Answer:

The inner planets are smaller and rockier

Explanation:

Astronomers divide the planets into two groups in Solar system, the inner planets and outer planets. The inner planets are smaller and rockier and it is closer to the sun. The outer planets are larger , further far away and made of gas

The inner planets are Mercury, Venus , Earth and Mars. The outer planets Jupiter , Saturn , Uranus and Neptune comes after an asteroid belt. In some other planetary systems the gas are close to the sun.

particles in a disk of gas and dust will form Planets. If they orbit the star they are colliding and sticking. The stars wind blows away their gases . So the nearest planets to starts are rockier.

Experts, ACE, Genius... can anybody calculate for the Reactions at supports A and B please? Will give brainliest! Given: fb = 30

dybincka [34]

Answer:

Support at Cy = 1.3 x 10³ k-N

Support at Ay = 200 k-N

Explanation:

given:

fb = 300 k-N/m

fc = 100 k-N/m

D = 300 k-N

L ab = 6 m

L bc = 6 m

L cd = 6 m

To get the reaction A or C.

take summation of moment either A or C.

<em><u>Support Cy:</u></em>

∑ M at Ay = 0

(( x1 * F ) + ( D * Lab ) + ( D * L bc + D * L cd )

Cy = -------------------------------------------------------------------

( L ab + L bc )

Cy = 1.3 x 10³ k-N

<em><u>Support Ay:</u></em>

Since ∑ F = 0, A + C - F - D = 0

A = F + D - C

Ay = 200 k-N

a roller coaster begins at the top of a hill if it acelerates at the rate of 2 m/s2 and has a mass of 2000 kg what net force is

AlladinOne [14]

Answer:

$\boxed {\boxed {\sf 4000 \ Newtons }}$

Explanation:

Force can be found by multiplying the mass by the acceleration.

$F=m*a$

The mass of the roller coaster is 2000 kilograms and the acceleration is 2 meters per second squared.

$m= 2000 \ kg \\a= 2 \ m/s^2$

Substitute the values into the formula.

$F= 2000 \ kg * 2 \ m/s^2$

Multiply.

$F= 4000 \ kg*m/s^2$

1 kg*m/s² is equal to 1 N
Therefore our answer of 4000 kg*m/s² is equal to 4000 Newtons

$F= 4000 \ N$

The net force acting on the roller coaster is <u>4000 Newtons.</u>
