What is uniform acceleration

Physics
1 answer:
kotegsom [21]3 years ago
5 0

Answer:

It means zero acceleration.

Explanation:

When a body moves with constant velocity then it is said to be there is no rate of change of velocity takes place because it is constant. So the acceleration becomes zero or uniform acceleration.

A 7.0 kg bowling ball has a moment of inertia of 2.8x10-2 kg m2, and a radius of 0.10 m. If it rolls down the lane at an angular
slega [8]

Hi there!

Angular momentum is equivalent to:

\large\boxed{L = I\omega}

L = angular momentum (kgm²/s)

I = moment of inertia (kgm²)

ω = angular velocity (rad/sec)

Plug in the given values for moment of inertia and angular speed:

L = (0.028)(40) = \boxed{1.12 kgm^2/s}

A 9.00-cm-long wire is pulled along a U-shaped conducting rail in a perpendicular magnetic field. The total resistance of the wi
m_a_m_a [10]

Answer:

<em>0.45 N</em>

Explanation:

<em>Let Recall that,</em>

<em> The power formula is:  </em>

<em>   P = E²/R  </em>

Let A = the magnetic field  

<em>Let L = length of wire  = 9.00cm = 0.09 m  </em>

let  R = resistance of wire  = 0.320 Ω

let v =  velocity of the wire = 4 m/s  

<em>Let E = across the wire voltage </em>

Let P = the power of the wire = 4.3 W  

To Solve  for E:  

<em>The formula of E = √PR  </em>

The Voltage from  a magnetic field is given as,

E = vAL  

We therefore Use E = E

√PR = vAL  

to solve  for A,

A= √PR/vL  

BA= √4.3(0.32)/(4)(.09)  -=0.173

A = 0.173 wA/m²

Let F  be  the pulling force  

Let I  be the current in the wire  

P = I²R  

<em>I = √P/R  </em>

F = IAL  

F = √P/RAL  

F = √4.3/.32(0.173)(.09)  

<em>F = 0.45N</em>
