Explanation:

Given;

density of water, ρ = 1.0 g/cm³

volume of the submerged block, V = 120 cm³

Applying Archimedes principle;

The mass of the liquid displaced is calculated as;

m = ρV

m = 1.0 g/cm³ x 120 cm³

m = 120 g

m = 0.12 kg

The buoyant force on the block is calculated as;

F = mg

F = 0.12 x 9.8

F = 1.176 N

Therefore, the buoyant force on the block is 1.176 N.

Explanation:

a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.

Answer:

Electromagnetic field can be produced by the superposition of electric field and magnetic field.

Explanation:

When two or waves propagate in a medium without affecting each other , then at any instant the displacement of a particle will be equal to the vectorial sum of the displacements due to the waves.

Hence Electromagnetic field can be produced by L-C CIRCUITS.

Explanation:

The torque on the bar will be - 13.26 Nm. And the sign of the direction of the figure will be inside the plane.

Torque is the rotating counterpart of force in physics and mechanics. The instant of force is another name for it. It illustrates how a force can cause a change in the body's rotational movement.

Let 'F' be the force and 'r' be the distance.

The torque is the vector product of the force and radius which is given as,

T = r x F

T = r · F · sin θ

A 25N power is applied to a bar that can turn around its end. The power is r = 0.75 m away from the finish of a point at θ = 45°.

Then the torque is calculated as,

T = - 0.75 x 25 x sin 45°

T = - 13.26 Nm

The sign of the direction of the figure will be inside the plane.

Answer:

Water pollution can come from the remains of dead organic matter or animal waste in waterways.

Answer:

A.) They will repel, moving in opposite directions at the same speed.

Explanation:

The correct option is - A.) They will repel, moving in opposite directions at the same speed.

As because the two balloons have identical charge and moving towards each other , so they repel each other (as we know like charges repel each other)

Option A is correct. (A.) They will repel, moving in opposite directions at the same speed. Because the megnitude and nature of the charge are same.

The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Charges that are similar repel each other, whereas charges that are diametrically opposed attract each other.

They will repel, moving in opposite directions at the same speed. Because the megnitude and nature of the charge are same.

Hence option A is correct. (A.) They will repel, moving in opposite directions at the same speed.

Answer:

69.28 m/s

Explanation:

From the question given above, the following data were obtained:

Power = 400 Watt

Time (t) = 10 minutes

Mass (m) = 100 Kg

Velocity (v) =?

Next, we shall convert 10 mins to seconds (s). This can be obtained as follow:

1 min = 60 s

Therefore,

10 mins = 10 × 60

10 mins = 600 s

Next, we shall determine the energy. This can be obtained as follow:

Power = 400 Watt

Time (t) = 600 s

Energy (E) =?

E = Pt

E = 400 × 600

E = 240000 J

Finally, we shall determine how fast the cart is moving. This can be obtained as illustrated below:

Mass (m) = 100 Kg

Energy (E) = Kinetic energy (KE) = 240000 J

Velocity (v) =?

KE = ½mv²

240000 = ½ × 100 × v²

240000 = 50 × v²

Divide both side by 50

v² = 240000 / 50

v² = 4800

Take the square root of both side

v = √4800

v = 69.28 m/s

Thus, the cart is moving with a speed of 69.28 m/s

The international system of units otherwisely known as SI is widely used and accepted all over the globe while English system of measurement is only used by the British this limits their usage as it is applied in few part of the world which is Britain.

Both units are form of measurement being used for evaluating measurement

Explanation:

Answer:Both systems are used to numerically describe measurement. The SI system is based on the number 10 as well as multiples and products of 10. This makes it much easier to use, and so it has been the accepted system in scientific and technical applications

Explanation:The English system is more complicated as relationships between units of the same quantity aren’t uniform.

Answer:

Total distance traveled = 9 m

Explanation:

Given:

Distance travel towards north = 3 meter

Distance travel towards south = 6 meter

Find:

Total distance traveled

Computation:

Total distance traveled = Sum of total distance

Total distance traveled = Distance travel towards north + Distance travel towards south

Total distance traveled = 3 m + 6 m

Total distance traveled = 9 m

Answer:

Please see below as the answer is self-explanatory.

Explanation:

Answer:

10 and 5

Explanation:

Answer:

It is given that,

Force, F = 30 pounds = 133.4 N

Distance, d = 15 feet = 4.572 m

Time taken, t = 3 minutes = 180 seconds

Lucas's speed is given by the ratio of total displacement divided by total time taken. It is given by :

s = 0.0254 m/s

So, her speed is 0.0254 m/s.

Work done, W = F . d

W = 133.4 N × 4.572 m

W = 609.90 J

or

W = 610 J

Hence, this is the required solution.

1. The equivalent resistance in a series circuit, like the one shown, is given by the general equation

[tex]R_{S} = R_1 + R_2 + R_3 + . . . + R_{N-1} + R_N = \sum_{i=1}^N R_i[/tex]

where N is the number of resistors in series. Here, there are four resistors in series. Using our equation with N = 4, we obtain

[tex]R_{S} &= R_1 + R_2 + R_3 + R_4 \\ R_{S} = 2.0 \, \Omega + 3.0 \, \Omega + 4.0 \, \Omega + 6.0 \, \Omega \\ R_{S} = 15.0 \, \Omega.[/tex]

2. The current in this series circuit is equal to the voltage divided by the equivalent resistance (a relationship you can derive from Ohm's law):

[tex]I = \frac{V}{R_{S}} = \frac{45 \, V}{15.0 \, \Omega} = 3.0 \, A. \nonumber[/tex]
