Answer:

b.  in the oscillating electric and magnetic fields

Explanation:

Electromagnetic waves are formed when mutually perpendicular electric and magnetic field oscillate in space. Electromagnetic waves carry electromagnetic radiant energy from the electromagnetic filed. Electromagnetic waves do not require a medium to propagate. The direction of propagation of the electromagnetic wave is perpendicular to the direction of the vibrating electric and magnetic field.

Ugo [173]

Answer:

Let's say we were Subtracting 3-2=? To Find the Answer we would Subtract  2 from 3 which is 1 Simple our answer is 1  But let's say the Question is 3 - 1= ? to find this answer we would subtract 1 from 3 which is 2 Let's say you were subtracting 3-3=? to do this we take 3 away from 3 now 3 is 0 so our answer is 0 so there are 3 different problems we can make with 3 we could make more but I'm just telling the basics Hope I Helped Bye :)

Which has more mass: an armful of feathers or an armful of lead? which has more volume: a kilogram of feathers or a kilogram of
valina [46]
Mass is related to weight. It measures the resistance of the substance to acceleration when a net force is applied.
Therefore: armful of lead has more mass

volume measures the amount of 3-dimensional space that an object occupies.
Therefore: kilogram of feather has more volume as it is less dense.

density is the mass per unit volume. Since armful of lead has more mass than a handful of feathers, while kilogram of feather has more volume than a kilogram of lead.
Therefore: kilogram of lead has higher density.

2. If 1.75 L of a gas is at 700. K and is under 250. kPa of pressure, what will the new
Andrews [41]

Answer:

Final volume is 3.50L

Explanation:

It is possible to find volume of a gas using combined gas law:

\frac{P_1V_1}{T_1} =\frac{P_2V_2}{T_2}

<em>Where P is pressure, V is volume and T is temperature of 1: initial state and 2: final state</em>

If initial state of the gas is:

1.75L of a gas is at 700K and is under 250kPa of pressure

And final state is:

298K and 53.2kPa.

Replacing:

\frac{250kPa*1.75L}{700K} =\frac{53.2kPa*V_2}{298K}

0.625L = 0.1785*V₂

<em>3.50L = V₂</em>

Thus, <em>final volume is 3.50L</em>
