Your friend is on rollerblades holding a pendulum. You gently push her forward and let go. You observe that the pendulum first s

wings in the opposite direction (backward) and then returns to the vertical orientation as she coasts forward.
Part A
Choose the correct force diagram of the pendulum bob (in inertial reference flame) as your friend is being pushed. y-direction is the vertical direction.

It would be using Newton's First Law. Newton's First Law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. It may be seen as a statement about inertia, that objects will remain in their state of motion unless a force acts to change the motion.

About how much energy is transferred between a producer and primary consumer?
Elza [17]

Answer

Correct Answer is C (10% of the plant's energy is transferred

Explanation:

Ecosystem

ecosystem is a community where large number of  living organisms lives. These living organism are plants, trees, different types of animals, birds etc. These living organism depends on each other for their food.

Their are various levels in ecosystem like producer, primary consumer, secondary consumer and tertiary consumer.

producer like plants produce their food on their own. And primary consumers takes their food from producers.

According to 10% Rule of ecology only 10% energy is passed from one level to another.So 10% of the plant's energy is transferred

Why is it important for the path of a circuit to be circular?
vredina [299]

Answer:

When the platform rotates, the rotating mass will travel in a circular path due to the force exerted on it by the string (by way of the tension in the spring). Since it is not possible to have an instantaneous readout of this tension force while the platform is rotating, an indirect measurement of this force will be made using the weight of the static mass as shown and explained below.

Which wave, A or B, has lower energy? A, because it has a higher amplitude B, because it has a higher amplitude A, because it ha
frutty [35]

Energy of wave depends on its amplitude and it is given as

E = \frac{1}{2} kA^2

here k = constant

A = amplitude

so energy will increase or decrease depends on the amplitude of the wave

So here if we need to check which wave has lower energy then we need to compare the amplitude.

If the amplitude is less then energy must be less

So please check in the figure that which wave out of A and B has lesser amplitude to find out the wave of lesser energy
