Answer:

Mechanical solidarity is the social integration of members of a society who have common values and beliefs. ... In contrast to mechanical solidarity, organic solidarity is social integration that arises out of the need of individuals for one another's services.

An amount of work W is done on an object of mass m initially at rest, and as result it winds up moving at speed v. Suppose inste

sesenic [268]

Answer:

Explanation:

Given

W amount of work is done on the system such that it acquires v velocity after operation(initial velocity)

According to work energy theorem work done by all the forces is equal to change in kinetic energy of object

$W=\frac{1}{2}mv^2---1$

where m=mass of object

v=velocity of object

When the object is already have velocity v then the final speed is given by work energy theorem

$W=\frac{1}{2}mv_f^2-\frac{1}{2}mv^2-----2$

From 1 and 2 we get

$\frac{1}{2}mv^2=\frac{1}{2}mv_f^2-\frac{1}{2}mv^2$

$2\times \frac{1}{2}mv^2=\frac{1}{2}mv_f^2$

$v_f^2=2v^2$

$v_f=\sqrt{2}v$

Cathode rays are negatively charged

Explanation:

Thomson's cathode ray beam bent towards the positively charged plate. With this information, he was able to conclude that the rays were negatively charged.

Cathode rays were discovered by J.J. Thomson based on his experiment on the gas discharge tube. He was able to discover some of the properties of the wave.

One notable one was that he observed that the rays deflected towards the positively charged plate.

Since unlike poles attract then he concluded that the cathode rays were negatively charged.

An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 1760 1760 × 103 seconds (a

Katen [24]

Answer:

$a_c=6.471\frac{m}{s^{2}}$

Explanation:

We can calculate the magnitude of the tangential velocity of the moon, using the equation:

$v=\frac{2\pi R}{\tau}$

(This works, since velocity is defined as distance over time; in this case the distance is 2πR and the time is the period τ)

Next, from the equation of the centripetal acceleration we have:

$a_c=\frac{v^{2} }{R}\\\\a_c=\frac{4\pi^{2}R}{\tau^{2} }$

Be careful, the radius of the orbit R is equal to the distance from the center of the moon to the center of the planet. So we have to sum the distance from the center of the moon to the surface of the planet and the radius of the planet to obtain R:

$R=285.0*10^{6} m+3.50*10^{6} m=288.5*10^{6}m$

Finally, plugging the given values into the centripetal acceleration formula, we have:

$a_c=\frac{4(3.141)^{2}(288.5*10^{6}m)}{(1760*10^{3}s)^{2}} =6.471\frac{m}{s^{2}}$

In words, the moon's radial acceleration a_c is 6.471m/s².

Calculate the change in potential energy of a 91.2 kg man when he takes an elevator from the first floor to 37th floor, if the d

MAXImum [283]

Answer:

128379.69 J

Explanation:

Potential energy: This can be defined as the energy of a body to to position in the gravitational field. The S.I unit of potential energy is Joules (J).

The expression for potential energy is given as,

ΔEp = mgΔH

ΔEp = mg(H₂-H₁)..................... Equation 1

Where ΔEp =change in Potential Energy, m = mass of the man, g = acceleration due to gravity, H₂ = Height of the 37th floor, H₁ = height of the first floor

Given:m = 91.2 kg, g = 9.8 m/s², H₁ = 3.99 m, H₂ = 3.99×37 = 147.63 m.

Substitute into equation 1

ΔEp = 91.2(9.8)(147.63-3.99)

ΔEp = 893.76(143.64)

ΔEp = 128379.69 J.
