I am Pushing down at a 20

At the presentation ceremony, a championship bowler is presented a 1.64-kg trophy which he holds at arm's length, a distance of

Grace [21]

To solve the problem it is necessary to take into account the concepts of the kinetic equations for the description of the torque at the rate of force and distance.

By definition the torque is given by,

$\tau = F*d$

where,

$F= Force$

$d = Distance$

For the problem in question the mass of the trophy is 1.64Kg and the distance of the tropeo to the board (the shoulder) is 0.655m

PART A) For part A, the torque with the given mass and the stipulated torque in the horizontal plane must be calculated as well,

$\tau = F*d$

For Newton's second law

$\tau = mg*d$

$\tau = 1.64*9.81*0.655$

$\tau = 10.5Nm$

PART B) For part B there is an angle of 26 degrees with respect to the horizontal, therefore to know the net torque it is necessary to know the horizontal component to the formed angle, that is,

$\tau = F*dcos\theta$

$\tau = mgdcos\theta$

$\tau = 1.64*9.81*0.655*cos26$

$\tau = 9.471Nm$

What do comets and asteroids have in common? Check all that apply.

Sidana [21]

Answer:

- They are orbiting the Sun

- They are small compared to the planets

Explanation:

- Comets are small bodies made of rock and ice that have a highly elliptical orbit, and that warm when they pass close to the Sun, releasing gas due to the sublimation of the ice, producing a characteristic "tail" that can extend even for hundreds of kilometers. They are generally located outside the Solar System, in the Oort cloud.

- Asteroids are irregular bodies whose size range from a few km to even a few hundreds of km, that orbit the Sun in an area of the Solar System located between Mars and Jupiter, called "Asteroid belt". They are made mainly of rock and metal debris

So now we can analyze the statements given:

- They are made of ice: FALSE, because this is only valid for comets

- They are orbiting the Sun: TRUE for both comets and asteroids

- They are made of metal debris: FALSE, this is only valid for asteroids

- They are small compared to the planets: TRUE for both (the biggest asteroid, Ceres, has a radius of approx 500 km, much smaller than the smallest planet, Mercury)

- They are at the center of the solar system: FALSE for both
