Answer : At half distance between the center of the Magnetic field the magnetic pole the effect of the magnetic field generated will be half as strong
Explanation:
Magnetic force ∝ 1 / d^2
This simply means increase in the squared distance of an object leads to the decrease in the effect of the magnetic field generated by a current carrying wire.
Hence ;
At half distance between the center of the Magnetic field the magnetic pole, the effect of the magnetic field generated will be half as strong
Half the distance from a current-carrying wire to the body required to stand, in order for the magnetic field generated by the wire to be half as strong.
What is magnetic field?The magnetic field is the field in the space and around the magnet in which the magnetic field can be fill.
The value of magnetic field is reduced from a wire, with the distance of the wire.
The magnetic field is inversely proportional to the square of the distance of the current-carrying wire.
Hence, half the distance from a current-carrying wire to the body required to stand, in order for the magnetic field generated by the wire to be half as strong.

What physical quantity do you obtain when you divide
molar mass (Mm) by molar volume (Vm)?
Answer:
The mass density (ρ)
Explanation:
The molar volume (Vm) is the volume that a mole of an element or compound occupies at standard temperature and pressure STP
The molar volume can be found as follows;
[tex]Vm = \dfrac{Mm}{\rho}[/tex]
Where;
Mm = The molar mass
ρ = The mass density
The molar mass (Mm) of an element or a compound is the ratio of the mass of the element or compound to the amount of the element or compound in the given mass
The mass density, ρ, of an element or a compound is the mass of a unit volume of the element or compound
Therefore, we have;
[tex]\rho = \dfrac{Mm}{Vm}[/tex]
When we divide the molar mass (Mm) by the by the molar volume (Vm), we obtain the mass density (ρ).

The process of converting energy produced by wind turbines into electricity is about 40 percent efficient. If the transport of electricity is 90 percent efficient and fluorescent light bulb efficiency is known to be 20 percent, what is the overall efficiency for converting wind into fluorescent lighting
Answer: 7.2%
Explanation:
Given
Efficiency of converting energy produced by wind into electricity is about [tex]\eta_1=40\%[/tex]
Transport of electricity efficiency [tex]\eta_2=90\%[/tex]
Fluorescent light bulb efficiency is [tex]\eta_3=20\%[/tex]
Overall efficiency is the product of all the efficiencies i.e.
[tex]\Rightarrow \eta=\eta_1\times \eta_2\times \eta_3\\\\\Rightarrow \eta=0.4\times 0.9\times 0.2\\\Rightarrow \eta=0.072\ \text{or}\ 7.2\%[/tex]

4. A car accelerates at 2.5 m/s^2, covers 4 km in 0.8 min. How fast was it moving at the beginning
of the time interval? *
Answer:
Initial velocity, u = 23.33 m/s
Explanation:
Given the following data;
Acceleration = 2.5 m/s²
Distance = 4 km to meters = 4000 meters
Time = 0.8 mins to seconds = 0.8 * 60 = 48 seconds.
To find the initial velocity, we would use the second equation of motion;
[tex] S = ut + \frac {1}{2}at^{2}[/tex]
Where;
S represents the displacement or height measured in meters.
u represents the initial velocity measured in meters per seconds.
t represents the time measured in seconds.
a represents acceleration measured in meters per seconds square.
Substituting into the equation, we have;
4000 = u*48 + ½*2.5*48²
4000 = 48u + 1.25*2304
4000 = 48u + 2880
48u = 4000 - 2880
48u = 1120
Initial velocity, u = 1120/48
Initial velocity, u = 23.33 m/s
The circular motion of water molecules extends to a depth that is equal to:a. wave height/wavelength.b. wave height/wave period.c. wavelength/wave height.d. wavelength/2.e. wavelength/20.
Answer:
d. wavelength/2.
Explanation:
The circular motion of water molecules extends from regions of shallow water to deep water. It ranges from a depth, H < L/20 for shallow water to a depth of H > L/2 for deep water where L is the wavelength of the wave.
For depths greater than L/2,the circular motion is not affected by the wave energy. So, the maximum depth for the circular motion is L/2 = wavelength/2.

Solución
La velocidad instantánea está dada por,
v = dx / dt = pendiente de la curva x-t
aquí, del gráfico:
en x = 1 m ---> t = 8 s
en x = 3 m ---> t = 0 s
entonces, dx = 1-3 = -2 m
dt = 8-0 = 8 s
Entonces,
v = -2/8
v = -0,25 m / s
Dado que, pseed es una cantidad escalar.
Entonces, velocidad instantánea = | v | = 0,25 m / s
Two glass rods are rubbed together. One of the glass rods are brought near (but
does not touch) an uncharged pith ball. Would you expect the pith ball to attract,
repel, or do nothing? Explain why.
Answer:
The correct answer is - do nothing.
Explanation:
If two same or identical objects, in this instance two glass rods, were rubbed together they neither attract nor repel each other as there is no transfer of electrons from one material to the other material as there is no difference in their charges.
Only two different objects are able to transfer electrons from one material to the other material if rubbed together, to produce the conditions for static electricity to be observed. Therefore there would be no charge on the glass rod so there would be no charge to balls to repel or attract.

A 25 kg child is riding on a swing. If the child travels 8.9 m/s at the bottom of their swing, how high into the air is the child able to swing?
Answer:
h = 4.04 m
Explanation:
Given that,
Mass of a child, m = 25 kg
The speed of the child at the bottom of the swing is 8.9 m/s
We need to find the height in the air is the child is able to swing. Let the height is h. Using the conservation of energy such that,
[tex]mgh=\dfrac{1}{2}mv^2\\\\h=\dfrac{v^2}{2g}[/tex]
Put all the values,
[tex]h=\dfrac{(8.9)^2}{2\times 9.8}\\\\h=4.04\ m[/tex]
So, the child is able to go at a height of 4.04 m.
2ZnS plus 2O2 yields 2ZnO plus SO2 what is number in each category and is it balanced or unbalanced
Answer:
2 ZnS + 3O2 ---> 2ZnO + 2 SO2
Explanation:
2 ZnS + 2O2 ---> 2ZnO + SO2
There are 2 Zn atom on the LHS and 2 Zn on the RHS. Hence the Zn is balanced on both sides of the equation.
There are two S atom on the LHS but there is only one S atom on the RHS.
Hence we will balance the S atoms
2 ZnS + 2O2 ---> 2ZnO + 2 SO2
Now the oxygen is unbalanced as there are three oxygen molecule on the RHS but only two on the LHS.
Hence, the balanced equation would be
2 ZnS + 3O2 ---> 2ZnO + 2 SO2

______________________________A 120 volt refrigerator uses 650 watts. Calculate how much work is done by the refrigerator in one hour?
Answer:
2,340,000 J
Explanation:
Work done can be described as when energy or force is applied to an object to cause displacement
Work done is measured in joules
1 Watt = 1 Joule / second
650 watts = 650 Joules / second
convert 650 joules to seconds by multiplying by 3600
650 x 3600 = 2,340,000 J
Why do the planets orbit the Sun in an elliptical shape?
Answer:
That's essentially how objects in orbits work as they move closer to the body they orbit, they accelerate faster and faster. Our penny will get so fast that, once it comes around the planet, it will be flung very far away, which will then slow it down. This is what creates an elliptical orbit.
Explanation:
You have a grindstone (a disk) that is 98.0 kg, has a 0.335-m radius, and is turning at 100 rpm, and you press a steel axe against it with a radial force of 23.6 N. Assuming the kinetic coefficient of friction between steel and stone is 0.192, calculate the angular acceleration of the grindstone.
Answer:
[tex]a=0.276[/tex]
Explanation:
From the question we are told that:
Mass [tex]m=98.kg[/tex]
Radius [tex]r=0.335[/tex]
Angular velocity [tex]\omega=100rpm[/tex]
Radial force of [tex]F_r=23.6 N.[/tex]
Kinetic coefficient of friction [tex]\mu=0.192[/tex]
Generally the equation for Kinetic Force is mathematically given by
[tex]F_k=\mu.F_r[/tex]
[tex]F_k=0.192*23.6[/tex]
[tex]F_k=4.5312[/tex]
Generally the equation for Torque on Center is mathematically given by
[tex]Ia=f_k*r[/tex]
Where
[tex]I=\frac{Mr^2}{2}[/tex]
Therefore
[tex]a=\frac{2f_k}{Mr}[/tex]
[tex]a=\frac{2*4.5312}{98*0.335}[/tex]
[tex]a=0.276[/tex]
Therefore Angular acceleration of the grindstone is
[tex]a=0.276[/tex]
