The aspect of his fitness program that could keep the young man from achieving his goal would potentially be the exercise with his friend. His friend could be a hindrance to his motivation to do more or to continue. If he's so attached with exercising with his friend and his friend decides to stop, then he would probably lose motivation.
Answer: 6611.715 joules
Explanation:
Q = MxCxdeltaT = 6959.7 which is 100%
95% = 6611.715
Answer:
Pressure = force/area
= 650N/0.12m^2
= 5416.7 to 1 d.p
I got 650N by taking the gravitational field on earth to be 10N/kg.
Weight = mass x gravitational field
= 65 x 10N/kg
= 650
Answer is 5416.7 pascals (Pa)
Or
5308.3 Pa
if gravitational field was taken to be 9.8N/kg
Hope this helps!
Answer:
1. f=1T. where: f is the frequency of the wave in hertz. T is the period of the wave in seconds.
2. f=vλ where: f is the frequency of the wave in hertz. v is the velocity of the wave in meters per second. λ is the wavelength of the wave in meters
3. f=cλ
