A soccer player extends her lower leg in a kicking motion by exerting a force with the muscle above the knee in the front of her
lisabon 2012 [21]

Answer:

10.09 N

Explanation:

Analogously to Newton's second law, torque can be defined as:

\tau=I\alpha

Here, I is the moment of inertia and \alpha is the angular acceleration. We have:

\tau=(0.65kg*m^2)(29.5\frac{rad}{s^2})\\\tau=19.18N*m

Torque is the vector product of the position vector of the point at which the force is applied by the force vector:

\vec{\tau}=\vec{r}\times \vec{F}

Since the effective lever arm is perpendicular to the force, the angle between them is 90^\circ. The magnitud of this vector product is defined as:

\tau=rFsen\theta.

Solving for F and replacing the known values:

F=\frac{\tau}{rsen\theta}\\F=\frac{19.18N*m}{1.9m(sen90^\circ)}\\F=10.09N

Boyle's Law states that as the pressure on a gas increases at constant temperature the volume of the gas
elena55 [62]
Boyle’s law is P1V1 = P2V2. This shows that pressure and volume have an inverse relationship, so increase in pressure causes a decrease in volume. B is your answer

Andreas93 [3]

Answer:

The given symbol is of DC power source

Option A is incorrect because in ammeter a letter  A is written inside a circle.

Similarly, Option B is incorrect because in voltmeter V is written inside a circle

Option C  and D are  incorrect

Option E is correct it is a DC power source.

It is a Dc power source the left hand side is positive side and the right line is the negative side.
