Answer:
There are 5 general layers; organism, population, community, ecosystem, and biosphere.
Explanation:
Hope this helps!
Average speed = total distance / total time
= (81 + 88) / (2 + 2)
= 169/4
= 42.25 kilometers/hour
Let me know if you have any questions.
Because the box keeps going straight at the same speed, while the seat under it speeds up, slows down, or changes direction.
As per Newton's II law we know that

here F = force applied
m = mass of object = 2 kg
a = acceleration = 2 m/s^2
now as per above formula we will have


so here applied force on the ball will be 4 N
Answer:
We conclude that the force on the bag is 500 N.
Explanation:
Given
- Acceleration a = 0.5 m/s²
To determine
Force F = ?
We know that when a force is applied to a body, it produces acceleration.
<u>Important Tip: </u>
- We can determine the force on the bag using the formula F = ma
Using the formula

where
is the force
is the mass
is the acceleration
now substitute m = 1000, and a = 0.5 m/s² in the formula


N
Therefore, we conclude that the force on the bag is 500 N.
