The momentum of the red cart before the collision is 0.2 kgm/s and the blue cart is 0.
The momentum of the red cart after the collision is 0.05 kgm/s and the blue cart is 0.15 kgm/s.
The change in momentum of the system of the carts is 0.
<h3>
Initial momentum of the carts before collision</h3>
The momentum of the carts before the collision is calculated as follows;
P(red) = 0.5 kg x 0.4 m/s = 0.2 kgm/s
P(blue) = 1.5 x 0 = 0
<h3>Momentum of the carts after collision</h3>
The momentum of the carts after the collision is calculated as follows;
P(red) = 0.5 x 0.1 = 0.05 kgm/s
P(blue) = 1.5 0.1 = 0.15 kgm/s
<h3>Change in momentum of the carts</h3>
ΔP = (0.05 + 0.15) - (0.2)
ΔP = 0

Answer:
The correct answer to the question is
a. a compound that conducts electricity when molten
Explanation:
A molecular is solid comprises of a collection of molecules combined together by van der Waals forces and not having covalent or ionic bonds. They are made up of forces atoms or molecules combined by dipole-dipole forces, London dispersion forces or hydrogen bonds. Exmples include graphite and diamonds. The forces between the molecules in molecular solid is also known as intermolecular forces (IMFs)

The length of the string is 
The angular velocity is 
The tension on the string is 
Generally the centripetal force acting on the rock is mathematically evaluated as
making m the subject of the formula
substituting values
Answer:
The baseball was falling during 1.733 seconds.
Explanation:
The baseball experimented a free fall, which is a particular case of uniformly accelerated motion, in which object is accelerated by gravity. In this case, we need to determine the time spent by the ball before hitting the ground (
), measured in seconds, which is determined by the following kinematic formula:
(1)
Where:
, 
- Initial and final speeds of the baseball, measured in meters per second.
- Gravitational acceleration, measured in meters per square second.
If we know that 
, 
and 
, then the time spent by the baseball is:
The baseball was falling during 1.733 seconds.
