The rotating parts of the right front wheel assembly of a racing car have a mass of 35 kg and are measured to be out of balance. This unbalance can be corrected by attaching a 150 g lead weight to the 375 mm diameter wheel rim. The tire has a diameter of 700 mm. The car springs have a sti ness of 50 N/mm and the tire can be considered to have a sti ness of 600 N/mm, if the tire de ection is small. If the balance correction is not made, as what speed will resonant vibration of the wheel assembly occur

explanation:

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
