A particle (q = 4.0 mC, m = 50 g) has a velocity of 25 m/s in the positive x direction when it first enters a region where the e

lectric field is uniform (60 N/C in the positive y direction). What is the speed of the particle 5.0 s after it enters this region?

Answer:

The speed of the particle is 34.66 m/s.

Explanation:

Given that,

Mass of particle = 50 g

Charge of particle = 4.0 mC

Velocity = 25 m/s

Electric field = 60 N/C

Time = 5.0 sec

We need to calculate the speed in y direction

Using formula of speed

v=a\times t

Where, a = acceleration

v=\dfrac{F}{m}\times t

v=\dfrac{qEt}{m}

Put the value in to the formula

v=\dfrac{4.0\times10^{-3}\times60\times5.0}{50\times10^{-3}}

v=24\ m/s

We need to calculate the speed of the particle

v=\sqrt{v_{x}^2+v_{y}^2}

Put the value into the formula

v=\sqrt{25^2+24^2}

v=34.66\ m/s

Hence, The speed of the particle is 34.66 m/s.

Answer:

In a primary cell, two electrodes (one of copper and other of zinc) of metal atoms are used. These electrodes are dipped in an electrolyte solution that causes the metals to produce their respective positive and negative ions.

In this way, the flow of charges takes place and supply the electricity to the source.

Unlike a primary cell, a dry cell contains paste of an electrolyte instead of the solution. The contents of electrolyte paste react with each other through a chemical process and convert the chemical energy into electrical energy.

How is our magnetic field made?
Grace [21]

Answer:

On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet. The magnetic field is extremely important to sustaining life on Earth.

Which of the following is NOT part of the kinetic theory of gases?
padilas [110]

Answer:

Option a

Explanation:

The three basic and major points of the kinetic theory of gases are listed below:

1. In the collision between the gas molecules, no loss or gain of energy takes place.

2. According to the theory, the gaseous molecules exhibits constant and linear motion.

3. The molecules of the gas occupies very little space as compared to the container. Thus the empty space in a gas is not very little.

If the same elevator accelerates downwards
PilotLPTM [1.2K]

The upward force exerted by the elevator floor on the passenger is 7.6 times mass of the passenger.

<h3>What is force?</h3>

A force in physics is an effect that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

Given in question elevator accelerates downwards with an acceleration of 1.2 m/s². There is acceleration due to gravity working downward which is 9.8 m/s².

So, net acceleration due to gravity is given as 9.8 - 1.2 = 7.6 m/s²

The upward force exerted by the elevator floor on the passenger is mass times acceleration, 7.6 times mass of passenger.
