Here we have mass that moves at ceratin speed. This means that we have momentum. The law that must be observed is law of conservation of momentum. It states that momentum before certain event is equal to a momentum after that event. Here we have three masses so we can write this as:

Before the firecracker blows a coconut does not move, so left side is equal to 0:

We know that m1=m2=m and m3=2m. Also we are asked to find v3f so we can rewrite formula:

We must take in consideration that two parts with same mass do not move in same direction. The center of mass of these two parts moves between them at angle of 45° with respect to both south and west. The speed of a center of mass is:

This speed we can insert into formula for v3f:

We can see that part of a coconut with biggest mass has same speed as center of mass of two other parts. Negative sign shows that direction is opposite to direction of two pats. Biggest part moves towards north-east.
Answer:
To create an electric potential difference between the ends of the conductor.
Explanation:
For current to flow, there must exist an electric potential difference between the ends of the conductor. This PD is provided by the electromotive force stored within the battery. Unless there is a connection between the terminals no PD will exist between the terminals.
Answer:
phytochemical
Explanation:phytochemical is a tool for studying motion
Answer:
The answer is: c.) Both students get the same time constant, since the time constant does not depend on the charge on the capacitor
Explanation:
Both students, because the time constant is not dependent on the capacitor charge. We can express the equation of the time constant as follows:
Time constant = RC
In this equation it is observed that the time constant is equal to the multiplication of the resistance (R) multiplied by the capacitance (C)
I think the answer is solar wind and I not it’s meteors
