Explanation:
1. if an object sjnks in one liquid and floats on another liquid it implies that the density of second liquid is greater than the density of first liquid
Answer:
Explanation:
(newtons first law)
conservation of momentum law states :
momentum before collision = momentum after collision
momentum p (kg-m/s)= mass * velocity
say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s
say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s
total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s
momentum after collision = 10 000 kg-m/s
mass now = 1 000 kg+2 000 kg = 3 000 kg
10 000 = 3 000 kg* velocity m/s
10 000/3 000 = velocity
3.33 m/s = velocity after collision
an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
Answer:
PLS MARK ME AS BRAINLIEST
Explanation:
The need for reference of reliable scholarly source in academic writing (i.e. project) is to provide guide needed to confirm the writing of the scholar and to ascertain the writing are clear of plagiarism.
In academic writing, writers are required to state out the list of sources of information because:
1)To confirm authenticity of the writing
2)To prevent future plagiarism claim from the scholar.
3)To provide guide on how to trace the scholar writing
4)To complete the requirement of good academics writing
In conclusion, providing reliable scholarly source is the backbone of writing a perfect academics article, journal inclusive.
As you illustrate the problem, you may come up with the same diagram as the one shown in the attached picture. The relative velocity is the linear velocity between the two velocities. This is calculated by simply finding the difference of their velocities. Since, the velocity is with respect to Jane relative to Mary, the solution is as follows:
Relative velocity = Velocity of Jane - Velocity of Mary
Relative Velocity = 4.67 m/s - 3.59 m/s =
1.08 m/s
Stars burn by fusing hydrogen into helium. The process can be observed as if hydrogen is a fuel for the star. Thanks to the process, the stars release heat and light. When there's no more hydrogen, the star starts to grow smaller while its heat increases. Eventually, the star dies.
