Why should we change away from using incandescent light bulbs

Physics
1 answer:
Maurinko [17]3 years ago
8 0

They are energy inefficient

Explanation:

The main reason why we must change away from using incandescent lighting bulbs is because of their energy inefficiency.

  • Much of the power consumed is used in producing heat in an incandescent bulb.
  • Therefore, they are energy inefficient.
  • Energy saving bulbs produces less heat and they are more durable.
  • Most energy saving bulbs are typically more expensive.
  • Most incandescent bulbs are also not environmentally friendly.

A 5 kg block moves in a straight line on a horizontal frictionless surface under the influence of a force that varies with posit
jekas [21]

The work done is 315 J

Explanation:

The graph is missing: find it in attachment.

The work done by a variable force is given by

W=\int F(x) dx

where

F(x) is the magnitude of the force

x is the position

On a force vs position graph, the work done is equivalent to the area under the graph. Therefore, in order to find the work done as the block moves from x = 0 to x = 8.0 m, we have to calculate the area under the graph between these two points.

Each square corresponds (vertically) to 45 N, so the area of the first trapezium between x = 0 and x = 4.0 m is

A_1 = \frac{(4+2)\cdot 2\cdot 45)}{2}=270

Then we have to find the area of the triangle between x = 6.0 m and x = 8.0 m:

A_2 = \frac{1}{2}(2)(45)=45

Therefore, the total area (and the work done) is

W=A_1+A_2=270+45=315 J

The aqueous humor in a person's eye is exerting a force of 0.242 N on the 1.21 cm2 area of the cornea. What pressure is this in
Virty [35]

Answer:

<h2><em>15.00124mmHg</em></h2>

Explanation:

Pressure is defined as the ratio of force applied to an object to its area.

Pressure = Force/Area

Given parameters

Force = 0.242N

Area = 1.21cm²

Required parameters

Pressure = 0.242/1.21

Pressure = 0.2N/cm²

Using the conversion to convert the pressure to mmHg

1N/cm² = 75.0062mmHg

0.2N/cm² = y

y = 0.2 * 75.0062

y = 15.00124mmHg

<em>Hence the pressure in mmHg is 15.00124mmHg</em>
