Explanation:
Answer:
The mass of the bat is 1.09 kg.
Explanation:
Given that,
The balance point of the glove, x = 74.9 cm
Mass of the glove, m = 0.56 kg
Center of mass of the baseball bat, C = 25.3 cm
Let M is the mass of the bat. The center of mass is given by the formula as :

X is 0 as it is at a end


M = 1.09 kg
So, the mass of the bat is 1.09 kg. Hence, this is the required solution.
Answer: a. (Q), (T), (E)
b. (Q), (T), (E), (W)
Explanation: <u>Thermal</u> <u>Energy</u> and Temperature are closely related: when the temperature rises causing atoms or molecules to move, thermal energy is produced. Thermal energy is the energy within the system.
<u>Mechanical</u> <u>Work</u> is the amount of energy transferred due to an applied force.
<u>Chemical</u> <u>Energy</u> is the energy contained in the bonds of chemical structures of the molecules released when a chemical reaction happens.
Given the explanations, let's analyse the situations:
a. For an ice cube to be melting, it has to be absorbing heat, which means its thermal energy is changing and, consequently, so does its temperature;
b. First, the gas inside the cylinder reaches a thermal equilibrium, which means its thermal energy and temperature changed. Since there were exchange of heat to reach the equilibrium, the gas absorbed or gave off heat. After the equilibrium, when the piston starts to be moved, the energy of the pressure is transferred to the gas, so mechanical work had been done.
