Explain how the meanings of the terms biotic factor and abiotic factor differ ?

Answers

Answer 1
Answer: Hi There!

Biotic factors are all the living things in an ecosystem, and abiotic factors are all of the non-living things in an ecosystem. So, they differ because they both mean opposite things.

Hope This Helps :)

When you ride a roller coaster that makes sharp turns ,you feel yourself being pushed to one side . Use Newton’s first law of motion to explain this phenomenon

Answers

Explanation:

Newton's first law says that an object in motion stays in motion, and an object at rest stays at rest, until acted upon by an unbalanced force.

When a roller coaster makes a sharp turn, your body continues going straight until the seat belt pushes you and changes your direction.  If the roller coaster didn't have seat belts, you'd slide off and continue moving straight.

A car traveling with constant speed travels 150 km in 7200 s. What is the speed of the car?Express the speed to two significant figures and include the appropriate units.

Answers

The speed of the car is 75 km/h

Further explanation

These are the formulas that we have to remember before solving the problem.

Speed is the rate of change of distance.

\large { \boxed {v = (d)/(t)}}

v = speed ( m/s )

d = distance ( m )

t = time ( s )

Acceleration is the rate of change of velocity.

\large { \boxed {a = (\Delta v)/(t)}}

a = acceleration ( m/s² )

Δv = change in speed ( m/s )

t = time ( s )

Let us now tackle the problem!

Given:

distance = d = 150 km

time taken = t = 7200 s = 2 hours

Unknown:

velocity = v = ?

Solution:

v = (d)/(t)

v = (150)/(2)

\large {\boxed {v = 75~km/h} }

The acceleration of the car is 0 m/s² because it travels with constant speed.

We could also plot the distance vs time graph as shown in the attachment.

Grade: Middle School

Subject: Physics

Chapter: Kinematics

Keywords: indycar top speed of a fastest police car has ever gone

Final answer:

The car's speed is 75 km/hour, as determined by dividing the total distance travelled (150 km) by the total time taken (2 hours).

Explanation:

To answer this question, we use the

formula for speed

, which is distance traveled divided by the time taken. Here, the distance travelled by the car is 150 km and the time taken is 7200 s (which is equal to 2 hours). Therefore, the speed will be 150 km divided by 2 hours, resulting in a speed of

75 km/hour

, stated to the correct number of significant figures.
