Answer:
When same-sized team members are placed on each side of the rope, the sizes of the arrows on both sides remain the same.
Explanation:
This is the answer on Plato
Answer:
d) False. If the angular momentum is zero, it implies in electro without turning, which would create a collapse towards the nucleus, so in both models the moment must be different from zero
Explanation:
Affirmations
a) true. The orbits are accurate in the Bohr model and probabilistic in quantum mechanics
b) True. If both give the same results and use the same quantum number (n)
c) True. If in angular momentum it is quantized, in the Bohr model too but it does not justify it
d) False. If the angular momentum is zero, it implies in electro without turning, which would create a collapse towards the nucleus, so in both models the moment must be different from zero
Answer:
1.) 11 km/s
2.) 9.03 × 10^-5 metres
Explanation:
Given that an electron enters a region of uniform electric field with an initial velocity of 64 km/s in the same direction as the electric field, which has magnitude E = 48 N/C.
Electron q = 1.6×10^-19 C
Electron mass = 9.11×10^-31 Kg
(a) What is the speed of the electron 1.3 ns after entering this region?
E = F/q
F = Eq
Ma = Eq
M × V/t = Eq
Substitute all the parameters into the formula
9.11×10^-31 × V/1.3×10^-9 = 48 × 1.6×10^-19
V = 7.68×10^-18 /7.0×10^-22
V = 10971.43 m/s
V = 11 Km/s approximately
(b) How far does the electron travel during the 1.3 ns interval?
The initial velocity U = 64 km/s
S = ut + 1/2at^2
S = 64000×1.3×10^-6 + 1/2 × 8.4×10^12 × ( 1.3×10^-9)^2
S =8.32×10^-5 + 7.13×10^-6
S = 9.03 × 10^-5 metres
Answer:5.21 N
Explanation:
Given
B=5.210 T
I=2 A
L=0.5 m
Given Wire is perpendicular to Magnetic field
F=5.210 N
as 1 Tesla =1 N/A/m
Uranus was originally discovered by Sir William Herschel in 1781. Neptune is the 8th planet from the sun making it the most distant in the solar system. Neptune is the smallest of the Ice Giants. The atmosphere of Neptune is made of Hydrogen, helium, And some methane. Uranus make one trip around the sun every 84 earth years. Uranus has the coldest temperatures of any planet. I hope This helps!!!
