Answer:

42.84

Explanation:

Let's take v_p to be the proton's velocity and v_e to be the electron's velocity and V to be the potential difference through which both the charges are accelerated  and further taking e  be the charge of proton and electron.

Using the given values:

m_p=1.67\times10^-^2^7kg\\\\m_e=9.1\times 10^{-31}kg

The expression for the work done is

W_p=W_e=eV

Solving for the kinetic energy equation:

W_p=W_e\\\\0.5m_pv_p^2=0.5m_ev_e^2\\\\\frac{v_e}{v_p}=\sqrt{\frac{m_p}{m_e}}\\\\=\sqrt{\frac{1.67\times10^{-27}}{9.1\times10^{-31}}}\\\\=42.83

Thus the  ratio ve/vp. ve/vp =42.84

Ber [7]

Answer:

Explanation:

One prolonged blast every two minutes is an indication of incoming of a power-driven vessel underway. This blast is done to make aware other boats, about your location, in the conditions of poor visibility. The other boats will have to slow down their speed, in order to avoid collision.

What is newton's third law second law first law ?​
sergeinik [125]

Answer:

first law: an object remains in uniform motion except an external force has acted upon it eg a ball in stable motion doesn't move until one moves or kicks it

second law:the body acted upon by an external force gains a momentum which is directly proportional to the applied force and acts in the direction of the force

third law: to every action there is an equal and opposite reaction eg if u push someone the person moves backward away from you and not towards you

Two identical metal spheres a and b are connected by a plastic rod. both are initially neutral. 1.0×1012 electrons are added to
Ann [662]
The plastic rod is made of insulator (plastic), so it does not allow charges moving from one sphere to another. This means that all the electrons given to sphere A will remain on sphere A.

The number of electrons initially given to sphere A is N=1.0 \cdot 10^{12}, and since the charge of 1 electron is e=-1.6 \cdot 10^{-19} C, the net charge left on sphere A after the removal of the rod will be
Q=N e = 1.0 \cdot 10^{12}(-1.6 \cdot 10^{-19} C)=-1.6.0 \cdot 10^{-7} C
