AVprozaik [17]3 years ago
3 0

Answer:

0.2 Hz

Explanation:

Frequency: This can be defined as the number of circles completed by a wave in one seconds. The s.i unit is hertz.

From the question,

If 4 Waves arrives on the shore every 20 seconds,

Then,

x waves will arrives on the shore in one seconds

Solving for x

x = (4×1)/20

x = 0.2 Hz

Hence the frequency of the wave is 0.2 Hz

An electron moving in the direction of the +x-axis enters a magnetic field. If the electron experiences a magnetic deflection in
algol13

Answer:

- z axis

Explanation:

The magnetic force is perpendicular to its speed and the direction of the magnetic field, its equation being

      F = q v x B

Where the bold indicates vectors, q  is a positive charge,

The way to use this equation is with the rule of the right hand, the thumb points in the direction of the velocity, the other fingers extended in the direction of the magnetic field and the palm is the direction of the force for a positive charge.

Let's apply this to our case the speed is on the x axis and the force in ex. negative Y axis, the other fingers point perpendicular to the sheet, but since the charge is negative the magnetic field enters the sheet, this would be the negative z axis

A toy floats in a swimming pool. The buoyant force exerted on the toy depends on the volume ofa. none of these choices.b. all th
Citrus2011 [14]

Answer:c

Explanation:

The buoyancy force on toy depends upon the volume of toy under pool water.

According to Archimedes principle buoyant force on a floating body depends upon the weight of displaced liquid by object.

Buoyancy force is given by

F_b=\rho _f\times V\times g

where \rho _f=density of fluid

V=volume of object under water

g=acceleration due to gravity
