Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.
Answer:
0.384c
Explanation:
To find the speed of the pursuit ship relative to the cruiser you use the following relativistic equation:
u': relative speed
u: speed of the pursuit ship = 0.8c
v: speed of the cruiser = 0.6c
c: speed of light
You replace the values of the parameters to obtain u':
Hence, the relative speed is 0.384c
Answer:
eukaryote
Explanation:
made up of prokaryote xells
The distance the object willl fall durring the 2nd seconds is 4.9 m
<h3>Data obtained from the question</h3>
The following data were obtained from the question:
- Initial velocity (u) = 0 m/s
- Acceleration due to gravity (g) = 9.8 m/s²
- Time (t) = 2 - 1 = 1 s
- Height (h) =?
<h3>How to determine the distance the object will fall during the 2nd seconds</h3>
The distance the object will fall during the 2nd seconds can be obtained as follow:
h = ut + ½gt²
h = (0 × 1) + (½ × 9.8 × 1²)
h = 0 + 4.9
h = 4.9 s
Thus, the distance the object will during the 2nd seconds is 4.9 m

Utilizing the momentum principle is a good strategy since there are no outside forces acting on system, its total linear momentum is constant, and the total beginning and final momentum of the system are equal.
<h3>What does momentum mean in the real world?</h3>
The amount that motion is referred to as momentum. Since an object possesses speed if it is moving and has mass, amount is measurable in this situation. An object doesn't have momentum if it isn't moving. Nevertheless, despite its significance in everyday life, many people remained unaware of it.
<h3>What use does momentum serve?</h3>
Momentum is a vectors quantity since it has both size and direction. Since inertia has a direction, it is used to forecast the direction and rate of motion of objects after a collision. Below is a one-dimensional description of the fundamental characteristics of momentum.
