If I did my math right I believe 13 is the 9.3 seconds and 14 is the first option because of logic. The question basically says, how does the height change and the answer is the first one because it gets higher then lower, or increases then decreases.
The material can transmit heat by energy transfer through collision of atoms. The elements that has a high ability of transmitting heat within their material are the metals. They are said to have high thermal conductivity. As the metal heats up, because the atoms are closely packed, they easily transfer heat through conduction. For example, copper is used in electrical wirings because it has a high thermal conductivity.
Answer:
d. Its magnitude and its direction both remained the same.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
The law of conservation of momentum states that the total linear momentum of any closed system would always remain constant with respect to time.
This ultimately implies that, the law of conservation of momentum states that if objects exert forces only on each other, their total momentum is conserved.
In this scenario, a rubber ball moving at a speed of 5 m/s hit a flat wall and returned to the thrower at 5 m/s. Thus, the statement which correctly describes the momentum of the rubber ball is that its magnitude and its direction both remained the same because its velocity didn't change while returning to the thrower.
Answer:
the concrete because the concrete absorbs the suns energy, making it hot
