Answer:
<em>Infrared telescope and camera</em>
<em></em>
Explanation:
An infrared telescope uses infrared light to detect celestial bodies. The infrared radiation is one of the known forms of electromagnetic radiation. Infrared radiation is given off by a body possessing some form of heat. All bodies above the absolute zero temperature in the universe radiates some form of heat, which can then be detected by an infrared telescope, and infrared radiation can be used to study or look into a system that is void of detectable visible light.
Stars are celestial bodies that are constantly radiating heat. In order to see a clearer picture of the these bodies, <em>Infrared images is better used, since they are able to penetrate the surrounding clouds of dust,</em> and have located many more stellar components than any other types of telescope, especially in dusty regions of star clusters like the Trapezium cluster.
An insulator is not a good source for heat or electricity to move through. Wood is an example of an insulator. The opposite of insulator is conductor. An example of a conductor is metal.
Answer:
Backwash effect
Explanation:
Your friend moved along the shore due to ; The swash effect and the Backwash effect
Swash effect is caused by the upsurge of water up along the slopping front of the beach and this same upsurge in water moves back into the beach in what is known as the backwash effect hence the movement of your friend form where they were in the surf zone to another position still within the surface zone is caused by the BACKWASH EFFECT
Answer:
Left side and center of the periodic table: metals
Right side of the periodic table: Nonmetals
Zigzag line toward right side of the periodic table: Metalloids
Explanation:
Explanation:
It is given that,
Length of the wire, L = 2.1 m
Current, I = 5.1 A
Mass of the wire, m = 0.2 kg
Let B is the magnitude of the magnetic field necessary to have this wire "float" in the Earth's gravitational field such that,
B = 0.18 T
The direction of magnetic field is given by Fleming's left hand rule. Here, the magnetic field is in +x direction.
