Answer:
Option (2) is correct.
The energy density of an electromagnetic wave is equally divided between the magnetic and electric fields.
Explanation:
An electromagnetic waves are the waves which are produced when the oscillating electric and magnetic field are interact each other perpendicular to each other. The direction of propagation of electro magnetic waves is perpendicular to each electric and magnetic fields.
The energy associated with the electromagnetic waves is equally distributed in form of electric and magnetic fields.
So, the correct option is (2).
Answer:
Upward.
Explanation:
A large reduction in the current account deficit will place Upward pressure on the home currency value, other things being equal.
When their currency's value decreases, this means the valuation of foreign assets are rising. This further decreases the deficit in the current account. Additionally, a reduced currency value tends to increase export markets when prices become more cutthroat. Export demand falls as prices rise with inflation setting in.
Answer:
P = 2.18 atm
Explanation:
The strategy here here is to use the ideal gas law
PV = nRT
since we know the temperature, volume and the n, the number of moles is mass/MW, and R is the gas constant 0.08205 LatmK⁻¹mol⁻¹:
MW HI = 127.91 gmol⁻¹
P = ( mass / MW ) x R x T / V
P= (50.0 g / 127.91 gmol⁻¹ ) x 0.08205 LatmK⁻¹mol⁻¹ x 340 K/ 5.00 L
P = 2.18 atm
( rounded to three significant figures which is the number of significant figures for temperature, mass and volume )
