Answer:
C. Perpendicular to one another and perpendicular to the direction of wave propagation.
Explanation:
Electromagnetic waves are the waves which arise due to vibrations of both electric and magnetic fields. In electromagnetic waves, the electric and magnetic fields are perpendicular to each other and also both the electric and magnetic fields are perpendicular to the direction of wave propagation i.e. if the wave is propagating in x-direction then electric field can be in z-direction and magnetic field can be in y-direction since all the three axes are perpendicular to each other.
Okay I will thanks rlly got me thinking about life
Answer:
40 W
Explanation:
The maximum wattage (power) that Mike can use is given by:
where
V is the voltage
I is the maximum current
In this problem, we have:
is the voltage
is the maximum current available
Therefore, the maximum power that could be used is
Thrust given = 5.26N
Δmass = 12.7g
Δtime = 1.9seconds
exhaust speed = ve
The thrust acting on the rocket is = veΔm/ Δt
So, ve = thrust / (Δm/Δt) = 5.26 x 1.9/12.7 x
ve = 707 m/s
<h3>What is Thrust?</h3>
- Newton's third law uses the concept of thrust to quantitatively quantify a reaction force. A force of similar size and in the opposite direction will be applied to a system when mass is expended or accelerated in one direction.
- Thrust is another name for the force that is exerted to a surface normal to or perpendicular to it.
- The amount required to propel 1 kilogramme of mass at a velocity of 1 metre per second per second is measured as force, and hence thrust, using the International System of Units (SI) in newtons (symbol: N).

Answer:
D. 12 cm
Explanation:
A node is a point on a standing wave that does not vibrate.
The nodes of a standing wave are shown in the following sketch.
The red dots are the nodes of the standing wave.
It is observed that the distance between two adjacent nodes is half the wavelength of the wave.
Therefore, if the wavelength of the wave is 24 cm, then the distance from one node to the net must be 24 / 2 = 12 cm.
Hence, choice D is the correct answer.
