False. this is just a physical change, not a chemical change.
V-V₀=at
a=(V-V₀)/t
a=(10-20)/5=-2 m/s²
Acceleration of the car is -2 m/s²
We have: Q = m.s.Δt
m = Q / s.Δt
Here, Q = 19.4 J
s = 6.28 J/g C
Δt = 22.9
Substitute their values into the expression:
m = 19.4 / 6.28×22.9
m = 19.4 / 143.81
m = 0.135 g
In short, Your Answer would be Option A
Hope this helps!
Answer:
Maritime polar air masses form over the northern Atlantic ocean
Explanation:
Maritime polar (mP) air masses are cool, moist, and also unstable. Some maritime polar air masses arise as continental polar air masses over Asia and move westward over the Pacific, gathering warmth and moisture from the ocean. .
Answer:
They are deflected as Earth’s magnetic field exerts force on them.
Explanation:
(Not for cheating, Just to help)
As solar wind approaches Earth, what happens to the charged electrons?
They are absorbed as Earth’s magnetic field exerts force on them.
They grow stronger as Earth’s magnetic field exerts force on them.
They grow weaker as Earth’s magnetic field exerts force on them.
They are deflected as Earth’s magnetic field exerts force on them.
