Im not sure this is correct but, i think thats because the wire connected at the negative side. The current go from positive to negative and thats why the bulb not light, also the bulb location is not at the center of the battery which explain why there's no current at the upper side.
Hope you understand. Sorry if my english sucks YEET
Answer:
Explanation:
1.3 g = 1.3 / 2 = .65 moles of hydrogen .
.65 moles = 6.02 x 10²³ x .65 molecules
Translational kinetic energy of one molecule = 1/2 mc² where c is rms speed = 1/2 x 2 x 1.67 x 10⁻²⁷ x ( 1600 )² = 42752 x 10⁻²⁵ J
Translational kinetic energy of .65 moles = 6.02 x 10²³ x .65 x 42752 x 10⁻²⁵ J
= 1673 J approx .
B ) Total thermal energy and total translational kinetic energy are same so
Thermal energy of gas = 1673 J
C ) Net content of thermal energy = 1673 + 500 - 2000 = 173 J
If c be the rms speed
1/2 x 2 x 1.67 x 10⁻²⁷ x .65 x 6.02 x 10²³ c² = 173
6.534 x 10⁻⁴ c² = 173
c² = 264769
c = 514.56 m /s
Answer:
A i think but i could be wrong
Explanation:
Answer:
For object A
m = 5 kg , v= -11 j
For B object
m = 6 kg , v= 5 i +8.7 j
For object C
m = 10 kg , v= -10 i
We know that
Linear momentum P= m v kg.m/s
a) A and C
Momentum in y direction
Py=- 5 x 11 j= - 55 j kg.m/s
Momentum in x direction
Px=- 10 x 10 j= - 100 i kg.m/s
b) B and C
Momentum in y direction
Py=6 x 8.7 j= 52.2 j kg.m/s
Momentum in x direction
Px=( 6 x 5 - 10 x 10 ) i = - 70 i kg.m/s
c) A ,B and C
By using data of a and b
Momentum in y direction
Py= 6 x 8.7 - 5 x 11 j= -2.8 j kg.m/s
Momentum in x direction
Px= 6 x 5 -10 x 10 i = -70 i kg.m/s
Answer:
18*10^10 meters
Explanation:
V= d/t 10 mins = 600 seconds
3*10^8 = d/600s
(3*10^8)*(6*10^2) = d
d = 18*10^10 m
