a 4lb ball is travelling in a circle radius 3ft speed 6ft/s. the attached cord pulled through the center has constant speed 2ft/
lora16 [44]

Answer:

Explanation:

Circle motion

Weight=4lb

Radius=3ft

Velocity Vb= 6ft/s

Velocity Vr=2ft/s

Velocity Vo=12

V2=√Vo²+Vr²

12=√Vo²+2²

Square both side

144=Vo²+4

Vo²=140

Vo=11.83ft/s

Applying conservation of angular momentum

Ha1=Hb2

MbVbr1=MbVor2

r2=Vbr1/Vo

r2=6×3/11.83

r2=1.52ft

The require time is written as.

∆r=Vrt

t=∆r/Vr

t=r1-r2/Vr

t=3-1.52/2

t=0.74sec

Radioactive nuclei decay to become unstable. Is this true or false?
Damm [24]

The unstable nuclei undergo radioactive decay. The nucleus decay in form of emitting the radiations or changing into the different chemical element.

Thus, the nucleus decay takes place till the nuclei become stable.

Hence, given statement is false.

A nonmechanical water meter could utilize the Hall effect by applying a magnetic field across a metal pipe and measuring the Hal
Serga [27]

Answer:

The velocity is  v =2.455 \  m/s

Explanation:

From the question we are told that  

   The diameter of the pipe is  d =  4.25 \ cm  = 0.0425 \ m

    The magnetic field is  B  =  0.575 \  T

     The hall voltage is  V_H =  60.0 mV  =  60 *10^{-3} \  V

Generally the average fluid velocity is mathematically represented as

          v = \frac{V}{ B  *  d }

=>       v = \frac{60*10^{-3}}{ 0.575   *  0.0425  }

=>       v =2.455 \  m/s

Will pushing on a car always change the cars mechanical energy?what must happen for the cars kinetic energy to increase?
riadik2000 [5.3K]
1) Pushing on a car will not always change the car's mechanical energy, but it does change yours since your physically using most of your energy to push the car.
 
2) In order for a cars kinetic energy to increase, the car has to be in motion when it is going down a hill, because when you go down hills and objects like that; you tend to increase in kinetic energy.

What type of energy is released when a firecracker explodes
Ludmilka [50]

-- Sound energy.  That's how you hear it explode.

-- Light energy.  That's how you see it in the sky.

-- Heat energy.  That's why you get burned if sparks fall on you.

-- Potential energy, as all the pieces fall to the ground.

These were all stored in it as chemical energy before it exploded.
