Answer:
impulse acting on it
Explanation:
The impulse is defined as the product between the force applied to an object (F) and the time interval during which the force is applied (
):
We can prove that this is equal to the change in momentum of the object. In fact, change in momentum is given by:
where m is the mass and 
is the change in velocity. Multiplying and dividing by , we get
and since 
is equal to the acceleration, a, we have
And since the product (ma) is equal to the force, we have
which corresponds to the impulse.
Mv + mv = 2mv providing each momentum is in the same direction.
1/2 mv^2 + 1/2 mv^2 = mv^2
Hi there!
II. Linear momentum of the system is zero.
This is an example of a RECOIL collision. With the Law of Conservation of Momentum, momentum remains constant before and after the collision.
Thus, the total momentum would also be equivalent to zero after the collision.
Answer:
This values shows a right angle triangle
Explanation:
Given;
a vector 4.0 km due East
a 3.0 km due north
the resultant vector is 5.0 km
The resultant vector can be obtained by Pythagoras theorem if the vectors form a right angle triangle.
R² = 4² + 3²
R² = 16 + 9
R² = 25
R = √25
R = 5 km (right angle triangle proved)
Therefore, this values shows a right angle triangle
Answer: If it has ions, it is an electrolyte
Explanation:
Let's start by explaining that electrolytes are compounds that contain charged particles or<u> ions</u>, which can be cations (positive ions) or anions (negative ions).
So, it is this composition that makes an electrolytic material conduct electricity.
In this sense, the way to identify if a material is an electrolyte or not, is knowing whether it is composed of ions or not.
