A metal cylinder measures 3.0 cm in diameter, is 12.0 cm high, and has a mass of 750 g. The cylinder hangs from a string attache
kvasek [131]

Answer with Explanation:

We are given that

Diameter of cylinder,d_1=3 cm

Radius,r_1=\frac{d_1}{2}=\frac{3}{2}=1.5cm=1.5\times 10^{-2} m

1m=100 cm

Height,h=12 cm=\frac{12}{100}=0.12 m

Mass,m=750 g=\frac{750}{1000}=0.75kg

1kg=1000 g

Diameter of beaker,d_2=10 cm

Radius of beaker,r_2=\frac{d_2}{2}=\frac{10}{2}=5cm

A.\pi r^2_2h_2=\pi r^2_1 h_1

h_2=\frac{r^2_1}{r^2_2}h

h_2=\frac{(1.5)^2}{(5)^2}\times 12=1.08 cm

Hence, the height of the water in the beaker rises when the cylinder is submerged=1.08 cm

B.Weight read on the scale after the cylinder is submerged

w=mg-\rho A_1h_1g

Where g=9.8 m/s^2

A_1=\pi r^2_1

Density of water=\rho=1000kg/m^3

w=0.75\times 9.8-1000\times \pi(1.5\times 10^{-2})^2\times 0.12\times 9.8

w=6.52 N

Estefan has determined his BMI at 31. Explain how he can apply the FITT training principles to improve his body composition.
-BARSIC- [3]
Frequency:

Cardio : Five or more 
HIIT: 5 or 4

Strength: 2-3 days on non-consecutive days a week
 
Intensity:
How hard you work during the session

For cardio : workout at your target heart rate.
For HIIT: varying intensity from high to low or rest ( no slow pace)
For strength: you should lift enough weight to complete the needed number of reps and sets.

Time:

For cardio 30- 60 min
For HIIT 45 min (short periods of bursts followed by rest)

For strength depends on the amount of weight.

Type:

Either cardio, HIIT or strength training (resistance training) 

NOTE: This info is given by an unqualified brofessor, who uses his hard gained bro-science in the expense of scientific facts to solve others broblems.
