Answer:
Part a)
v = 16.52 m/s
Part b)
v = 7.47 m/s
Explanation:
Part a)
(a) when the large-mass object is the one moving initially
So here we can use momentum conservation as the net force on the system of two masses will be zero
so here we can say
since this is a perfect inelastic collision so after collision both balls will move together with same speed
so here we can say
Part b)
(b) when the small-mass object is the one moving initially
here also we can use momentum conservation as the net force on the system of two masses will be zero
so here we can say
Again this is a perfect inelastic collision so after collision both balls will move together with same speed
so here we can say
Answer:
0N
Explanation:
Parameters given:
Q1 = Q2 = Q3 = 100 * 10^(-9) C
r = 0.3 m
The net force on the middle charge is:
F = F(1,2) + F(2,3)
Where F(1,2) = force due to Q1 on Q2
F(2,3) = force due to Q3 on Q2
F(1,2) = k*Q(1)*Q(2)/r²
F(1,2) = [9 * 10^9 * 100 * 10^(-9) * 100 * 10^(-9)]/(0.3²)
F(1,2) = 0.001N
F(2,3) = k*Q(2)*Q(3)/r²
F(2,3) = [9 * 10^9 * 100 * 10^(-9) * -100 * 10^(-9)]/(0.3²)
F(2,3) = -0.001N
Therefore,
F = 0.001 - 0.001
F = 0N
Answer:
Time = 0.187 secs
Explanation:
Parameters given:
Speed of hot air balloon = 1.60 m/s
Speed of toss = 10.7 m/s
Distance between passenger and friend at time of toss = 2m
To find the time given, we can simply divide the distance between the passenger and her friend by the speed of the toss. Mathematically,
Time = distance/speed
Time = 2/10.7
Time = 0.187 secs
Therefore, it takes 0.187 seconds for the camera to get to her.
A capacitor is connected to an ac supply. increasing the frequency of the supply increases the current through the capacitor
A capacitor is a device for storing electrical energy that consists of two insulated conductors in close proximity. The parallel-plate capacitor is a simple example of such a storage device.
A capacitor (also known as a condenser) is a two-terminal passive electrical component that stores energy electrostatically in an electric field. Practical capacitors come in a variety of shapes and sizes, but they all have at least two electrical conductors (plates) separated by a dielectric (i.e., insulator).
Capacitors exist in various shapes and sizes, and their value is measured in farads (F). Capacitors are utilized in both alternating current and direct current systems.
