Answer:
the answer is c) 25.1 feet/second
Explanation:
because the blood droplets can not increase speed past terminal velocity 100.
Answer:
Magnitude = B = (μ₀*N*I /2R)
Direction= The direction of the magnetic field will be find out by the right hand rule. We will curve the finger of right hand in the direction of the current and our thumb will show the direction of the magnetic field. which will be out of the screen. That is + z direction.
From Gauss law we have
E = 2kx/r where x=linear charge density, r=distance from the wire=1.7 m
k =9 x 10^9 SI units.....we have been given E = 3.8 x 10^4 N/C ..... so plugging numbers we get
x = 3.59 x 10^ -6 C/ M (coulomb per meter) =linear charge density
The kinetic energy of the ball is given by:
where m=5 kg is the mass of the ball and v=2 m/s is its speed. Substituting these numbers, we find the kinetic energy:
Your body is pushing down on a chair because it is being attracted by gravity, the reason that your body is not moving down because there is a normal force acting on your body; together the net force of weight (m*g) and normal force is equal to zero
