Answer:
E(x,t) = Emaxcos(kx - ωt + φ),
B(x,t) = Bmaxcos(kx - ωt + φ).
Explanation:
E is the electric field vector, and B is the magnetic field vector of the EM wave. For electromagnetic waves the electric field E and the magnetic field B are always perpendicular to each other and perpendicular to the direction of propagation. The direction of propagation is the direction of E x B.
Yes, the above-given statement is true
<u>Explanation:</u>
- The product of the mass x the velocity will be the same for both. Momentum is the action of a body with a particular mass through space and there is the conservation of momentum.
- Momentum is described as the mass of the object multiplied by its velocity.
- <u>Momentum (p) = Mass (M) * Velocity (v)</u>
- Therefore for two objects with many masses to have a similar momentum, then the lighter one has to be moving quicker than the heavier object.
W= 540 N
M=?
G= 9.8
W=mg
540=mx9.8
M=540\9.8
M=55.10
Answer:
Explanation:
When the velocity of an object changes, it would experience an impulse. If the mass of the object stays the same, and that the object moves along a line, the value of the impulse would be:
, where
- is the mass of the object, and
- is the change in the velocity of the object.
On the other hand, the change in the object's velocity can be found with the equation:
.

Note that and are of opposite signs. The reason is that the object's velocity has changed direction in this period.

Because in Bohr’s model for hydrogen atom we consider only Coulombic interactions between one proton and one electron.
It cannot be extended for other atomic species containing more than one electron. Because in this case in addition to the interaction between nucleus and electron there arises the interactions between electron and electron of the same species. Bohr couldn't solve this problem and this problems are successfully explained on the basis of later developed quantum mechanics.o
