Positive ions from a base and negative ion from an acid form salt.

To add, table salt or common salt is a mineral composed primarily of sodium chloride, a chemical compound belonging to the larger class of salts. Rock salt or halite is also the common term for salt in its natural form.

Answer: Salt

Explanation:

When an acid reacts with the base then it undergoes neutralization to form a salt and water.

Acids are those substances which dissociate in the water to give $H^+$ ions.

$HX\rightarrow H^++X^-$

Bases are those substances which dissociate in the water to give $OH^-$ ions.

$BOH\rightarrow B^++OH^-$

The reaction of neutralization can be represented as,

$H^++X^-+B^++OH^-\rightarrow B^+X^-+H_2O$

where $BX$ is the salt formed.

$H^++Cl^-+Na^++OH^-\rightarrow Na^+Cl^-+H_2O$

A loop of area 0.250 m^2 is in a uniform 0.020 0-T magnetic field. If the flux through the loop is 3.83 × 10-3T· m2, what angle

dangina [55]

Answer:

40.0⁰

Explanation:

The formula for calculating the magnetic flux is expressed as:

$\phi = BAcos\theta$ where:

$\phi$ is the magnetic flux

B is the magnetic field

A is the cross sectional area

$\theta$ is the angle that the normal to the plane of the loop make with the direction of the magnetic field.

Given

A = 0.250m²

B = 0.020T

$\phi$ = 3.83 × 10⁻³T· m²

3.83 × 10⁻³ = 0.020*0.250cosθ

3.83 × 10⁻³ = 0.005cosθ

cosθ = 0.00383/0.005

cosθ = 0.766

θ = cos⁻¹0.766

θ = 40.0⁰

Hence the angle normal to the plane of the loop make with the direction of the magnetic field is 40.0⁰

In deep space, there is very little friction. Once they launch a probe into deep space, where there are no external forces actin

Charra [1.4K]

Answer:

move at constant velocity.

Explanation:

Newton's first law (also known as law of inertia) states that:

"when the net force acting on an object is zero, the object will keep its state of rest or if it is moving, it will continue moving at constant velocity".

In the case of the probe, friction in deep space is negligible, therefore when the engine is shut down, there are no more forces acting on the probe: the net force therefore will be zero, so the probe will move at constant velocity.

Answer:

The force required is 3,104 N

Explanation:

Force

According to the second Newton's law, the net force exerted by an external agent on an object of mass m is:

F = ma

Where a is the acceleration of the object.

On the other hand, the equations of the Kinematics describe the motion of the object by the equation:
