Answer:

Velocity of proton will be equal to 4500 m/sec

Explanation:

We have given that proton moves right angles through a magnetic field

So angle between magnetic field and velocity of proton is \Theta =90^{\circ}

Magnetic field B = 0.025 Tesla

Charge on proton e=1.6\times 10^{-16}C

Magnetic force on the proton is given F=1.8\times 10^{-14}N

Magnetic force on a moving charge particle is equal to F=qvBsin\Theta

So 1.8\times 10^{-14}=1.6\times 10^{-16}\times v\times 0.025\times sin90^{\circ}

v = 4500 m/sec

So velocity of proton will be equal to 4500 m/sec

A 75 kg man and a 100. Kg woman are playing tug of war on a frictionless surface. The man accelerates toward the woman at 2.0 m/
Artemon [7]

Complete Question

A 75 kg man and a 100. Kg woman are playing tug of war on a frictionless surface. The man accelerates toward the woman at 2.0 m/s2.How much force does she use to pull on the rope

Answer:

The value is  F  =  150 \  N

Explanation:

From the question we are told that

    The mass of the man is  m_m   =  75 \  kg

     The mass of the woman is  m_f  =  100 \  kg

     The acceleration of the man is  a_m  =  2.0 \  m/s ^2

Generally the force which she used to pull the rope is mathematically represented as  

           F  =  m  *  a

=>         F  =  75 *  2

=>         F  =  150 \  N

At what displacement of a sho is the energy half kinetic and half potential?
Illusion [34]

Answer:

Displacement = 0.707A

Explanation:

To solve for the displacement we know that

Potential energy PE = 1/2Total energy (Etotal)

Therefore 1/2kx^2 = 1/2(1/2KA^2)

Solving for x we have

x^2 = √A^2/2

x = A/√2

x= 0.707A
