The compound limestone (which is mined in Crossville) is chemically
Salsk061 [2.6K]

Answer:

True

Explanation:

Limestone is a carbonate chemical sedimentary rock often chemically called calcium carbonate.

The mineral calcium carbonate makes up the framework of this rock that has become the staple material used for cement production.

Chemically, the formula is given as CaCO₃. The rock accumulates from the a rich deposit of calcite, which is the mineral that is made up of calcium carbonate to form the limestone.

          CaCO₃         -        Calcite      -        Limestone

     compound                mineral                   rock

Limestone is a rock and the compound it is made up of is calcium carbonate. In some cases, a Ca-Mg carbonate occurs with limestone and it is called a dolomite.

A puck sliding on ice approaches a 20 degrees ramp at 10 m/s with coefficient of friction 0.2. How high will it go up the ramp a
timama [110]

Answer:

it will go up along the inclined plane by d = 9.62 m

Explanation:

As we know that puck is moving upward along the slide

then the net force opposite to its speed is given as

F_{net} = - mgsin\theta - \mu mgcos\theta

so here deceleration is given as

a = -g(sin\theta + \mu cos\theta)

now plug in all values in it

a = -9.81(sin20 + 0.2cos20)

a = -5.2 m/s^2

now the distance covered by the puck along the plane is given as

v_f^2 - v_i^2 = 2 a d

0 - 10^2 = 2(-5.2)d

d = 9.62 m
