Answer:
Physical indicates connected with, pertaining to, the animal or human body as a material organism: physical strength, exercise. Bodily means belonging to, concerned with, the human body as distinct from the mind or spirit: bodily pain or suffering.
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.
Answer:
Number of turns,
Explanation:
Given that,
The maximum strength of the Earth's magnetic field,
This field could be used with a rotating coil to generate 60.0-Hz ac electricity.
Let us assume that the coil must have to produce an rms voltage of 120 V and area per turn is 0.022 meter square.
The emf induced in the coil is given by :
N is the number of turns
f is the frequency
or
So, there are turns in the coil.
Answer:
B
Explanation:
Friction always eventually stops whatever is in motion.
