Answer:
The speed of water ripples, v = 0.15 m/s
Explanation:
It is given that,
Water ripples are produced by making a cork oscillate up and down at a frequency of 5 Hz, f = 5 Hz
The peaks of the ripples are 0.03 meters apart,
We need to find the speed of the water ripples. The speed of water ripple is given by :
v = 0.15 m/s
So, the speed of water ripples is 0.15 m/s. Hence, this is the required solution.
Answer:
c)
Explanation:
As we know that resultant force is the net force that is acting on the system
As per Newton's II law we know that net force is product of mass and acceleration
so we will have
here we know
m = 80 kg
for circular motion acceleration is given as
now we have
Answer:
a. Capacitance
b. Charge on the plates
e. Energy stored in the capacitor
Explanation:
Let A be the area of the capacitor plate
The capacitance of a capacitor is given as;
where;
V is the potential difference between the plates
The charge on the plates is given as;
The energy stored in the capacitor is given as;
Thus, the physical variables listed that will change include;
a. Capacitance
b. Charge on the plates
e. Energy stored in the capacitor
