Answer:
240m/s
Explanation:
The equation to calculate is wavelength= velocity/ frequency so to find the velocity you would have to multiply frequency by wavelength.
The law of superposition helps scientists determine the relative age of a layer of sedimentary rock. the law of superposition is <span>a basic </span>law<span> of geochronology, stating that in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on bottom, each layer being younger than the one beneath it and older than the one above it</span> .
hope this helps :)
Magnitude of displacement = 
Adding the squares gives displacement = 
Displacement =
≈ 724.7m
Answer:
The magnitude and direction of the magnetic field is 93.63 T in negative x direction.
Explanation:
Given;
speed of the electron in positive y direction, v = 2.0 x 10⁵ m/s
magnetic force on the electron, F in negative z direction = 3.0 x 10⁻¹² N
The magnitude of the magnetic force is given by;
F = Qv x B
B = F / Qv

The direction of the magnetic field is is as;
Based on the direction of magnetic force (negative z direction), the charge will be directed into negative y-direction because electron is negatively charged. Thus, the direction of the magnetic field will be in the negative x-direction

Therefore, the magnitude and direction of the magnetic field is 93.63 T in negative x direction.
“Yes, it is impossible to go around the curved path with zero acceleration. Acceleration is change in velocity. And velocity( speed+ direction) changes at every point in a curved path because there is change in direction at every point.”
