Answer:

<em>Correct choice: A. The acceleration is directly proportional to the net force</em>

Explanation:

Newton's Second Law of Motion

According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force F and inversely proportional to the object's mass m:

\displaystyle a=\frac{F}{m}

Correct choice: A. The acceleration is directly proportional to the net force

A charged particle is placed in an external magnetic field and it is moving in a circular path of radius 26m.The magnetic force
ElenaW [278]

Answer:

208 Joules

Explanation:

The radius of the circular path the charge moves, r = 26 m

The magnetic force acting on the charge particle, F = 16 N

Centripetal force, F_c = m·v²/r

Kinetic energy, K.E. = (1/2)·m·v²

Where;

m = The mass of the charged particle

v = The velocity of the charged particle

r = The radius of the path of the charged particle

Whereby the magnetic force acting on the charge particle = The centripetal force, we have;

F = F_c = m·v²/r = 16 N

(1/2) × r × F_c = (1/2) × r × m·v²/r = (1/2)·m·v² = K.E.

∴ (1/2) × r × F_c = (1/2) × 26 m × 16 N =  = (1/2)·m·v² = K.E.

∴ 208 Joules = K.E.

The kinetic energy of an particle moving in the circular path, K.E. = 208 Joules.

You throw a ball into a box and close the lid. You hear the ball bouncing around inside as the ball’s energy changes from gravit
beks73 [17]

Answer:

Thermal energy.

Explanation:

We know that energy is conserved and it only transform one form to another form ,Like potential energy transform in to kinetic energy when a ball fall down from a height and obtain some velocity.

In this case energy changes from gravitational energy to kinetic energy then elastic energy and after some time this energy will convert in to thermal energy.

So the answer is thermal energy.

What is the potential energy of an object that has mass of 410 kg at a height of 12m
serious [3.7K]

PE = (weight)              x (height)

     = (mass) x (gravity) x (height)

     = (410 kg) x (9.8 m/s²) x (12 m)

     =  (410 x 9.8 x 12)  kg-m²/s²

     =    48,210 joules  (rounded)

what helps differentiate between the sound of a fire truck, an ambulance and an 18 wheeler? imbre form dynamics sound
DENIUS [597]

Dynamics sound helps differentiate between the sound of a fire truck, an ambulance and an 18-wheeler.

<h3 /><h3>What is dynamics sound?</h3>

Elements allude to the din or delicateness of music. Elements offer a method for showing articulation in printed music. They help to drive the profound substance of music through volume and force. Elements can likewise be shown at the large-scale level for a piece of music in general. This may be just a single time toward the beginning, or a few times all through in the event that the din changes during various segments. Static elements are melodic directions that advise us to play the music at a specific volume that doesn't change. As such, don't get stronger or calmer, play each note at a similar volume as the final remaining one.
