What is formula for acceleration given the mass and force?

Newton's second law F=ma can be rearranged to give acceleration: a=F/m


How much acceleration with result when 450N of force acts on 30kg?

What you mean to say is: "The net force acting on the ball is 30 N."F = M AA = F / M = (30) / (4) = 7.5 m/s2


What determines energy in sound waves?

By the frequency. The higher the frequency, the shorter the wavelength. The lower the frequency the longer the wave length. C= L * f C = Time in milliseconds (343 m/s @ 20 degrees C , L= Wave Length or Lambda in meters and f= frequency in Hertz A little algebra and you have; L= C/f Example; 343 m/s / 100 Hz = .343 meters Frequency is a function of time, cycles per second. Time is the reciprocal of frequency (1/f= T).


How are male and female pelves different?

This is best seen using pictures. (M) is male, (F) is female. General appearance: (M) More massive,rougher, heavier processes. (F) Less massive, smoother, more delicate processes. Tilt: (M) Upper end of pelvis relatively vertical. (F) Upper end of pelvis tilted forward. Ilium: (M) Deeper, projects farther above sacroiliac joint. (F) Shallower, does not project as far above sacroiliac joint. Sacrum: (M) narrower and deeper. (F) Wider and shallower. Coccyx: (M) less movable, more vertical. (F) more movable, tilted posteriorly. Width of greater pelvis: (M) Anterior superior spines closer together, hips less flared. (F) Anterior superior spines farther apart, hips more flared. Pelvic inlet: (M) Heart shaped. (F) Round or oval. Pelvic outlet: (M) Smaller. (F) Larger. Pubic symphysis: (M) Taller. (F) Shorter. Greater Sciatic notch: (M) Narrower. (F) Wider. Obturator Foramen: (M) Round. (F) Triangular to oval. Acetabulum: (M) Larger, faces more laterally. (F) Smaller, faces slightly anteriorly. Pubic arch: (M) Usually 90o or less. (F) Usually greater than 100o


What would be the resulting acceleration if a 7.0 kg shot put was launched with a force of 140 N?

The resulting acceleration would be 20 m/s^2. This can be calculated using the formula a = F/m, where F is the force applied (140 N) and m is the mass of the shot put (7.0 kg).
