Answer:
the initial kinetic energy of the basket ball is 4.8 J
Explanation:
The computation of the initial kinetic energy of the basket ball is shown below:
As we know that
Initial kinetic energy is
[tex]= \frac{1}{2}mv^2 \\\\= \frac{1}{2}\times 0.6 \times (4m/s)^2\\\\= \frac{1}{2}\times 0.6 \times 16m/s^2\\\\= 4.8 J[/tex]
Hence, the initial kinetic energy of the basket ball is 4.8 J
The pressure due to the liquid on an object immersed in that liquid is 4500 Pa
The density of the liquid is 900 kg/m.
What is the depth of the object below the surface of the liquid ?
Answer:
The depth of the object below the surface of the liquid is 0.510 meters.
Explanation:
The hydrostatic pressure ([tex]P[/tex]), measured in pascals, experimented by the object is directly proportional to density of the fluid ([tex]\rho[/tex]), measured in kilograms per cubic meter, gravitational acceleration ([tex]g[/tex]), measured in meters per square second, and depth of the object ([tex]h[/tex]), measured in meters. That is:
[tex]P = \rho\cdot g \cdot h[/tex] (1)
If we know that [tex]P = 4500\,Pa[/tex], [tex]\rho = 900\,\frac{kg}{m^{3}}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then the depth of the object is:
[tex]h = \frac{P}{\rho\cdot g}[/tex]
[tex]h = \frac{4500\,Pa}{\left(900\,\frac{kg}{m^{3}} \right)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]
[tex]h = 0.510\,m[/tex]
The depth of the object below the surface of the liquid is 0.510 meters.
The depth of the object below the liquid's surface will be
"0.510 m".
Pressure and DensityAccording to the question,
Object immersed, P = 4500 Pa
Density of liquid, ρ = 900 kg/m³
Acceleration due to gravity, g = 9.8 m/s²
We know the relation,
→ Hydrostatic pressure (P) = ρ.g.h
or,
Depth will be:
→ h = [tex]\frac{P}{\rho .g}[/tex]
By substituting the values,
= [tex]\frac{4500}{900\times 9.8}[/tex]
= [tex]\frac{4500}{8820}[/tex]
= 0.510 m
Thus the above answer is appropriate.

According to the law of universal gravitation, any two objects are attracted to each other. The strength of the gravitational force depends on the masses of the objects and their distance from each other.
Many stars have planets around them. If there were no gravity attracting a planet to its star, the planet's motion would carry it away from the star. However, when this motion is balanced by the gravitational attraction to the star, the planet orbits the star.
Two solar systems each have a planet the same distance from the star. The planets have the same mass, but Planet A orbits a more massive star than Planet B.
Which of the following statements is true about the planets?
A.
Planet B is more attracted to its star than Planet A.
B.
Planet B will keep orbiting its star longer than Planet A.
C.
Planet A orbits its star faster than Planet B.
D.
Planet A has a longer year than Planet B.
Answer:
C. Plant A orbits its star faster than Plant B

Gases are less dense than solids because their volume is comparatively more than solids.
Which of the following shows a balanced nuclear reaction?
Answer:
No. 2
Explanation:
The balanced nuclear reaction is shown by the following: ²³⁷₉₃ Np[tex]\rightarrow[/tex]⁴ ₂He +²³³₉₅ Am nuclear fission reaction.
What are nuclear reactions?There are two types of nuclear reactions which are nuclear fusion and nuclear fission .They involve the combination and disintegration of the element's nucleus respectively.
In nuclear fission, the nucleus of the atom is bombarded with electrons of low energy which splits the nucleus in to two parts .Large amount of energy is released in the process.It is used in nuclear power reactors as it produces large amount of energy.
In nuclear fusion,on the other hand, is a reaction which occurs when two or more atoms combine to form a heavy nucleus.Large amount of energy is released in the process which is greater than that of the energy which is released in nuclear fission process.

Now consider θc, the angle at which the blue refracted ray hits the bottom surface of the diamond. If θc is larger than the critical angle θcrit, the light will not be refracted out into the air, but instead it will be totally internally reflected back into the diamond. Find θcrit.
Answer:
θ_c = 24.4º
Explanation:
To find the critical angle, let's use the law of refraction where index 1 refers to the incident medium (diamond) and index 2 refers to the medium where it is to be refracted (air)
n₁ sin θ₁ = n₂ sin θ₂
for the critical angle the ray comes out refracted parallel to the surface, therefore the angle is
θ₂ = 90
n₁ sin θ₁ = n₂
θ_c = θ₁ = sin⁻¹ [tex]\frac{n_2}{n_1}[/tex]
the index of refraction of the diamond is tabulated
n₁ = 2.419
let's calculate
θ_c = sin⁻¹ ([tex]\frac{1}{2.419}[/tex])
θ_c = 24.4º

The particles of an ice cube at 0°C (represented by the blue circles) come in contact with the particles of Juan’s hand at 37°C (represented by the orange circles). Which diagram correctly represents the temperature of the two substances and the direction of heat flow?
Answer:
its b
Explanation:
The diagram which correctly represents the temperature of the two substances and the direction of heat flow is shown below.
What is heat?Heat is also referred to as thermal energy and it can be defined as a form of energy that is transferred from one physical object to another, especially as a result of a difference in temperature.
During the process of heat conduction, heat is primarily transferred between objects with different degrees of temperature and materials that are directly in contact with each other.
In conclusion, heat is generally transferred from a hotter object (37°C represented by the orange circles) to a cooler object (0°C represented by the blue circles) as shown in the image attached below.

If an object has a velocity of 15 m/s and a momentum of 30 kg m/s, what is its mass?
Answer:
30kgm/s/15m/s=2kg
Explanation:mass=momentum/velocity
The mass of the object is 2 kg.
What is momentum?The product of a particle's mass and velocity is its momentum. Momentum is a vector quantity, meaning it has both magnitude and direction. According to Isaac Newton's second equation of motion, the force acting on a particle equals the time rate of change of momentum.
Given that:
Velocity of the object: v = 15 m/s.
Momentum of the object: p = 30 kg m/s.
Let the mass of the object = m.
From the definition of momentum; we get:
momentum = mass × velocity
30 = 15 m
m = 2 kg.
Hence, mass of it is 2 kg.

Does the mass of the objects you are charging influence the amount of electric force created in an electric field?
Explanation:
Both gravitational and electric forces decrease with the square of the distance between the objects, and both forces act along a line between them. In Coulomb's law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.

Answer:
Percentage of mass converted to energy = 99.9 %
Explanation:
By far most of the solar system's mass is in the Sun itself: somewhere between 99.8 and 99.9 percent. The rest is split between the planets and their satellites, and the comets and asteroids and the dust and gas surrounding our star. Seen from afar (on the scale of distances between stars) the presence of the solar system would not be obvious. We would simply see a normal-looking star. Perhaps we would pick up the presence of Jupiter, which makes up two thirds or so of the solar system outside of the Sun, by mass.
