Answers
Answer:
Option C
Explanation:
In a large sized factory, it is essential to create cooling system based on duct work because it can then be able to regulate cooling of any section of the factory from one place. Also, ductwork cooling is preferred in large spaces such as big offices building, towers, factories etc.

to change the momentum of a
volleyball, what is the impulse?
Answers
Answer:
J = 8 kg-s
Explanation:
Given that,
Force, F = 40 N
Time, t = 0.2 s
We need to find the impulse. We know that,
Impulse, J = F×t
So,
J = 40 × 0.2
J = 8 kg-s
So, the impulse is 8 kg-s.

A car is traveling at 120 kilometers per hour with 35,000 joules of kinetic energy on the freeway when it suddenly applies its brakes and comes to a screeching stop. How much of the original 35,000 joules of energy is left?
Answers
Answer:
0 J is left (No amount of the original 35000 J energy is left)
Explanation:
From the question
Kinetic Energy (K.E) = 1/2mv²................... Equation 1
Where m = mass of the car, v = velocity of the car.
make m the subject of the equation.
m = 2K.E/v²..................... Equation 2
Given: K.E = 35000 Joules, v = 120 km/h = (120×3600/1000) = 432 m/s
Substitute these values into equation 2
m = (2×35000)/432²
m = 0.375 kg.
If a brake is suddenly apply,
Then, the velocity of the car = 0 m/s.
Therefore,
K.E = 1/2(0.375×0²)
K.E = 0 J.
From the baove analysis, No amount of the original 35000 J energy is left.

Objects 1 and 2 attract each other with a electrostatic force
of 36.0 units. If the distance separating Objects 1 and 2 is
changed to one-half the original value (i.e., halved), then the
new electrostatic force will be units.
Answers
Answer:
F = 144 units
Explanation:
For this exercise we use coulomb's law, for the initial conditions
F₀ = [tex]k \frac{q_1q_2}{r_o^2}[/tex]
indicate that the force F₀ = 36.0 units and the distance is reduced to r = r₀/2 which is the new force
F = [tex]k \frac{ q_1q_2 }{(r_o/2)^2}[/tex]
we substitute
F = 4 [tex]k \frac{q_1q_2}{r_o^2}[/tex]
F = 4 F₀
we calculate
F = 4 36
F = 144 units

The volume of an object as a function of time calculated by V=At^3+B/t,where t is time measured in seconds and V is in cubic meters. Determine the dimension of the constants A and B
Answers
Answer:
A = L^3 T^-3 , B = L^3 T
Explanation:
Given: volume ( V ) = At^3 + B/t ------ ( 1 )
dimension of volume = L^3
and the Dimension of time = T
back to equation ( 1 )
L^3 = A * T^3 ------- ( 2 )
also L^3 = B/T ------- ( 3 )
from equation ( 2 )
A = L^3 T^-3
from equation ( 3 )
B = L^3 T
The dimensions of the constants A and B
A = L^3 T^-3 , B = L^3 T

in each of the following divide the second number by the first number and find the quotient:3/4,-3/8
Answers
Answer:
[tex]\dfrac{-1}{2}[/tex]
Explanation:
We need to divide the second number by the first number and the numbers are 3/4,-3/8.
First number = 3/4
Second number = -3/8
Dividing the second number by the first number.
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}[/tex]
We know that,
[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\times \dfrac{d}{c}[/tex]
So,
[tex]\dfrac{\dfrac{-3}{8}}{\dfrac{3}{4}}=\dfrac{-3}{8}\times \dfrac{4}{3}\\\\=\dfrac{-1}{2}[/tex]
So, the answer is (-1/2)

A day on a distant planet observed orbiting a nearby star is 21.5 hr. Also, a year on the planet lasts 69.3 Earth days. In other words, for the purposes of unit conversion, there are 24 hr in a day, 60 min in an hour, and 60 s in a minute, as it would for astronomers on Earth observing the planet. Calculate the average angular speed of the planet about its own axis of rotation in radians per second, with the second as measured on Earth. what is the speed of rotation? Calculate the average angular speed of the planet as it travels around its neighboring star, with the second as measured on Earth. what is the speed of orbit?
Answers
Answer:
Part A
The angular speed of rotation of the plane is 8.11781 × 10⁻⁵ rad/s
Part B
The angular speed of orbit of the planet is 1.04938 × 10⁻⁶ rad/s
Explanation:
The parameters of the planet are;
The duration of a day on the distant planet = 21.5 hr.
The duration of a year on the distant planet = 69.3 Earth days
Part A
The duration of a day = The time to make one complete revolution of 2·π radians
∴ The average angular speed about its axis, [tex]\omega_{rotation}[/tex] = Angle turned/Time
∴ [tex]\omega_{rotation}[/tex] = 2·π/(21.5 × 60 × 60) s ≈ 8.11781 × 10⁻⁵ rad/s
The average angular speed of the planet about its own axis, [tex]\omega_{rotation}[/tex] = 8.11781 × 10⁻⁵ rad/s
The angular speed of rotation of the plane [tex]\omega_{rotation}[/tex] = 8.11781 × 10⁻⁵ rad/s
Part B
The time it takes the planet to revolve round the neighboring star once = 69.3 Earth days
Therefore, the average angular speed of the planet around its neighboring star, [tex]\omega _{Star}[/tex], is given as follows;
[tex]\omega _{Orbit}[/tex] = 2·π/((69.3 × 24 × 60 × 60) s) = 1.04938 × 10⁻⁶ rad/s
The average angular speed of orbit, [tex]\omega _{Orbit}[/tex] = 1.04938 × 10⁻⁶ rad/s
The angular speed of orbit of the planet, [tex]\omega _{Orbit}[/tex] = 1.04938 × 10⁻⁶ rad/s.
