Answer:
d
Step-by-step explanation:
The mass of the pendulum does not affect the period and frequency
The period can be determined using the formula:
T = 2π √(L/g)
where L is the length of the rope
and g is the acceleration due to gravity = 9.8 m/s2
Plugging in the values:
T = 2π √(5/9.8)
T = 10π/7 = 4.49 s
And for the frequency:
f = 1/T
f = 1/4.49
f = 0.22 Hz
Answer: (7/8)x gallons
Explanation:
Let x be the amount of gasoline at the start of the trip.
During the trip the car uses 1/8 gallons of gasoline
Which mean it uses 1/8 of the original gasoline, (1/8)x.
Gasoline left in the tank:
x - (1/8)x = (7/8)x
