<span>Animal Y is an invertebrate, and animal Z is a vertebrate.
An x-ray can produce images of structures found inside the body. Based on the image, you can see that Animal Z has a backbone, which is a series of small bones called vertebrae that extend from the head. Animal Y does not have that structure.
Vertebrates are organisms that have a backbone and invertebrates are organisms that lack one. </span>
Air gap means that the dielectric is air.
So <span>ε0 = </span><span>8.85 x 10^-12 [F/m].......................permitivity of free space
Lets use the equation
</span>C= ( ε0x A) / d
Where A is the area of the plate
And d the distance between the plates
d = <span>3.2-mm = 3.2 E-3 m
so ............> A = C *d /</span>ε0 = 0.20 F * 3.2 E-3 m / 8.85 x 10^-12 [F/m]
A = 7.23 E 7 [m2]
Heat is transferred to the driver's hands by conduction. The direct contact between the steering wheel and the driver's hands allows heat from molecules on the surface of the steering wheel to transfer to the molecules on the surface of the driver's hands. This is in contrast to convection (which requires a fluid in between the two surfaces that transfers heat).
Answer:
149.96J
Explanation:
Given parameters:
Number of stairs = 33
Height = 0.25m
Weight = 599.85N
Unknown:
Energy the person takes to reach the top = ?
Solution:
To solve this problem;
The energy it takes is given as:
Energy = weight x height
Energy = mass x gravity x height
Now,
Insert the given parameters and solve;
Energy = 599.85 x 0.25 = 149.96J
Answer:
Suppose that you are looking at the reflex candle in one mirror.
The image in the mirror is called the "virtual image"
If the real candle is at a distance of, let's say, 5 meters from the mirror, then the virtual image in the mirror will be also 5 meters "inside" the mirror.
Now, the light that emanates from the candle in the reflex seems to come from the virtual image, 5 meters inside of the mirror, but this is obviously not the real case.
The rays come, originally, from the real candle, and then those rays are reflected in the surface of the mirror.
Then the rays of the virtual image actually come from the surface of the mirror and not from the virtual image itself
