Answer:
The glasses with different amounts of water make different sounds. ... This is because the empty glass only has air around it, so the glass vibrates quickly when it is hit, causing the high pitch sound. The glass full of water causes the glass to vibrate slower, and the sound you hear is at a lower pitch.

Answer:
Q = - 8501.99 j
Explanation:
Given data:
Specific heat of Al = 0.902 j/g.°C
Heat lost = ?
Mass of sample = 23.984 g
Initial temperature = 415°C
Final temperature = 22°C
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 22°C - 415°C
ΔT = -393°C
Q = m.c. ΔT
Q = 23.984 g× 0.902 j/g.°C × -393°C
Q = - 8501.99 j
Answer:
In equation form, Newton's second law of motion is a=Fnetm a = F net m . This is often written in the more familiar form: Fnet = ma. The weight w of an object is defined as the force of gravity acting on an object of mass m. ... Friction is a force that opposes the motion past each other of objects that are touching.
