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 spherical object (with non-uniform density) of mass 16 kg and radius 0.22 m rolls along a horizontal surface at a constant lin
Lapatulllka [165]

Answer:

Kr = 0.7618K

Explanation:

Suppose that the object's velocity is V, then his kinetic energy is:

K = \frac{mv^{2} }{2}

K = \frac{(16)v^{2} }{2}

K = 8v^{2}

The rotational kinetic energy is

Kr = \frac{Iw^{2} }{2}

           where I: The moment of inertia

                      ω: angular velocity

Kr =\frac{(0.59)w^{2} }{2}

Kr = 0.295w^{2}

How the movement is without slipping, then  

ω = \frac{v}{r}

ω = \frac{v}{0.22}

Thus

Kr = \frac{0.295v^{2} }{0.22^{2} }

Kr = 6.095v^{2}

8v^{2}  ---->  1

6.095v^{2}----->?

Kr = 0.7618K

A parallel plate capacitor is created by placing two large square conducting plates of length and width 0.1m facing each other,
borishaifa [10]

Answer:

8.854 pF

Explanation:

side of plate = 0.1 m ,

d = 1 cm = 0.01 m,

V = 5 kV = 5000 V

V' = 1 kV = 1000 V

Let K be the dielectric constant.

So, V' = V / K

K = V / V' = 5000 / 1000 = 5

C = ε0 A / d = 8.854 x 10^-12 x 0.1 x 0.1 / 0.01 = 8.854 x 10^-12 F

C = 8.854 pF
