Answer:
Electromagnetism has important scientific and technological applications. It is used in many electrical appliances to generate desired magnetic fields. It is even used in a electric generator to produce magnetic fields for electromagnetic induction to occur. It has many more technological applications including MRI scanning (magnetic resonance imaging) and electric bells.
Explanation:
Electromagnets are widely used as components of other electrical devices, such as motors, generators, electromechanical solenoids, relays, loudspeakers, hard disks, MRI machines, scientific instruments, and magnetic separation equipment.
Answer:
The height reached by the material on Earth is 91 km.
Explanation:
Given that,
Mass 
Radius = 1821 km
Height 
Suppose we need to find that how high would this material go on earth if it were ejected with the same speed as on Io?
We need to calculate the acceleration due to gravity on Io
Using formula of gravity
Put the value into the formula
Let v be the speed at which the material is ejected.
We need to calculate the height
Using the formula of height
Using ratio of height of earth and height of Io
Put the value into the formula
Hence, The height reached by the material on Earth is 91 km.
Answer:
mass is the amount of "matter" in an object. weight is the force exerted on an object by gravity
Explanation:
Answer: here are some of the places that use nuclear fusion
Commonwealth Fusion Systems (CFS)
TAE Technologies.
General Fusion (Canada)
Helion Energy.
Tokamak Energy (U.K.)
First Light (U.K.)
Explanation: nuclear fusion is a nuclear reaction in which atomic nuclei of low atomic number fuse to form a heavier nucleus with the release of energy.
