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:
More force is needed for more mass. Therefore, if the mass is greater and the force is not enough then the object will less likely accelerate
Answer:
464.3 N
Explanation:
Given parameters are:
I = 0.065 
L = 0.025 m
R = 0.28 m
= 0 m/s
= 5 m/s
t = 0.1 s
Hence, 
We must connect two torque equations to find the answer.
Where 
Hence, 
Thus, 
N
Answer:
Scalar quantity can never be Negative. Because scalar has only magnitude not direction. And magnitude can't be negative.
Explanation:
Reflection and refraction are two different phenomenons. In case of reflection, wave bounces back into the same medium after incident with the interface of two mediums. Reflection will happen if surface is shiny as well as smooth. If surface is irregular, one will get diffused reflection. Refraction means bending of light when waves travel from one medium to another
