True lizards can stick to surfaces because their bulbous toes are covered in hundreds of tiny microscopic hairs called setae
<h3><u>Answer;</u></h3>
Light bounces off of the mirror and then appears to come from behind the mirror.
<h3><u>Explanation;</u></h3>
- <u><em>Plane mirrors form images that are virtual, upright and the same size and shape as the object it is reflecting.</em></u>
- <em><u>When rays of light from the object hits a plane mirror they bounces off the mirror,that is they undergo reflection, and appear to originate from behind the mirror, resulting to the formation of a virtual image.</u></em>
- The image formed appears to be behind the plane in which the mirror lies. A virtual image is an image that is formed at a location from which the rays of light appear to come from. The image can not be formed on a screen.

Answer:
a. 3.6 units
b. 1.4 units
c. 3.6 units
d. 6.1 units
Explanation:
The length of a vector is given by the following formula:
Length = √(x² + y²)
where,
x = x-component of vector
y = y-component of vector
a.
Here,
x = 2
y = 3
Therefore,
Length = √(2² + 3²)
Length = √13
<u>Length = 3.6 units</u>
<u />
b.
Here,
x = 1
y = 1
Therefore,
Length = √(1² + 1²)
Length = √2
<u>Length = 1.4 units</u>
<u />
c.
Here,
x = 2
y = -3
Therefore,
Length = √(2² + (-3)²)
Length = √13
<u>Length = 3.6 units</u>
<u />
d.
Here,
x = 1
y = -6
Therefore,
Length = √(1² + (-6)²)
Length = √37
<u>Length = 6.1 units</u>
Power = (voltage) · (current)
71 W = (120 V) · (current)
Divide each side by (120 V) :
Current = (71 W) / (120 V) = 0.59167 Amperes
What I want to know is: Where can I buy a 71-W light bulb ?
