The magnitude of the centripetal acceleration of the car as it goes round the curve is 4.8 m/s²
<h3>Circular motion</h3>
From the question, we are to determine the magnitude of the centripetal acceleration.
Centripetal acceleration can be calculated by using the formula
![a_{c} =\frac{v^{2} }{r}](https://tex.z-dn.net/?f=a_%7Bc%7D%20%3D%5Cfrac%7Bv%5E%7B2%7D%20%7D%7Br%7D%20)
Where
is the centripetal acceleration
is the velocity
and
is the radius
From the given information
![v = 12 \ m/s](https://tex.z-dn.net/?f=v%20%3D%2012%20%5C%20m%2Fs)
and ![r = 30 \ m](https://tex.z-dn.net/?f=r%20%3D%2030%20%5C%20m)
Therefore,
![a_{c} =\frac{12^{2} }{30}](https://tex.z-dn.net/?f=a_%7Bc%7D%20%3D%5Cfrac%7B12%5E%7B2%7D%20%7D%7B30%7D%20)
![a_{c} =\frac{144 }{30}](https://tex.z-dn.net/?f=a_%7Bc%7D%20%3D%5Cfrac%7B144%20%7D%7B30%7D%20)
![a_{c} = 4.8\ m/s^{2}](https://tex.z-dn.net/?f=a_%7Bc%7D%20%3D%204.8%5C%20m%2Fs%5E%7B2%7D%20)
Hence, the magnitude of the centripetal acceleration of the car as it goes round the curve is 4.8 m/s²

Climate change may affect tropical cyclones in a variety of ways: an intensification of rainfall and wind speed, a decrease in overall frequency, an increase in frequency of very intense storms and a poleward extension of where the cyclones reach maximum intensity are among the possible consequences
Answer:
if it is a plastic connector it wont work but if there is metal or steel it will work
Explanation:
Objects should be cooled before their mass is determined on a sensitive balance because it could damage the balance. Also, because it would give you wrong reading of the mass. Hot objects would warm the air around it. A warm air would expand and would produce convection as it rises causing to give the object a mass that is less than the actual. Another reason would be it would cause instability in the readings, the mass would fluctuate every now and then due to the convection currents around the object. It is always recommended to weigh the masses of objects that are in room temperature.
300 miles / 6 hours = 50 miles per hour
