Incomplete question as we have not told to find what.So the complete question is here
A vessel at rest at the origin of an xy coordinate system explodes into three pieces. Just after the explosion, one piece, of mass m, moves with velocity (-60 m/s)i and a second piece, also of mass m, moves with velocity (-60 m/s)j. The third piece has mass 3m.Just after the explosion, what are the (a) magnitude and (b) direction of the velocity of the third piece?
Answer:
Explanation:
Given data
The vessel at rest
Piece one,of mass m,moves with velocity=(-60 m/s)i
Piece two,of mass m,moves with velocity=(-60 m/s)j
Piece three,of mass 3m
As the linear momentum is conserved in this system,Because the system is closed and no external force acting on it
So momentum is given as
As the vessel at rest so the initial momentum is zero
So
The power generated by the students will be .
•Work done is equal to
Mgh = 90*9.8*1.5
1587.6 j
thus power is equal to work done by time
1587.6/3
529.2 j/secs

The interpretation including its given subject is listed in the subsection below on explanatory.
Explanation:
Homeostasis should be any mechanism of self-regulation from which an individual seeks to preserve equilibrium when adapting to requirements better suited towards its existence.
<u>Two mechanisms are given below:</u>
- Blood Pressure: Pressure is regulated by either a homeostatic system through which the blood becomes circulated throughout the individual's body.
- Body Temperature: The body requires multiple forms of heat regulatory oversight such as:
- Endothermic is something a living creature can hold one's own internal body temperature.
- Ectothermic is really where the external atmosphere absorbs temperature.
Answer:
Physics is important in our daily life because it deals with daily objects we need like light, electricty and sound. Without physics, we cant have the ability to see because lights wont be a thing, we cant use phones, cars and such because they wont work without electricty, you wont be able to listen to your favourite band without sound!
Answer:
<em>tenis</em>
Tenis applies to each of Newton's 3 Laws of Motion because with the first law if a tenis ball is at rest it will stay at rest unless acted on by an unbalanced force which would be playing tenis in which it would stay in motion. The second law applies since the acceleration at which it is hit times the mass equals the force it has. The third law applies since when hitting a tenis ball back and forth with racquets the reaction may be equal or opposite
