Answer:
Explanation:
The photons travel faster faster through space because photons always travel through space faster than electrons, in fact when an electron gets hitted by a photon this boost its speed
Physics is a branch of science that deals with the properties of matter and energy and relationship between them it also tries to explain the material world of the natural phenomenon of the universe the scope of physics is very wide and vast
Answer:
The situation where a seafloor plate slides under a continental plate during subduction is best described by convergent plate boundary.
Explanation:
The earth’s crust is broken down into tectonic plates that can move independently. They can interact in three different ways: converge (move toward one another), diverge (move away from one another) or transform (slide past one another). The three kinds of plate margins (boundaries where plates meet) are oceanic-oceanic, continental-continental, and continental-oceanic.
The regions where the plates are moving towards one another are known as convergent plate boundaries. During the convergence of continental and oceanic plates, the more-dense oceanic plate sinks below the less-dense continental plate and the oceanic plate is forced down further into the mantle. This is known as subduction. When the plate enters the mantle, the inside pressure breaks the rock. The broken rocks begins to melt from the heat due to the friction and as a result magma is formed. This magma rises toward the surface by breaking through the crust and forms a chain of volcanoes known as a volcanic arc such as the Cascade Mountains of North America and the Andes Mountains of South America.
During the convergence of two oceanic plates, one of the plates sinks underneath the other and forms an ocean trench (deep depression). The plate that sinks further down into the mantle starts to melt and as a result magma rises toward the surface and forms a chain of volcanic islands behind the ocean trench.
During the convergence of two continental plates, they buckle and compress to form complex mountains ranges of great height such as the Himalayas.
Answer:
3 m/s²
Explanation:
Sum of forces in the x direction:
∑F = ma
68 N − 23 N = (15 kg) a
a = 3 m/s²
a)The average acceleration of the car is
b) The distance travelled is 560 m
<u>Explanation:
</u>
a) Acceleration is defined as the rate of change in velocity per unit time. So it can be obtained by measuring the ratio of speed to time.
Since here the initial speed was zero and final speed is given as 28 m/s, then time is given as 20 s. So,
b) As the speed is given as 28 m/s, then
So the distance travelled is 560 m and average acceleration is .
