Answer:
thermodynamics
Explanation:
The laws of thermodynamics define a group of physical quantities, such as temperature, energy, and entropy, that characterize thermodynamic systems in thermodynamic equilibrium.
Answer:
The speed of projection is 34 m/s.
Explanation:
Height of building, h = 51 m
horizontal distance, d = 74 m
time, t = 8 s
Let the angle is A and the speed is u.
d = u cos A x t
74 = u cos A x 8
u cos A = 9.25 .... (1)
Use second equation of motion
Squaring and adding both the equations
An old sandwich rotting in a trashcan and building a tower out of magnetic blocks both are undergoing chemical changes.
<h3>
What are chemical changes?</h3>
Chemical changes are said to occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances.
Examples of chemical changes include burning of wood, cooking of pasta, rusting of metal , and rotting of sandwiches.
In conclusion, chemical changes involve the formation of new substances while Physical change is a temporary change.

Answer:
The capacitance of the capacitor is 31.84 μF.
Explanation:
Given;
power rating of the bulb, P = 100 W
voltage rating of the bulb, Vr = 100 V
operating voltage of the bulb, V= 141.4 V
frequency of the AC = 50 Hz
P = IV = 100 W
V = 100 V
I =
Ic = 1 A
The voltage across the capacitor is given by;
Therefore, the capacitance of the capacitor is 31.84 μF.
The crest is the top part of a transverse wave
ex: /\/\/\ the crests are at the top points of the wave
