Answer:
No,
Explanation:
An electromagnetic wave is made of vibrating electric and magnetic fields that continually induce each other; matter is not needed for this to occur.
Answer:
![dz=19217687.07\ m](https://tex.z-dn.net/?f=dz%3D19217687.07%5C%20m)
Explanation:
Given:
- initial gauge pressure in the container,
![P_0=2.02\times 10^{5}\ Pa](https://tex.z-dn.net/?f=P_0%3D2.02%5Ctimes%2010%5E%7B5%7D%5C%20Pa)
- atmospheric pressure at sea level,
![P_a=1.01\times 10^5\ Pa](https://tex.z-dn.net/?f=P_a%3D1.01%5Ctimes%2010%5E5%5C%20Pa)
- initial volume,
![V_0=4.4\times 10^{-4}\ m^3](https://tex.z-dn.net/?f=V_0%3D4.4%5Ctimes%2010%5E%7B-4%7D%5C%20m%5E3)
- maximum pressure difference bearable by the container,
![dP_{max}=2.26\times 10^{5}\ Pa](https://tex.z-dn.net/?f=dP_%7Bmax%7D%3D2.26%5Ctimes%2010%5E%7B5%7D%5C%20Pa)
- density of the air,
![\rho_a=1.2\ kg.m^{-3}](https://tex.z-dn.net/?f=%5Crho_a%3D1.2%5C%20kg.m%5E%7B-3%7D)
- density of sea water,
![\rho_s=1.2\ kg.m^{-3}](https://tex.z-dn.net/?f=%5Crho_s%3D1.2%5C%20kg.m%5E%7B-3%7D)
<u>The relation between the change in pressure with height is given as:</u>
![\frac{dP_{max}}{dz} =\rho_a.g_n](https://tex.z-dn.net/?f=%5Cfrac%7BdP_%7Bmax%7D%7D%7Bdz%7D%20%3D%5Crho_a.g_n)
where:
dz = height in the atmosphere
= standard value of gravity
<em>Now putting the respective values:</em>
![\frac{2.26\times 10^{5}}{dz} =1.2\times 9.8](https://tex.z-dn.net/?f=%5Cfrac%7B2.26%5Ctimes%2010%5E%7B5%7D%7D%7Bdz%7D%20%3D1.2%5Ctimes%209.8)
![dz=19217.687\ km](https://tex.z-dn.net/?f=dz%3D19217.687%5C%20km)
![dz=19217687.07\ m](https://tex.z-dn.net/?f=dz%3D19217687.07%5C%20m)
Is the maximum height above the ground that the container can be lifted before bursting. (<em>Since the density of air and the density of sea water are assumed to be constant.</em>)
Answer:
The more velocity an object has the harder it is to slow it down
Explanation:
slow it down
Answer:
![1.1\times10^{4}m](https://tex.z-dn.net/?f=1.1%5Ctimes10%5E%7B4%7Dm)
Explanation:
The Schwarzschild radius can be calculated as follows:
![R=\frac{GM}{c^2}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7BGM%7D%7Bc%5E2%7D)
Where, <em>G</em> is the gravitational constant, <em>M</em> is the mass and <em>c</em> is the speed of light.
Mass of sun is 1.98×10³⁰ kg
![R=\frac{G\times 7.5M_{sun}}{c^2}\\ R=\frac{6.67\times10^{-11}\times(7.5\times1.98\times10^{30})}{(3\times10^8)^2}\\ \Rightarrow R=1.1\times10^{4}m](https://tex.z-dn.net/?f=R%3D%5Cfrac%7BG%5Ctimes%207.5M_%7Bsun%7D%7D%7Bc%5E2%7D%5C%5C%20R%3D%5Cfrac%7B6.67%5Ctimes10%5E%7B-11%7D%5Ctimes%287.5%5Ctimes1.98%5Ctimes10%5E%7B30%7D%29%7D%7B%283%5Ctimes10%5E8%29%5E2%7D%5C%5C%20%5CRightarrow%20R%3D1.1%5Ctimes10%5E%7B4%7Dm)
