Answer:

Yes when the velocity is constant then the acceleration is said to be zero. Thus an object with 0 acceleration can be in motion.

Let me give you an example to make you more clear

Example:

When a car is traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.

An electron is accelerqated in the uniform field betwen two parallel charged oplates. The separation of the plates is 1.20 cm

marysya [2.9K]

Answer:

The speed of electron is $8.7\times10^{6}\ m/s$

Explanation:

Given that,

Separation of the plate = 1.20 cm

Suppose the field is $E=1.80\times10^{4}\ N/C$ .

If the electron is accelerated from rest near the negative plate and passes through a tiny hole in the positive plate.

What the speed does it leave the hole?

We need to calculate the acceleration

Using formula of electric force

$F = qE$

$ma=qE$

$a=\dfrac{qE}{m}$

We need to calculate the speed of electron

Using equation of motion

$v^2=u^2+2as$

$v^2=2as$

Put the value of acceleration in the formula

$v^2=2\times\dfrac{qE}{m}\times s$

Put the value into the formula

$v^2=2\times\dfrac{1.6\times10^{-19}\times1.80\times10^{4}\times1.20\times10^{-2}}{9.11\times10^{-31}}$

$v=\sqrt{2\times\dfrac{1.6\times10^{-19}\times1.80\times10^{4}\times1.20\times10^{-2}}{9.11\times10^{-31}}}$

$v=8.7\times10^{6}\ m/s$

Hence, The speed of electron is $8.7\times10^{6}\ m/s$

Individuals suffering from somatoform disorders often see several doctors about their symptoms because doctors often refer their patients for a second opinion

<h3>What is doctors opinion?</h3>

Doctors usually ask people to take different medications to be able to treat the cause and the symptoms of a disease.

For example, they might prescribe antibiotics to treat the infection and anti-inflammatory medication for the swelling and pain.

According to this, the statement that says that doctors often advise a combination of treatments to eradicate an infection and treat symptoms is true.

Hence Individuals suffering from somatoform disorders often see several doctors about their symptoms because doctors often refer their patients for a second opinion
