If two objects of the same size move through the air at different speeds, which encounters the greater air resistance?a. The fas
blagie [28]

Answer:

Option A is correct.

(The faster object encounters more resistance)

Explanation:

Option A is correct. (The faster object encounters more resistance)

Air resistance depends on various factors:

  • Speed of the object
  • Cross-sectional area of the object
  • Shape of the object

Formula:

F=\frac{1}{2}C_d\rho A v^{2}

As the speed of the object increases the amount of Air resistance/drag increases on the object, as the above formula shows direct relation between Air resistance/drag and velocity i.e F ∝ v^2.

an oscillator with a mass of 310 g and a period of 0.180 s has amplited that decreases by 20 % during each complete oscillation
Alex

Answer:

1.241/s

Explanation:

From this question, we have the following information:

Mass of oscillator = 310

The time Period, t = 0.180

Decrease = 20 %

Amplitude of oscillation has the formula

A = Aoe^yt

1-20% = 80%

= 0.80

Y x 0.18 = -ln(0.8)

= 0.18Y = 0.2234

Y = 0.2233/0.18

Y = 1.241/s

The damping constant y is Therefore equal to 1.241s

A rock is dropped from a distance RE above the surface of the earth, and is observed to have kinetic energy K1 when it hits the
goblinko [34]

Answer:

\dfrac{K_2}{K_1}=\dfrac{4}{3}

Explanation:

When an object strikes the ground, the potential energy of the rock gets converted to the kinetic energy.

A rock is dropped from a distance R_e above the surface of the earth and is observed to have kinetic energy K_1 when it hits the ground.

For another rock, It is dropped from twice the height 2R_e above the earth’s surface and has kinetic energy K_2 when it hits.              

For the first rock, K_1=GMm(\dfrac{1}{R_e}-\dfrac{1}{2R_e})=\dfrac{GMm}{2R_e}..............(1)

For the second rock, K_2=GMm(\dfrac{1}{R_e}-\dfrac{1}{3R_e})=\dfrac{2GMm}{3R_e}..............(2)

Dividing equation (2) by (1) we get :

\dfrac{K_2}{K_1}=\dfrac{4}{3}

Hence, this is the required solution.
