Answer:
Magnetic field patterns of two permanent magnets.
Explanation:
From the attached picture, it can be observed that iron filings has been caused to align with respect to the magnetic fields of permanent the magnets. The concentration of the filings at some definite spots shows the poles of the magnet. This forms a magnetic field pattern.
This simply illustrates the effect of magnetic fields on iron filings by placing magnets below a paper or cardboard with iron filings on the top of the paper. The magnetic field pattern would be lost if the magnets are removed.

How would radiation occur in space?
Answer:
Space radiation is made up of three kinds of radiation: particles trapped in the Earth's magnetic field; particles shot into space during solar flares (solar particle events); and galactic cosmic rays, which are high-energy protons and heavy ions from outside our solar system.

: where are you likely to find a cooling plant located in the duckwork? A. single family home B. A large apartment C. large factory D. A medium sized offices
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.
Hence, option C is correct

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?
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.
A mosquito's wings create a buzzing noise with a frequency of 1050 Hz. If you hear a mosquito buzzing with a frequency of 1034 Hz, at what velocity is the mosquito travelling with respect to you (in m/s)?
NO LINKS
Answer:
5.26 m/s
Explanation:
Given that,
The frequency of mosquito's wings, f = 1050 Hz
The observed frequency = 1034 Hz
We need to find the velocity of the mosquito travelling with respect to you. We have a formula to find it such that,
[tex]v=\dfrac{v}{\dfrac{f'}{f}}-v[/tex]
Where
v is the speed of sound
So,
[tex]v=\dfrac{340}{\dfrac{1034}{1050}}-340\\\\v=5.26\ m/s[/tex]
So, the required velocity is equal to 5.26 m/s/

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
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

If a force of 40N is applied for 0.2 sec
to change the momentum of a
volleyball, what is the impulse?
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.

Look up how much power a typical light bulb uses/produces. Then look up how much power a typical microwave uses/produces. How do these appliances compare to your physical activities?
The current drawn by a microwave is greater than the amount of current used by an electric bulb, hence the microwave consumes more power.
Energy dissipated by electrical applianceThe amount of energy dissipated by an electrical appliance is the calculated using the following formulas;

Which of the following electrical components protects your home from excessive flow of current in the electrical wires?
- resistor
- fuse
- transistor
- capacitor
Answer: the correct option is FUSE.
Explanation:
Current Electricity consists of fast moving negatively charged electrons which travels in materials that allows the flow of electrons called conductors. In the generation of Electricity for distribution, two types of currents are being generated. It's either an Alternating current ( A.C) or a Direct Current ( D.C.). An A.C. consists of electric charges that constantly changes its position and direction of flow of voltage and current while D.C. the electric charge flow in one direction. For the safety of devices of the end users of the electric current ( either A.C. or D.C) generated, a FUSE is usually used to protect the appliances from too much flow of electric current.
A fuse is therefore defined as a safety device that protects appliances( such as televisions, refrigerators, computers) from current overload or voltage fluctuations which can cause damaging effects. It is made up of thin strip or strand of metallic wire with noncombustible material. These devices are usually connected in series with the components to be protected from current overload. This is so because, when there is high or excessive current, the fuse melts and it opens the circuit and disconnects it from the power supply. Some of the types of fuse includes A.C fuse and D.C. fuse.

What is
the speed of the car?
What is it
Answer:
v = 1.63 m/s
Explanation:
Given that,
The mass of a car, m = 1500 kg
The kinetic energy of a car, K = 2004 m/s
We need to find the speed of a car. The formula for the speed of a car is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\v=\sqrt{\dfrac{2K}{m}} \\\\v=\sqrt{\dfrac{2\times 2004}{1500}} \\\\v=1.63\ m/s[/tex]
So, the speed of the car is equal to 1.63 m/s.
