Answer:
<h2>2.10 meters per second</h2><h2 />
Explanation:
speed (velocity) = distance / time
= <u>0.2 km (1000 m/km) </u>
95 secs.
= 2.10 meters per second
If i am reading this question right the answer should be the south pole
Answer:
Explanation:
Consider downward displacement first .
downward displacement h = 38 m .
downward acceleration = g
downward initial velocity u = 0
h = ut + 1/2 g t ²
38 = 0 + 9.8 t ²
t = 1.97 s
During this period , there will be horizontal displacement with initial velocity u = 10 m /s and acceleration a = 1.6 m /s²
s = ut + 1/2 a t²
= 10 x 1.97 + .5 x 1.6 x 1.97²
= 19.7 + 3.10
= 22.8 m
Answer:
1. Decrease
2. Decrease
3. Stay the same
Explanation:
1. The more predators there are that eat the prey(cricket/frog), the less prey there will be.
2. The more the pollution effects them negatively, the more the population will die off.
3. The decrease of food may kill the population, but the increase of food does not effect the birth rate of the population.
Answer:
What is a Free Body Diagram?
The free body diagram helps you understand and solve static and dynamic problem involving forces. It is a diagram including all forces acting on a given object without the other object in the system. You need to first understand all the forces acting on the object and then represent these force by arrows in the direction of the force to be drawn.
