The final speed of an airplane is v = 92.95 m/s
The rate of change of position of an object in any direction is known as speed i.e. in other word, Speed is measured as the ratio of distance to the time in which the distance was covered.
Solution-
Here given,
Acceleration a= 10.8 m/s2 .
Displacement (s)= 400m
Then to find final speed of airplane v=?
Therefore from equation of motion can be written as,
v²=u²+ 2as
where, u is initial speed, v is final speed ,a is acceleration and s is displacement of the airplane. Therefore by putting the value of a & s in above equation and (u =0) i.e. the initial speed of airplane is zero.
v²= 2×10.8 m/s²×400m
v²=8640m/s
v=92.95m/s
hence the final speed of airplane v =92.95m/s

The Mole fraction of Water in this solution is 0.34
We know that,
Mole Fraction of Water = No. of moles of Water / Total number of moles of the solution
No. of moles = Mass / Molar mass
Given that,
Mass of Water = 11g
Mass of Acetic acid = 72g
Molar mass of Water = 18.015 g/mol
Molar mass of Acetic acid = 60.052 g/mol
No. of moles of Water= 11 / 18.015= 0.611 moles
No. of moles of Acetic acid = 72 / 60.052= 1.199 moles
Total no. of moles = 0.611+ 1.199 = 1.81 moles
Mole fraction of chloroform = 0.611 / 1.81 = 0.338

What is States of Matter?The state of the substance is one of the characteristic forms that the many phases of the matter take. The four states of matter that can be encountered in daily life are solid, liquid, gas, and plasma. It is believed that many other states can only be found in extremely cold or dense matter, including the Bose-Einstein condensate and neutron degenerate matter. Quark-gluon plasmas are among the other conceivable states that are currently thought to be hypothetical.
The states that can exist inside the gadget are gaseous, liquid, or solid. A solid can be identified by its hard form, strong atomic bonds, and high viscosity. Insofar as they have a three-dimensional periodic atomic structure, most solids are crystalline; nevertheless, some solids (like glass) lack this periodic arrangement and are non-crystalline or amorphous instead.
According to the question,
The solid is densely packed with particles. The forces between the particles are so strong that they are only able to vibrate and not move freely. The solid as a result has a steady, distinct shape as well as a specific volume.
A liquid is a nearly incompressible fluid with a constant volume regardless of the pressure that adapts to the shape of its container. If both temperature and pressure are constant, volume is defined. When a solid is heated over its melting point, it turns liquid because the pressure exceeds the material's triple point.

Which method can be used to calculate the displacement of the badger?The points on the graph are;
(0, 0), (1, 5), (3, -5), (6, -5)
The point t = 2 is between (1, 5) and (3, -5)
The slope, m, of the line containing the point t = 2 is therefore;
m = (-5 - 5)/(3 - 1) = -5The equation of the line is therefore;
v - 5 = -5•(t - 1)
v = -5•t + 5 + 5 = -5•t + 10
v = -5•t + 10
At t = 2, we have;
v = -5×2 + 10 = 0
The velocity at t = 2 is 0 m/s
The value of the acceleration is the same as the slope, m = a = -5
Given that the initial velocity at t = 2 is 0, we have;
∆x = u•t + 0.5•a•t²
At t = 3, the time of travel from the time t = 2 is 1 seconds, which gives;
∆x = 0×5 + 0.5×(-5)×1² = -2.5

What depth of oil, specific gravity of 0.750, will produce a pressure of 46 psig?
The depth of oil is 43 m
We know that
P = ρ g h
where,
P = Pressure of fluid
ρ = Density of fluid
g = Acceleration due to gravity
h = Depth of fluid
Given that,
P = 46 psig = 3.2 * [tex]10^{5}[/tex] N / [tex]m^{2}[/tex]
s = 0.75
ρ = 0.75 * 1000 = 750 kg / [tex]m^{3}[/tex]
g = 9.81 m / [tex]s^{2}[/tex]
Here we round the value of g = 10 m / [tex]s^{2}[/tex]
h = P / ρ g
h = ( 3.2 * [tex]10^{5}[/tex] ) / ( 750 * 10 ) = 42.67 m
h = 43 m
Fluid pressure is the measurement of force per unit area that acts on an object in the fluid.
Therefore, the depth of oil is 43 m

An object moving along the x axis experiences an acceleration of 7.0 m/s2. this means the object is:_________
This means the object is increasing its velocity by 7.0 m/s in every second.
What is acceleration?Acceleration: the rate at which the speed and direction of a moving object vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates. Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.
The meter per second per second (m/s2) unit of acceleration. The square meter is a measure of area (m2). The equation a = v/t denotes acceleration (a), which is the change in velocity (v) over the change in time (t).
This enables you to calculate the change in velocity in meters per second squared (m/s2). Since acceleration is a vector quantity, both its magnitude and its direction are included.
