Answer:

c. The truck with greater speed

Explanation:

Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;

a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.

b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

K.E = \frac{1}{2}MV^{2}

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents speed or velocity measured in metres per seconds square.

From the above formula, we can deduce that the kinetic energy of an object is directly proportional to the square of the value of its velocity or speed.

Hence, the truck with greater speed would have a greater amount of kinetic energy.

What is a word that means have adapted to antibiotics?
zzz [600]
If you are referring to bacteria, the word "resistant" is applicable, as bacteria adapt to antibiotics by undergoing natural selection to enhance antibiotic-resistant genes.
If you are referring to humans or higher-order species, "grown tolerant" could be used to say that perhaps a certain antibiotic dosage is no longer as effective as it used to be and that a higher dosage is needed. "Acclimated" can also be used to say that an organism's body had to adjust to the exposure to a new, unfamiliar antibiotic.
