Answer:

Yes, you can twist or break parts of your body if you do not stretch before working out. It is always important to stretch even if you are doing activities such as gymnastics and karate.

The magnitude of the electric current is inversely proportional to the _____ of the circuits in R2D2.
nika2105 [10]
According to Ohm's Law, the voltage is equal to the current multiplied by resistance. Presenting the law in equation form:

V = IR

This law still applies in an R2-D2 droid circuit. Rearranging the equation:

I = V/R

Hence, the current is inversely proportional to the resistance.

How does our body control blood pressure?
k0ka [10]

Short-term regulation of blood pressure is controlled by the autonomic nervous system . Changes in blood pressure are detected by baroreceptors. These are located in the arch of the aorta and the carotid sinus. Increased arterial pressure stretches the wall of the blood vessel, triggering the baroreceptors.

What force is described as the attraction between a sample of matter and all other matter in the universe?
Vinil7 [7]

Answer:

Gravitational Force

Explanation:

Gravitational force also called gravity or gravitation is an attractive force that keeps two objects in space. Gravitational force is an attractive force that tends to pull matters together. Every objects in the universe experience gravitational pull.  Planets, stars, galaxies, are held together by gravity. It is a weak force. The weight of an object is the product of gravitational force acting on its mass.

Newton's Law of Universal Gravitation states the force of attraction between two masses m₁ and m₂ in the universe is directly proportional to the product of their masses and inversely proportional to the square of their distance apart.

                                 F = G\frac{m_{1}m_{2}}{r^2}

Where;

F is the gravitational force,

G is the gravitational constant = 6.67 × 10¹¹ m³/kg/s,

m1 and m2 are the masses of the objects,

r is the distance between the centers of the masses

What is science and physics?​
Ilya [14]

Answer:

PHYSICS - Physics is the natural science that studies matter, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.

<u>SCIENCE -</u> Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE.

This is all I got, but if you want to know more or need more, i’m sure there are websites that have more info.
