Answer:
D
Explanation:
This is a phenomena by a black body. A black body is reckoned to absorb all energy it receives this is because it gives off energy of different frequency ranges hence as the frequency increases the energy rises.
Answer: Worm
A virus spreads from one machine to another rapidly without human action. A virus is like a code that runes automatically without any knowledge or without taking permission of the user. It hampers the way a machine works. When a machine is attached to another machine directly or indirectly containing virus, it spreads itself. A worm is a kind of virus that can spread with zero human intervention. A virus still requires a human to download a contaminated file but worm does not. a worm can spread on its own
Answer:
D) Higher Frequency
Explanation:
Higher frequency because it says a vehicle “towards” the officer
Divide the long wire in small segments. The field due to one segment can be found from Biot- Savart law.
dB=(uo/4pi) Idlxr/r^3. In this expression if we take vector r perpendicular to current element , the cross product in the expression shows that the direction of B is perpendicular to vector r and from symmetry it can be said that field line is circular around the wire segment. This is true for all segment ,because in infinitely long wire all segments are equivalent . Thus, magnetic field lines are concentric around a long straight wire.

It’s not impossible because the gravitational pull from the earths gravity from the atmosphere will pull you in just like all other planets that’s why you can fall at really fast speeds from the air.
