Answer:

C

Explanation:

Options A and B are not even pointing in the direction as the vectors in the question so they shouldn't even be considered.

Option C looks like the closes since vectors A and B are pointing in a similar direction (negative x-axis)

The best representation for the resultant vector representing the resultant R=A+B would be option C because the result is represented by the closing side of the triangle, therefore the correct answer would be C.

The quantities that contain the magnitude of the quantities along with the direction are known as the vector quantities.

Examples of vector quantities are displacement, velocity acceleration, force, etc.

As given in the problem we have to find out the resultant vector from the sum of vector A and vector B,

The resultant of the vector can be calculated with the help of the triangle law of the vector addition in which the sum is given by the closing side of the triangle.

Thus, the correct answer is option C.

Answer:

An elastic collision is a collision in which there is no net loss in kinetic energy in the system as a result of the collision. Both momentum and kinetic energy are conserved quantities in elastic collisions.

Suppose two similar trolleys are traveling toward each other with equal speed. They collide, bouncing off each other with no loss in speed. This collision is perfectly elastic because no energy has been lost.

In reality, examples of perfectly elastic collisions are not part of our everyday experience. Some collisions between atoms in gases are examples of perfectly elastic collisions. However, there are some examples of collisions in mechanics where the energy lost can be negligible. These collisions can be considered elastic, even though they are not perfectly elastic. Collisions of rigid billiard balls or the balls in a Newton's cradle are two such examples.

Answer: 1600 km from the surface

Explanation:

\(E = \frac{GM}{R^{2} }\\g1 = \frac{GM}{R1^{2} } \\R1 = 6400 km\\g2 = 0.64g1\\\frac{g1}{g2} = \frac{\frac{GM}{R1^{2} } }{\frac{GM}{R2^{2} } } \\\frac{g1}{0.64g1} = \frac{R2^{2}}{R1^{2} }\\\frac{1}{0.64} = \frac{R2^{2}}{6400^{2} }\\\\\frac{1}{0.8} = \frac{R2}{6400}\\\\R2 = \frac{6400}{0.8}\\R2 = 8000 km\\\)

Therefore, 8000 km - 6400 km = 1600 km from the surface

W = -mgytotal = -mgh is the total work performed by the gravitational force. Ug = mgh represents the change in potential energy. A potential energy function depends on an object's position.

By taking the derivative of the potential, the force at every place may be determined if the potential energy function U(x) is known. This indicates graphically that if we have potential energy vs. position.

Potential energy and equilibrium are related in that in an equilibrium like this, the body's potential energy is lower. In this case, when the body is moved a short distance, the state generates a force that does not oppose the movement.

Given:

The phenomenon of beats occurs when tuning two musical instruments

To find:

The reason

Explanation:

Two waves with nearly the same frequencies and same amplitudes superimposed with each other produce beats. If an instrument is sounded against a standard frequency and tuned until the beats disappear then the instrument is in tune with the standard frequency. The tones interfere constructively and destructively with each other.

Hence, the second option is the correct one.

The distance travelled by the object between 5 and 10 seconds is 25 m.

The area under velocity time graph gives the distance travelled by the object.

The distance travelled by the object between 5 and 10 seconds is calculated from the area of curve within this time range.

Area of the curve between 5 and 10 seconds = Area of triangle

Distance travelled between 5 and 10 seconds = Area of triangle formed between 5 and 10 seconds

Area of triangle = ¹/₂bh

The amount of energy of a single photon of light is determined by its frequency.

The Planck-Einstein relation is a fundamental equation that describes the relationship between the energy (E) of a single photon of light and its frequency (f). The relation is given by the formula:

\(E = hf\)

where h is Planck's constant, a physical constant with a value of approximately \(6.626 x 10^-34 joule seconds (Js)\). This equation suggests that the energy of a photon is directly proportional to its frequency. In other words, photons with higher frequencies (such as those in the ultraviolet or x-ray parts of the electromagnetic spectrum) have more energy than those with lower frequencies \(6.626 x 10^-34 joule seconds (Js)\) (such as those in the infrared or radio parts of the spectrum).

The speed of the photon and the material it moves through can affect its wavelength and therefore its frequency, but they do not directly determine its energy. The time it takes the photon to reach a destination is not directly related to its energy either.

Answer:

Explanation:

a ) Restoring force in special spring F = k x³

let it is stretched by length l and it is further stretched by dl .

work done on spring in stretching by dl

= F dl

= k l³ dl

work done in stretching by A

= ∫k l³ dl between limit 0 to A

= k [ l⁴ / 4 ] between limit 0 to A

= k A⁴ / 4 ;

b )

Let v be the maximum speed attained ,

kinetic energy of mass = potential energy of spring

1/2 M v² = k A⁴ / 4

v² = kA⁴ / 2

v = A² √( k/2 )

c ) Let the required displacement be d .

potential energy = k d⁴ / 4

at displacement d , potential energy and kinetic energy are equal so potential energy = 1 /2 of total potential energy = 1/2 x k A⁴ / 4

= k A⁴ / 8

So

k A⁴ / 8  = k d⁴ / 4

\(d = A\times ( \frac{1}{2} )^\frac{1}{4}\)

The magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹ (Option E).

The electric flux through a surface is given by the product of the electric field strength and the area of the surface projected perpendicular to the electric field.

In this case, the electric field strength is 18 N C⁻¹, and the area of the sheet projected perpendicular to the electric field is 0.450 m²

(since the normal to the sheet makes an angle of 60° with the electric field). Multiplying these values gives the electric flux:

Electric flux = Electric field strength × Area

Electric flux = 18 N C⁻¹ × 0.450 m²

Electric flux = 8.1 N m² C⁻¹

In summary, the magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹. This value is obtained by multiplying the given electric field strength by the projected area of the sheet perpendicular to the electric field.

The angle of 60° is taken into account to determine the effective area for calculating the flux.(Option E).

Electricity

Energy transfer is the movement of energy from one point to another. This can be heat energy, kinetic energy, etc.

There are three forms of energy transfer, namely:

Conduction

Convection

Radiation

Conduction is the transfer of heat energy in which there is no actual movement of the molecules involved. This usually happens in solid materials

Convection is the transfer of energy in fluids. This involves the movement of the molecules through which the energy is transferred.

Radiation is the transfer of energy in which no material is involved.

Note that electricity only involves the movement of charges, it is not a mode of energy transfer.

Answer:

 t ’= \(\frac{1450}{0.6499 + 2 v_r}\),  v_r = 1 m/s       t ’= 547.19 s

Explanation:

This is a relative velocity exercise in a dimesion, since the river and the boat are going in the same direction.

By the time the boat goes up the river

        v_b - v_r = d / t

By the time the boat goes down the river

        v_b + v_r = d '/ t'

let's subtract the equations

       2 v_r = d ’/ t’ - d / t

       d ’/ t’ = 2v_r + d / t

       \(t' = \frac{d'}{ \frac{d}{t}+ 2 v_r }\)

In the exercise they tell us

         d = 1.22 +1.45 = 2.67 km= 2.67 10³ m

         d ’= 1.45 km= 1.45 1.³ m

at time t = 69.1 min (60 s / 1min) = 4146 s

the speed of river is v_r

      t ’= \(\frac{1.45 \ 10^3}{ \frac{ 2670}{4146} \ + 2 \ v_r}\)

      t ’= \(\frac{1450}{0.6499 + 2 v_r}\)

In order to complete the calculation, we must assume a river speed

          v_r = 1 m / s

let's calculate

      t ’= \(\frac{ 1450}{ 0.6499 + 2 \ 1}\)

      t ’= 547.19 s
