Answer: 0.25m/s2
Explanation:
Acceleration is change in velocity with time
V = final velocity = 5m/s
U =Initial velocity = 3m/s
t = time = 8s
a = Acceleration =?
a = V — U / t
a = (5 — 3) / 8
a = 2/8
a = 0.25m/s2
Answer: 1.25 miles per minute
Explanation:
Average speed is the rate of change of total distance covered per unit time.
i.e Average speed = (Total distance / Time taken)
Total distance covered = (25miles + 40 miles + 70 miles + 15 miles)
= 150 miles
Total time taken = ( 15 minutes + 30 minutes + 1 hour + 15 minutes) = 120 minutes
Since 60 minutes = 1 hour, the total time taken is 120 minutes
Now, apply Average speed = (Total distance / Time taken)
= (150 miles / 120 minutes)
= 1.25 miles per minutes
Thus, Joseph drove with an average speed of 1.25 miles per minute.
Answer:
The correct answer is a) lonic Bond
Explanation:
Lithium fluoride (LiF) is a salt, formed by an ionic bond between a metal (Li) compound and a nonmetal (F).
Answer:
As the amplitude of pendulum motion increases, the period lengthens, because the restoring force −mgsinθ increases more slowly than −mgθ (sinθ≅θ−θ3/3!for small angles).
