The difference between the majority viewpoint and the minority view is that the majority group is made to feel normal and the minority group is made to feel divergent.
What is the viewpoint?A vantage point or point of view from which something is viewed or assessed is known as the viewpoint The story is narrated from a variety of perspectives, including two major ones and several smaller ones.
Most studies comparing majority versus minority influence argue the author, places a premium on influence in the sense of prevailing. In this context.
There is evidence that majorities have greater public influence than minorities, and that minority impact when it happens, is mostly latent. In the current version,

If the electric potential in a region is given by v(x)=7/x2 the x component of the electric field in that region is
Hi there!
Recall that:
[tex]\Delta V = -\int\limits^a_b {E \cdot } \, dx[/tex]
Given an electric field, the potential difference can be solved by using integration. Similarly:
[tex]E = -\frac{dV}{dx}[/tex]
We can differentiate the electric potential equation to solve for the electric field.
Use the power rule:
[tex]\frac{dy}{dx} x^n = nx^{n - 1}[/tex]
Differentiate the given equation.
[tex]-\frac{dV}{dx}\frac{7}{x^2} =- \frac{dV}{dx}7x^{-2} = -(-14x^{-3}) = \frac{14}{x^3}[/tex]
Or:
[tex]\boxed{E(x) = \frac{14}{x^3}}[/tex]
The component of the electric field in that region is E = 14/x³ if the electric potential in a region is given by v(x)=7/x2
What is an electric field?An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.
We have:
The electric potential in a region is given by:
[tex]\rm V(x) = \frac{7}{x^2}[/tex]
We know the relation between potential difference and an electric field is given by:
[tex]\rm \triangle V = \int\limits^a_b {E.} \, dx[/tex]
If the electric field is given, then:
[tex]\rm E = -\frac{dV}{dx}[/tex]
[tex]\rm E = -\frac{d(7x^{-2} )}{dx}[/tex]
After differentiate:
[tex]\rm E = -(-14x^{-3})[/tex] or
[tex]\rm E = \frac{14}{x^3}[/tex]
Thus, the component of the electric field in that region is E = 14/x³ if the electric potential in a region is given by v(x)=7/x2

The distance of the source of light from the object.
The angle at which the light rays fall on the object.
The size of the opaque object.
The size of the shadow depends on the distance of the source of light and on the angle at which the light rays fall on the object.
If the source of light is closer to the object, a larger shadow is formed than when the source of light is far from the object.

If a peregrine falcon dove at its maximum speed for half a mile to catch prey, how many seconds would the dive take? (round your answer to the nearest second. ) correct answer9
The number of seconds that the dive will take if peregrine falcon dove at its maximum speed for half a mile is 9 seconds.
How to calculate the time?From the complete information, it was stated that the peregrine falcon can reach speed of up to 200 miles per hour.
Therefore, the number of seconds that the dice would take for half a mile will be calculated thus:
1 hour = 200 miles
3600 seconds = 200 miles
1 second will be: = (200/3600) = 0.056 miles
Therefore, the time will be:
200miles / 1 hour = 0.x

Why is glass a good insulator? (1 point)
O The atoms in glass hold on tightly to their positively charged particles.
O The atoms in glass do not hold on tightly to their positivelycharged particles.
The atoms in glass do not hold on
Glass is known to be a good insulator because atoms in glass hold on tightly to their positively charged particles.
What is an insulator?Insulators are those substances that do not conduct heat or electricity like their conductor counterparts.
Conduction of electric charges is as a result of the free flow of electrons in the atom of the substance.
Hence, a good insulator holds on tightly to its electrons and prevent them from flowing freely to conduct electric charges.

When using a different calorimeter, and mixing 50 ml of hot water at 65 degrees c with 60 ml of water in the calorimete
The specific heat capacity of the calorimeter used in mixing the water is determined as 21.87 J/g⁰C.
Conseervation of energyThe heat capacity of the calirometer is determined by applying the principle of conservation of energy.
Heat lost by the hot water = Heat gained by the calirometer
[tex]Q _w = Q_c\\\\M_w C_w\Delta \theta _w = M_c C_c\Delta \theta _c[/tex]

If the cooking pot is 0.2 meters tall, how long is the wavelength of the resonance created?
What is an estimate for the speed of sound in this situation?
You may discover that the speed of sound seems a bit off. Write down some ideas on why that is.
(a) The wavelength of the resonance created is 0.8 m.
(b) The speed of the sound in the fundamental mode is 400 m/s.
(c) The low value of speed of speed of sound in water calculated may be as a result of low temperature of the water poured into the cooking pot.
Wavelength of the resonance createdThe wavelength of the resonance created is determined by assuming the cooking pot to be a closed pipe.
Wavelength of fundamental mode of a closed pile = 4L
where;
L is length of the pipeλ = 4 x 0.2 = 0.8 m
Estimated speed of soundThe speed of the sound in the fundamental mode is calculated as follows;
