Answer:
The distance of the image produced by the concave mirror is 11.27 cm.
Explanation:
Given that,
Focal length = 8.40 cm
Distance between object and plane mirror = 11.0 cm
Distance between plane mirror and concave mirror = 22.0 cm
We need to calculate the object distance
![u =11.0+22.0 = 33.0\ cm](https://tex.z-dn.net/?f=u%20%3D11.0%2B22.0%20%3D%2033.0%5C%20cm)
We need to calculate the distance of the image
Using formula of distance of the image
![v=\dfrac{uf}{u-f}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7Buf%7D%7Bu-f%7D)
Where, u = Object distance
f = focal length
Put the value into the formula
![v=\dfrac{33.0\times8.40}{33.0-8.40}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B33.0%5Ctimes8.40%7D%7B33.0-8.40%7D)
![v=11.27\ cm](https://tex.z-dn.net/?f=v%3D11.27%5C%20cm)
Hence, The distance of the image produced by the concave mirror is 11.27 cm.
The correct answer is option C. insulator.
An insulator material<span> has a high resistivity and prevents the movement of electrons. It is a hindrance in the path of electrons & resists the current flow.
The conductor conducts electrons as it offers very less resistance. A battery provides voltage to the circuit.
Hence, option (c) is correct. </span>
Answer:
The giraffe is the tallest of all mammals. It reaches an overall height of 18 ft (5.5 m) or more. The legs and neck are extremely long. The giraffe has a short body, a tufted tail, a short mane, and short skin-covered horns
Answer:
The two important tendons in the knee are (1) the quadriceps tendon connecting the quadriceps muscle, which lies on the front of the thigh, to the patella and (2) the patellar tendon connecting the patella to the tibia (technically, this is a ligament because it connects two bones).
P is disproportional to t, which means that if P increases with x factor, the t will decrease with the same x factor. If t increases then P decreases
