What is true when an object is moved farther from a plane mirror?
musickatia [10]

Answer:

For a plane mirror, the image distance equals the object distance, so the image distance will increase as the object distance increases

The height of the image stays the same and the image distance increases.)

Explanation:

For plane mirrors, the object distance (is equal to the image distance. That is the image is the same distance behind the mirror as the object is in front of the mirror. If you stand a distance of 2 meters from a plane mirror, you must look at a location 2 meters behind the mirror in order to view your image

Answer:

Habitat manipulation

Explanation:

Habitat manipulation, otherwise known as ecological engineering, is a technique of promoting natural enemies within an ecosystem by making thriving conditions more suitable for them.

<em>In this case, thriving conditions for the species (which happens to be predators and hence, natural enemies) were promoted via artificial introduction of food. </em>

a voltmeter and an ammeter are used to respectively monitor the voltage across the current through the resistor
dusya [7]

When a current is established in a closed conducting loop , we use ammeter. Due to this resultant potential developed detected by voltmeter.

  1. When current flows through loop , it gets conducted.
  2. Due to this Electric field is generated . This happens due to induced magnetic field.
  3. The free electrons were at rest until current is there , still ammeter detects some deflection.
  4. This deflection is due to zero current.
  5. Due to magnetic field , current in coil changes.
  6. Mathematically, \alpha =-\frac{d\beta }{dt}
  7. The presence of conducting loop is not necessary for having electric field.

e= -\frac{d\beta }{dt}

e=-L\frac{d\beta }{dt}

i= i0 \left \{ {{y=0.63} \atop {x=t}} \right.

i=0.63 io

The current theory of the structure of the
irina1246 [14]

Answer:

pt 1: m=1.66698*10^{21} kg

Pt 2: KE=1212.23531 J

Explanation:

Information Given: (p = density)

l = 5200km  d = 35km p = 2700kg/m^{2}

Part 1: Mass

  • Find volume
  1. V=(l)^2(d)
  2. V=(4.2*10^6)^2(35*10^3)
  3. V=61.74*10^{16}
  • Find Mass
  1. m=Vp
  2. m=(61.74*10^{16})(2700)
  3. m=1.66698*10^{21}

Part 2: Kinetic Energy

  1. v=\frac{3.8cm}{yr}*\frac{m}{100cm}*\frac{yr}{365d}*\frac{d}{24hr}*\frac{hr}{3600s}
  2. v=1.20497*10^{-9}

KE=\frac{1}{2}mv^2

KE=\frac{1}{2} (1.66698*10^{21})(1.20497*10^{-9})^2

KE=1212.23531 J

Part 3: Jogger Speed

set up, because I don't have the mass :(

Information given:

KE_{jogger}

  1. KE=\frac{1}{2}mv^2
  2. v_{jogger} =\sqrt{\frac{2KE}{m_{jogger} } }
  • Input the values

Hope it helps :)
