Answer: ethanol which will dissolve in both water (a polar solvent) and gasoline (a non-polar solvent)
Explanation:
According to the concept of solubility, ethanol is a molecule which is soluble in both polar and non-polar solvents.
What is solubility?
Solubility is defined as the ability of a substance which is basically solute to form a solution with another substance. There is an extent to which a substance is soluble in a particular solvent. This is generally measured as the concentration of a solute present in a saturated solution.
The solubility mainly depends on the composition of solute and solvent ,its pH and presence of other dissolved substance. It is also dependent on temperature and pressure which is maintained.Concept of solubility is not valid for chemical reactions which are irreversible. The dependency of solubility on various factors is due to interactions between the particles, molecule or ions.

In which sections of the track will the sled experience an unbalanced force?
A Sections 1 and 3
B Sections 2 and 3
C Sections 2 and 4
D Sections 3 and 4
Answer:
C. 2 and 4
Explanation:
my teacher went over it and the answer was that
The sections of the track in which the sled would experience an unbalanced force are: C. Sections 2 and 4.
The two types of force.In Science, there are two (2) main types of force that acts on an object and these include:
Balanced forceUnbalanced forceWhat is an unbalanced force?An unbalanced force refers to a type of force that occurs when two (2) or more forces acting on an object are unequal in magnitude, and as such, it typically results in a change of motion.
In this scenario, the sections of the track in which the sled would experience an unbalanced force are sections 2 and 4 respectively.

Juan rides his horse with a constant
speed of 18 km/h. How far can he travel
in 1/2 hour?
Answer:
He traveled 9km
Explanation:
To do this problem you need to use the equation which is Speed= distance/time and this problem gives you the speed which is 18 km/h and it gives you the time 1/2 hour so you write the equation 18= d/ 1/2 which his distance is 9km
If the wavelength is 10 m and the frequency is 5 Hz, what is the wave speed?

An airplane went from 120 m/s to 180 m/s in 4.0 seconds. What was its acceleration?
45 m/s2
15 m/s2
60 m/s2
30 m/s2
Answer:
15 m/s^2 The first thing to calculate is the difference between the final and initial velocities. So 180 m/s - 120 m/s = 60 m/s So the plane changed velocity by a total of 60 m/s. Now divide that change in velocity by the amount of time taken to cause that change in velocity, giving 60 m/s / 4.0 s = 15.0 m/s^2 Since you only have 2 significaant figures, round the result to 2 significant figures giving 15 m/s^2

How much work is done on a small car if a 1000 N force is exerted to move it 75
Answer:
75000J
Explanation:
Given parameters:
Force applied on the car = 1000N
Distance moved = 75m
Unknown:
Work done = ?
Solution:
The work done by a body is the force applied to move it through a particular distance.
So;
Work done = Force x distance
Therefore;
Work done = 1000 x 75 = 75000J

How much power does an Ox pulling a plow 20 m cross a field, exerting 120J of work over a period of 15 s?
Answer:
8W
Explanation:
Given parameters:
Distance covered = 20m
Work done = 120J
Time = 15s
Unknown:
How much power does the Ox exerts = ?
Solution:
Power is the rate at which work is being done
Power = [tex]\frac{Work done }{time}[/tex]
Power exerted by ox = [tex]\frac{120}{15}[/tex] = 8W

How does the magnitude of the force depend on the magnitude (absolute value) of charge 1 and charge 2.
Answer:
Product
Explanation:
The force between two charges is given by :
[tex]F=\dfrac{kq_1q_2}{r^2}[/tex] ...(1)
Where
k is electrostatic constant
q₁ and q₂ are charges
r is the distance between charges
From equation (1), it is clear that the magnitude of the force is directly proportional to the product of charges.
The potential energy of a watermelon is 15.0 J. The watermelon is 3.0 m high. What is the mass of the watermelon?
g = 9.8 m/s2
Answer:
m = 0.51[kg]
Explanation:
Potential energy is defined as the product of mass by gravity by height.
[tex]E_{pot}=m*g*h[/tex]
where:
Epot = potential energy = 15 [J]
m = mass [kg]
g = gravity acceleration = 9.8 [m/s²]
h = elevation = 3 [m]
Now replacing:
[tex]E_{pot}=m*g*h\\15=m*9.8*3\\m = 0.51[kg][/tex]

A worker does 196 J of work to lift a bag 2m. What is the mass of the bag?
Work = 196 J = 196 kg.m^2.s^-2
[We know that 1J = 1 kg.m^2.s^-2]
Displacement = 2m
Acceleration (g) = 9.8ms^-2
We know that,
W=Fs and F=ma
So, W = (ma)s
=> W = m×a×s
=> 196 kg.m^2.s^-2 = m×9.8ms^-2×2m
=> 196 kg.m^2.s^-2 = m×19.6m^2.s^-2
=> 196 kg.m^2.s^-2 = m×19.6m^2.s^-2
=> (196 kg.m^2.s^-2)/(19.6m^2.s^-2) = m
=> 10kg = m
So, mass = 10kg

Answer:
[tex]\boxed {\boxed {\sf 15 \ kg*m/s}}[/tex]
Explanation:
Momentum is the product of mass and velocity.
[tex]p=m*v[/tex]
The mass of the ball is 1.5 kilograms and the velocity is 10 meters per second.
[tex]m= 1.5 \ kg \\v= 10 \ m/s[/tex]
Substitute the values into the formula.
[tex]p= 1.5 \ kg* 10 \ m/s[/tex]

[tex]p=15 \ kg*m/s[/tex]
The momentum of the ball is 15 kilogram meters per second.
Answer:
15 kg m/s
Explanation:
[tex]p = mv \: = 1.5 \times 10 = 15 \: kgm {s}^{ - 1} [/tex]
