Answer:
A heterogenous mixture.
Explanation:
If you added sand to your coffee, the kind of mixture your coffee would now
be is a heterogenous mixture.
A heterogenous mixture can be defined as any mixture which has a different or non-uniform composition and properties throughout any given sample of the mixture. This ultimately implies that, the constituents of a heterogenous mixture always remain separate in the sample and as such comprises of two or more phases.
Hence, a mixture of sand and coffee is simply a heterogenous mixture and can easily be separated into their various components.
Answer:
B =34.5T
Explanation:
Given E = 14.7V, L= 2.1cm = 0.021m, t = 6.50ms = 6.50×10-³s
A = L² = 0.021² = 4.41×10-⁴m²
ω = 2π/t = 2π/(6.50×10-³) = 966.64rad/s
E = ωBA
B = E/ωA = 14.7/(966.64×4.41×10-⁴)
B = 34.5T
Satellite (moon) revolve around the planet
But planet revolve around the sun.
Ganymede is a satellite(moon) which revolve around the planet jupiter. So, it is considered as moon not planet.
Simple theory.
Answer:
<h2><em><u>Is that question from class 10?</u></em></h2>
Answer:
The correct option is momentum is conserved
Explanation:
A closed system is a system that is independent/free of external factors/force and does not exchange matter with its surrounding. Since a close system is free of external factors/force; <em>acceleration is constant in it, mass is conserved in it and there will be changes in velocities of objects in the closed system</em>.
This question actually seeks to test our knowledge of the law of momentum. The law of conservation of momentum states that the momentum of a closed system is conserved.
