Answer:

.409 N

Explanation:

For this to balance, the moments around the fulcrum must sum to zero.

On the left you have   .21   ( is that down? I will assume it is)

      Counterclockwise moments :

        .21 * 40     +  1.0 * 20    

     Clockwise moments :

        .5 * 20     +     F * 45

these moments must equal each other

.21*40 + 1 *20   =  .5 * 20 + F * 45

   F = .409 N

if solid figures have parallel bases and lateral faces how the base will be perpendicular the lateral face​
Sonja [21]

Each face of a solid figure is called either a base or a lateral face. Solid figures generally have one or two bases. If it has two, these bases are parallel. If a figure has two parallel bases and lateral faces, such as in a prism, the bases will be perpendicular to the lateral faces.

(c) The plates are moved farther apart with each plate maintaining the same net charge. In a coherent paragraph-length response,
katrin2010 [14]

Answer:

Energy is applied on the charge to do work.

Explanation:

Work is only be done when one charge moves against the electric field of anther charge that require huge amount of energy because both have same charge and the force of repulsion occurs between them. Work is defined as the product of force and displacement so from this equation we can conclude that work is done when a force is applied on an object and it moves in the direction in which force is applied. If the force or energy is removed from the charge which is present in the electric field of another charge so it moves away from that charge and the work is also be done..

If a seagull drops a shell from rest at a height of 12 m how fast is the shell moving when it hits the rocks
Dvinal [7]

As seagull drops a shell from rest at a height of 12 m, so we use kinematic equation of motion,

v^{2} = u^{2} +2g h

Here, h is the height, u is initial velocity , v is final velocity and g is acceleration due to gravity.

Given,  h = 12 m.

We take, g = 9.8 \ m/s^2 and u = 0 because seagull drops a  shell from rest.

Therefore, the speed of shell when it hits the rocks,

v^{2} = 0 + 2 \times 9.8 m/s^2 \times 12 \ m = 235.2 (m/s)^2 \\\\ v = \sqrt{235.2 (m/s)^2} = 15.33 \ m/s^2

This question is typical on some driver’s license exams: A car moving at 45 km/h skids 15 m with locked brakes. How far will the
sergiy2304 [10]

from kinematics equation if we know that final speed is ZERO and initial speed is given that due to constant deceleration the object will stop in some distance "d" and this distance can be calculated by kinematics

v_f^2 - v_i^2 = 2 a d

0 - v^2 = 2(a)d

here acceleration due to friction will be same at all different speed

so for 45 km/h speed the distance of stop is 15 m

while at other speed 112.5 km/h the distance will be unknown

now we will have

0 - 45^2 = 2(a)15

0 - 112.5^2 = 2(a)d

now divide above two equations

\frac{45^2}{112.5^2} = \frac{15}{d}

d = 93.75 m

So it will stop in distance 93.75 m
