When you look at the backside of a shiny teaspoon held at arm's length, do you see yourself upright or upside down? (b) When you
igor_vitrenko [27]

Answer:

a) The back spoon gives a right image (upright)

b) the front gives an inverted image

Explanation:

The spoon is a curved metallic object, when we see ourselves from the back we have a convex mirror, in this type of mirror when the law of reflection is applied the rays diverge therefore the eye-brain system forms the image with the prolongation of the rays, therefore the image is straight and smaller than the object.

When we look through the deep side of the spoon, we have a concave mirror and as the object (we) is further away than the distance, the rays converge to a point, so the image is real, inverted smaller than the object.

In summary.

a) The back spoon gives a right image (upright)

b) the front gives an inverted image

Light of wavelength 575 nm passes through a double-slit and the third order bright fringe is seen at an angle of 6.5^degree away
Anon25 [30]

Answer:

The correct option is C

Explanation:

From the question we are told that

   The wavelength is  \lambda  =  575 *10^{-9} \  m

    The  angle is  \theta  =  6.5^o

    The order of maxima  is  n =  3

Generally for  constructive interference

       dsin \theta  =  n  *  \lambda

=>   d =  \frac{n  *  \lambda }{  sin \theta }

=>   d =  \frac{3   *  575 *10^{-9} }{  sin 6.5  }

=>   d = 15.24 *10^{-6} \  m

=>  d = 15 \mu  m

4. An object is moving with an initial velocity of 9 m/s. It accelerates at a rate of 1.5
Nata [24]

Answer:

11.9 m/s

*<em>But</em><em> </em><em>if</em><em> </em><em>you</em><em> </em><em>need</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>with</em><em> </em><em>sig</em><em> </em><em>figs</em><em> </em><em>it</em><em> </em><em>should</em><em> </em><em>be</em><em> </em><em>10m</em><em>/</em><em>s</em><em> </em><em>(</em><em>1sf</em><em>)</em><em> </em><em>or</em><em> </em><em>12m</em><em>/</em><em>s</em><em> </em><em>(</em><em>2sf</em><em>)</em>

Explanation:

{vf}^{2}  -  {vi}^{2}  = 2ad

{vf}^{2}  = 2ad +  {vi}^{2}

{vf}^{2}  = 2 \times 1.5 \times 20 +  {9}^{2}

{vf}^{2}  = 60 + 81

{vf}^{2}  = 141

vf =  \sqrt{141}

vf = 11.874

Backpackers often use canisters of white gas to fuel a cooking stove's burner. If one canister contains 1.45 L of white gas, and
lorasvet [3.4K]

Answer: One canister contains 1.03 Kg of fuel,

Explanation:

The density is defined as the relation between the mass and the volume p=\frac{m}{v}

First of all you need to have the same units for volume and density, so:

For the volume,

1.45 L * \frac{1.10*10^{-3}m^{3}  }{1 L} = 1.45 *10^{-3} m^{3}

For the density,

p = 0.710\frac{g}{cm^{3} } *\frac{1cm^{3} }{1*10^{-6}m^{3}  }*\frac{1 Kg}{1*10^{3}g } = 710\frac{Kg}{m^{3} }

From the density equation we have m=p*v, so:

710\frac{Kg}{m^{3} } *1.45*10^{-3} m^{3} = 1.03Kg
