density of water = 
velocity of flow = 
radius of pipe = 
Height of second floor = 
Now we can use here Bernuoli's Equation to find the speed of water flow at second floor
Now in order to find the radius of pipe we can use equation of continuity
So radius of pipe at second floor is 0.034 meter
Answer:
The cable run exceeds the specifications for Ethernet over twisted pair
Explanation:
The ethernet network's router also serves as a bridge to the Internet. The router connects to the modem, which carries the Internet signal, sending and receiving data packet requests and routing them to the proper computers on the network.
Ethernet is a way of connecting computers together in a local area network or LAN. It has been the most widely used method of linking computers together in LAN s since the 1990 s.
The basic idea of its design is that multiple computers have access to it and can send data at any time.
Answer:
Explanation:
No of atoms of Ra in 1 g of sample = 6.023 x 10²³ / 226
N = 2.66 x 10²¹
disintegration constant λ = .693 / half life
half life = 1620 x 365 x 60 x 60 x 24 = 5.1 x 10¹⁰ s
disintegration constant λ = .693 / 5.1 x 10¹⁰
radioactivity dn / dt = λN
= (.693 / 5.1 x 10¹⁰ ) x 2.66 x 10²¹
= .3614 x 10¹¹ per sec
= 3.614 x 10¹⁰ / s
Answer:
3.46 A
Explanation:
The force (F) exerted on a wire of a particular length (L) carrying current (I) through a magnetic field (B) at an angle (θ) to the magnetic field is given as
F = (B)(I)(L) sin θ
F = 3.13 N
B = 0.360 T
I = ?
L = 2.50 m
θ = 79°
3.13 = (0.360 × I × 2.5 × sin 79°)
0.8835 I = 3.13
I = 3.54 A
But this is the resultant current in this magnetic field.
Since the two wires are conducting current in opposite directions,
Resultant current = 7 - (current in the other wire)
Current in the other wire = 7 - 3.54 = 3.46 A
Answer:
The energy goes from <u>the ground state</u> to <u>the excited states</u> above it.
