A mass of 2 kg stretches a spring 4 cm. There is no external force and the mass moves in a medium that impacts a viscous force o

f 2 N when the speed of the mass is 2 cm/s. If the mass is set in motion from position 1 cm below equilibrium with an initial velocity of 3 cm/s formulate the initial value problem for the motion of the mass x(t). Determine the frequency, period, amplitude, and phase of the motion.

Can you explain what a mixture is from a chemical prospective?
sergeinik [125]

Answer:

Mixtures are materials that contain two or more chemical substances dispersed among each other (mixed together). If no chemical reaction occurs when two materials are mixed, they form a mixture. The chemical properties of the components don't change.

aev [14]

Answer:

where the y axis is

Explanation:

In more simple terms, a horizontal line on any chart is where the y-axis values are equal. If it has been drawn to show a series of highs in the data, a data point moving above the horizontal line would indicate a rise in the y-axis value over recent values in the data sample.

A conducting sphere contains positive charge distributed uniformly over its surface. Which statements about the potential due to
stira [4]

Answer:

a. FALSE

b. FALSE

c. TRUTH

d. FALSE

e. FALSE

Explanation:

To determine which statements are truth or false you focus in the following formula, for the electric potential generated by a conducting sphere:

V=\frac{Q}{4\pi \epsilon_o R}      inside the sphere

V'=\frac{Q}{4\pi \epsilon_o r}      for r > R (outside the sphere)

R: radius of the sphere

ε0: dielectric permittivity of vacuum

Q: charge of the sphere

As you can notice, inside the sphere the potential is constant. Inside the sphere, the potential is the same. Outside the surface the potential decreases as 1/r, being r the distance to the center of the sphere.

Hence, you can conclude:

a. The potential at the center of the sphere is zero. FALSE

b.The potential is lowest, but not zero, at the center of the sphere. FALSE

c. The potential at the center of the sphere is the same as the potential at the surface. TRUTH

d. The potential at the center is the same as the potential at infinity. FALSE

e. The potential at the surface is higher than the potential at the center. FALSE
