Answer:
1.2kV
Explanation:
We are given that
Linear charge density,
We have to find the potential difference between poinst 5.0 m and 6.0 m from the wire.
We know that potential difference of wire
Where
Substitute the values
1kV=1000 V
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.
Answer:
look it up im not a sheaperd sorry
Explanation:
Answer:Stars are born within the clouds of dust and scattered throughout most galaxies.It's the star Sirius in the constellation Canis Major, brightest star in the sky. The bright planet Venus is also up before dawn now. But you'll know Sirius, because Orion's Belt always points to it.With an apparent magnitude of −1.46
Explanation: Brainliest Please!!!!
Answer:
5000 N/m
Explanation:
Hooke's law for the spring is
where here we have
F = 100 N is the force applied to the spring
k is the spring constant
is the stretching of the spring with respect to its equilibrium position
Solving the equation for k, we find the spring constant:
