Answer:

1. From top to bottom and then back to top

2. From bottom to top and then back to bottom

Explanation:

As Time Period or periodic time period is time it takes to complete one complete cycle. So only these two options are correct. Yes ! If you assume a frictionless and isolated system then these two time intervals must be equal.

The mass then moves up and down between the "top" and the "bottom" positions. By definition, the period of such motion is the time interval it takes the mass to move<em> from the top position to the bottom and then back to the top</em>, <u>OR</u><em> from the bottom position to the top and then back to the bottom</em>.  The time for these two motions are nominally equal.

____ [38]

Tension may be defined as the pulling power transferred axially through a cable, string, chain, or alike one-dimensional unceasing object, or by separately end of a rod.

To compute for tension:

Sum the moments about the pivot: 


ΣM = 0 = T * 3.5m * sin37 º - 45000N * 7.0m * cos37º 
tension T = 119 434 N

A rope is attached to a block. The rope pulls on the block with a force of 240 N, at an angle of 40 degrees to the horizontal (t
Tom [10]

Answer:

X Component is 183.85N

Explanation:

The x component of the force on the block due to the rope;

X = F cos @ where if is the force, @ is the angle mad with the block.

X = F cos @

X = 240 cos 40

Cos 40= 0.7660, so

X = 240 × 0.7660

X component= 183.85N// rounded to two decimal places.

A solid, uniform disk of mass M and radius a may be rotated about an axis parallel to the disk axis, at variable distances from
cricket20 [7]

Answer:

the function varies linearly with the radius of the disk, so the smallest period is zero for a radius of zero centimeters

Explanation:

This system performs a simple harmonic movement where the angular velocity is given by

         w = √ k / I

Where k is the constant recovered from the axis of rotation and I is the moment of inertia of the disk

The expression for the moment of inertia is

           I = 1/2 m r²

Angular velocity, frequency and period are related

         w = 2π f = 2π / T

Substituting

             2π / T = √ k / I

             T = 2π √ I / k

             T = 2π √ (½ m r² / k)

             T = (2π √m / 2k)   r

 

We can see that the function varies linearly with the radius of the disk, so the smallest period is zero for a radius of zero centimeters

A proposed space elevator would consist of a cable stretching from the earth's surface to a satellite, orbiting far in space, th
NISA [10]

To solve this problem we will apply the concepts related to energy conservation. Here we will use the conservation between the potential gravitational energy and the kinetic energy to determine the velocity of this escape. The gravitational potential energy can be expressed as,

PE= \frac{GMm}{d}

The kinetic energy can be written as,

KE= \frac{1}{2} mv^2

Where,

G = 6.67*10^{-11}m^3/kg\cdot s^2Gravitational Universal Constant

m = 5.972*10^{24}kg Mass of Earth

h = 56*10^6m  Height

r = 6.378*10^6m Radius of Earth

From the conservation of energy:

\frac{1}{2} mv^2 = \frac{GMm}{d}

Rearranging to find the velocity,

v = \sqrt{\frac{2Gm}{d}} \rightarrow  Escape velocity at a certain height from the earth

If the height of the satellite from the earth is h, then the total distance would be the radius of the earth and the eight,

d = r+h

v = \sqrt{\frac{2Gm}{r+h}}

Replacing the values we have that

v = \frac{2(6.67*10^{-11})(5.972*10^{24})}{6.378*10^6+56*10^6}

v = 3.6km/s

Therefore the escape velocity is 3.6km/s

Two blocks, 1 and 2, are connected by a rope R1 of negligible mass. A second rope R2, also of negligible mass, is tied to block
alekssr [168]

Answer:

Explanation:

Given

Two block are connected by rope R_1

R_2 rope is attached to block 2

suppose F_2 is a force applied to Rope R_2

Applied force F_2=Tension in Rope 2

F_2=(m_1+m_2)a---1

where a=acceleration of system

Tension in rope R_1 is denoted by F_1

F_1=m_1a---2

divide 1 and 2 we get

\frac{F_2}{F_1}=\frac{(m_1+m_2)a}{m_1a}

also m_1=2.11\cdot m_2

\frac{F_2}{F_1}=\frac{2.11m_2+m_2}{2.11m_2}

\frac{F_2}{F_1}=\frac{3.11}{2.11}

\frac{F_1}{F_2}=\frac{2.11}{3.11}
