How can a small spark start a huge explosion? using electric forces and molecules
OLga [1]

Answer:

Small sparks can lead to huge explosion if they are left unattended.

Explanation:

Small sparks are not harmful but if these sparks happen near some hazardous material or object then it could lead to heavy explosion. If there is some chemical substance near the spark or there are magnetic lines which can explode the spark then these minor sparks could result in heavy disastrous explosion.

An object in uniform circular motion must be changing its speed in order move in a circular path
mafiozo [28]

Answer:

False

Explanation:

An object in uniform circular motion must be changing its velocity in order to move in a circular path.

In fact, remind that velocity is a vector which consists of a magnitude (the speed) and a direction.

When an object is moving in uniform circular motion, the direction of the motion is constantly changing (since the trajectory is a circle): so, this means that the velocity is also changing. However, this does not imply that the speed of the object is changing. In fact, in a uniform circular motion, the speed of the object remains constant.

A horizontal spring is lying on a frictionless surface. One end of the spring is attached to a wall, and the other end is connec
Wewaii [24]

Answer:

Velocity = 0.4762 m/s

Explanation:

Given the details for the simple harmonic motion from the question as:

Angular frequency, ω = 12 rad/s

Amplitude, A = 0.060 m

Displacement, y = 0.045 m

The initial Energy =  U  = (1/2) kA²    

where A is the amplitude and k is the spring constant.

The final energy is potential and kinetic energy

   K + U =   (1/2) mv²   + (1/2) kx²  

where  x  is the displacement

m is the mass of the object

v is the speed of the object

Since energy is conservative. So, the final and initial energies are equal  as:

   (1/2) k A²   = (1/2) m v²   + (1/2) kx²  

Using,   ω² = k/m, we get:  

Velocity:

v=\omega\times \sqrt{[ A^2 - y^2 ]}

v=\omega\times \sqrt{[ {0.06}^2 - {0.045}^2 ]}

<u>Velocity = 0.4762 m/s</u>
