First of all, lets get our equation for Kinetic Energy (KE).
KE = 1/2 (mass) (speed)2
<span>Now, replace the words by adding the actual values. </span>
KE = 1/2(2 kg) x (45 m/s)^2
KE = 2025 J
Answer: Kinetic energy = 2025 Joules
Answer:
1. employment 2. mining process 3. pollution
Explanation:
I took the assignment, it is 100% correct. : )
The reaction releases heat and gives net energy to its surroundings. The energy needed to initiate the reaction is less than the energy released.

HOPE THIS HELPS! ^_^
1) 7.15 * 10^6
since the exponent of the scientific notation is positive, move 6 places to the right.
so, <em>7.15 * 10^6 = 7150000</em>
2) 3.03 * 10^-8
Since the exponent of the scientific notation is negative, move the decimal point 8 places to the left.
so,<em> 3.03 * 10^-8 = 0.0000000303</em>
<em />
3)<em> </em>4.9 * 10^-1
since the exponent of the scientific notation is negative, move 1 decimal place to the left.
so,<em> 4.9 * 10^-1 = 0.49</em>
<em />
4) 2.886 * 10^5
since the exponent of the scientific notation is positive, move 5 decimal places to the right.
so,<em> 2.886 * 10^5 = 288600</em>
