The correct option is C.
J.J Thompson demonstrated that Dalton's model of the atomic theory was wrong by showing that atoms are made up of sub particles, this is contrary to the report that Dalton gave about atoms. In his experiment, Dalton reported that atoms are indivisible, that is, they can not be broken down into smaller particles. J.J Thompson on the other was able to show through his cathode ray experiment that atoms are made up of smaller particles called electrons.
Answer:
South Carolina and Georgia, the main cash crops were indigo and rice. Explanation:
trust me
Answer:
the easy way to describe this is to use a light as an example.
Explanation:
Voltage is pretty much the loop used to help use a lightbulb to emit light. Without voltage, we would be unable to use lightbulbs. This applies to much more than a lightbulb, but it's the easiest way to describe how voltage works.
1. Answer;
Acceleration is;
-2.46m/s²
Explanation;
The initial velocity is 8.6 m/s, the final velocity = 0 m/s
The time is 3.5 seconds
Using the equation;
V =U + at
but V =0 , -U = at
a = -U/t = -8.6 /3.5
= -2.457 m/s²
= -2.46 m/s² (2 d.p)
2. Answer;
The distance is ;
=15.1 m
Solution;
a = -2.46 m/s², v=0 and U = 8.6 m/s
Using the equation;
V² = U² +2as (where s is the distance)
but v =0, thus, s =U²/2a
= -8.6²/ 2(-2.46)
= -73.96 /-4.92
= 15 .1 m (1 d.p)
Answer:
its 1
Explanation:
Several factors can increase the rate of a chemical reaction. In general, anything that increases the number of collisions between particles will increase the reaction rate, and anything that decreases the number of collisions between particles will decrease the chemical reaction rate.
