A bar on a hinge starts from rest and rotates with an angular acceleration α = 12 + 5t, where α is in rad/s2 and t is in seconds
Rama09 [41]

Answer:

Ф = 239.73 rad

Explanation:

α = 12 + 15×t

W = ∫α×dt

   = ∫(12 + 5×t)×dt

   = 12×t + 2.5×t^2

then:

Ф = ∫W×dt

   = ∫(12×t + 2.5×t^2)dt

   = 6×t^2 + 5/6×t^3

therefore the angle at t = 4.88s is:

Ф = 6×(4.88)^2 + 5/6×(4.88)^3

   = 239.73 rad

5. A ball is sitting at rest on the floor. What will happen if a balanced force is applied to the ball? *
Leno4ka [110]

When the balanced force is applied on the ball It will roll away from the force.

<u>Explanation:</u>

  • A ball lies on the floor in rest. If the balanced force is applied to

         the ball, the force will push away.

  • The forces would include gravity and the forces of air particles entering the ball from almost all directions.
  • And the ground is exercising the force and shifting away from the impact.

To have the highest magnification in a telescope, the focal length of the objective lens should be _________ and the focal lengt
Darina [25.2K]

Answer:

Large; small.

Explanation:

A telescope can be defined as an optical instrument or device which comprises of a curved mirror and lenses used for viewing distant objects i.e objects that are very far away such as stars and other planetary bodies. The first telescope was invented by Sir Isaac Newton.

To have the highest magnification in a telescope, the focal length of the objective lens should be large and the focal length of the eyepiece lens should be small.

This ultimately implies that, the eyepiece lens has a small focal length while the objective lens has a large focal length.
