If im correct you just add them together? so it might just be 1500 km west cause they are traveling in the same direction. i could be wrong but hope this helps.
Answer:
The speed of the 270g cart after the collision is 0.68m/s
Explanation:
Mass of air track cart (m1) = 320g
Initial velocity (u1) = 1.25m/s
Mass of stationary cart (m2) = 270g
Velocity after collision (V) = m1u1/(m1+m2) = 320×1.25/(320+270) = 400/590 = 0.68m/s
Yes! a new substance is formed when you observe a chemical property.
A chemical property changes the identity of the original item. Such as rust forming on an iron nail from oxygen reaction.
<span> Chemical properties are those that have the faculty to change the nature of the substance, i.e. to transform the substance (element or compound) into a different substance.
For example, Metals have the property to combine with oxygen to produce the metallic oxide.
This property drives to the change of the metal into a new product (with different composition, different bonds, different molar mass, etc). </span>
Answer:
The force that must be exerted on the pen is 0.0804 N.
Explanation:
Given;
pressure applied on a piece of paper by ball point of the pen, P = 0.067 N/mm²
surface area of the pen ball point, A = 1.2 mm²
The force that must be exerted on the pen is calculated as;
F = P x A
F = (0.067 N/mm²) x (1.2 mm²)
F = 0.0804 N
Therefore, the force that must be exerted on the pen is 0.0804 N.
