Rust is a type of iron oxide. When oxygen and a substance collide it creates oxides. This is a process called oxidation which is a type of chemical weathering.

Who discovered the strong nuclear force
Brilliant_brown [7]

Answer:

James Chadwick

Explanation:

James Chadwick discovered that the nucleus of each atom contains neutrons in 1932. Shortly after this, Eugene Wigner suggested that the electromagnetic force is not involved in holding the nucleus together and that there are two different nuclear forces. We now refer to these as the strong and weak nuclear forces.

Calculate the acceleration of a car (in m/s^2) that accelerates from 0 to 30 m/s in 6 s along a straight road.
tester [92]

Answer: 5 m/s^2

Explanation: In order to solve this question we have to use the kinematic equation given by:

Vf= Vo+a*t  where V0 is zero.

we know that it takes Vf( 30 m/s) in 6 seconds

so

a=(30 m/s)/6 s= 5 m/s^2

Aleks04 [339]

Answer:

<u><em>1) if they are moving away from each other it will take 1.43 secs</em></u>

<u><em>2) if they are moving towards each other then it will take 1.11 secs</em></u>

Explanation:

Distance between them is 10 m

Speed  ( if they are moving towards each other)= distance/time

time = 10/8+1

time = distance / speed= 10/9=  1.11 secs

if they are moving away from each other than it will take

time = 10/8-1= 10/7= 1.43 secs
