Momentum before collision = momentum after collision
McVc=(Mc+Mb)V
1200*15.6=(1200+1500)*V
18720=2700*V
V=18720/2700
V=6.9m/s
Answer:
Explanation:
Statement 1 :
When the two different resistors are connected in parallel, then the current in both the resistors is different.
Yes, it is true, the voltage is same across both the resistors and then the current is different.
Statement 2 :
When the two different resistors connected in parallel, the voltage across each of them is different.
It is false, the voltage is same in both the resistors.
Statement 3 :
When three resistors are connected in parallel, the equivalent resistance is given by triple the resistance,
It is false, the equivalent resistance becomes one third of the individual resistance.
Answer:
3.78 kWh
Explanation:
Power of incandescent bulb = 60 W = 0.06 kW
Power of fluorescent bulb = 15 W = 0.015 kW
Number of hours in a week if each day the light is turned on 12 hours
12×7 = 84 hours
Difference in power
0.06-0.015 = 0.045 kW
Multiplying with the number of hours
Hence, the fluorescent bulb will consume 3.78 kWh less electricity energy than the incandescent bulb.
Answer:
Multiplexer
Explanation:
-In electronics, a multiplexer, also known as a data, is a device that selects between several analog or digital input signals and forwards it to a single output line.
-This device combines multiple circuits at one end of a connection into a single complex circuit on a single wire.
-The selected signals is then transmitted at a higher speed.
A caldera is a large cauldron-like depression that forms following the evacuation of a magma chamber or reservoir. When large volumes of magma are erupted over a short time, structural support for the crust above the magma chamber is lost, and the entire structure caves in and forms a large bowl-like shape.
