Answer:
Completion between two organism is when they fight over resources inadvertently causing the use and destruction of recourses making it more scares. if they don't adapt they die out.
Start with an anecdote, surprising fact or quotes
The speed of a car travelling over a hill that has a radius of curvature should not exceed a certain speed other it will topple. This speed is related to the radius of curvature and the gravitational acceleration as shown below:
V^2 = Rg, where V = maximum speed, R = Radius of curvature, g = gravitational acceleration.
Substituting;
V = Sqrt (Rg) = Sqrt (120*9.81) = 34.31 m/s
Answer:
Jupiter's gravitational acceleration is 24.8 m/s^2
Explanation:
Recall that the weight under the influence of a gravitational acceleration G is defined as:
Weight = m * G
Then, in our case we have
372 N = 15 kg * G
G = 372/15 m/s^2
G = 24.8 m/s^2
Answer:
<h3>
The coefficient of kinetic friction between the puck and the ice is
0.12</h3>
Explanation:
Given :
Initial speed 
Displacement
m
From the kinematics equation,

Where
final velocity, in our example it is zero (
),
acceleration.


From the formula of friction,

Minus sign represent friction is oppose the motion
Where
( normal reaction force )
( ∵
)
So coefficient of friction,


Therefore, the coefficient of kinetic friction between the puck and the ice is
0.12 .
