A particle oscillates harmonically x = A cos(ωt + φ0), with amplitude 9 m, angular frequency π s −1, and initial phase π 3 radia
Gekata [30.6K]

Answer:

t = \frac{5}{12} s

Explanation:

As we know that the equation of particle position is given as

x = A cos(\omega t + \phi_0)

Now the speed of the particle is given as

v = A\omega sin(\omega t + \phi_0)

now we know that potential energy and kinetic energy is equal

so we have

\frac{1}{2} mv^2 = \frac{1}{2}kx^2

so we will have

A^2\omega^2 sin^2(\omega t + \phi_0) = A^2\omega^2 cos^2(\omega t + \phi_0)

tan^2(\omega t + \phi_0) = 1

\omega t + \phi_0 = \frac{\pi}{4} or \frac{3\pi}{4}

\pi t = \frac{3\pi}{4} - \frac{\pi}{3}

\pi t = \frac{5\pi}{12}

t = \frac{5}{12} s

Assume that segment r exerts a force of magnitude t on segment l. what is the magnitude flr of the force exerted on segment r by
mrs_skeptik [129]
If we are talking on the force being exerted by a segment of a rope of lenght R on the right on a point M which is being also pulled from the Left by a segment of rope R  as shown in the figure attached. Then we invoke Newton's Third Law:
"Any force exerted by an object (in this case a segment of the rope) also suffers a equal and opposite force".
If we pick T_R=T whis is the tension exerted by the right segment then the left segment will also exert an equal and opposite force so we have that T_L=-T

A child is prescribed a drug X; the recommended manufacturer’s dose is 2.50 mg/m2. The body surface area (BSA) of the child is 1
guapka [62]

Answer: 3.75 mg

Explanation:

We need a dose of 2.50 mg per square meter of BSA, and we also know that the BSA of the child is 1.50 m^2, then if the dosage should be 2.50mg for one m^2, for 1,5 m^2 we should administrate an amount of:

D = 1.5 m^2*(2.50mg/m^2) = 1.5*2.5 mg = 3.75 mg
