Answer:

The Enlightenment

Explanation:

The Enlightenment, often recognized as the Enlightenment period, was indeed a philosophical revolution that occurred during late 17th & early 18th centuries, mainly in Europe and afterward in North America.

The Enlightenment had a variety of reason-centered theories as the main source of information and intensive ideals like freedom, improvement, tolerance, brotherhood, legal governance and freedom of religion.

How many newtons of force will 2 pieces of paper have if one has a charge of .2 Coilombs and the other has a charge of .3 Coulom
sdas [7]

1) The electrostatic force between the two pieces of paper is 2.16\cdot 10^{13} N

2)

  • If the charges of the two pieces of paper are both + or both -, they repel each other
  • If the charges of one piece of paper is positive and the other one is negative, they attract each other

Explanation:

1)

The electrostatic force between two charged objects is given by Coulomb's law:

F=k\frac{q_1 q_2}{r^2}

where:

k=8.99\cdot 10^9 Nm^{-2}C^{-2} is the Coulomb's constant

q_1, q_2 are the two charges

r is the separation between the two charges

In this problem, we have the following situation:

q_1 = 0.2 C is the charge on the first piece of paper

q_2 = 0.3 C is the charge on the second piece of paper

r=0.005 m is their separation

Substituting into the equation, we find the magnitude of the electrostatic force between them:

F=k\frac{q_1 q_2}{r^2}=(8.99\cdot 10^9) \frac{(0.2)(0.3)}{(0.005)^2}=2.16\cdot 10^{13} N

2)

The electrostatic force can be either attractive of repulsive, depending on the relative sign of the charges of the objects involved.

In particular, we have:

  • If the two charges have same sign (both positive or both negative), the force between them is repulsive
  • If the two charges have opposite sign (one positive and one negative), the force between them is attractive

Therefore, in this case:

  • If the charges of the two pieces of paper are both + or both -, they repel each other
  • If the charges of one piece of paper is positive and the other one is negative, they attract each other

A hydraulic lift is made by sealing an ideal fluid inside a container with an input piston of cross-sectional area 0.004 m2 , an
kvv77 [185]

Answer:

Maximum weight that can be lifted = 18,000 N

Explanation:

Given:

Cross-sectional area of input (A1) = 0.004 m²

Cross-sectional area of the output (A2) = 1.2 m ²

Force (F) = 60 N

Computation:

Pressure on input piston (P1) = F / A1

Assume,

Maximum weight lifted by piston = W

Pressure on output piston (P2) = W / A2

We, know that

P1 = P2

[F / A1]  = [W / A2]

[60 / 0.004] = [W / 1.2]

150,00 = W / 1.2

Weight = 18,000 N

Maximum weight that can be lifted = 18,000 N

Which of the following is equal to distance divided by time?
givi [52]

To find <em>Speed </em>you divide distance by time.

Reasoning:

Displacement is the change in an object's position from the origin.

To find Acceleration you use the equation a=v^2/r

To find Velocity you divide the distance by the time it takes to travel that distance, then you add your direction to it.

<em>To find speed you use distance is over time</em>

Q. No. 9 A body falls freely from the top of a tower and during the last second of its fall, it falls through 25m. Find the heig
HACTEHA [7]

Answer:

45.6m

Explanation:

The equation for the position y of an object in free fall is:

y=-\frac{1}{2} gt^2+v_0t+y_0

With the given values in the question the equation has one unknown v₀:

v_0=\frac{y-y_0}{t}+\frac{1}{2}gt

Solving for t=1:

1) v_0=y-y_0+\frac{g}{2}

To find the hight of the tower you can use the concept of energy conservation:

The energy of the body 1 sec before it hits the ground:

2) E=\frac{1}{2}m{v_0}^2+mgy_0

If h is the height of the tower, the energy on top of the tower:

3) E=mgh

Combining equation 2 and 3 and solving for h:

4) h=\frac{{v_0}^2}{2g}+y_0

Combining equation 1 and 4:

h=\frac{{(y-y_0+\frac{g}{2}})^2}{2g}+y_0
