Calcular la velocidad tangencial y la velocidad angular de un movil que describe una circunferencia de 18 centimetros de radio e
Hoochie [10]

Answer:

1.41 m/s, 7.85 rad/s

Explanation:

We can start by calculating the tangential velocity, which is given by:

v=\frac{2\pi r}{T}

where

r = 18 cm = 0.18 m is the radius of the circumference

T = 0.8 s is the period

Substituting,

v=\frac{2\pi(0.18)}{0.8}=1.41 m/s

Now we can also calculate the angular velocity,  which is given by:

\omega=\frac{2\pi}{T}

where again,

T = 0.8 s is the period

Substituting,

\omega=\frac{2\pi}{0.8}=7.85 rad/s

A spring with a spring constant of 165 N/m is attached to a 2.0 kg mass and set into motion.
marin [14]

Explanation:

We have,

Spring constant of the spring, k = 165 N/m

Mass, m = 2 kg

It is required to find the period of the mass-spring system. For the spring mass system, the period is given by :

T=2\pi \sqrt{\dfrac{m}{k} }\\\\T=2\pi \sqrt{\dfrac{2}{165} }\\\\T=0.69\ s

The frequency of vibration is reciprocal of its time period. So,

f=\dfrac{1}{T}\\\\f=\dfrac{1}{0.69}\\\\f=1.44\ Hz

So, the period of the mass-spring system is 0.69 s and frequency is 1.44 Hz.

When comparing saturated and naturally occurring unsaturated fats, the unsaturated fats have __________ and are __________ at ro
Len [333]

Answer: have "cis C=C double bonds" and "liquid" at room temperature.

Explanation:

The unsaturated fatty acids have one or more C=C double bonds in the cis formation. Thus, this results in the molecules not been as stable as the saturated fats. They have weaker intermolecular bonds thus resulting in lower melting point . The consequently results in it being liquid at room temperature.
