Power = (voltage) x (current)
13 watts = (6 volts) x (current)
Divide each side by (6 volts):
Current = (13 watts) / (6 volts)
Current = (13/6) Amperes
<em>Current = 2.17 Amperes</em>
Answer:
Mechanical energy, U = 0.247 Joules
Explanation:
Given that,
Spring constant of the spring, k = 234 N/m
Mass, m = 524 g = 0.524 kg
Amplitude, A = 4.6 cm = 0.046 m
To find,
The mechanical energy of the system.
Solution,
We know that the sum of kinetic energy and the potential energy is equal to its mechanical energy. In mass-spring system, it is given by :
U = 0.247 Joules
So, the mechanical energy of the system is 0.247 Joules.
Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature.
Answer:
The answer to your question is: C. -9.81 m/s²
Explanation:
A. 9.81 m/s² acceleration is considered positive when it goes to the center of the earth, so this option is incorrect.
B. 0 m/s² This option is incorrect because acceleration is 0 for a linear motion without acceleration.
C. -9.81 m/s² If a projectile goes to the sky, then the acceleration will be negative.
D. It is not constant. Acceleration is constant.
Answer:
the red at the bottom should not count, but the red at the top is the least dense because it floats upon the other liquids
