5 0

Answer:

28.6666666667 or 29

Explanation:

the formula for voltage (if power is involved)

V = P/i

86 ÷ 3

28.6666666667

if you want your can round to get a more simple answer

29

What is the equivalent resistance for a series circuit with three resistors: 5.0 ohms, 2.0 ohms, and 12.0 ohms?
KonstantinChe [14]
There are several information's already given in the question. Based on those given information's, the answer can be easily deduced.
Equivalent resistance = 5 + 2 + 12
                                   = 19 ohms

From the above deduction, it can be deduced that the correct option among all the options that are given in the question is the first option or option "A". I hope that this is the answer that has actually come to your desired help.

Equilibrium occurs when : Answers:
prohojiy [21]

Answer:

All are correct.

Explanation:

The equilibrium of an object occurs when:

1. The net force on the object is zero: When the number of forces acting on an object and the sum of all the forces is zero, then we say that the net force acting on the object is zero. It means that the net acceleration of the object is zero, it means the object is at rest or moving with constant velocity.

2. All forces acting on an object are balanced: When a number of forces acting on the object and the net force is zero it means all the forces are balanced. So, that the object has either zero velocity or moving with constant velocity.

3. The sum of +X forces on an object equals the sum of the - x forces: As the forces in + X axis direction is equal to the forces in - X axis direction, it means again the net force on the object is zero.

4. The sum of upward forces equal to the sum of downward forces: As the sum of forces in upwards direction is equal to the sum of forces in downward direction, it means the net force on the object is zero..

A train with mass 3.3 x 107 kg starts from rest and accelerates to a speed of 42
Natasha2012 [34]

Answer:

kinetic energy of the train = 2,910.6 x 10⁷ joule

Explanation:

Given:

Mass of train = 3.3 x 10⁷ kg

Speed of train = 42 m/s

Find:

kinetic energy of the train

Computation:

kinetic energy = (1/2)(m)(v²)

kinetic energy of the train = (1/2)(3.3 x 10⁷)(42²)

kinetic energy of the train = (1/2)(3.3 x 10⁷)(1,764)

kinetic energy of the train = (3.3 x 10⁷)(882)

kinetic energy of the train = 2,910.6 x 10⁷ joule
