V1 = 0.60 m3, P1 = 5.00atm, T1=400K
V2 = ??m3, P2 = 4.00atm, T2=200K
P1V1/T1 = P2V2/T2
V2 = T2P1V1/T1P2 = 200×5×0.60/400×4.00 = 600/1600
V2 = 0.38 m3

A boy rows a rowboat across a river. The boat moves at 4.3 m/s at a direction of 25°

NikAS [45]

East component: 3.9 m/s

South component: 1.8 m/s

Explanation:

We have to resolve the velocity vector along the east and south axis.

Taking east as positive x-direction and south as positive y-direction, the components of the velocity are given by:

$v_x = v cos \theta\\v_y = v sin \theta$

where

v = 4.3 m/s is the magnitude of the velocity

$\theta=25^{\circ}$ is the angle between the direction of the velocity and of the x-axis

Substituting into the equations, we find:

East component:

$v_x = (4.3)(cos 25^{\circ})=3.9 m/s$

South component:

$v_y = (4.3)(sin 25^{\circ})=1.8 m/s$

A certain dam generates 120 MJ of mechanical (hydroelectric) energy each minute. If the conversion from mechanical to electrical

Karolina [17]

Answer:

electric energy ( power ) = 300000 W

Explanation:

given data

mechanical (hydroelectric) energy = 120 MJ/min = 2000000 J/s

efficiency = 15 % = 0.15

solution

we know that Efficiency of electric engine is expression as

Efficiency = Mechanical energy ÷ electric energy ......................1

and here dam electrical power output is

put here value in equation 1

electric energy ( power ) = Efficiency × Mechanical energy ( power )

electric energy ( power ) = 0.15 × 2000000 J/s

electric energy ( power ) = 300000 W

For small angles, does the pendulum's period of oscillation depend on initial angular displacement from equilibrium? Explain.

aksik [14]

Answer:

No, the pendulum's period of oscillation does not depend on initial angular displacement.

Explanation:

Given that,

For small angle, the pendulum's period of oscillation depend on initial angular displacement from equilibrium.

We know that,

The time period of pendulum is defined as

$T=2\pi\sqrt{\dfrac{l}{g}}$

Where, l = length of pendulum

g = acceleration due to gravity

So, The time period of pendulum depends on the length of pendulum and acceleration due to gravity.

It does not depend on the initial angular displacement.

Hence, No, the pendulum's period of oscillation does not depend on initial angular displacement.
