \ g} {13.6 \ g/mL}[/tex]
The grams will cancel.
[tex]v= 33.0882353 \ mL\\v \approx 33.088 \ mL[/tex]
The volume is about 33.088 milliliters.

Answer:
Hertzsprung-Russell Diagram
The Hertzsprung-Russell diagram (HR diagram) is one of the most important tools in the study of stellar evolution. Developed independently in the early 1900s by Ejnar Hertzsprung and Henry Norris Russell, it plots the temperature of stars against their luminosity (the theoretical HR diagram), or the colour of stars (or spectral type) against their absolute magnitude (the observational HR diagram, also known as a colour-magnitude diagram).
Depending on its initial mass, every star goes through specific evolutionary stages dictated by its internal structure and how it produces energy. Each of these stages corresponds to a change in the temperature and luminosity of the star, which can be seen to move to different regions on the HR diagram as it evolves. This reveals the true power of the HR diagram – astronomers can know a star’s internal structure and evolutionary stage simply by determining its position in the diagram.
Explanation:
Hence the answer is C : Super Giants

11. A bowling ball has a mass of 7 kg and a velocity of 3 m/s.
(A) What is the ball's momentum?
Answer: 21 kg x m/s
Momentum can be found using the equation p = mv, or momentum = mass times velocity.
Therefore, to find the momentum of the bowling bowl, you can plug the mass and velocity values into the equation to get p = (7kg)(3m/s)
Solve the equation to get a momentum of 21kg x m/s

A person walking with a stroller at a rate of 1.5 m/s accelerates at a rate of 0.275 m/s2.
What is the velocity (in m/s) of the stroller after is has traveled 6.45 m?
Answer:
2.41m/s
Explanation:
Given parameters:
Initial velocity = 1.5m/s
Acceleration = 0.275m/s²
Distance = 6.45m
Unknown:
Final velocity = ?
Solution:
To solve this problem, we apply the kinematics equation below:
v² = u² + 2aS
v is the final velocity
u is the initial velocity
a is the acceleration
S is the distance
v² = 1.5² + (2 x 0.275 x 6.45)
v = 2.41m/s

What is the spring coefficient of a spring that stores 4000 joules of energy
when it is stretched .6 meters? *
Answer:
222.2N/m
Explanation:
Given parameters:
Elastic potential energy = 4000J
Extension = 6m
Unknown:
Spring coefficient = ?
Solution:
The elastic potential energy is the energy stored within a string.
It is expressed as;
EPE = [tex]\frac{1}{2}[/tex] k e²
k is the spring constant
e is the extension
4000 = [tex]\frac{1}{2}[/tex] x k x 6²
8000 = 36k
k = 222.2N/m

What is the guage pressure of an object with a mass of 30 kg and 5ft height?
Answer: D=pg
Explanation:
?????
15 mm Hg is the guage pressure of an object with a mass of 30 kg and 5ft height.
What is gauge pressure?The measurement of pressure in relation to atmospheric pressure is known as gauge pressure. The zero point for this pressure measurement is set at 1 atm. With relation to atmospheric pressure, pressure is measured.
When a car climbs a mountain, the gauge pressure rises as the air pressure falls, but the tire's absolute pressure stays the same, assuming no tire leaks.
guage pressure = mass×height
= 30×5
=15 mm Hg
Therefore, 15 mm Hg is the guage pressure of an object with a mass of 30 kg and 5ft height.
