2. A circuit contains, in series, a generator
(4.5 V; 1.5 2) and two resistors R1 = 25
12 and R2 = 18.5 12. Calculate the
current in the circuit by:
a. Applying the law of uniqueness of the
voltage between the terminals of the
generator

What are atoms of the same element with varying number of neutrons

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?

Am i correct on these two physics questions?
