Explanation:
I know this because i just did it on study island
Answer:
3.0M
Explanation:
Thats two wavelengths,not one.
Pretty honest mistake I would've made the same if I was rushing
Answer:
Explanation:
Using:
Force = electric field * charge
Force = magnitude of charge * velocity * magnetic field * sin tither
Force on particle due to electric field:
Force on particle due to magnetic field:
is in the positive x direction as is in the negative x direction while net force is in the positive x direction.
Magnetic field is in the positive Z direction, net force is in the positive x direction.
According to right hand rule, Force acting on particle is perpendicular to the direction of magnetic field and velocity of particle. This would mean the force is along the y-axis. As this is a negatively charged particle, the direction of the velocity of the particle is reversed. Therefore velocity of particle, v, has to be in the negative y direction.
Now,
Answer:
The height of the building is approximately 156.58 m
Explanation:
The mass of the ball dropped from rest from the building top = 0.660 kg
The time in which the ball falls, t = 5.65 seconds
The height, h, of the building is given from the following equation of motion;
h = u·t + ¹/₂·g·t²
Where;
u = The initial velocity of the ball = 0 m/s
g = The acceleration due to gravity = 9.81 m/s²
Plugging in the values, we have;
h = 0 × 5.65 + ¹/₂ × 9.81 × 5.65² ≈ 156.58 m
The height of the building, h ≈ 156.58 m.
