Current = (voltage) / (resistance)

= 60v / 12 ohms

= 5 Amperes.

A spring with a mass of 1 kg has a spring constant 43 kg/s2. If the spring begins at equilibrium position and is given a velocit
Alexxandr [17]

Answer:

Damping constant is equal to 2\sqrt{43}

Explanation:

We have given mass m = 1 kg

Spring constant is given k=43kg/sec^2

For critical damping \zeta =1

We have to find the damping constant

Damping constant is equal to \zeta =\frac{c}{2\sqrt{\frac{k}{m}}}

So 1 =\frac{c}{2\sqrt{\frac{k}{m}}}

c=2\sqrt{\frac{k}{m}}

=2\sqrt{\frac{43}{1}}=2\sqrt{43}

So damping constant is equal to 2\sqrt{43}

HELP ASAP!!!!!!!!!<br><br><br> What is the difference between a contact force and a distance force?
Karo-lina-s [1.5K]
A contact force are forces that require actual contact (touch) of two pieces of matter.

Distant force is a force that works at a distance not needing any contact (touch) at all.

The moon Umbriel orbits Uranus (mass = 8.68 x 10^25 kg) at a distance of 2.66 x 10^8 m. What is Umbriel's orbital period (in hou
Whitepunk [10]

Answer:

T = 99.51 hour

Explanation:

Mass of Uranus, M=8.68\times 10^{25}\ kg

The moon Umbriel orbits Uranus at a distance of 2.66\times 10^8\ m

We need to find Umbriel's orbital period. Let it is T. Using Kepler's third law of motion to find it.

T^2\propto r^3\\\\T^2=\dfrac{4\pi^2r^3}{GM}\\\\T^2=\dfrac{4\pi^2\times (2.66\times 10^8)^3}{6.67\times 10^{-11}\times 8.68\times 10^{25}}\\\\T=358244.51\ s

As 1 hour = 3600 s

358244.51 s = 99.51 hour

Hence, Umbriel's orbital period is 99.51 hour.

What is the kinetic energy of a 0.150 kg<br> object moving at a velocity of 100m/s?
ozzi

Answer:

750J

Explanation:

Given parameters:

Mass of the object   = 0.15kg

Velocity of the object  = 100m/s

Unknown:

Kinetic energy of the body  = ?

Solution:

The kinetic energy is the energy due to the motion of a body. It is mathematically expressed as;

        K.E  = \frac{1}{2} m v²  

m is the mass of the body

v is the velocity

 Now insert the parameters and solve;

     K.E  = \frac{1}{2}  x 0.15 x 100²   = 750J
