This dude was sitting in the chair. Someone pulls the chair out from under him. He does not move in the direction of the chair.

He simply falls to the ground in the same spot he was sitting. This shows inertia because:

Answer:

This shows inertia because inertia is an object's resistance to change in motion. When the person (imma call them a she) who pulled the chair from under the guy did that, the chair was the one affected by the force of the girl, not the guy. The guy continued heading in the direction he was originally going, which was down.

At least, that's about how I would answer this question.

What is the momentum of a 3kg ball that is traveling at 5m/s
marta [7]

Answer:

15 Kg m/s

Explanation:

momentum p = mv

p is momentum

m is mass (kg)

v is velocity (m/s)

p = (3) (5m/s)

p= 15 Kg m/s

A liquid of density 1288 kg/m3 flows with speed 2.88m/s into a pipe of diameter 0.24 m. The diameter of the pipe decreases to 0.
Tju [1.3M]

Answer:

66.35m/s

Explanation:

Para resolver el ejercicio es necesario la aplicación de las ecuaciones de continuidad, que expresan que

A_1V_1 =A_2 V_2

From our given data we can lower than:

R_i = \frac{0.24}{2} = 0.12m

R_f = \frac{0.05}{2} = 0.025m

So using the continuity equation we have

A_1V_1 =A_2 V_2

V_2 = \frac{A_1V_1}{A_2}

V_2 = \frac{(\pi(0.12^2))(2.88)}{(\pi (0.25)^2)}

V_2 = 66.35m/s

Therefore the velocity at the exit end is  66.35m/s

An electric field of 2.09 kV/m and a magnetic field of 0.358 T act on a moving electron to produce no net force. If the fields a
My name is Ann [436]

Answer:

The velocity is  v =  5838 \ m/s

Explanation:

From the question we are told that

   The electric field is E  =  2.09 kV/m =  2.09 *10^{3} \ V/m

    The magnetic field is  B  =  0.358 \ T

     

Generally the force experienced by the electron due to the magnetic field is

         F_m  =  qvB

Generally the force experienced by the electron due to the electric  field is

       F_e =  qE

Since from the question the net force is zero  then

     F_e =  F_m

=>    v =  \frac{E}{B}

Substituting values

      v =  \frac{2.09*10^{3}}{0.358 }

    v =  5838 \ m/s
