Answer:
The system's kinetic energy changes by 3.6 J
Explanation:
The given parameters are;
The number of cart = 2
The mass of each cart = 0.5kg
The initial length of the spring = 0.50 m
The final length of the spring =T0.3 m
The change in position of the first cart = 0.6 m
The energy given to the first cart = Work done by the force = Force × Displacement
The initial kinetic energy of the two cart moving together = Energy given to the first cart = 6.0 × 0.2 = 1.2J
The kinetic energy given to the two cart combined = The applied force × The total displacement of the two cart as they move together
The kinetic energy given to the two cart combined = 6.0 × (0.6 - 0.2)
The kinetic energy given to the two cart combined = 6.0 × 0.4 = 2.4 J
The total kinetic energy given to the two cart = 1.2 + 2.4 = 3.6 J
The total kinetic energy given to the two cart = 3.6 J
The system's kinetic energy changes by 3.6 J.
The point on a line through the ends of the meter stick is the electric field equal to zero is 4.7 m from the 0 cm mark.
<h3>What is electric field?</h3>
An electric field is the physical field that surrounds the electrically charged particles and exerts force on all other charged particles in the field, either attracting or repelling them. It also refers to physical field for a system of charged particles. Electric fields originate from the electric charges and time-varying electric currents. Electric fields and the magnetic fields are both manifestations of the electromagnetic field, one of the four fundamental interactions (also called forces) of nature.
Electric fields are important in many areas of the physics, and are exploited in electrical technology. In atomic physics and chemistry, for the instance, the electric field is the attractive force holding the atomic nucleus and electrons together in atoms. It is also force responsible for chemical bonding between atoms that result in molecules.
The electric field is defined as a vector field that associates to each point in the space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point. The derived SI unit for electric field is the volt per meter (V/m), which is equal to the newton per coulomb (N/C)

The correct question will be:
"A +5.00-μC point charge is placed at 0.0 cm mark of meter stick and a -4.00-μC point charge is placed at 50.0 cm mark. At what point on a line through the ends of meter stick is electric field equal to zero?"
Answer:
The gauge pressure in Pascals inside a honey droplet is 416 Pa
Explanation:
Given;
diameter of the honey droplet, D = 0.1 cm
radius of the honey droplet, R = 0.05 cm = 0.0005 m
surface tension of honey, γ = 0.052 N/m
Apply Laplace's law for a spherical membrane with two surfaces
Gauge pressure = P₁ - P₀ = 2 (2γ / r)
Where;
P₀ is the atmospheric pressure
Gauge pressure = 4γ / r
Gauge pressure = 4 (0.052) / (0.0005)
Gauge pressure = 416 Pa
Therefore, the gauge pressure in Pascals inside a honey droplet is 416 Pa
