use the pendulum equation to calcuate the period of a 1.50 pendulum. Remeber that the vaule of "g" is 9.81 m/s² please help ​
kati45 [8]

Answer:

L = 3.51

Explanation:

Pendulum equation is T = 2pi\sqrt{L/9.81}

T = 1.5 and we are solving for L

1.5=2\pi \sqrt{L/9.81}

square both sides to get 2.25 = 2\pi ( L/9.81)

multiply both sides by 9.81 then divide by 2 and 3.14 as a substitue for pi. The answer should be about 3.51 in length

L = 3.51

A 6.0-kg box slides down an inclined plane that makes an angle of 39° with the horizontal. If the coefficient of kinetic frictio
jeka57 [31]

Answer:

a. 3.1 m/s^2

Explanation:

The equation of the forces along the directions parallel and perpendicular to the slope are:

- Along the parallel direction:

mg sin \theta - \mu_k R = ma

where :

m = 6.0 kg is the mass  of the box

g = 9.8 m/s^2 the acceleration of gravity

\theta=39^{\circ}  is the angle of the slope

\mu_k = 0.40 is the coefficient of friction

R is the normal reaction  

a is the acceleration

- Along the perpendicular direction:

R-mg cos \theta =0

From the 2nd equation, we get an expression for the reaction force:

R=mg cos \theta

And substituting into the 1st equation, we can find the acceleration:

mg sin \theta - \mu_k mg cos \theta = ma

Solving for a,

a=g sin \theta - \mu_k g cos \theta =(9.8)(sin 39^{\circ})-(0.40)(9.8)(cos 39^{\circ})=3.1 m/s^2

In your own words differentiate Comets Asteroids Meteors Meteoroids and Meteorites​
Eddi Din [679]

Thanks for the question,

Asteroids: These are rocky and airless plates from the formation of planets in our solar system. It basically revolves around our sun in the space barrier between Mars and Jupiter and moves in the size of cars to smaller planets.

Comets: comets are the most polluted glaciers of ice and dust created at the time of the birth of the solar system 4.6 billion years ago. Many comets have a fixed orbit around the outer surface of the solar system beyond the planet Neptune.

Meteoroids, Meteorites, Meteorites: Meteoroids are small asteroids or broken comet fragments and sometimes planets. They vary in size from sand dune to three large stones in diameter. When meteoroids collide with the earth's atmosphere, they form meteors. When those meteors survive space and reach the surface of the planet, their remains are called meteorites.
