1Talk to your doctor
Don't start any exercise program without first checking with your primary care provider. Your doctor can determine whether you're healthy enough to exercise, and what, if any, modifications you'll need to make to your program. "Exercise programs should be customized to the individual whenever possible to account for any limitations and ongoing medical conditions," Dr. Berkson advises.
2 Choose your workout carefully
High-impact exercise programs aren't ideal for women with conditions like arthritis or osteoporosis. Non-impact exercises, including swimming or using an elliptical exercise machine, will give you aerobic conditioning without stressing your joints.
3 Learn the proper technique
Don't start any new exercise without first learning the correct form. On the right is an example of proper squat technique. To learn the right form, work with a trainer at home or in the gym, or consult a physical therapist to help you tailor a workout to your health conditions and physical capabilities.
4 Get the right gear
Buy a pair of sturdy, comfortable sneakers that provide good arch support and have a cushioned heel to absorb shock. Wear loose, comfortable clothing that gives you room to move and breathe.
5 Start gradually
Don't jump into a new exercise program. "The greatest risk of injury comes with changing an exercise program or adding a new exercise," Dr. Berkson says. Start slowly. If you're cycling, for example, set the bike's controls on the lowest speed and tension, and pedal for just a few minutes your first few times. Gradually increase the speed and intensity only when you feel ready.
Answer:
(3a + 4b)² / a²b²
Explanation:
This question is difficult to interpret, however the concept being tested in this question is the ability to simplify fractions with variables.
It is a basic rule that only like terms (as denominators) can be added and subtracted from each other, however if you need to add or subtract two fractions with different denominators, it is important to make sure you create a common denominator.
For example, in the beginning, the first fractions are:
16/a² + 24/ab + 9/b²
So it is important to make sure there is a common denominator between all 3 fractions. An easy way of doing this would be to multiply denominators together:
(16b²)/a²b² + (9a²)/a²b² + 24/ab
(9a²+16b²)/a²b² + 24/ab
So now it has gone from 3 fractions to 2, and then to 1:
(9a²+16b²)/a²b² + 24ab/a²b²
(9a² + 24ab + 16b²) / a²b²
Then all that needs to be done is simplify the numerator:
(3a + 4b)² / a²b²
Answer:
<em>Never</em>
Explanation:
In a reversible adiabatic process, there is not transfer of heat or matter between the system and its environment. An adiabatic reversible process is a process with constant entropy, i.e ΔQ=0. The internal energy is solely dependent on the work done either due to compression or expansion. So the entropy of the gas will never increase.
Answer: b) False
Explanation:Ceramic is brittle in nature therefore it has a tendency that it is strong during the compression and it tends to be weak during the high tensile forces. While the tensile forces are applied , ceramics are not able to yield the stress and cause breakage of the material due to high tension but does not face any fault during the compression.
Answer:
The growth rate is the dependent variable and that is option D
Explanation:
Since the study is based on the growth rate of babies which will be dependent on how the babies are fed - bottle fed and breast fed as pointed out in the question. This implies that Growth rate will be the dependent variable since it values will be dependent on the independent variable which are the bottle fed and breast fed, these may be manipulated or altered as the case may be.
