Answer:

1.17

Explanation:

Given that,

The refractive index of rock salt with respect to water is 1.17.

We need to find the refractive index of water with respect to rock salt.

We know that,

Refractive index = (speed of light in air or vaccum)/( speed of light in that medium)

Refractive index of rock salt with respect to ice = (speed of light in ice)/(speed of light in rock salt)

The speed of light in ice = c/1.31

The speed of light in rock salt = c/1.54

Required refractive index,

[tex]\mu=\dfrac{1.54}{1.31}\\\\=1.17[/tex]

So, the refractive index of water with respect to rock salt is equal to 1.17.

Answer: A shunt is a low-ohm resistor that can be used to measure current. ... The entire current flows through the shunt and generates a voltage drop, which is then is measured. Using Ohm's law and the known resistance, this measurement can then be used to calculate the current (I = V/R).

Answer:

The force of repulsion is 17.802 N

Explanation:

Given;

magnitude of the first charge, q₁ = 8.6 x 10⁻⁶ C

magnitude of the second charge, q₂ = 2.3 x 10⁻⁴ C

distance between the two charges, r = 1 m

The force of repulsion is calculated using Coulomb's law;

[tex]F = \frac{Kq_1q_2}{r^2} \\\\F = \frac{9\times 10^9 \times 8.6\times 10^{-6} \times 2.3\times 10^{-4}}{1^2} \\\\F = 17.802 \ N[/tex]

Therefore, the force of repulsion is 17.802 N

Answer:

He is incorrect. Dissolving salt in water and evaporation of the water are both physical changes. The reappearance of salt is evidence that the change was reversible by a physical change, so it could not be a chemical change.

Answer:

The correct answer is - transform boundary; plates slide past one another in opposite directions causing the formation of faults and earthquakes.

Explanation:

If the continental or oceanic plates slide past one another either in the same direction or in opposition direction forms the transform fault boundary. Due to this tectonic plate formation, no new crust is formed or subducted, but earthquake activities forms.

Convergent boundaries forms by pushing the edge of one plate underneath the other while coming together whereas plates move away from one another causing rift valleys called divergent boundary.

The sketch of the two cases has been attached to this response.

Case 1: The box is pushed by a horizontal force F making it to move with constant velocity.

In this case, a frictional force [tex]F_{r}[/tex] is opposing the movement of the box. As shown in the diagram, it can be deduced from Newton's law of motion that;

∑F = ma    -------------------(i)

Where;

∑F = effective force acting on the object (box)

m = mass of the object

a = acceleration of the object

∑F = F -  [tex]F_{r}[/tex]

m = 50kg

a = 0   [At constant velocity, acceleration is zero]

Substitute these values into equation (i) as follows;

F -  [tex]F_{r}[/tex] = m x a

F -  [tex]F_{r}[/tex] = 50 x 0

F -  [tex]F_{r}[/tex] = 0

F =  [tex]F_{r}[/tex]            -------------------(ii)

Case 2: The box is pushed by a horizontal force 1.5F making it to move with a constant velocity of 0.1m/s²

In this case, the same frictional force [tex]F_{r}[/tex] is opposing the movement of the box.

∑F = 1.5F -  [tex]F_{r}[/tex]

m = 50kg

a =  0.1m/s²

Substitute these values into equation (i) as follows;

1.5F -  [tex]F_{r}[/tex] = m x a

1.5F -  [tex]F_{r}[/tex] = 50 x 0.1

1.5F -  [tex]F_{r}[/tex] = 5            ---------------------(iii)

Substitute [tex]F_{r}[/tex] = F from equation (ii) into equation (iii) as follows;

1.5F - F = 5            

0.5F = 5            

F = 5 / 0.5

F = 10N

Therefore, the value of F is 10N

Answer:

Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size.Matter can exist in several states, also called phases. The three most common states are known as solid, liquid and gas.Matter is the Stuff Around You or Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume).Solid ice, water and steam are few examples of matter touched in everyday life. Subatomic particles are also considered as matter.

Answer:

But where are the graphs

Coulomb's Law describes the relationship between electromagnetic force and the distance between charges.

The relationship between electromagnetic force and the distance between charges is described by Coulomb's Law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Mathematically, Coulomb's Law is expressed as:

F = k  (q₁x q₂) / r²

where F is the electromagnetic force, q1 and q2 are the charges, r is the distance between the charges, and k is the Coulomb constant.

This means that as the distance between two charges increases, the force between them decreases, and as the distance decreases, the force increases. The relationship between force and distance is inverse square, which means that the force decreases rapidly as the distance increases.

Answer:

c. 0.02 C and 4 J

Explanation:

Applying,

Q = CV................ Equation 1

Where Q = Charge, C = Capacitance of the capacitor, V = Voltage.

From the question,

Given: C = 50 μF = 50×10⁻⁶ F, V = 400 V

Substitute these values into equation 1

Q = (50×10⁻⁶)(400)

Q = 0.02 C.

Also Applying

E = CV²/2............. Equation 2

Where E = Energy stored.

Therefore,

E = (50×10⁻⁶ )(400²)/2

E = 4 J

Hence the right option is c. 0.02 C and 4 J

Explanation:

As acceleration is the rate of change of velocity with time, if velocity is uniform, there will be no change in it and acceleration will be zero.

Answer:

5 m/s

Explanation:

As the ball falls to the ground, it is acted upon by a force which is due to the gravitational force. Hence, the ball falls with an acceleration called the acceleration due to gravity.

Let us assume that the acceleration due to gravity (g) = 10 m/s², Since initially, the body was at rest, hence the initial velocity (u) = 0 m/s. The height to the ground (h) = 1.3 m. Hence using the equation of motion, the final velocity (v) is:

v² = u² + 2gh

Substituting:

v² = 0² + 2(10)(1.3)

v² = 26

v = √26 = 5

v = 5 m/s

Answer:

220 N

Explanation:

When a shopping cart rolls into a parked car on the street, it hits the car with a force of 220 newtons.

We need to find the force the shopping cart experiences from the car.

We know that, Newton's third law of motion states that for every action there is an equal and opposite reaction.

Hence, the shopping cart experiences a force of 220 N from the car.
