Answer:
I' = 2.34 kg.m².
Explanation:
Given ,R= 40 cm = 0.4 m
m = 28 kg
d= 6 cm = 0.06 m
The mass moment of inertia of the cylinder about center given as
By using Parallel axis theorem
Now by putting the values
I'=2.34 kg.m²
There the answer will be 2.34 kg.m².
Answer:(b)
Explanation:
Given
Electric current flowing through the horizontal wire towards the observer's face.
The direction of the magnetic field is given by the right-hand thumb rule, i.e. place the thumb in the direction of current and the wrapping of fingers will give the direction of the magnetic field
the direction of the magnetic field will be counterclockwise as observed by an observer.
Answer:
The answer to your question is letter A. r = 1.07 x 10⁻¹⁴ m
Explanation:
Data
F = 2 N

q = 1.6 x 10 ⁻¹⁹ C
k = 8.987 Nm²/C²
Formula
Solve for r
Substitution
Simplification
r =
r =
Result
r = 1.07 x 10⁻¹⁴ m
Answer: Got It!
<em>Explanation: </em>let s = speed at launch
v = 0 at top = s sin 63 - g t
so at top
t = s sin 63/g = .0909 s
h = 13.6 = s sin 63 t - 4.9 t^2
13.6 = .081s^2 - .0405 s^2
s^2 = 336
s = 18.3 m/s
0 0
