Answer:
The pitch stays the same I think
Explanation:
Because they behave just like all the electromagnetic waves of the spectrum. Same equations, just shorter wavelengths and more energy.
Hope you get it :)
Mass = force/acceleration
M=24/ 6
m=4 N
Answer:
Explanation:
From the information given:
The avg. velocity post the window is;
= velocity located at the top of the window
= velocity situated at the bottom of the window
Using the equation of kinematics:
Hence,
To determine the average velocity as follows:
where;
= velocity gained when fallen through the height h.
Similarly, using the equation of kinematics, we have;
Thus, the velocity at the ground is;
Answer:
T = 486.6 K
Explanation:
The final temperature of the block can be found using the following formula:
where,
Q = Thermal Energy Transferred = 3.35 x 10⁵ J
m = mass of aluminum block = 2 kg
C = Specific Heat = 897 J/kg.K
ΔT = Change in Temperature = T - 300 K
T = Final Temperature of the Block = ?
Therefore,
<u>T = 486.6 K</u>
