Answer: The potential energy associated with a mass attached to a spring depends on how much the spring is stretched or compressed. ... The gravitational force on the mass is −mg (“−” because the force points down). The force is the negative of the slope on the potential energy versus position graph.
Explanation:
:)
Its called condensation. condensation is <span>water that collects as droplets on a cold surface when humid air is in contact with it. aka. clouds</span>
Answer: a) 0.13*τ ; b) 2.08*τ
Explanation: In order to explain the discharg of a capacitor through a resistor, we have to consider the following:
Q(t)=Qo* exp(-t/τ) for a lose of 1/8-th of its charge
in this case, Q(t)=7/8*Qo=7/8*exp(-t/τ)
ln(7/8)*τ=-t
then, t= -ln(7/8)*τ =0.13
For a lose of 7/8 th of its charge , we have
Q(t)=1/7*Qo*exp(-t/τ)
t=-ln(1/8)*τ=2.08
Answer:
a)
b)
c) Therefore it is a nonconservative force
Explanation:
Distance traveled in one complete circular trip against friction
The force of friction is
The work of friction is the force of friction in the distance so
a).
b).
c).
Since the circle returns to its initial position in both cases and the work done by the friction force different in both cases, so the friction force does depend on the path;
Since the small body of water is connected to a larger body of water. so the small body of water will than be called a stream
