The entangled velocity of the cars after the collision is 2.7 m/s.
<h3>What is velocity?</h3>
Velocity is the rate of change of displacement. The S.I unit of velocity is m/s.
To calculate the velocity of the entangled cars after the collision, we use the formula below.
Formula:
- mu+MU = V(m+M).............. Equation 1
Where:
- m = mass of the car
- M = mass of the truck
- u = initial velocity of the car
- U = initial velocity of the truck.
- V = velocity of the entangled car after the collision.
Make V the subject of the equation.
- V = (mu+MU)/(m+M)............ Equation 2
From the question,
Given:
- m = 2000 kg
- M = 18000 kg
- u = 0 m/s (at rest)
- U = 3 m/s
Substitute these values into equation 2
- V = [(2000×0)+(18000×3)]/(2000+18000)
- V = 54000/20000
- V = 2.7 m/s.
Hence, the entangled velocity of the cars after the collision is 2.7 m/s

B.) Carbon Dioxide because the carbon is surrounded by oxygen
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.
Hello.
The answer is: D. weak nuclear force.
The weak force causes beta decay, a form of radioactivity. It could not be explained by the strong nuclear force, the force that’s responsible for holding the atomic nucleus together, because this force doesn’t affect electrons.
It couldn’t be the electromagnetic force, because this does not affect neutrons, and the force of gravity is far too weak to be responsible.
Have a nice day
A cyclist must lean into a turn to prevent tipping over in the other direction.The frictional force provides the centripetal force necessary to turn the cyclist to the left.But the frictional force also produces a clockwise torque that will cause the rider and the bicycle to tip clockwise to the right.The force is provided by the friction of the tires.
