Two identical soccer balls are rolled toward each other. What will be true after they collide head-on? (2 points)
Vlada [557]

well it depends on how much force was added but if they both have the same amount of force and they were rolled at the same time either they will bounce backwards or roll backwards not thats your question will they roll backwards are bounce backwards?

Why do hydrogen and oxygen bond?
ivanzaharov [21]
Hydrogen and oxygen bond because when more molecules are present, as is the case with liquid water, more bonds are possible because the oxygen of one water molecule has two lone pairs of electrons, each of which can form a hydrogen bond with a hydrogen on another water molecule.

What is hydrometer? Describe its use and any one type of hydrometer.​
nexus9112 [7]

Answer:

An instrument for measuring the density of liquids.

Explanation:

A hydrometer is an instrument used to determine specific gravity. It operates based on the Archimedes principle that a solid body displaces its own weight within a liquid in which it floats. Hydrometers can be divided into two general classes: liquids heavier than water and liquids lighter than water.

Thermohydrometers is one type of hydrometer.

Dr. John Paul Stapp was U.S. Air Force officer who studied the effects of extreme deceleration on the human body. On December 10
Nuetrik [128]

Answer:

acceleraions 5.76g and 20.55g

Explanation:

This constant acceleration exercise can be solved using the kinematic equations in one dimension

    Vf = Vo + a t

As part of the rest Vo = 0

    a = Vf / t

    a = 282/5

    a = 56.4 m / s2

In relation to the acceleration of gravity

    a ’= a / g = 56.4 / 9.8

    a ’= 5.76g

To calculate the acceleration to stop we use the same formula

     a2 = 282 / 1.40

     a2 = 201.4 m / s2

 This acceleration of gravity acceleration function is

     a2 ’= 201.4 / 9.8

     a2 ’= 20.55g
