E = Energy m = Mass c = Speed of light.
Hi , basically the atmosphere is made up of 78% of nitrogen, nitrogen is very special and important because if the air was just made up of oxygen the air that we breath would be very flammable and toxic .That's why we have nitrogen.
Answer:
Explanation:
Magnitude of magnetic field due to a current carrying conductor
= ( μ₀ / 4π ) x 2I / d , I is current , d is distance from wire . This formula has been derived from Ampere's Law.
= 10⁻⁷ x 2 x 23 / 10 Current given I = 23
= 46 x 10⁻⁸ T .
Magnetic field due to current 17 A
10⁻⁷ x 2 x 17 / 10
= 34 x 10⁻⁸ T .
Magnetic field due to current 11 A
10⁻⁷ x 2 x 11 / 10
= 22 x 10⁻⁸ T .
magnetic field due to current 17 A and 11 A are in same direction so total magnetic field
= 34 x 10⁻⁸ + 22 x 10⁻⁸
= 56 x 10⁻⁸ T
magnetic field due to current 23 A in opposite direction so total magnetic field
= 46 x 10⁻⁸ - 56 x 10⁻⁸
= - 10 x 10⁻⁸ T
Magnitude = 10 x 10⁻⁸ T .
Answer:
A. Highly viscous and associated with violent eruptions
Explanation:
Most silica rich magma have high viscosity and huge amount of trapped gases within them. As they continue to upwell and expand, the gases causes violent eruptions near Volcanoes. Most granitic/rhyolitic magma are silica rich.
