Electromagnetic radiation is one of many ways as energy travels through space.
 As you may already know, a wave has a valley (lowest point) and a ridge (highest point). The vertical distance between the tip of the crest and the central axis of the wave is known as amplitude. This is the property associated with the brightness, or intensity, of the wave. The horizontal distance between two consecutive crests or valleys of the wave is known as wavelength

Answer:

A. The volume of the object

Explanation:

First of all, it can only PROBABLY be A or D

But why is it only A?

  • Mass = The amount of matter in an object (nothing related here)
  • Volume = How much space is the object taking (super related here)

It's VOLUME here and not MASS here because:

  • It it would be Mass, then the object size could be anything, but the liquid wouldn't move as much higher.
  • But because it is Volume, it is taking space, which makes the liquid move
  • If the Mass would be the answer, then it would be totally not related, because mass isn't related over here, it matters about size.

<h2>Hence, A. The volume of the object </h2>

is your answer!!!!

in as small room fan of rating 50 watt is used for 10hrs 2bulb of rating 10v are used for 8hrs daily.calculate monthly. electric
Pie

Answer:

The electric bill for June is Rs198000

Explanation:

Convert volt to watt, but in order to do so I need to know the amps and since it is not provided I converted if the amps was 1.

I multiple 50 with 10 then  with 30 so I know how much watt the fan takes at June.

Since there are 2 light bulb I multiple 10 with 2 than with 8 than with 30.

15000 watts for the fan,

4800 watts for light bulb,

add them and then times it by 10.

Rs198000

Of the three forces acting on the rock as it slides down the bowl, which (if any) are constant and which are not? explain.
choli [55]

Answer

Hi,

The forces are; weight (gravity), Normal/centripetal force and friction. Force due to gravity is constant where as friction and centripetal are not.

Explanation

Weight is constant, given by the force of gravity on the object. The centripetal force is a function of the angles occurring between the velocity vector and the weight vector that is at right angle with the perpendicular line drawn from the surface. Friction is a function of the centripetal force thus it also varies.

Hope this helps!
