Answer:
the difference in the amount of energy that charge carriers have between two points in a circuit
Explanation:
Answer:
3.32 m/s
Explanation:
From the law of conservation of energy, the sum of mechanical and kinetic energy should be equal to the 10 J given. Potential energy is given by mgh where m is mass, g is acceleration due to gravity and h is the height. For this case, and l is string length, given as 2 m, \theta is given as 50 degrees. Kinetic energy is given by and it is this velocity that is unknown.
Answer:
Explanation:
spring constant k = 425 N/m
a ) At the point of equilibrium
restoring force = frictional force
= kx = 10 N
425 x = 10
x = 2.35 cm
b )
Work done by frictional force
= -10 x 2.35 x 10⁻² x 2 J ( Distance is twice of 2.35 cm )
= - 0.47 J
= Kinetic energy remaining with the cookie as it slides back through the position where the spring is unstretched .
= 425 - 0.47
= 424.53 J
=
A model train traveling at a constant speed around a circular track has a constant velocity. FALSE.
Hope this helps you!
I believe the answer is B. let me know If I was right.
