Diverging lens=concave lens

The image would be after the first focal point but before the lens and it will be smaller than the object. Look at my picture for reference. Please let me know if this helped you!

Why do the pipes in a steam-heating system need to be insulated?
qaws [65]

Answer:

1. Increase Efficiency: Insulating the condensate or hot water return lines reduces heat loss from the water returning to the boiler. The hotter the water returning to the boiler is, the quicker it is to convert back to steam, which takes less energy to accomplish.

Two objects, one of mass m and the other of mass 2m, are dropped from the top of a building. when they hit the ground

Objects in space that are moving at a constant velocity in a straight line ___________.
nikdorinn [45]
The best answer is A) <span>keep moving at a constant velocity until some forces act on them

As the man you're probably tired of hearing about said:

"Every object persists in its state of rest or in uniform motion in a straight line unless a new force acts upon it" 
This is Isaac Newton's 1st law of motion, or the law of inertia. 

Put more simply, objects in motion tend to stay in motion, and tend the maintain the same velocity (direction and speed) and objects at rest tend to stay at rest. </span>

Calculate the force at sea level that a boy of mass 50 kg exerts on a chair in which he is sitting.
kogti [31]

As per the question the mass of the boy is 50 kg.

The boy sits on a chair.

We are asked to calculate the force exerted by the boy on the chair at sea level.

The force exerted by boy on the chair while sitting on it is nothing else except the force of gravity of earth i.e the weight of the body .The direction of that force is vertically downward.

At sea level the acceleration due to gravity g = 9.8 m/s^2

Hence the weight of the boy w = mg  [m is the mass of the body]

we have m = 50 kg.

                             Hence w = 50 kg ×9.8 m/s^2

                                             =490 N kg m/s^2

                                              = 490 N

Here newton [N] is the unit of force.
