Work
In physics work is said to be done when a force acting on a body displaces it through a certain distance. The work by a constant force is measured by the dot product of force will displacement.
i.e. W = F.S or W = F S cosq …(1)
where F = force and S = displacement
And q = angle between F and S.

Which of Newton’s laws of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and the same direction unless acted upon by an unbalanced force?(1 point)
According to Newton's First Law of Motion, a body at rest will continue to be at rest unless another force acts on it, and a body moving at a constant speed will continue to move in a straight path unless another force acts on it.
what is the Newton’s laws of Inertia?A body must be subject to an external force in order to accelerate (or decelerate) or alter its direction of motion. Net forces or imbalanced forces are other names for external forces.
Inertia is the quality that a body possesses that prevents it from moving when at rest or from speeding up or slowing down while in motion. The mass, or quantity of substance in a body, directly relates to inertia. A body has more inertia the more mass it possesses.
what is Second Law of Motion ?According to the Second Law of Motion, if an imbalanced force applies on a body, the body will accelerate (or decelerate), changing its speed. It is possible to state that a body at rest is thought to have zero speed ( a constant speed). Therefore, an imbalanced force is any force that causes a body to move. Additionally, an imbalanced force is any force that causes a body to move slowly or quickly, such as gravity or friction. The formula below can be used to demonstrate this law.
F= ma
The imbalanced force is F.
The object's mass is m.
The force's acceleration, a, is measured.

an object has a mass of 14 grams and a density of 7 g/mL. When placed in water it sinks. What is the Volume of water displaced?
A 28g
B 14ml
C 98ml
D 2ml
Explanation:
D = M/V
We rearrange this equation to get V = M/D
So 14 g/7 g/mL,
the grams cancel out, and we're left with 2 mL.
D is the answer.
The volume of water displaced by the body is 2 ml.
What is volume of a body?Volume of a body is amount of space occupied by a body. As it has only magnitude (no direction), it is a scalar quantity. SI unit of volume is [tex]m^{3}[/tex].
Now, it is given that,
Mass of the object is 14 grams.
Density of the object is 7 g/ml.
So, volume of the object will be = (mass of the object)/(density of the object)
= 14 grams/(7 g/ml).
= 2 ml.
When the object is placed in water, it sinks. That's why, volume of water displaced by it is equal to the total volume of the body.
Hence, The volume of displaced water is 2 ml.

In a scientific test conducted in Arizona, a special cannon called HARP (High Altitude Research Project) shot a projectile straight up to an alti-tude of 180.0 km. If the projectile's initial speed was 3.00 km/s, how long did it take the projectile to reach its maximum height?
Answer:
It took the projectile 120 s to reach the maximum height.
Explanation:
Given;
maximum height of the projectile, s = 180 km = 180,000 m
initial speed of the projectile, u = 3 km/s = 3000 m/s
final velocity at maximum height, v = 0
Apply the following kinematic equation for average velocity of the projectile;
[tex]s = (\frac{v+u}{2} )t\\\\(v+u)t = 2s\\\\t = \frac{2s}{v+u} \\\\t = \frac{2*180,000}{0+3,000}\\\\ t = 120 \ s[/tex]
Therefore, it took the projectile 120 s to reach the maximum height.

Why do we use scatter plots for most data in Physical Science? Question 1 options: because the teacher said to use scatter plots because scatter plots show 100% of the data like a pie because scatter plots show the relationship between the independent and dependent variables because scatter plots show data for categories that do not overlap
Answer:
scatter plots show the relationship between the independent and dependent variables
Explanation:
A scatter plot is a graph which shows two variables plotted along two axes (usually the x and y axes). Scatter plots are useful in establishing any form of correlation between the dependent and independent variables in any study.
Correlation simply means the degree of relationship between variables, that is, how much does one variable affect the other? When scatter plots are almost a straight line graph, there is a high correlation between the variables. When the points in a scatter plot are isolated, there is little (sometimes zero) correlation between the variables.
Without completing the calculations, determine what the new volume will be in the problem below. Also, explain how you were able to determine the new volume without completing the calculations. Pay special attention to how the pressure is changing. An 80.0-mL sample of carbon monoxide gas (CO) is stored at a pressure of x kPa. The pressure is doubled to 2x kPa. What is the new volume?
According to the Boyle's law, as pressure is inversely proportional to volume at constant temperature the the new volume of gas is 40 ml.
What is Boyle's law?Boyle's law is an experimental gas law which describes how the pressure of the gas decreases as the volume increases. It's statement can be stated as, the absolute pressure which is exerted by a given mass of an ideal gas is inversely proportional to its volume provided temperature and amount of gas remains unchanged.
Mathematically, it can be stated as,
P∝1/V or PV=K. The equation states that the product of of pressure and volume is constant for a given mass of gas and the equation holds true as long as temperature is maintained constant.The nature of graph obtained when gas obeys Boyle's law is hyperbolic curve.

The volume of a cube is equal to the product of height by width by length, all these dimensions are equal.
V = L*L*L
where:
L = 5 [cm]
V = (5)^3
V = 125 [cm^3]
Density is defined as the relationship between mass and volume.

What keeps the sun shining
Answer:
The Sun shines by turning hydrogen into helium in its core.
Explanation:
This process is called nuclear fusion. Fusion happens when lighter elements are forced together to become heavier elements. When this happens, a tremendous amount of energy is created.
Compute for the total mechanical energy of a 3.5 kg baseball dropped from a height of 3 meters moving at a speed of 10 m/s. NEED ASAP GRADE 8 SCIENCE TY IN ADVANCE :))
Mechanical energy = Kinetic Energy + Potential Energy
Kinetic Energy :Kinetic energy = 1/2 * m * v² = 1/2 * 3.5 * (10)²
=> Kinetic energy = 175 J
Potential Energy :Potential energy = m * g * h = 3.5 * 10 * 3 = 105 J
Hence,
Mechanical energy = Kinetic Energy + Potential Energy
= 175 J + 105 J
= 280 J
Taking into account the potencial, kinetic and mechanical energy, the total mechanical energy is 278.005 J.
Potencial energyPotential energy refers to the position that a mass occupies in space and its magnitude is directly proportional to the height at which the object is, with respect to a reference position, to the mass of the object and to gravity:
Ep = m×g×h
Kinetic energyOn the other hand, kinetic energy manifests itself when bodies move and is associated with speed. The kinetic energy of a body depends on its mass and the square of its speed:
Ec = [tex]\frac{1}{2}[/tex]×m×v²
Mechanical energyThe mechanical energy of a body is the capacity it has to carry out mechanical work, that is, to produce a movement due to causes of mechanical origin, such as its position or its speed.
The mechanical energy of a body is the sum of its kinetic energy and its potential energy:
Em = Ep + Ec
Where
Em is the mechanical energy (J).Ep the potential energy (J). Ec the kinetic energy (J).Then:
Em= m×g×h + [tex]\frac{1}{2}[/tex]×m×v²
Principle of conservation of mechanical energyThe Principle of conservation of mechanical energy indicates that, in the absence of friction and without the intervention of any external work, the sum of the kinetic and potential energies remains constant, that is, the mechanical energy of a body remains constant throughout the movement. if no friction force acts.
This caseIn this case, you know that:
m= 3.5 kgg= 9.81 [tex]\frac{m}{s^{2} }[/tex]h= 3 mv= 10 [tex]\frac{m}{s}[/tex]Complying with the Principle of Conservation of Mechanical Energy and replacing in the expression of mechanical energy:
Em= 3.5 kg×9.81 [tex]\frac{m}{s^{2} }[/tex]×3 m + [tex]\frac{1}{2}[/tex]×3.5 kg×(10 [tex]\frac{m}{s}[/tex])²
Solving:
Em=103.005 J + 175 J
Em= 278.005 J
