When an object oscillating in simple harmonic motion is at its maximum displacement from the equilibrium position, which of the

expeople1 [14]3 years ago
5 0

Answer:

speed maximum

restoring force minimum

Explanation:

When the particle executing SHM is at its mean position or equilibrium position, then its velocity is maximum and the kinetic energy is also maximum. It is because the kinetic energy is proportional to the square of the velocity as velocity maximum then kinetic energy is also maximum.

The acceleration is minimum at the equilibrium position so the restoring force is also minimum t its equilibrium position.

Which graph below represents how the velocity of the sphere changes over time when falling with constant acceleration?
Amiraneli [1.4K]

Graph B represents the velocity of the sphere changes over time when falling with constant acceleration.

  • Acceleration is the measure of how quickly a body's velocity varies with regard to time, and constant acceleration occurs when a body's velocity changes proportionately over a period of time, or at a constant rate. It measures in m/s2.
  • It is claimed that a body has continual positive acceleration when it begins to move with an initial velocity of zero and gradually increases to a positive value over time.
  • Constant positive acceleration is demonstrated by a ball falling freely in a vertical direction.

child mass 25kg moves with speed of 1.5m/s when 7.8 from the central of merry-go round. calculate the centripetal acceleration o
MAVERICK [17]

Answer:

0.2885 m/s²

Explanation:

The formula for centripetal acceleration is given as;

a_c=v^2/r

Given that;

speed = v = 1.5m/s

radius = r = 7.8

a_c=v^2/r\\\\\\a_c=1.5^2/7.8\\\\\\a_c=0.2885m/s^{2}

An isolated, irregularly shaped piece of platinum carries -8.89 × 10-9 C of charge and is in electric equilibrium. The size of t
rusak2 [61]

Answer:

c) equals V

Explanation:

This is because, since the isolated, irregularly shaped piece of platinum is in electric equilibrium, the electric potential at all points on its surface is V. So that, the potential difference across any point is zero. This implies that diametrically opposite sides have the same potential and thus, the potential at other points of the surface is V since it is in electric equilibrium.
