A force of 30 N is applied tangentially to the rim of a solid disk of radius 0.10 m. The disk rotates about an axis through its
den301095 [7]

Answer:

m = 4.0 Kg

Explanation:

  • Using an analogy with the Newton's 2nd law for point masses, for rigid bodies, the external net torque on a rigid body, is equal to its rotational inertia (I), times the angular acceleration (α) of the body, as follows:

       \tau_{ext} = I* \alpha (1)

  • Since the magnitude of the torque is the product of the value of the force times the perpendicular distance between the line of action of  the force and the axis of rotation, and the force is tangential to the rim of the disk, we can write the following expression:

       \tau = F*r*sin 90 = F*r (2)    

  • For a solid disk, the rotational inertia regarding an axis through its center, and perpendicular to its face is as follows:

      I = \frac{m*r^{2}}{2}  (3)

  • Replacing (3) in (1), and (2) in the left side of (1) also, we can solve for m, as follows:

       m = \frac{2*30.0N}{0.1m*150(1/s2)} = 4.0 Kg (4)

  • So, the mass of the disk is 4.0 Kg.

If the ultraviolet photon has a wavelength of 249 nm and one of the photons emitted by the fluorescent material has a wavelength
melamori03 [73]

Answer:

601 nm

Explanation:

Energy of photon having wavelength of λ nm

= \frac{1244}{\lambda}eV

Energy of 249 nm photon

=\frac{1244}{249}

=4.996 eV

Similarly energy of 425nm photon

=\frac{1244}{425}

=2.927 eV

Difference = 2.069 eV.

This energy will give rise to another photon whose wavelength will be

λ = \frac{1244}{2.069}

= 601 nm.

An apple is thrown across the cafeteria with a force of 10 N and at an acceleration of 6 m/s2. What is the mass of the apple? ..
Komok [63]

Answer:

Explanation:

F = m * a

The apple's acceleration is not influenced by the acceleration due to gravity for this question.  In real life it most certainly is influenced by gravity.

F = m * a

F = 10 Newtons.

a = 6 m/s^2

m = 10/6 = 1.66 kg. Mighty  large apple
