Explanation:

W = M . G

W = 60 . 10

W = 600

When vector A is oriented in the same direction as vector B, the resultant's greatest magnitude is A + B = 12 + 8 = 20 units. When vector A is oriented in the direction opposite to vector B, the resultant vector has its least magnitude, A - B = 12 - 8 = 4 units.

A vector that produces the aggregate impact of all other vectors is known as a resultant vector. The resultant vector is what we get when we combine two or more vectors. The head-to-tail convention, which is defined as "joining the tail of the first vector with the head of the second vector to give another vector whose head is joined with the head of the second vector and tail of the first vector," can be used to geometrically add vectors by drawing them on a common scale.

Any number of vectors can be added by extending the procedures for obtaining a vector's resultant or adding more than two vectors.

R=A+B+C---

Assume there are three vectors: A, B, and C. These vectors must be drawn in accordance with the head-to-tail rule so that the heads of each vector line up. As a result, the resultant vector is as follows:

R=A+B+C

By angular speed, the frequency is 2.39 Hz.

We need to know about the angular speed of harmonic oscillation. the angular speed can be determined as

ω² = k / m

where ω is angular speed, k is spring constant,  and m is the mass.

The angular speed can be calculated by

ω = 2πf

Hence,

ω² = k / m

(2πf)² = k / m

k = (2πf)² / m

where f is frequency.

From the question above, we know that:

m1 = 0.6 kg

f1 = 3 Hz

m2 = 0.38 kg

The spring is same, hence the spring constant is the same

k1 = k2

(2πf1)² / m1 = (2πf2)² / m2

f1² / m1 = f2² / m2

3² / 0.6 = f2² / 0.38

f2² = 5.7

f2 = 2.39 Hz

Explanation:

The capacitance value of a capacitor is measured in farads (F)

The SI unit for capacitance is referred to as Farads.

This is the ability of a device or circuit to store energy which is usually in

the form  of electric charges.

A capacitor on the other hand is the device which performs this function.

The formula for determining capacitance is denoted below:

C = q/V where C is capacitance, q is charges and V is voltage.

Answer:

(a) 180 km

(b) 30km

Explanation:

To find displacement (in this case, kilometers) you need to convert km/h to km, this can be done by multiplying by the amount of hours:

[tex]\frac{60km}{h}*3h=60km*3=180km \\\frac{60km}{h} *h/2 = 60km/2=30km[/tex]

(The h/2 term came from 1/2*h, since half an hour is h*1/2)

The step down transformer decrease the incoming current's voltage.

Transformers go with the principle of mutual inductance . A changing magnetic field in one circle of wire actuates an electromotive force (EMF) in an adjoining circle of wire, inductively coupled to the primary. In exceptionally fundamental terms, a transformer comprises two coils of wire with tall shared inductance. These coils are electrically isolated whereas they share a common magnetic circuit. In a step-down transformer, there is a decrease in the incoming current’s voltage, where the primary voltage is the incoming voltage whereas the outgoing voltage is considered the secondary. the second coil has fewer windings than the primary, permitting a decrease in voltage within the exiting electrical stream. The primary winding, which is the primary set of coils, interfaces to an alternating-current voltage source, or primary voltage influx. The secondary coil interfaces to the stack, or secondary voltage outpouring, conveying the electrical control absent from the transformer. The substituting current streaming in at the primary voltage makes a substituting magnetic flux. This actuates a similar current within the secondary coil, making a secondary voltage. Here, the diminished number of windings within the secondary coil successfully diminishes the resultant voltage, subsequently “stepping down” the voltage to a lower value whereas keeping up a steady frequency.

The magnetic influence on moving electric charges, electric currents and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field. The magnetic field of a permanent magnet pulls on ferromagnetic substances like iron and attracts or repels other magnets. A magnetic field that varies with location will also exert a force on a variety of non-magnetic materials by changing the velocity of those particles' outer electrons.

"Consciousness is everything.  Consciousness and "conscious" are catch-all terms that refer to a wide range of mental events. Both have a variety of connotations, and the word "conscious" is used to describe both specific mental states and processes (state consciousness) as well as entire creatures (creature consciousness).

Your distinctive awareness of your own thoughts, memories, emotions, sensations, and surrounds is what is known as consciousness. Being aware of oneself and one's surroundings is the essence of consciousness.

The electric field at the surface of the cylinder is 51428V/m

Given data:

• The length of the charge is l=  7m.

• The charge is q = 2μC..

• The radius the cylinder is r = 10 cm

Since the filament length is so large as compared to the cylinder length that the infinite line of charge can be assumed.

The expression to calculate the electric field is given as,

E=2kλ/r

Here, λ is the linear charge density.

Substitute the values in the above equation,

E = (2×9×109N⋅m^2/C^2×2×10^−6C)/0.1m×7m

E = 51428N/C×(V/m)/(N/C)

=51428V/m

An electric charge is the property of matter where it has more or fewer electrons than protons in its atoms. Electrons carry a negative charge and protons carry a positive charge.

B. The surface of the Earth heats the air that contacts it.

Explanation:

Conduction is a mode of heat transfer in which energy is transferred from a hot molecule to the neighboring molecules due to contact. Thus, heat energy is transferred from one molecule to another in the process.

Therefore, the air that comes in contact with the surface of the earth heats up by conduction. Since the surface of the earth is heated up due to the radiation from the Sun.

Answer:

Black bodies are good absorber of light waves from the sun, while shining surfaces are good reflector of the light waves.

Explanation:

Generally, a black surface or material tends to absorb light waves while under the sun, while a shiny surface is a good reflector of the waves. This is because the black material is a good absorber, and also a good emitter.

The shiny necklace can only absorb little light waves from the sun, thus it reflects most of the light waves. The reflection is the reason for the small circles of light seen around the yard.

However, when in a cool environment the black shirt would cools faster (good emitter) than the shiny necklace.
