What does displacement depend on

What is the name of the theory describing how the lithosphere is broken into segments, or plates, which "float" on the asthenosp

kogti [31]

Answer:

C. Plate Tectonics

Explanation:

The theory of plate tectonics is when the lithosphere is separated into plates. These plates move over or float over the asthenosphere. The movement of these plates cause earthquakes and can interact with the volcanic activity.

Is the refraction different entering medium that has a higher index of refraction compared to entering amedium that has a lower

oee [108]

Answer:

Yes

Explanation:

The speed of light when it travels through glass, diamond, etc, the light travels at different speed from the speed of light. Speed of the light in material is related to the index of refraction.

The change in speed which occurs when the light passes from one medium to the another is responsible for bending of the light which is called as refraction.

<u>When the light goes into a medium with the higher index of the refraction, light bends towards normal. Conversely, if the light traveling goes from higher refractive index to lower refractive index, it will bend away from the normal. </u>

<u>Hence, the refraction is different in both the scenario.</u>

two vehicles have a head on collision. one vehicle has a mass of 3000 kg and moves at 25 m/s while the second vehicle has a mass

emmasim [6.3K]

Answer:

The speed of the combined vehicles is 6.82m/s

Explanation:

Using the law of conservation of momentum which stayed that the sum of momentum of bodies before collision is equal to their sum of momentum after collision. After collision, both object moves with the same velocity.

Momentum = mass×velocity

Before collision:

Momentum of vehicle or mass 3000kg moving with velocity 25m/s

= 3000×25

= 75000kgm/s

Pa = 75000kgm/s

Momentum of vehicle with mass 2500kg moving with velocity of -15m/s

= 2500×-15

= -37500kgm/s

After collision:

Momentum = (3000+2500)V

Where v is their common velocity

Momentum after collision = 5500V

Based on the law:

75000+(-37500) = 5500V

75000-37500 = 5500V

37500 = 5500V

V = 37500/5500

V = 6.82m/s

4720 kj of energy are supplied to a material in order to raise its temperature by 65k. if the specific heat capacity of the mate

jeka57 [31]

The mass of material is 26.6 Kg

Given:

Q = 4720 KJ

Change in Temperature (AT) = 65 K

Specific heat capacity of material (c) = 2730 J K Kg*K

The relation between Q, AT, c and m are related by following formula: Q=m* c*∆T,

Plugging value in heat formula:

4720KJ = m* 2730 J/Kg*K * 65K

4720KJ = m * 177450J/kg

Converting 177450 J/kg to Kg/KJ

177450 J/kg*1KJ/1000J = 177.450KJ/kg

Dividing both side by 177.450KJ/kg

4720KJ/177.450KJ/Kg = m*177.450KJ/Kg÷ 177.450KJ/Kg

Hence, the mass of material = 26.6 Kg
