The car moves at 300 m/s on a highway, after 25s the car stops. What is acceleration?

Answers

Answer 1

Answer:

12

Explanation:

Acceleration=change in velocity/change in time

Change in velocity is 300-0 (because the car stops meaning velocity is 0) so the change is 300.

Change in time is 25-0(because time started at 0 secs.

300/25=12m/s^2

Sorry for the caps, I have been looking through answers and the answers never have 2 costs, only one.

Answers

Two costs:
• Tidal energy systems may alter wave currents and have a chance of being indirectly harmful for the environment; however the advantages would still arguably outweigh this
• Very expensive; for very many reasons, i’ll just list one on the top of my head. It’s still not a well established industry yet so resources and costs for these projects are very high demand (lack of mass production, etc.)

Explanation:

Astronauts need special tools to work in space. One specially designed tool that astronauts use is a screwdriver. Using Newton’s third law of motion, explain why it might be difficult to use a normal screwdriver to tighten a screw in space.

Answers

Due to the fact that for every action there is an equal reaction for every turn on the screw the screw will exert energy equal to the amount you gave

Astronauts need a specially designed tool that astronauts use as a screwdriver. Using Newton’s third law of motion, we can easily explain the fact of microgravity  in space that makes difficult to use a normal screwdriver to tighten a screw in space.

What is microgravity?

In a situation known as microgravity, persons or objects appear to be weightless. When astronauts and items float in space, one can observe the consequences of microgravity.

Unless acted upon by an imbalanced force, an object at rest will remain so, while an object in motion will maintain its speed. An object's propensity to resist changes in velocity, whether it's moving or not, is known as inertia.

In space compared to Earth, using a hand-held driver to spin a screw is a little trickier. On earth, gravity serves to secure a person's complete body to the surface. Turning a screw is a straightforward process. One uses one hand to turn the screw while standing on the ground.

Twisting a screw becomes difficult if one is free floating in a spaceship or space station cabin because, depending on the amount of friction present, it's possible that the person turning the screw is also turning themselves. That's why it might be difficult to use a normal screwdriver to tighten a screw in space.

Answer: tectonic plates

Explanation:

Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

An area with many volcanoes that includes the western borders of South, Central, and North America, the southern border of Alaska, and the eastern border of Japan is often called the Ring of Fire. Why did so many volcanoes form in these areas?

Answers

The volcanoes and earthquakes that are along the ring of fire are caused by the amount of movement of tectonic plates in the area. Plates overlap at convergent boundaries called subduction zones. As rock is subducted, it melts and becomes magma.
