Answer:

In many vibrating systems the frictional force Ff can be modeled as being proportional to the velocity v of the object: Ff = −cv, where c is called the viscous damping coefficient.

A 1.25 kg block is attached to a spring with spring constant 17.0 N/m . While the block is sitting at rest, a student hits it wi

Free_Kalibri [48]

Answer:

The amplitude of the subsequent oscillations is 13.3 cm

Explanation:

Given;

mass of the block, m = 1.25 kg

spring constant, k = 17 N/m

speed of the block, v = 49 cm/s = 0.49 m/s

To determine the amplitude of the oscillation.

Apply the principle of conservation of energy;

maximum kinetic energy of the stone when hit = maximum potential energy of spring when displaced

$K.E_{max} = U_{max}\\\\\frac{1}{2} mv^2 = \frac{1}{2} kA^2\\\\where;\\\\A \ is \ the \ maximum \ displacement = amplitude \\\\mv^2 = kA^2\\\\A^2 = \frac{mv^2}{k} \\\\A = \sqrt{\frac{mv^2}{k}} \\\\A = \sqrt{\frac{1.25\ \times \ 0.49^2}{17}} \\\\A = 0.133 \ m\\\\A = 13.3 \ cm$

Therefore, the amplitude of the subsequent oscillations is 13.3 cm

Two satellites orbit the Earth in circular orbits of the same radius. One satellite is twice as massive as the other. Which stat

loris [4]

To solve this problem it is necessary to apply the concepts related to the orbital velocity of a satellite on earth.

This concept is expressed in the equation,

$v = \sqrt{\frac{Gm_E}{r}}$

Where,

G = Universal Gravitational constant

$m_E =$ Mass of the Earth

Therefore the ratio of the velocity from two satellites is,

$\frac{v_1}{v_2} = \sqrt{\frac{r_2}{r_1}}$

The ratio between the two satellites is the same, then

$\frac{v_1}{v_2} = \sqrt{\frac{r}{r}}$

$\frac{v_1}{v_2} = 1$

$v_1 =v_2$

Therefore the correct option is B.

MrMuchimi

<span>example shows that electromagnetic waves can travel without moving through a specific material is
</span>light passing through a vacuum tube
because it shows that there is no medium
so correct option from above is D
hope it helps
