A particle moving along a straight line with constant acceleration has a velocity of 3.26 m/s at t = 2.22 s, and a velocity of -6.59 m/s at t = 5.72 s. what is the particle's acceleration in m/s2?

Why does the input force have to be greater than the force needed to lift the bale?

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?

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths
