Heat is transferred in a gas through
a unit for measuring frequency, equal to one cycle per second. if a sound wave has a frequency of 20,000 hz, this means that 20,000 waves are passing through a given point during the interval of one second.
newton's second law states that f = m x a (force is mass times acceleration). which example would have the greatest acceleration?
a) a 10 kg ball thrown with a 50 newton force
b) a 1 kg ball thrown with a 0.5 newton force
c) a 50 kg student launched by a 100 newton catapult
d) a 500 kg car accelerated by 1000 newtons from the engine
let's calculate each acceleration, from m = f/a:
a) 50n/10kg = 5 m/s^2
b) 0,5n/1kg = 0.5 m/s^2
c) 100 n/50kg = 2m/s^2
d) 1000n/500kg= 2m/s^2.
so the answer is option a.
really hope this
