If the acceleration of a moving object is zero, the object remains at a constant speed (without friction)
Morgarella [4.7K]3 years ago

Answer:

Explanation:

According to the newton's second law, the force exerted on an object is equal to the product of the mass of the body and the acceleration of the body.

F = m x a

Where, F is the force and a be the acceleration and m be the mass of the body.

Acceleration is defined as the rate of change of velocity of the body.

As acceleration is zero, so

a = 0

v - u = 0

Where, v is the final velocity of the body and u be the initial velocity of the body.

It means the body is moving with uniform velocity.

what is the wavelength of waves at the beach if they have a frequency of 0.3 Hz and they move at 7.1 m/s?
Reil [10]

Answer:

23.67 m

Explanation:

We are given;

Frequency; f = 0.3 Hz

Speed; v = 7.1 m/s

Now, formula to get the wavelength is from the wave equation which is;

v = fλ

Where λ is wavelength

Making λ the subject, we have;

λ = v/f

λ = 7.1/0.3

λ = 23.67 m

Please help me. I don’t understand this.
guajiro [1.7K]

Answer:

Ft = 0[N]

Explanation:

To understand this problem we must perform an analysis of forces on the X axis, which coincides with the axis of forces of dogs.

In this way performing a sum of forces on the X-axis we will have (newton's third law):

F_{rigth}-F_{left}+F_{total} =0\\\  200-200+F_{total} =0\\F_{total}=0

From this analysis we can see that the resulting or total force is equal to zero, since there is no movement.

A deuteron particle consists of one proton and one neutron and has a mass of 3.34x10^-27 kg. A deuteron particle moving horizont
nikklg [1K]

_dThe radius of curvature of a subatomic particle under a magnetic field is given by the following formula:

r=\frac{mv}{qB}

Where:

\begin{gathered} r=\text{ radius} \\ v=\text{ velocity} \\ q=\text{ charge} \\ B=\text{ magnetic field} \end{gathered}

We can determine the quotient between the velocity and the charge of the deuteron particle from the formula. First, we divide both sides by the mass:

\frac{r_d}{m_d}=\frac{v}{q_B_}

Now, we multiply both sides by the magnetic field "B":

\frac{Br_d}{m_d}=\frac{v}{q}

Since the charge of the deuterion is the same as the charge of the proton and the velocity we are considering are the same this means that the quotient between velocity and charge is the same for both particles. Therefore, we can apply the formula for the radius again, this time for the proton:

r_p=\frac{m_pv}{qB}

And substitute the quotient between velocity and charge:

r_p=\frac{m_p}{B}(\frac{Br_d}{m_d})

Now, we cancel out the magnetic field:

r_p=\frac{m_pr_d}{m_d}

Now, we substitute the values:

r_p=\frac{(1.67\times10^{-27}kg)(0.385m)}{(3.34\times10^{-27}kg)}

Solving the operations:

r_p=0.193m=19.3cm

Therefore, the radius is 19.3 cm.
