Radiant energy is the energy of electromagnetic and gravitational radiation
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.
At the tip of either of the magnets poles
A recurring illness. Typically lasts for a very long time and are very hard to remove.
Answer:
Linear mass density,
Explanation:
Given that,
Mass of the string, m = 0.3 g = 0.0003 kg
Length of the string, l = 1.5 m
The linear mass density of a string is defined as the mass of the string per unit length. Mathematically, it is given by :
or
So, the linear mass density of a string is 
. Hence, this is the required solution.
