Answer:
The primary components in volcanic gas are water vapor, carbon dioxide and sulfur (either sulfur dioxide or hydrogen sulfide). But you can also find nitrogen, argon, helium, neon, methane, carbon dioxide and hydrogen. Approximately 60% of total emissions released by volcanoes is water vapor, and carbon dioxide accounts for 10 to 40% of emissions.
Explanation:
Answer:
Water vapor
Explanation:
The magma consists of dissolved gases when these gases produce the force the volcanic eruption takes place. The volcanic gases come out and their volume is increased tremendously. The gases present in the volcano are listed below:
The volcanic gases consist of water vapors, carbon dioxide, and sulfur.
These three are the primary gases but the water is present in a higher amount.
The percentage of water is 60%.
The carbon dioxide present in 10-40%.
Other gases present in volcanos are nitrogen, argon, helium, neon methane, and hydrogen.
Hope this helps, Let me know if I am wrong ( I am pretty sure that am not) but let me know anyway..., OH! and Good LUCK! :D ;P
You (50 kg) are standing on a skateboard when your friend throws a 5 kg ball at 10 m/s towards your head. You catch the ball to save your face. Describe your motion after you catch the ball, use numbers.ā
Answer:
vā = 1 [m/s].
Explanation:
This problem can be solved by using the principle of conservation of linear momentum. Where momentum is conserved before and after catching the snowball.
[tex]P=m*v[/tex]
where:
P = linear momentum [kg*m/s]
m = mass [kg]
v = velocity [m/s]
[tex]P=m*v\\P=5*10\\P=50[m/s][/tex]
As the momentum is conserved, it will be the same as that received by the person who catches the snowball.
[tex]50= 50*v_{1}\\v_{1}=1[m/s][/tex]
That is, the person who catches the snowball moves backwards with a speed of 1 [m/s].
A circuit consists of a 12 V battery connected across a single resistor. If the current in the circuit is
3 A, calculate the size of the resistor
Answer:
4 Ohms
Explanation:
Apply the formula:
Voltage = I (current) . Resistance
You can change it the way you want to use for your purpose.
In this case...
R = V/I
R = 12/3
R = 4 Ohms (Ohm is the unit of measurement of eletrical resistance)
Calculate the work done in lifting 200 kg of water through a vertical height of 6 metres
(g = 10 m/s)
(A) 5000 J
(B) 12000 J
(C) 25000 J
(D) 15000 Jā
Answer:
[tex]\bf\pink{(C)\:12000\:J}[/tex]Explanation:
Given :-[tex]\sf\red{Mass = 200 \ kg}[/tex][tex]\sf\orange{Gravity = 10 \ m/s}[/tex][tex]\sf\green{Height = 6 \ m}[/tex]Need to find :-[tex]\sf\blue{Work \ done}[/tex]Formula required :-[tex]\sf\purple{Work \ done = Mass \times Gravity \times Height}[/tex]Solution :-[tex]\to\:\:\sf\red{Work \ done = Mass \times Gravity \times Height}[/tex]
[tex]\to\:\:\sf\orange{Work \ done = 200 \times 10 \times 6}[/tex]
[tex]\to\:\:\sf\green{Work \ done = 2000 \times 6}[/tex]
[tex]\to \:\ \sf\blue{ Work \ done = {\bf{\blue{1200\:J}}}}[/tex]
Hence, [tex]\bf\green{(B)}[/tex] is the correct option.
