Answer:
Es útil porque al saberlo evitas sobrexponerte a problemas como <em><u>enfermedades, desgarros o daños a largo plazo de tu cuerpo.</u></em>
Explanation:
When a person decides to start exercising or some type of physical activity, it is necessary for him to know how much his body can resist that activity during a defined period of time.
If in some way or another your body does not resist physical activity, you can hurt yourself, tear a ligament or muscle or get sick.
One of the most common diseases that almost nobody notices is the increase in circulatory and heart problems.
It is best to know your physical condition, how much weight you can carry with weights, or how long you can last doing physical activities.
Answer:17.44A
Explanation: Current density=I/Area
Area is given by 2.79mm^2=2.79×10^-6m^2
Current=I=current density ×Area=6.25×10^6 ×2.79×10^-6=17.44A
<h3><u>Answer</u>;</h3>
≈ 5 Kgm²/sec
<h3><u>Explanation</u>;</h3>
Angular momentum is given by the formula
L = Iω, where I is the moment of inertia and ω is the angular speed.
I = mr², where m is the mass and r is the radius
= 0.65 × 0.7²
= 0.3185
Angular speed, ω = v/r
= (2 × 3.142 × r × 2.5) r
= 15.71
Therefore;
Angular momentum = Iω
= 0.3185 × 15.71
= 5.003635
<u>≈ 5 Kgm²/sec</u>
Answer: 2.74
Explanation:
We can solve this problem using the stopping distance formula:
Where:
is the distance traveled by the car before it stops
is the car's initial velocity
is the coefficient of friction between the road and the tires
is the acceleration due gravity
Isolating :
Solving:
This is the coefficient of friction
