Answer:

Answer:

- creation of mid-ocean ridges

-creation of new mountains

-formation of earthquakes

-formation of volcanoes

Convergent boundary plate tectonic involves collisions between oceanic and  continental plates. The thinner and less denser oceanic plate overriden by the thicker and more denser continental plate. The oceanic plate is forced down the mantle, this event is known as subduction. The magma present in the mantle causes melting of subduction plates. The magma enters inside these plates through pores. This magma plate becomes bouyant and moves upwards. The molten magma causes volcanic eruptions along with earthquakes. If the magma solidifies in the subduction zone it creates mid ocean ridges. The mountains are formed near the continents when the magma after volcanic eruption gets cooled and solidified.

Answer 2
Answer:

All the events are associated with convergent boundaries. Creation of mid-ocean ridges, Creation of new mountains, and formation of earthquakes.

What are convergent boundaries?

A convergent boundary occurs when two or more lithospheric plates clash on Earth. Subduction is the process through which one plate moves beneath the other.

The events are associated with convergent boundaries are;

1 . Creation of mid-ocean ridges

2. Creation of new mountains

3. Formation of earthquakes

4. Formation of volcanoes

Collisions between oceanic and continental plates are involved in convergent boundary plate tectonics. The oceanic plate, which is thinner and less dense, is pushed aside by the continental plate,

Which is thicker and denser. Subduction occurs when an oceanic plate is driven down into the mantle. The melting of subduction plates is caused by magma in the mantle.

The magma seeps into the pores of these plates. This magma plate rises as it gets buoyant. Volcanic eruptions and earthquakes are both caused by molten magma.

Mid-ocean ridges form as magma solidifies in the subduction zone. Mountains are generated near continents as lava cools and solidifies following a volcanic eruption.

13)Brittany is changing the tire of her car on a steep hill of height =H= 20.0 m 

She trips and drops the spare tire of mass = m = 10.0 kg, 

The tire rolls down the hill with an intial speed = u = 2.00 m/s. 

The height of top of the next hill = h = 5.00 m 

Initial total mechanical energy =PE+KE=mgH+(1/2)mu^2 

Initial total mechanical energy =mgH+(1/2)mu^2 

Suppose the final speed at the top of second hill is v 

Final total mechanical energy =PE+KE=mgh+(1/2)mv^2 

As mechanical energy is conserved, 

Final total mechanical energy =Initial total mechanical energy 

mgh+(1/2)mv^2=mgH+(1/2)mu^2 

v = sq rt [u^2+2g(H-h)] 

v = sq rt [4+2*9.8(20-5)] 

v = sq rt 298 

v =17.2627 m/s 

The speed of the tire at the top of the next hill is 17.2627 m/s

1.) A train is accelerating at a rate = a = 2.0 km/hr/s. 

Acceleration 

Initial velocity = u = 20 km/hr, 

Velocity after 30 seconds = v = u + at 

Velocity after 30 seconds = v = 20 km/hr + 2 (km/hr/s)*30s = 

Velocity after 30 seconds = v = 20 km/hr + 60 km/hr = 80 km/ hr 

Velocity after 30 seconds = v = 80 km/hr=22.22 m/s

What is the difference between the way matter responds to a transverse wave and a longitudinal wave?A. Matter moves in the same direction in a longitudinal wave, and at right angles to the direction of a transverse wave.
B. Matter moves at right angles to the direction of a longitudinal wave, and at right angles to the direction of a transverse wave.
C. A longitudinal wave does not need matter through which to travel, while a transverse wave does.
D. A longitudinal wave needs matter through which to travel, while a transverse wave does not.

Answers

Answer:

B

Explanation:

Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.

Acceleration of gravity is proportional to  1/D² .
('D' is the distance from the Earth's center.)

We need  (D / R)² = 9.8
('R' is the Earth's radius.)

D/R = √9.8 = 3.13

Distance from Earth's center = 3.13 R
Distance above Earth's surface = 2.13 R = about 13,570 km =====================================================

Accelerarea de gravitate este proporțională cu 1 / D².
('D este distanța de centrul Pământului.)

Avem nevoie de (D / R) ² = 9,8
('R' este raza Pământului.)


D / R = √9.8 = 3,13

Distanța de la centrul Pamantului = 3,13 R
Distanța de deasupra suprafetei Pamantului = 2.13 R = aproximativ 13,570 km

How can one object affect the motion of another without touching it? Give a specific example.

Answers

There are two types of forces

1. Physical force : in this type of forces we require direct contact between two bodies

2. Field force: here we do not requires any type of physical contact with the body

so here in this type of field force we do not required any contact but only due to field present near it the body can move

so here several examples are there

a) when a magnet is placed near a piece of iron then it will move towards the iron

b) a positively charged particle when come near another charged particle then it will get attracted or repelled.

so as per all above discussion we can say that an object can move without any direct contact

Final answer:

Objects can affect the motion of others without touching through the force of gravity. For example, the Moon affects the tides on Earth.

Explanation:

One way that an object can affect the motion of another without touching it is through the force of gravity. Gravity is a long-range force that acts between all objects with mass. For example, the Moon affects the motion of the tides on Earth without physically touching the water.
