The correct answer is 15 N.

Explanation:

The mechanical advantage of a machine is calculated as,

M.A = Output Force/ Input Force

Given, mechanical advantage=2

Output force = 30 N

Substituting the values,

2=\frac{30}{I.F}

Input force = 15 N

∴ The input force must be 15 N.

slavikrds [6]
The working equation for this is: E = F/Q, where E is the strength of electric field, F is the force and Q is the charge. The force is equal to:

F = mg = (0.13/1000 kg)(9.81 m/s²) = 1.2753×10⁻³ N

The charge of he excess electrons is equal to:
Q = (-1.6021766208×10⁻¹⁹ C/electron)(1×10¹⁰ electrons)
Q = -1.6021766208×10⁻⁹ C

E = 1.2753×10⁻³ N/-1.6021766208×10⁻⁹ C
E = -795,979.66 N/C

Clearly distinguish between mass, weight, and volume.
USPshnik [31]

The mass tells you the amount of matter or substance that makes up an object.

The weight tells you the measure of the matter.

The volume tells you the amount of space/size taken up

Give an examplea of newtons law of acceleration
coldgirl [10]

The 2nd Law of Motion states acceleration is produced when a n unbalanced force acts on an object (mass) The more mass the object has the more net force has to be used to move it.

Examples:

If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.

It's easier to push a empty shopping cart then a full one, because the full one has more mass than the empty one. This means more force is required to push the full shopping cart.
