Answer:
False. The net force is Zero
Explanation:
To answer this question we propose the solution of the problem.
We have a toy where balls come in and out after crashes between them, this toy forms our system, so all the balls are parts of the system, when the balls collide with each other according to Newton's third law force and action and reaction, so it has the same magnitude, but opposite direction, this is each is applied to some of the objects.
In conclusion of the previous one for the system the net force is Zero, all are internal. Therefore, the only thing that happens is a redistribution of speeds according to the conservation of the moment.
Let's review the answer.
False. The net force is Zero
Answer:
high frequent sound
Explanation:
because if its low than its slower.
Answer:
0.3 N
Explanation:
i = 400 A
B = 30 x 10^-6 T
L = 25 m
Force due the current carrying conductor placed in a magnetic field
F = B i L SinФ
where, Ф be the angle between length vector and magnetic field vector
F = 30 x 10^-6 x 400 x 25 = 0.3 N

Answer:
Explanation:
Given that,
Mass of the object, m = 29 kg
Torsion constant of the wire, K = 1.14 N-m
Number of cycles, n = 98
Time, t = 74 s
To find,
The rotational inertia of the object.
Solution,
Relationship between the moment of inertia, time period and the torsion constant of the spring is given by :
Where I is the moment of inertia
K is spring constant
Let T Is the time period of oscillation, such that,
So, the rotational inertia of the object is .
