Veroncas velocity was measured as 4.3m/s she displace 20 meters in 4.7 seconds witch piece of imformation is misssing for the correct calculation of velocity

If a spring has a k value of 100 newtons per meter and it is stretched 0.50 meters, what is the restoring force of the spring?

The speed of light can be used to measure the

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
