*I will be using “a” for acceleration, “V” for velocity and “t” for time

Acceleration is the change in velocity over a specific period of time. In our situation, that time is 10 seconds, as the velocity went from 15m/s to 0m/s in seconds. If we say that the formula for acceleration is:

a = V2-V1/t (where V2 is the final velocity, or 0m/s, and V1 the inital, or 15m/s)

We can plug in the numbers:

a = (0-15)m/s / 10s
a = -15m/s / 10s
a = -1.5m/s^2 — we notice here that the acceleration is negative, and thats because the car is decelerating (slowing down). If the car was accelerating, or speeding up, the acceleration would be positive.

Rocks will eventually come from other rocks as described by the rock cycle. Given this, what do you think is the type of the old
RoseWind [281]

Answer:

The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another. The rock cycle by definition is a natural process by which sedimentary, igneous, and metamorphic rocks are created, changed from one type to another, and destroyed.

The Sedimentary Rocks is the type of the oldest rocks on Earth.

Sedimentary rocks, such as sandstone, are created by the compression of sediment or particles. ... The oldest whole rocks found so far date back about 4.28 billion years. They were found in 2001 by geologists excavating near Canada's Hudson Bay in northern Quebec, andthe research appeared in the Sept.

When a ray is incident upon a plane mirror as shown in the diagram, what is the angle of refraction?
Anna11 [10]

Answer:

0 degrees

Explanation:

this is because when the light ray hits a surface a medium at 90 degrees then the angle of incidence = 0 , thus light doesn't bend when it enters the medium, no bending means angle of refraction is 0 degrees

hope this helps ,please mark it
