Answer:

Though lightning can be harvested in a safe manor, it is not very practical in many areas. Not all places get lightning storms in high amounts, so those locations would not apply, but those who do see frequent lightning can indeed use it to power. Using tall metal beams can attract the lightning and can be escorted into a power converter much like the ones used for nuclear energy.

A uniform ladder 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. The ladder weigh

dem82 [27]

Answer:

Explanation:

a )

Reaction force of the ground

R = mg

= 160 N

Maximum friction force possible

= μ x R

= μ x 160

= .4 x 160

= 64 N .

b )

160 N will act at middle point . 740N will act at distance of 3 / 5 m from the wall ,

Taking moment about top point of ladder

160 x 1.5 + 740 x 3/5 + f x 4 = 900 x 3

240 + 444 + 4f = 2700

f = 504 N

c )

Let x be the required distance.

Taking moment about top point of ladder

160 x 1.5 + 740 x 3 x / 5 + .4 x 900 x 4 = 900 x 3 ( .4 x 900 is the maximum friction possible )

240 + 444 x + 1440 = 2700

x = 2.3 m

so man can go upto 2.3 at which maximum friction acts .

If a car is moving to the left with constantvelocity, one can conclude that

jeka94

Answer:

The net force applied to the car is zero.

Explanation:

We are given that a car is moving to the left with constant velocity.

When the car moving with constant velocity

Then, the final velocity=Initial velocity

Change in velocity=Final velocity- initial velocity=0

When change in velocity is zero then , acceleration of car

$a=\frac{change\;in\;velocity}{time}=\frac{0}{t}=0$

When acceleration is zero then, By Newtons second law

$Force=Mass\times acceleration=Mass\times 0=0$

The net force applied on the car will be zero.

Option C:The net force applied to the car is zero.
