The type of function that describes the amplitude of damped oscillatory motion is _______. The type of function that describes t

Salsk061 [2.6K]

Answer:

exponential

Explanation:

type of function that describes the amplitude of damped oscillatory motion is exponential because as we know that here function is

y = A × $e^{\frac{-bt}{2m}}$ × cos(ωt + ∅ ) ..................................... ( 1 )

here function A × $e^{\frac{-bt}{2m}}$ is amplitude

as per equation ( 1 )it is exponential

so that we can say that amplitude of damped oscillatory motion is exponential

Consider a metal single crystal oriented such that the normal to the slip plane and the slip directions are at angles of 43.1° a

Bond [772]

Answer:

resolve shear stress = 22 MPa

Explanation:

Given data

slip plane α = 43.1°

slip directions β = 47.9°

shear stress = 20.7 MPa (3,000 psi)

applied stress =45 mPa (6,500 psi)

to find out

what stress will be necessary

solution

we know that

resolve shear stress = aplied stress × cosα × cosβ

resolve shear stress = 45 × cos(43.1) × cos(47.9)

resolve shear stress = 22 MPa

we can say that here single cristal will be yield

because resolve shear stress is bigger than critical shear stress

The acceleration of gravity on the moon is about 1.6 m/sec 2. An experiment to test gravity compares the time it takes objects t

Valentin [98]

The answer is b. 6.1 times as long

Step 1: Calculate the time it takes objects to reach a speed on the Moon.
Step 2: Calculate the time it takes objects to reach a speed on the Earth.
Step 3. Divide the time on the Moon by the time on the Earth.

Use the formula: v2 = v1 + at
v2 - the final velocity
v1 - the initial velocity
a - gravitational acceleration
t - time

Step 1.
Moon:
v1 = 0 (because it is free fall)
v2 = 10 m/s
a = 1.6 m/s²
t = ?
______
v2 = v1 + at
10 = 0 + 1.6t
10 = 1.6t
t = 10/1.6
t = 6.25 s

Step 2.
Earth:
v1 = 0 (because it is free fall)
v2 = 10 m/s
a = 9.81 m/s²
t = ?
______
v2 = v1 + at
10 = 0 + 9.81t
10 = 9.81t
t = 10/9.81
t = 1.02 s

Step 3:
6.25 s / 1.02 s = 6.1 s

A 86 kg human stands on the surface of Venus. The mass of Venus is 4.9 × 1024 kg and its radius is 6.1 × 106 m. Collapse questio

iris [78.8K]

Answer:

755.37 N

Explanation:

We are given that

Mass of venus= $m_1=4.9\times 10^{24}kg$

Radius= $r=6.1\times 10^6$ m

Mass of human= $m_2=86 kg$

We know that the gravitational force between two bodies

$F=G\frac{m_1m_2}{r^2}$

Where G=Gravitational constant= $6.67\times 10^{-11}Nm^2/kg^2$

Using the formula

The magnitude of the gravitational force exerted by Venus on the human= $F=\frac{6.67\times 10^{-11}\times 86\times 4.9\times 10^{24}}{(6.1\times 10^6)^2}$

The magnitude of the gravitational force exerted by Venus on the human=F= $755.37N$
