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,
Hence 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.

Explanation:
Simplified for you.
A body of mass 5kg is ejected vertically from the ground when a force of 600N acts on it for 0.1s. Calculate the velocity with which the body leaves the ground.
Assuming g=10N
upward force=600N(applied force)
downward force=(W)=(5x10)=50N
net force=600-50
=550N
F=(delta)P/t
(delta)P=m (v-u)
u=0m/s
(delta)P=mv
550=(5)(v)/0.1
550x0.1
55=5v
v=11m/s
there was no mention of any gravity acting on the object only applied force ,infact we aren't even given the constant

What is the term for either the number of times per second that a wave vibrates or the number of matching points that pass a location during one second? O A. Frequency B. Period O C. Wavelength D. Amplitude
The right answer is Frequency. Option A
Frequency is defined as the number of wave oscillations per unit of time and is measured in hertz. Frequency is directly proportional to pitch. Distance from the rest position to maximum shaft deflection. Frequency The number of waves he passes through a particular point per second. Measures the time it takes for a wave cycle to complete.
Maximum displacement or distance traveled by a point on the vibrating body or shaft, measured from the equilibrium position. This corresponds to half the length of the vibration path. The frequencies are opposite. The number of wave cycles to complete per second. Both amplitude and wavelength are measures of distance. Amplitude measures the height of the wave crest from the centerline. Wavelength measures the horizontal distance between cycles.

The reflection of a 10. 0 cm object appears to be 18 cm tall and 9 cm behind the mirror. What distance is the object from the mirror? cm.
The distance is the object from the mirror will be 5cm.
What is a mirror equation?A mirror equation is an equation that relates object distance and image distance to focal length. It is often referred to as a mirror formula.
The object distance in a spherical mirror is the distance between the object and the pole of the mirror (u).
The given data in the problem is;
Image height = 18cm
Object height = 10cm
u is the object distance
v is the image distance = 9 cm
From the symmetry of the triangle;

A truck with a mass of 4285 kg is moving at 9. 35 m/s. it crashes into the rear end of a larger truck with a mass of 5495 kg moving at 6. 35 m/s in the same direction. a. what is the final velocity if the trucks lock together? b. how much does the kinetic energy decrease in the collision?
(a) The final velocity if the trucks lock together after the collision is 7.66 m/s.
(b) The decrease in the kinetic energy after the collision is 11,165.1 J.
Conservation of linear momentumThe final velocity of the two truck system after the collision is determined by applying the principle of conservation of linear momentum as shown below;
m₁u₁ + m₂u₂ = v(m₁ + m₂)
4285(9.35) + 5495(6.35) = v(4285 + 5495)
74,958 = 9,780v
v = 74,958/9780
v = 7.66 m/s
Initial kinetic energy of the trucksK.E = ¹/₂mv²
K.Ei = ¹/₂(4285)(9.35)² + ¹/₂(5495)(6.35)²
K.Ei = 298,088.78 J
Final kinetic energy of the trucksK.Ef = ¹/₂(m₁ + m₂)v²
K.Ef = ¹/₂(4285 + 5495)(7.66)²
K.Ef = 286,923.68 J
Change in kinetic energyΔK.E = K.Ef - K.Ei
ΔK.E = 286,923.68 J - 298,088.78 J

Calculate the range of wavelengths that are received by the radio in a car. Suppose that the range of frequencies of FM radio is 88.0 MHz to 108 MHz.
The range of wavelengths that are received by the car radio are 2.78 m to 3.41 m.
To find the range of wavelengths, we use the equation for the speed of a wave
Speed of a waveThe speed of a wave v = fλ where
f = frequency and λ = wavelengthWhat is Wavelength?This is the distance a wave travels in one cycle of the wave.
Making λ subject of the formula, we have
λ = v/f
Given that the range of frequencies of FM radio is 88.0 MHz to 108 MHz and
v = speed of electromagnetic wave = 3 × 10⁸ m/s, f' = lowest frequency = 88.0 MHz = 88.0 × 10⁶ Hz and f" = highest frequency = 108 MHz = 108 × 10⁶ HzThe longest wavelength, λ'λ' = v/f'
= 3 × 10⁸ m/s ÷ 88.0 × 10⁶ Hz
= 0.0341 × 10² m
= 3.41 m
The shortest wavelength, λ"λ" = v/f"
= 3 × 10⁸ m/s ÷ 108 × 10⁶ Hz
= 0.0278 × 10² m
= 2.78 m
So, the range of wavelengths that are received by the car radio are 2.78 m to 3.41 m.

1. manganese dioxide is used in dey cell . ( Give reason)
2. Fuses are used in a circuit. ( Give reason )
Answer:
1.In dry cells, manganese dioxide acts as a ‘depolariser'.
In the depolarization process, the depolariser is used to remove hydrogen and doesn't allow the voltage to get reduced due to polarisation of the cell . Manganese oxide was used as a depolariser in Leclanché cell .
In zinc-carbon dry cell, the manganese dioxide takes in electrons as it is converted to Manganese III oxide (Mn2O3)
2.The fuse breaks the circuit if a fault in an appliance causes too much current flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.

If a FM radio station broadcasts at 80. 3 MHz (megahertz), what is its wavelength in m (speed of light 3. 0 x 108 m/s)
Answer:
Wavelength = 3.74 m
Explanation:
In order to find wavelength in "metres", we must first convert megahertz to hertz.
1 MHz = 1 × 10⁶ Hz
80.3 Mhz = x
x = 80.3 × 1 × 10⁶ = 8.03 × 10⁷ Hz
The formula between wave speed, frequency and wavelength is:
v = fλ [where v is wave speed, f is frequency and λ is wavelength]
Reorganise the equation and make λ the subject.
λ = v ÷ f
λ = (3 × 10⁸) ÷ (8.03 × 10⁷)
λ = 3.74 m [rounded to 3 significant figures]

what is force?Force is an external agent applied on any object to displace it from its position. Force is a vector quantity, so with magnitude it also requires direction. Direction is necessary to examine the effect of the force and to find the equilibrium of the force.
The length of each arrow represents the magnitude of each force, while the direction of each arrow represents the direction of each force.
From the diagram, we see that the four arrows have all same length: this means that the four forces have same magnitude, therefore they are balanced in pair. In fact:
On the vertical direction, the normal reaction ([tex]F_N[/tex]) balances the weight of the box ([tex]F_g[/tex])

Answer: "Most of the light waves are reflected", might be the correct answer.
Explanation: it might be the correct answer because the light waves spread out from the source in all directions, and upon striking a mirror, are reflected at an angle determined by the angle at which the light arrives. The reflection process inverts each wave back-to-front, which is why a reverse image is observed.

It depends on whether this is a "trick" question.
The law of universal gravitation says that the attractive force between two objects depends directly on their masses and inversely to the square of distance in between them.
As the objects in A are bigger than B, they MAY have higher masses. So the force is larger in A.
But no information is given about object mass or density. The distance between objects in B is shorter. So if the objects in B have the same masses those in A, then the force is larger in B.

a) What is the normal force on the car when it is at the (i)
top, (ii) rightmost and (iii) leftmost point of the track?
b) What is the speed of the car as it travels around the
vertical circle?
Answer:
The equation of equilibrium at the top of the vertical circle is:
\Sigma F = - N - m\cdot g = - m \cdot \frac{v^{2}}{R}
The speed experimented by the car is:
\frac{N}{m}+g=\frac{v^{2}}{R}
v = \sqrt{R\cdot (\frac{N}{m}+g) }
v = \sqrt{(5\,m)\cdot (\frac{6\,N}{0.8\,kg} +9.807\,\frac{kg}{m^{2}} )}
v\approx 9.302\,\frac{m}{s}
The equation of equilibrium at the bottom of the vertical circle is:
\Sigma F = N - m\cdot g = m \cdot \frac{v^{2}}{R}
The normal force on the car when it is at the bottom of the track is:
N=m\cdot (\frac{v^{2}}{R}+g )
