From the experiment, we can be able to say that the animal learned from previous experience.

When we talk about learning, what we are talking about is the ability of a person to harness the past experiences and then bring it to bear on a current task. This means if an organism is said to be learning, then the organism that is in question would be able to gather the experiences of the past and then use it to make an intelligent decision in the future.

In this case, an animal was provided multiple strings, one of which would provide food when pulled. The animal pulled the strings until the food was obtained. This implies that the organism was able to learn from the variety of experiences that was provided to each by the pulling of the stings in the lever each time.

In a series circuit, there is only one path for the electricity to flow. This is because the circuit is made up of only one loop, and the electricity has to flow through all of the components in that loop.

The circuit is created by connecting the positive terminal of one component to the negative terminal of the next component, creating a loop. If any of the components in the circuit are not working, then the circuit is broken and the electricity will not flow. Circuit is created by connecting devices in a line, one after the other. This means that the current has to flow through each device in turn before it can reach the end of the circuit.

The acceleration of the object is obtained as  5 [tex]m/s^{2}[/tex]

The term acceleration has to do with the rate of change of the speed of an object with time. We know that the speed is the distance that is covered per unit time by the object.

In this case, we have the following information about the motion of the object;

Initial speed of the object = 0 m/s

Final speed of the object = 20 ms-1

Time taken for the change = 4 s

We gave to use the equation;

V = u + at

v = final velocity

u = initial velocity

a = acceleration

t = time

Then we substitute the values to get;

20 = 0 + 4t

Then we make the t the subject of this formula

t = 20/4

a) The magnitude of the impulse delivered to your roof is 1.13 × 10^-4 Kg m / s

b) The magnitude of the average force of the impact is 0.37 N.

a) Impulse is defined as the change in moment of object . The total impulse on an object is measured from the product mass of the object and the total change in velocity of the object. Impulse is a vector quentity so it has both magnitude as well as direction (negative or positive sign). Units of impluse in S.I system , Newton seconds, or N∗s.

Mathematically , J =m× v

v --> change in velocity which is equal to final velocity of object and substracting staring velocity.

m---> mass of object

We have, mass of raindrop (m) = 0.014 g = 0.014×10⁻³kg

the speed of raindrop (v) = 8.1 m/s

putting all values in above formula we get,

J = mv = 0.014×10⁻³ × 8.1 = 0.013 × 10⁻³ kg m/s

thus, value of impluse is 0.013×10⁻³3 kg m/s

b) Average force of impact is defind as the product of mass of object by the average velocity of object over a definite time.

According to Newton's Second law of motion,

force (F) = m× a

where m---> mass of object

a----> acceleration which is equal to change in velocity with respect to time.

Now, we have given m = 0.014 ×10⁻³3 kg

time = 0.37 ms

acceleration (a) = v/t = ( 8.1 m/s )/ 0.37 ms

putting all values in above formula we get,

force = (0.014×10⁻³kg × 8.1 m/s )/0.37 ×10⁻³ s

= 0.306N ~ 0.31N

Thus, magnitude of average force of impact is 0.31 N .

The position on the meter stick is 25 cm.

Solution:

The center of mass of the meter stick will be at 0.5 m and its torque about the pivot point will be T1 = mg(0.5 - 0.3)

T1 = 0.5*9.81*0.2 = 0.981 N-m (clockwise)

So we have to add 2 kg mass on the left side of the pivot so that it has a counter-clockwise torque about the pivot point.

Let us position it at x the its torque about pivot point will be T2 = mg(0.3 - x) = 2*9.81*(0.3 - x)

To support the stick T1 = T2

0.981 = 2*9.81*(0.3 - x)

0.3 - x = 0.05

x = 0.25 m = 25 cm.
