The gravitational potential energy is calculated by multiplying the mass of the object to the height and the gravitational acceleration which is 9.8 m/s^2. We do as follows:

GPE = mgh
GPE = 4942
4942 = m (9.8)(6.15)
m = 82 kg 

Hope this helps.

A solid spherical conductor has a radius of 12 cm. The electric field at 24 from the center of the sphere has a magnitude of 640
hoa [83]

Answer:

Charge density on the sphere = 2.2 × 10⁻⁸ C/m²

Explanation:

Given:

Radius of sphere (r) = 12 cm = 0.12 m

Distance from the electric field R = 24 cm = 0.24 m

Magnitude (E) = 640 N/C

Find:

Charge density on the sphere

Computation:

Charge on the sphere (q) = (1/K)ER²            (K = 9 × 10⁹)

Charge on the sphere (q) = [1/(9 × 10⁹)](640)(0.24)²

Charge on the sphere (q) = 4 × 10⁻⁹ C

Charge density on the sphere = q / [4πr²]

Charge density on the sphere = [4 × 10⁻⁹] / [4(3.14)(0.12)²]

Charge density on the sphere = [4 × 10⁻⁹] / [0.18]

Charge density on the sphere = 2.2 × 10⁻⁸ C/m²

A circuit consists of a coil that has a self-inductance equal to 4.3 mH and an internal resistance equal to 16 Ω, an ideal 9 V b
fredd [130]

Answer:

t = 186.2 μs

Explanation:

Current in LR series circuit

I(t) = I_{s}( 1 - e^{-Rt/L)}----(1)

steady current =  I_{s} = V/R

time constant = τ =L/R =4.3 * 10^{-3} / 16\\

                                              = 0.268 ms

magnetic energy stored in coil = U_{L} = \frac{1}{2}LI^{2}

rate at which magnetic energy stored in coil= \frac{d}{dt}U_{L} =\frac{d}{dt} \frac{1}{2}LI^{2}   \\                            = LI\frac{dI}{dt}\\----(2)

rate at which power is dissipated in R:

                                       P = I^{2}R---(3)

To find the time when the rate at which energy is dissipated in the coil equals the rate at which magnetic energy is stored in the coil equate (2) and (3)

I^{2}R=LI \frac{dI}{dt}

[/tex]I=\frac{L}{R}\frac{dI}{dt}[/tex]----(4)

differentiating (1) w.r.to t

I(t)=I_{f} (1-e^{\frac{Rt}{L} })

\frac{dI}{dt} = I_{f}\frac{d}{dt}(1-e^{\frac{-Rt}{L} }   )

\frac{dI}{dt}= I_{f}(-\frac{R}{L} e^{\frac{-Rt}{L} } )\\---(5)

substituting (5) in (4)

I=I_{f}e^{-\frac{Rt}{L} }----(6)

equating (1) and (6)

I_{f}( 1- e^{-\frac{Rt}{L} } ) = I_{f}e^{-\frac{Rt}{L} }

1 - e^{-\frac{Rt}{L} } =  e^{-\frac{Rt}{L} }

\frac{1}{2}= e^{-\frac{Rt}{L} }

t= -\frac{L}{R}ln\frac{1}{2}

L= 4.3 mH

R= 16 Ω

t = 186.2 μs

What is the acceleration of a 2000 kg truck that has an engine exert 400 N of<br> force?
amid [387]

The acceleration of a 2000 kg truck that has an engine exerts 400 N of force <u>at 0.2 m/s².</u>

<u />

Acceleration is the rate of change of the velocity of an item with appreciation to time. Accelerations are vector portions. The orientation of an item's acceleration is given by the orientation of the net pressure appearing on that object.

Calculation:-

mass = 2000 kg

Force = 400 N

acceleration = F/mass

                      =  400/2000

                      = <u>0.2 m/s²</u>

<u />

Acceleration is the charge at which velocity modifications with time, in terms of each speed and route. A factor or an object moving in a straight line is accelerated if it quickens or slows down. movement on a circle is extended despite the fact that the rate is consistent because the course is continually changing.
