A one-repetition maximum is most important in developing muscle strength.

Further Explanation:

Muscular strength is the total force you can apply or the total weight you can lift on the other hand in endurance how many times we can move that weight without getting tired.

Muscular strength and endurance work simultaneously. If we have muscular strength we can endure the weight of any heavy object. They help us to make our bones stronger and less fragile.

Muscular strength is important in health for so many reasons:

• Increase body capability to do more activities like chopping wood, lifting boxes, opening doors without being tired.

• Reduce the risk of injury.

• Help to make a healthy body.

• Help to make stronger muscles, healthier, and bones.

• Help us to try different exercise into our fitness program.

To test the muscular strength we perform one repetition maximum test. In this test, a individual repeat one exercise to check muscle strength.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
