The oxygen molecule, O2, has a total mass of 5.30×10-26 kg and a rotational inertia of 1.94×10-46 kg-m2 about an axis perpendicu
Nady [450]

Answer:

\omega=2.85*10^{13}\frac{rad}{s}

Explanation:

The translational kinetic energy depends on the mass and speed of the body, as follows:

K_T=\frac{mv^2}{2}\\K_T=\frac{5.30*10^{-26}kg(1.49*10^3\frac{m}{s})^2}{2}\\\\K_T=1.18*10^{-19}J

While rotational kinetic energy depends on the moment of inertia and the angular velocity of the body, as follows:

K_R=\frac{I\omega^2}{2}(1). We know that:

K_R=\frac{2}{3}K_T(2)

Replacing (1) in (2):

\frac{I\omega^2}{2}=\frac{2}{3}K_T\\\\\omega=\sqrt{\frac{4}{3}\frac{K_T}{I}}\\\omega=\sqrt{\frac{4}{3}\frac{1.18*10^{-19}J}{1.94*10^{-46}kg\cdot m^2}}\\\omega=2.85*10^{13}\frac{rad}{s}

1. (I) If the magnetic field in a traveling EM wave has a peak magnitude of 17.5 nT at a given point, what is the peak magnitude
Elan Coil [88]

Answer:

The electric field is E  =  5.25 V/m

Explanation:

From the question we are told that

    The peak magnitude of the magnetic field is  B  =  17.5 nT  =  17.5 *10^{-9}\ T

Generally the peak magnitude of the electric field is mathematically represented as

         E  =  c  *  B

Where c is the speed of light with value c  =  3.0 *10^{8} \ m/s

So

       E  =  3.0 *10^{8}  *  17.5 *10^{-9}

       E  =  5.25 V/m

A 50 kg skater pushes off from a wall with a force of 200 N. What is the skater's acceleration?
lutik1710 [3]

Answer:

Explanation:

mass (m) = 50 kg

Force (F) = 200 N

Acceleration (a)= ?

WE know

F = m * a

200 = 50 * a

a = 200 / 50

a = 4 m/s²

Hope it will help :)
