  • Same as initial velocity.
  • Acceleration due to gravity is 9.8m/s^2

Which is constant on the whole way of travel of the ball.

As no change in acceleration there is no change in velocity at end and it remains at 3m/s

Two pulleys are fastened together to form an integral unit. At a certain instant, the indicated belt tensions act on the unit an
tresset_1 [31]

Answer:

α = 21.6 rad/s^2

Explanation:

Applying the equations of motion to determine angular acceleration of the unit,

The sum of moments about O is equal to the product of angular acceleration and moment of inertia

∑Mo = Io*α

Taking the anticlockwise direction as positive moment,

= ( -(1150) + (1400) ) * (0.5 / 2) + ( (475) - (650) ) * (0.3 / 2) - F = Io*α

= 36.5 - (2.5 N.m) =(m*ko^2)*α

NOTE: moment of inertia of the pulleys in this instance = (m*ko^2)

Hence, 33.75 = 25 * (0.25)^2 * α

Solving, α = 21.6 rad/s^2

What is the best use of an atomic model to explain the charge of the particles in Thomson’s beams?
kodGreya [7K]

Answer:

The interpretation of the subject in question is characterized in the discussion section below.

Explanation:

  • The atom seems to be the smallest particle of negatively charged electrons as well as positive. The negative particulates are comparatively small, as well as distant from both the considerably high beneficial particles. When the negative objects traveled away from the desired ones those who formed an intangible beam which was electrically charged.
  • Thomson would use a closed glass globe with just a single positive and another negative electrode with extraordinarily low present pressure. He was forced to submit those other gases to quite a voltage level, and also that the rise in popularity of emission levels, which have been called cathode rays, must have been observed.
  • As the negatives shifted away from those in the positives, an imaginary electrically conductive beam was formed. Not only that but the negative particles have been completely circumvented due to the extreme distance seen between positively and negatively particle size.
