Answer:
Velocity is how fast and in what direction it moves.
Explanation:
Answer:
Three Laws
Newton's Three Laws of Motion. Sir Isaac Newton: The Universal Law of Gravitation. Sir Isaac Newton and the Unification of Physics & Astronomy.
Explanation:
Explanation:
Acceleration is the change in velocity over time.
a = Δv / Δt
a = (26 m/s − 9 m/s) / 8 s
a ≈ 2.1 m/s²
Q = m.s.Δt
Δt = Q /m.s
Here, Q = 30,000 J
m = 390 g
s = 3.9 J/g C
Substitute their values,
= 30,000 / 390 *3.9
= 30,000 / 1521
= -20 C (approx.) [-ve sign 'cause temperature is decreasing ]
In short, Your Answer would be Option D
Hope this helps!
