Answer:
Can behave both as a particle and wave
Explanation:
Electromagnetic wave has the electric and magnetic wave propagating/oscillating together. Electromagnetic waves such as x Ray, gamma ray, radio waves are important in health care and modern information technology .
Electromagnetic waves have particles such as the electrons and protons. They are responsible for the existence of electromagnetic waves by the charged particles vibrating. Electromagnetic waves behave as waves majority of the time. Electromagnetic energy is released in distinct packs of energy called photons which are particles but acts like waves.
Answer:
B
Explanation:
i just did it on study island
Impulse=force x time
force=mass x acceleration due to gravity
force=
![300 \times 10 = 3000](https://tex.z-dn.net/?f=300%20%5Ctimes%2010%20%3D%203000)
impulse =3000 x 2.5= ( sorry i don't have a calculator right now so you must calculate this yourself)
I converted from kg to g because it is the standard.
Hope this helps you.
Answer:
3.69 V
Explanation:
By connecting across the resistor, the capacitor starts discharging.
The voltage across the capacitor when discharging is given by
![V = V_0e^{-t/T}](https://tex.z-dn.net/?f=V%20%3D%20V_0e%5E%7B-t%2FT%7D)
V is the voltage across it at time t,
is the initial voltage when fully charged,
T is the time constant
After one time constant, t = T. Then
![V = V_0e^{-T/T}= 0.369V_0](https://tex.z-dn.net/?f=V%20%3D%20V_0e%5E%7B-T%2FT%7D%3D%200.369V_0)
From the question, ![V_0 =10 \text{ V}](https://tex.z-dn.net/?f=V_0%20%3D10%20%5Ctext%7B%20V%7D)
![V = 10\text{ V}\times0.369 = 3.69 \text{ V}](https://tex.z-dn.net/?f=V%20%3D%2010%5Ctext%7B%20V%7D%5Ctimes0.369%20%3D%203.69%20%5Ctext%7B%20V%7D)
