Answer:
Pseudoscience
Explanation:
Predicting future events in a person's life based on the lines on the palm of the hand is an example of Pseudoscience. A pseudoscience is a false science that makes claims based on faulty or nonexistent scientific evidence and often characterized by contradictory, excessive claims, etc. These types of Pseudoscientific beliefs are common due to widespread "scientific illiteracy among different societies.
Answer:
Explanation:
Assuming uniform spread of sound with no significant reflections or absorption. We know that sound intensity varies 
where r is the distance
Since intensity is given then when at 3 m
Since we have the constant then at 4m
Intensity, 
Answer:
when the object goes from the focal length to twice the focal length the image goes from infinity to twice the focal length, this image is real and inverted
Explanation:
Let's use the constructor equation to describe the image of a concave mirror
1 / f = 1 / p + 1q
where f is the focal length, p and q the distance to the object and the image, respectively
1 /q = 1/f - 1/p
tell us that the image is between the focal and twice the focal, let's calculate the position of the image
for both ends
case 1, distance to the object p = f
1 / q = 1 / f -1 / f
1 / q = 0
q = ∞
the image is in infinity
case2, distance to object p = 2f
1 / q = 1 / f - 1 / 2f
1 / q = 1 / 2f
q = 2f
the image is twice the focal length, the object and the image are at the same point
therefore the image when the object goes from the focal length to twice the focal length the image goes from infinity to twice the focal length, this image is real and inverted
Answer:
D
Explanation:
The crust of the Earth is broken into many pieces called plates. The plates "float" on the soft, plastic mantle which is located below the crust, aka asthenosphere
