A resistor R, inductor L and capacitor C are connected in series to a power supply that is operating at the resonant frequency of the circuit. If another capacitor C is placed in series with the previous capacitor without changing anything else, the phase angle in the new circuit is . .

A. -90° < φ < 0 meaning current leads voltage
B. 0 < φ < 90° meaning voltage leads current
C. -90° < φ < 0 meaning voltage leads current
D. 0 < ф < 90° meaning current leads voltage
E. φ = 0 meaning voltage is in phase with current

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.

use photo math tells u all the answers thats what i use
