Andru [333]3 years ago
4 0

Answer:

We know that an image is a picture of an object while shadow is formed an object comes in between the surface and light. ... The formation of image takes place when the light rays are reflected by an object. The formation of shadow takes place when the light falls on an opaque object.

Explanation:

Image Shadow

2. We are able to see images when light refraction enters our eyes.

In the case of shadow no light enters our eyes.

3. Image contains colour, structure etc. of the object.

Shadow does not give any information about the object as it is colourless

How old is a bone if it still has 50% of its carbon-14 content?
Degger [83]

Answer:

5730 years

Explanation:

The half life of carbon-14 is 5730 years.  If 50% of the carbon-14 remains, then exactly 1 half life has passed.

The half-life equation is:

A = A₀ (½)^(t / T)

where A is the remaining amount,

A₀ is the initial amount,

t is time,

and T is the half life.

In this case, A = ½ A₀ and T = 5730.

½ A₀ = A₀ (½)^(t / 5730)

½ = (½)^(t / 5730)

1 = t / 5730

t = 5730

a hiker walks 200 m west and then walks 100 m north in what direction is her resulting displacement draw to show your answer​
Sliva [168]

Answer:

The direction of the displacement is in North-West.

Explanation:

Resultant displacement D is

=\sqrt{(200)^{2} + (100)^{2} } \\=223.60m                        

Here the direction is

\Theta =tan^{^{-1}}\left ( \frac{100}{200} \right )\\\Theta =26.6^{o}

Then the direction is 26.6^{o} North-west.

A brick sits on the top of a hill with a gravitational potential energy of 245 J. To determine the gravitational potential of th
Bogdan [553]

Answer:

The mass of the object, its acceleration due to gravity and the distance between the top of the hill and the ground level.

Explanation:

gravitational potential energy is the energy possessed by a body under influence of gravitational force by virtue of its position.

In order to determine the gravitational potential energy of the brick, we must know the mass (m) of the brick, its acceleration due to gravity (g) since it is acting under the influence of gravitational force and the distance between the top of the hill and the ground level. (The height).

Potential energy of a body is calculated as mass × acceleration due to gravity × height.
