Answer:

As we know that liquid pressure is depend upon the depth of liquid where the downstair tap has more depth so water come out with more pressure wheres the upstairs tap has less depth so water come out with low pressure so

Coulomb's law for the magnitude of the force F between two particles with charges Q and Q′ separated by a distance d is

romanna [79]

Answer:

The net force exerted by the two charges is 10.97 x 10⁻⁵ N along negative x-direction.

Explanation:

K=1/4πϵ0, where ϵ0=8.854×10−12C2

K = 9x10⁹

The electric force on point charge q₃ due to charge q₂ is

F₃₂ = kq₃q₂ / (1.245)²

= (9x10⁹ * 49.5x10⁻⁹ * 30.5x10⁻⁹) / (1.245)²

= 13,587.75 x 10⁻⁹ / 1.55

= 8.76629 x 10⁻⁵ N

The electric force on point charge q₃ due to charge q₁ is

F₃₁ = kq₃q₁ / (1.695 - 1.245)²

= (9x10⁹ * 49.5x10⁻⁹ * 10.0x10⁻⁹) / 0.2025

= 2.2000 x 10⁻⁵ N

The net electric force on point charge q₃ is

F₃ = -F₃₁ - F₃₂

= - 8.76629 x 10⁻⁵ N - 2.2000 x 10⁻⁵ N

= 10.97 x 10⁻⁵ N along negative x-direction

Answer:

A) Momentum is always conserved, and kinetic energy may be conserved. TRUE

(B) Kinetic energy is always conserved, and momentum may be conserved. FALSE

(C) Momentum is always conserved, and kinetic energy is never conserved. FALSE

(D) Both momentum and kinetic energy are always conserved.

FALSE

(E) Neither momentum nor kinetic energy is conserved.

FALSE

Explanation:

A) Momentum is always conserved, and kinetic energy may be conserved.

Always the momentum is conserved for any collision.

(B) Kinetic energy is always conserved, and momentum may be conserved.

In inelastic collison the Kinetic energy is not conserved.

(C) Momentum is always conserved, and kinetic energy is never conserved.

For elastic collision the kinetic energy is always conserved.

(D) Both momentum and kinetic energy are always conserved.

The kinetic energy never is conserved in an inelastic collision.

(E) Neither momentum nor kinetic energy is conserved.

The momentum always is conserved.

Answer:

a) The magnitude of the magnetic field = 7.1 mT

b) The direction of the magnetic field is the +z direction.

Explanation:

The force, F on a current carrying wire of current I, and length, L, that passes through a magnetic field B at an angle θ to the flow of current is given by

F = (B)(I)(L) sin θ

F/L = (B)(I) sin θ

For this question,

(F/L) = 0.113 N/m

B = ?

I = 16.0 A

θ = 90°

0.113 = B × 16 × sin 90°

B = 0.113/16 = 0.0071 T = 7.1 mT

b) The direction of the magnetic field will be found using the right hand rule.

The right hand rule uses the first three fingers on the right hand (the thumb, the pointing finger and the middle finger) and it predicts correctly that for current carrying wires, the thumb is in the direction the wire is pushed (direction of the force; -y direction), the pointing finger is in the direction the current is flowing (+x direction), and the middle finger is in the direction of the magnetic field (hence, +z direction).
