Answer:
14 cm
Explanation:
F = (frac{uv}{u – v})
F = +ve
v = -ve
30 = (frac {25 {times} (-v)}{25 – (-v)})
v = (frac {25 {times} (-v)}{25+v})
v = 14cm
(Note that either negative or positive values go to show the positioning and hence, they are not a strong necessity in your final answer.)
So happy that i could help you!
Now this question could turn out to be easy for you!!
Answer;
- the direction the wire moves in
- the direction of the magnetic field
Explanation;
The direction of an electric current is also the direction in which a positive charge would move.
The direction of flow of electric current in a current carrying conductor such as a wire depends on a number of factors. These factors includes; the direction the wire moves in; that is current will flow towards the direction of a given wire or conductor.\
Secondly, the direction of magnetic field determines the direction of flow of electric current; this can be explained by the idea of induced current; the direction of induced current depends on the direction of magnetic field according the Fleming,s right hand rule.
Answer:
Explanation:
The given differential equation is
and y(0) = 0, y(L) =0
where T and ρ are constants
The given rewrite as
auxiliary equation is
Solution of this de is
y(0)=0 ⇒ C₁ = 0
y(L) = 0 ⇒
we need non zero solution
⇒ C₂ ≠ 0 and
solution corresponding these values
Answer:
Net force
I think it’s balanced force
Refer to the diagram shown below.
The basket is represented by a weightless rigid beam of length 0.78 m.
The x-coordinate is measured from the left end of the basket.
The mass at x=0 is 2*0.55 = 1.1 kg.
The weight acting at x = 0 is W₁ = 1.1*9.8 = 10.78 N
The mass near the right end is 1.8 kg.
Its weight is W₂ = 1.8*9.8 = 17.64 N
The fulcrum is in the middle of the basket, therefore its location is
x = 0.78/2 = 0.39 m.
For equilibrium, the sum of moments about the fulcrum is zero.
Therefore
(10.78 N)*(0.39 m) - (17.64 N)*(x-0.39 m) = 0
4.2042 - 17.64x + 6.8796 = 0
-17.64x = -11.0838
x = 0.6283 m
Answer: 0.63 m from the left end.
