Answer:
f = 0.0833 Hz
Explanation:
Frequency is defined as the no. of cycles per unit time. The frequency of water waves can be given by the following formula:
here,
No. of Waves = No. of times seagull moves up and down = 5
Time = 1 minute = 60 sec
Therefore, using these values in the formula, we get:
<u>f = 0.0833 Hz</u>
3) The force of Gravity no longer works, aka you lose gravity.
4) What are the ideas? I can't see them.
Answer:
Acceleration a = 3.75 m/s^2
Explanation:
Given that
Mass M1 = mass of the truck = 2300kg
Mass M2 = mass of the SUV = 2500kg
Force applied F = 18000N
From Newton second law,
F = ma
Where a = acceleration
We must consider the entire mass involved in the system. Therefore,
F = (M1 + M2)a
Make a the subject of formula
a = F/(M1 + M2)
Acceleration a = 18000/( 2300 + 2500)
Acceleration a = 18000/ 4800
Acceleration a = 3.75 m/s^2
Answer:
Reading is close to (b) 13.44 which is the best estimate of the period
Associated error,
Given:
Solution:
1.The best estimate of the period can be calculated by the mean of the measurements and the one closest to the mean is the best estimate of the measurement:
It is close to 13.44 s
2. Associated error is given by:
where
n = a, b,......, e
Now,
Mean Absolute Error,
3. The assumption behind the estimation is population is considered to distributed normally.
-- Doubling one mass doubles the product of the masses, and
doubles the strength of the gravitational forces between them.
-- Tripling the distance between them changes the strength of the
gravitational forces between them by the factor of
1 / 3² = 1 / 9 .
-- The new gravitational force between the objects is
( 2 / 9 ) = 22.2%
of the strength of the original gravitational force.
