A cube has height of 3cm. What is the volume of the cube?
Answer:
27[tex]cm^{3}[/tex]
Explanation:
The formula to find the volume of a cube is Volume=height cubed(or to the power of 3) so you would replace height with 3cm and get the equation Volume= 3 to the power of 3. So 3 x 3 x 3 = 27. So your answer would be:
27[tex]cm^{3}[/tex]

Sarah is demolishing two clock towers, one on either side of the city. She sets up the explosives to go off at the same time when she sends the signal from the center of the city. She sends the signal and sees both clock towers blow up at the same time and sees both towers show 1pm exactly. Adam is flying past the earth traveling at a speed close to the speed of light as sees the building farthest away from him blow up first. Explain how Sarah can see them blow up at the same time, but Adam sees them blow up at different times.
Answer:
According to Lorentz transformation, the time observed of by objects moving in different reference frames are related to their velocity of motion and the speed of light
The time measured by Sarah who is located at the source of the signal and the center of the explosion is different from the time measured by Adam who is moving relative to Sarah and observes the signals moving at different speeds and therefore observes the buildings blow up not immediately but at different times
Explanation:
The time and space dilation equations are given as follows;
[tex]\Delta t = \dfrac{\Delta t'}{\sqrt{1 - \dfrac{v^2}{c^2} } }[/tex]
[tex]L = L' \times \sqrt{1 - \dfrac{v^2}{c^2} }[/tex]
Where;
Δt' = The time measured by Adam
Δt = The time measured by Sarah
L' = The distance measured by Adam
L= The distance measured by Sarah
v = The velocity at which Adam is moving
Let 'u' represent the speed of the signals
Given that Adam is traveling in between the two clock towers such that one signal is moving in the opposite direction towards him while the other signal moves in the his direction, by relativistic velocity addition, we have;
The velocity with which Adam observes the signal coming towards him, v' is given as follows;
v'' = (v + u)/(1 + v·u/c²)
∴ v'' > v
For the signal moving in the direction of Adam, we have;
v''' = (v - u)/(1 - v·u/c²)
v''' < v
Therefore, we have;
The time it takes the light to reach Adam from the furthest Tower which he passes as he is flies past Sarah in the middle, Δt'' is given as follows;
[tex]\Delta t'' = {\Delta t'} \times {\sqrt{1 - \dfrac{v''^2}{c^2} } }[/tex]
For the closer tower which Adam approaches, we have;
[tex]\Delta t''' = {\Delta t'} \times {\sqrt{1 - \dfrac{v'''^2}{c^2} } }[/tex]
Given that v'' > v''', therefore Δt'' < Δt''' and the time the light from the furthest building is seen first by Adam before the light from the closer building.

Item 3 A manufacturer makes lightbulbs and claims that their reliability is 98 percent. Reliability is defined to be the proportion of nondefective items that are produced over the long term. If the company's claim is correct, what is the expected number of nondefective lightbulbs in a random sample of 1,000 bulbs?
Answer:
980 is the expected number of nondefective lightbulbs in a random sampling of 1,000 bulbs
Explanation:
If the company claims is right, this is the task that should be done
Lightbulbs = 1,000 * 0.98 = 980
Therefore, 980 working bulbs is expected out of a sample of 1,000 lightbulbs
A tourist follows a passage that takes her 160 m west, then 180.m at an angle of 45.0∘ south of east, and finally 250 m at an angle 35.0∘ north of east. The total journey takes 12 minutes. (4)
a. Calculate the magnitude of her displacement from her original position.
b. She measures the distance she has walked to a precision of 5%. She times her total journey to ±20 s. (4)
(i) What is her average speed?
(ii) What is the absolute uncertainty on her absolute speed?
Answer:
a) R = 172.82 m, 5.3 north of east b) v = (0.24 ± 0.01) m / s
Explanation:
a) the displacement is a vector, so the easiest method to lock is looking for each component
let's start decomposing the vectors
x₁ = - 160 m
second shift
angle 45 south of east
cos (-45) = x₂ / d₂
sin (-45) = y₂ / d₂
x₂ = d₂ cos 45
y₂ = -d₂ sin 45
x₂ = 180 cos 45 = 127.28 m
y₂ = -180 sin 45 = - 127.28 m
third shift
cos 35 = x₃ / d₃
sin 35 = y₃ / d₃
x₃ = d₃ cos 35
y₃ = d₃ sin 35
x₃ = 250 cos 35 = 204.79 m
y₃ = 250 sin 35 = 143.39 m ₃
X axis
x_total = x₁ + x₂ + x₃
x_total = -160 +127.28 +204.79
x_total = 172.07 m
Y axis
y_total = y₁ + y₂ + y₃
y_total = 0 - 127.28 + 143.39
y_total = 16.11 m
to compose the displacement we use the Pythagorean theorem
R = [tex]\sqrt{x^2 +y^2}[/tex]
R = [tex]\sqrt{172.07^2 + 16.11^2 }[/tex]
R = 172.82 m
in angle is
tan θ = y_total / x_total
ten θ = 16.11 / 172.07 = 0.0936
θ = tan⁻¹ 0.0936
θ = 5.3
angle is 5.3 north of east
b) the error in the distance is 5%,
e% = ΔR/R 100
ΔR = e% R / 100
ΔR = 5 172.82 / 100
ΔR = 8.6 m
the time error Dt = 20 s
We calculate the speed and this we calculate the error
v = R / t
v = 172.82 / 12 60
v = 0.240027 m / s
the error in this magnitude is
Δv = [tex]\frac{dv}{dR} \ \Delta R + \frac{dv}{dt} \ \Delta t[/tex]
Δv = [tex]\frac{1}{t} \ \Delta R + \frac{R}{t^2 } \ \Delta t[/tex]
Δv = [tex]\frac{ 8.6}{720} + \frac{172.82 \ 20}{720^2 }[/tex]
Δv = 0.013 m / s
the measurement result is
v = (0.24 ± 0.01) m / s

Question 19 of 30
A helium balloon's temperature is raised by 1°C. Will this cause its molecules to move faster or slower?
they will move at the same speed
faster
slower
heating of anything increases the kinetic energy of its molecules, so the molecules will move faster.
A helium balloon's temperature is raised by 1°C. This will cause molecules to move faster.
What is the temperature?The temperature has an impact on this average kinetic (motional) energy. Their average kinetic energy likewise rises when gas molecules warm up.
As a result, they travel more quickly and collide more frequently and violently inside the balloon. The temperature has an impact on the hot air balloon's internal pressure. The molecules move more quickly and forcefully against the interior wall of the balloon as they warm up.
A region of the balloon is subjected to more force due to the gas particles' greater velocity, which raises the pressure there.
Therefore, the temperature of a helium balloon is increased by 1°C. Molecules will move more quickly as a result.

Which describes time dilation?
The faster an object moves, the more stretched time becomes.
The more slowly an object moves, the more stretched time becomes.
The faster an object moves, the more time it takes for light to travel a given distan
O The faster an object moves, the less time it takes for light to travel a given distanc
Answer:
A). The faster an object moves, the more stretched time becomes.
Explanation:
'Time dilation' is described as the 'slowing of the passage of time experienced by objects in motion relative to an observer that is measurable only at the relative speeds.' As per this particular relativity theory, the observer witnesses an elongated time with reference to the other setting. This reduction in speed of time(slowing down) becomes more clear and evident in the case of an object moving briskly near to the light's speed. Thus, option A is the correct answer.

A tank has the shape of an inverted circular cone with height 16m and base radius 3m. The tank is filled with water to a height of 9m. Find the work required to empty the tank by pumping all of the water over the top of the tank. Use the fact that acceleration due to gravity is 9.8 m/sec2 and the density of water is 1000kg/m3. Round your answer to the nearest kilojoule.
Answer:
[tex]W=17085KJ[/tex]
Explanation:
From the question we are told that:
Height [tex]H=16m[/tex]
Radius [tex]R=3[/tex]
Height of water [tex]H_w=9m[/tex]
Gravity [tex]g=9.8m/s[/tex]
Density of water [tex]\rho=1000kg/m^3[/tex]
Generally the equation for Volume of water is mathematically given by
[tex]dv=\pi*r^2dy[/tex]
[tex]dv=\frac{\piR^2}{H^2}(H-y)^2dy[/tex]
Where
y is a random height taken to define dv
Generally the equation for Work done to pump water is mathematically given by
[tex]dw=(pdv)g (H-y)[/tex]
Substituting dv
[tex]dw=(p(=\frac{\piR^2}{H^2}(H-y)^2dy))g (H-y)[/tex]
[tex]dw=\frac{\rho*g*R^2}{H^2}(H-y)^3dy[/tex]
Therefore
[tex]W=\int dw[/tex]
[tex]W=\int(\frac{\rho*g*R^2}{H^2}(H-y)^3)dy[/tex]
[tex]W=\rho*g*R^2}{H^2}\int((H-y)^3)dy)[/tex]
[tex]W=\frac{1000*9.8*3.142*3^2}{9^2}[((9-y)^3)}^9_0[/tex]
[tex]W=3420.84*0.25[2401-65536][/tex]
