Answer:
a) w = 31.4 rad / s, b) a = 118.4 m / s²
Explanation:
a) let's reduce to the SI system
w = 5 rev / s (2pi rad / 1 rev)
w = 31.4 rad / s
b) the expression for the centripetal acceleration is
a = v² / r
linear and angular variables are related
v = w r
we substitute
a = w² r
a = 31.4² 0.120
a = 118.4 m / s²
Answer:
B. The particles that make up material B have more mass than the
particles that make up material A.
Explanation:
Which ramp is going to make the ball travel down faster?
The 2nd ramp because it is steeper and would give the ball a faster push caused by gravity than the 1st ramp.
A day is 24 hours so you divide the distance in a day by the number of hours in a day.
25,992/24=1083.
Answer: 1083 mph
Wave A has a higher amplitude than Wave B.
