Answer:
F = 4.47 10⁻⁶ N
Explanation:
The expression they give for the strength of the tide is
F = 2 G m M a / r³
Where G has a value of 6.67 10⁻¹¹ N m² / kg² and M which is the mass of the Earth is worth 5.98 10²⁴ kg
They ask us to perform the calculation
F = 2 6.67 10⁻¹¹ 135 5.98 10²⁴ 13 / (6.79 10⁶)³
F = 4.47 10⁻⁶ N
This force is directed in the single line at the astronaut's mass centers and the space station
Your experiment should keep one thing constant and measure the other. So vary the temp and measure the pressure. You will get a set of data that relates pressure with temp.
<span>PV = nRT
So
P and T are directly proportional.
</span>These experiments are one of either Boyle-Mariottte's, Gay-Lussac'a or Charles' law.
The value of V is 640 km/hr.
<h3>What is Average velocity?</h3>
Average velocity is the change in position or displacement (∆x) divided by the time intervals (∆t) in which the displacement occurs.
To calculate the value of V from the question, we use the formula below.
- V' = (V+U)/2............ Equation 1
Making V the subject of the equation
- V = 2V'-U.............. Equation 2
From the question,
⇒ Given:
- V' = 520 km/hr
- U = 400 km/hr
Substitute these values into equation 2
- V = (520×2)-400
- V = 640 km/hr
Hence, the value of V is 640 km/hr.
