Answer:
a) p = m1 v1 + m2 v2
, b) dp / dt = m1 a1 + m2 a2
, c) It is equivalent to force
dp / dt = 0
Explanation:
In this problem we have two blocks and the system is formed by the two bodies.
Part A. Initially they ask us to find the moment of the whole system
p = m1 v1 + m2 v2
Part B.
Find the derivative
dp / dt = m1 dv1dt + m2 dv2 / dt
dp / dt = m1 a1 + m2 a2
Part C.
Let's analyze the dimensions
m a = [kg] [m / s2] = [N]
It is equivalent to force
Part d
Acceleration is due to a net force applied
Part e
The acceleration of block 1 is due to the force exerted by block 2 during the moment change
Part f
Force of block 1 on block 2
True f12 = m1a1 f21 = m2a2
Part g
By the law of action and reaction are equal magnitude F12 = f21
Part H
dp / dt = 0
Isolated system F12 = F21 and the masses are constant. The total moment is only redistributed
Answer:
The drift velocity is 
Explanation:
Given :
Area of metallic wire,
.
Current through wire , 
Mobile charge density , 
Charge value , 
We need to find drift velocity , 
Now, we know :

Therefore, 
Putting all given values in above equation we get,


Hence, this is the required solution.
It depends on chemistry... A physical deformation to the Jell-O.
Answer: Reflected
Explanation: Color Gradient refers to the variety of position dependent (as the vary with position) colors which are used to fill a region. Gradient is a mixture of two or more colors. This blend of colors adds depth to the design.
Types of color gradient are
- Linear: The color blends in a straight from starting to ending point
- Radial: The color transitions from starting point to ending a circular pattern.
- Angle: It glides counterclockwise around starting point.
- Diamond: It makes a diamond shape from starting point and its ending point is one corner of diamond.
- Reflected: In this color gradient type symmetric linear gradient gets mirrored on either side of the starting point. This type of color gradient can be used to depict a lead pipe.
1850 to 1900 because the slope would be 105. It says what is the greatest fall, so the upward slope of 120 wouldn't count.
