Answer:
The question has some probable errors, but I will illustrate how to solve a problem such as this.
Explanation:
The speed of a wave is given by Speed = (Distance)/(Time), or, alternatively, Speed = Wavelength x Wave Frequency
In this problem, we are given a speed of "3 x 10 m/s." I suspect that the speed should have read 3x10^8 m/s, the speed of light. This says the speed is 30 m/s.
The frequency reads "998 x 10% H2." I can't guess what this was supposed to be, but 998 x 10% H2 means "99.8 H2." That doesn't seem to have anything to do with wavelength. Find the correct frequency, plug it into the equation with the correct speed, such as:
3x10^8 m/s = (9.98x10^2 cycles/sec)(Wavelength)
Wavelength = (3x10^8 m/s)/((9.98x10^2 cycles/sec) = 3.01x10^5 meters
Use the correct numbers, and you should be able to calculate the correct wavelength.
Answer:
<h2>To find the resultant force <u>subtract the magnitude of the smaller force from the magnitude of the larger force.</u> The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right, and a force of 3 N act to the left. Calculate the resultant force.</h2>
Physicists and astronomers conduct research to understand the nature of the universe and everything in it. These scientists observe, measure, interpret, and develop theories to explain celestial and physical phenomena using mathematics. From the vastness of space to the infinitesimal scale of subatomic particles, they study the fundamental properties of the natural world and apply the knowledge gained to design new technologies.
Upper mantle
The theory of the plate tectonics uses the convection cells in the upper mantle layer as the foundation for the movement of the continents.
To put it simple the process is explained like the convection cells create a lot of pressure, that pressure, supported by the high temperatures and magma, influence the crust above, and manage to crack it on certain places. As the crust cracks, it becomes a separate entity, and under the enormous force from bellow it slowly moves into a particular direction, and that is actually the movement of the tectonic plates.
Work done in moving a proton = potential difference×Charge of a proton
= 164×1.6×10⁻¹⁹ = 2.624×10⁻¹⁷ J
This work done should be equal to change in kinetic energy.
Initial speed of proton is zero therefore K.E initial will be zero.
Work done = final kinetic energy = 2.624×10⁻¹⁷ J
K.E = mv²/2
v² = 2(2.624×10⁻¹⁷)/1.6×10⁻²⁷ = 3.28×10¹⁰ m/s
∴ v = 1.811×10⁵ m/s
