A typical long-period seimometer has a period of 30 seconds and a Q of about 2 . As a result of a violent earthquake the Earth's surface may oscillate with a period of about 20minutes and with an amplitude such that the maximum acceleration is about 10^-9 meter per second sqaure. How small a value of A must be observable if this is to be detected?​

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.
