Answer:
a. You should use the thin cooking twine.
Explanation:
The velocity of wave on a rope is:
(1)
with T the tension and μ the linear density of the rope that is defined as , so (1) is:
with M the mass and L the length
Note that if L and T remain constant for bigger M velocity is going to be smaller and vice versa. So, we should chose the lighter rope that is the thin cooking twine to have the fastest wave speed.
Answer:
inhibitor
Explanation:
Inhibitors slow down chemical reactions. Inhibitors slow down or stop the activity of an enzyme.
Answer:
Let's say a horse. In it's environment biotic factors such as predators and other animals that the horse competes with for food are limiting factors. Abiotic factors are the amounts of water, the temperature, and precipitation are also limiting factors.
Answer: 1.76 s
Explanation:
We have the following data:
is the total mass of the bike and the rider
is the initial velocity
is the force applied to the brakes
Firstly, we will find the acceleration with the following equation:
(1)
Isolating :
(2)
(3)
(4) This is the magnitude of the acceleration, however, since the final velocity is 0 m/s, this means the direction is negative
Hence:
(5)
On the other hand, with the following equation we can find the time :
(6)
Where:
is the final velocity (the bike stops)
Isolating :
(7)
(8)
Finally:
This iste time it takes to the bike to stop
Answer:
created, destroyed, transforms
Explanation:
Energy cannot be created nor destroyed.
Energy is transformed from one form to another form.
- This is the postulate of the law of conservation of energy.
Energy is neither created nor destroyed simply implies that energy is not produce in any system. Nor is it destroyed.
What we have is energy transformation from one form to another.
