Answer:
Option D- 1,2 and 3
Explanation:
Gravity always acts on an object irrespective of height
Answer:
d.Energy as heat transferred into an object is determined by the amount of work done on the object.
Explanation:
Answer: velocity
Explanation: it's the rate of change of the objects position/ consistent change
Answer:
A
Explanation:
An antifreeze is a substance which when added to a liquid reduces the freezing point of the liquid. Hence the solution can only freeze at a lower temperature compared to the solvent. Examples of antifreeze includes salt and propylene glycol. Antifreeze are used in low temperature environments to prevent water from freezing quicky. Hence the answer is A.

<span>Let's first off calculate the kinetic energy using the formula 1/2MV^2. Where the mass, M, is 0.6Kg. And speed, V, is 2. Hence we have 1/2 * 0.6 * 2^2 = 1.2J. Since kinetic energy is energy due to motion; hence at point B the rubber has a KE of 1.2J and not 7.5J. So I would say that only the Mass and speed is actually true; While it's kinetic energy is not true.</span>
