<span>The answer is 6 Joules. The kinetic energy (KE) of an object is the product of half of the mass (m) of the object and the square of its velocity (v²): KE = 1/2m*v². We know that m = 0.75 kg and that v = 4 m/s. Therefore, KE = 1/2 * 0.75 kg * (4 m/s)² = 1/2 * 0.75 kg * 16 m²/s² = 6 kg*m²/s² = 6 J.</span>
Answer:
True
Explanation:
Because the resistors in series is the sum of the two resistors given as
R= R1+R2
While that of resistors in parallel is the sum of the reciprocal of the resistance given as
1/R = 1/ R1+ 1/R2
So that of series connection will be greater
The given statement "There is a set table of rate constants for the rate equation" is true.
Answer: Option A
<u>Explanation:</u>
The rate equation definitely has the need of set of table of rate constants. Rate constants are those which, in a reaction, describe whether it is fast, slow or moderate. And, if a set of rate constants is not available, one may take slow processes and have to wait a long time to predict the results.
And, if the reactions are fast, there is a chance of damage occurring to the surroundings. And since it is a constant, it is easier to determine the products of an intermediate steps, in a chemical reaction too.

Answer:
4.0 Kg
Explanation:
From the question given above, the following data were obtained:
Velocity (v) = 48 m/s
Kinetic energy (KE) = 4632 J
Mass (m) =?
Kinetic energy can be defined as the energy possess by a moving object. Mathematically, it is expressed as:
KE = ½mv²
Where
KE => kinetic energy
m => mass of object
v => velocity
With the above formula, we can obtain the mass of the object as follow:
Velocity (v) = 48 m/s
Kinetic energy (KE) = 4632 J
Mass (m) =?
KE = ½mv²
4632 = ½ × m × 48²
4632 = ½ × m × 2304
4632 = m × 1152
Divide both side by 1152
m = 4632 / 1152
m = 4.0 Kg
Therefore, the mass of the object is 4.0 Kg
