Answer:

Explanation:
Acceleration is given by

where
u is the initial velocity
v is the final velocity
t is the time interval
In this problem:
is the initial velocity
is the final velocity
t = 2 s is the time
Substituting, we find the acceleration:

Answer:
Tungsten is made of tungsten while Nichrome is made of nickel chromium.
Nichrome is used in the elements of electric
devices.
Tungsten is used to make filament of bulbs.
Nichrome have high resistivity than tungsten.
Tungsten have high melting point than nichrome
Explanation:
Answer:
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).
Explanation:
Answer:
A.Moving electric charges (electrons in a circuit) creates a magnetic field and
a magnetic field can cause an electric charge to move (electricity).
