The frequency of the George Washington Bridge is 2.05 Hz. What is its period?
Zina [86]

Answer: 0.5 seconds

Explanation:

Given that:

Frequency of the George Washington Bridge F = 2.05 Hz

Period T = ?

Recall that frequency is the number of cycles a wave can complete in one second. Hence, frequency is the inverse of period.

i.e F = 1/T

2.05Hz = 1/T

T = 1/2.05Hz

T = 0.488 seconds (Rounded to the nearest tenth as 0.5seconds)

Thus, the period of the George Washington Bridge is 0.5 seconds

Two positive charges ( 8.0 mC and 2.0 mC) are separated by 300 m. A third charge is placed at distance r from the 8.0 mC charge
WINSTONCH [101]

Answer:

r=200m

Explanation:

From the question we are told that:

Charges:

Q_1=8.0mC

Q_2=2.0mC

Q_3=8.mC

Distance d=300m

Generally the equation for Force is mathematically given by

F=\frac{kq_1q_2}{r^2}

Therefore

F_{32}=F_{31}

\frac{q_2}{(300-r)^2}=\frac{q_1}{r^2}

\frac{2*10^{-3}}{(300-r)^2}=\frac{8*10^{-3}}{r^2}

r=2(300-r)

r=200m

The fishing pole shown here is an example of a lever. Which statement describes the fishing pole's mechanical advantage?
luda_lava [24]

Answer:

Explanation:

The person will exert a much larger force to take a fish out of the water than the fish itself weighs. The advantage of the fishing pole, however, is that it moves the fish a large distance, from the water to the boat or the shore.
