A rock with no grains or a glass-like texture is formed in what environment?

Physics
1 answer:
Nuetrik [128]3 years ago
3 0

The correct answer is - water environment.

When a rock doesn't have any grains, or has a glass-like texture, than it means that that rock has been formed with very extreme and quick cooling. This kind of cooling is possible only in the water environment. Once the lava gets in touch with the water, it starts to cool off very quickly, and in a very short span of time an igneous rock is formed, but unlike most of the igneous rocks, this rocks will lack grains, or will have the glassy appearance because they didn't had enough time to form any grains.

Answer:

Tangential velocity = 10.9 m/S

Explanation:

As per the data given in the question,

Force = 20 N

Time = 1.2 S

Length = 16.5 cm

Radius = 33.0 cm

Moment of inertia = 1200 kg.cm^2 = 1200 × 10^(-4) kg.m^2

= 1200 × 10^(-2) m^2

Revolution of the pedal ÷ revolution of wheel = 1

Torque on the pedal = Force × Length

= 20 × 16.5 10^(-2)

= 3.30 N m

So, Angular acceleration = Torque ÷ Moment of inertia

= 3.30 ÷ 12 × 10^(-2)

= 27.50 rad ÷ S^2

Since wheel started rotating from rest, so initial angular velocity = 0 rad/S

Now, Angular velocity = Initial angular velocity + Angular Acceleration × Time

= 0 + 27.50 × 1.2

= 33 rad/S

Hence, Tangential velocity = Angular velocity × Radius

= 33 × 33 × 10^(-2)

= 10.9 m/S

tresset_1 [31]

Answer:

Ver explicación

Explanation:

Según los principios de Arquímedes, el empuje hacia arriba de un objeto sumergido en un fluido es igual al peso del fluido desplazado.

Por eso

Empuje hacia arriba = volumen del objeto * densidad del fluido * aceleración debida a la gravedad

Empuje hacia arriba = 2 * 10 ^ -6 / 2 * 1 * 10 ^ 3 * 10

Empuje hacia arriba = 0.01 N

Desde;

Empuje hacia arriba = peso del fluido desplazado

peso del fluido desplazado = 0.01 N

Masa de fluido desplazado = 0.01 N / 10 = 1 * 10 ^ -3 Kg o 1 g
