Answer:

The correct answer is because of the current.

Explanation:

A boy accidentally touched an electric wire and quickly withdrew his hand. This is because having contact with an electric wire causes a tingling sensation. This causes the person to quickly remove the hand from the wire. The impulse is produced by a contraction of the nervous system. If you grasp the cable with the palm of your hand, it will close and be attached to the cable.

Have a nice day!

Acceleration of a free-falling object in a frictionless environment increases as a function of time.

Digiron [165]

A free-falling object is an object moving under the effect of gravitational forces alone

The correct option to select for the True or False question is False

The reason the above selected option is correct is as follows:

According to Newton's second law of motion, we have;

Force = Mass × Acceleration

The force of gravity is $F_{g} =G \cdot \dfrac{M \cdot m}{r^{2}}$

Where;

$G \cdot \dfrac{M }{r^{2}} = Acceleration \ due \ to \ gravity , \ g \approx 9.81 m/s^2$

m = The mass of the object

∴ The force acting on an object in free fall, $F_g$ = m × g

Therefore the acceleration of an object in free fall is the constant acceleration due to gravity, and it therefore, does not change with time

The correct option for the question, acceleration of a free-falling object in a frictionless environment increases as a function of time is False

Heartburn is a form of indigestion felt as a burning sensation in the chest when stomach acid comes back up into the esophagus.

xenn [34]

The antacid is basic so it neutralizes acidity or lowers it. Then if it goes into the esophagus, it's not as strong and it doesn't hurt, and it also calms your stomach because the acidity in your stomach is also lower. Antacids are therefore taken by many people, especially as they grow older and things like heartburn become more common.
