Answer:

the new frequency is : 302.25Hz

using the formula F2 = \(\frac{F1 L1}{L2}\)

Explanation:

frequency of a string is the number of vibrations of a plucked string per second. it is measured in Hertz.

the frequency of a string is inversely proportional to twice the length of the string. which means the longer the string, the smaller the freqency and the higher the string the higher the frequency.

f ∝ 1/2L.

f = k/2L

where f = frequency

                         L = length of string

                         k = constant

k = 2fL is a constant

given data

L1 = 0.62m

f1 = 234Hz

L2 = 0.48m

2f1L1 = 2f2L2

f1L1 = f2L2

f2 = f1L1/L2

f2 = \(\frac{234 x 0.62}{0.48}\) = 302.25Hz

in conclusion, the new frequency is 302.25Hz

(a) The acceleration of the electron due to the field a= 3.5*10^(15) m/s^2

(b) The speed of the electron will be v=17.5*10^(5) m/s

Acceleration is defined as the change of the velocity with the time. Acceleration is a vector quantity and is defined by both the magnitude and the direction.

We know that the force act on the electron in the electric field is given as

F=qE=ma

Here,

q= charge on electron = 1.6*10^-19 C

E = Electric field = 2*10^4 N/m

m= Mass of electron= 9.1*10^-31 kg

a= acceleration of electron

(a) The acceleration can be given as:

\(a=\dfrac{qE}{m}\)

\(a=\dfrac{1.6\times 10^{-19}\times 2\times 10^{4}}{9.1\times 10^{-31}}\)

\(a=3.5\times 10^{15}\ \frac{m}{s}\)

(b) The velocity of the electron will be given as

v= final velocity

u=initial velocity=0

t= time suppose=5 sec

Now from the formula

v=u+at

\(v=0+3.5\times 10^{15} \times 5\)

\(v=17.5\times 10^{15}\ \dfrac{m}{s}\)

Hence

(a) The acceleration of the electron due to the field a= 3.5*10^(15) m/s^2

(b) The speed of the electron will be v=17.5*10^(5) m/s

The electric field at point B, located at the midpoint between the upper left and right corners of the square, can be approximated as 3.244 x \(10^6\) N/C in the upward direction.

To find the electric field at point B, we can consider the contributions from the two charges placed at the lower corners of the square. Since the charges are the same and the distance to point B is the same for both charges, the magnitudes of the electric fields produced by each charge will be equal.

First, let's calculate the magnitude of the electric field produced by one of the charges at point B using Coulomb's Law:

Electric field due to a point charge (E) = (k * q) / \(r^2\)

Where:

- k is the electrostatic constant, approximately equal to 8.99 x 10^9 \(10^9\)N \(m^2/C^2\)

- q is the charge of the object, 7.25 μC (7.25 x \(10^-^6\) C)

- r is the distance from the charge to point B, which is half the length of the square's side, 0.201 m / 2 = 0.1005 m

Plugging in the values, we have:

E = (8.99 x \(10^9 N m^2/C^2\) * 7.25 x \(10^-^6\) C) / (0.1005 \(m)^2\)

E ≈ 1.622 x \(10^6\) N/C

Since the electric fields from the two charges at the lower corners have equal magnitudes and point in the same direction (upward), the total electric field at point B is twice the magnitude of the individual electric field:

Electric field at point B = 2 * E ≈ 2 * 1.622 x \(10^6\) N/C

Electric field at point B ≈ 3.244 x \(10^6\) N/C

Therefore, the electric field at point B, midway between the upper left and right corners of the square, is approximately 3.244 x \(10^6\)N/C upward.

Explanation:

There are several moral theories that could be applicable to this situation, but two that stand out are consequentialism and deontology.

Consequentialism is a moral theory that focuses on the consequences of actions. According to consequentialism, an action is morally right if it leads to the best overall outcome or consequences. In this case, Youngster-A seems to be considering the potential consequences of going to the party, particularly in terms of how it could affect their lives days or weeks later. Youngster-B, on the other hand, seems to be more focused on the immediate pleasure and excitement of attending the party. From a consequentialist perspective, it would be important to consider all of the potential consequences of attending the party before making a decision.

Deontology is a moral theory that emphasizes the duty or obligation to follow certain moral rules or principles. According to deontology, some actions are inherently right or wrong, regardless of their consequences. In this case, there are several moral rules and principles that could be relevant, such as the duty to obey the law, the obligation to avoid harm to oneself or others, and the responsibility to act in a way that aligns with one's values and beliefs. From a deontological perspective, it would be important to consider how attending the party aligns with these moral rules and principles.

Both consequentialism and deontology offer different ways of approaching moral decision-making in this situation. Ultimately, the decision of whether or not to attend the party will depend on the individual's values, beliefs, and priorities, as well as the specific circumstances of the party and potential consequences.

Mark's work decreases when he climbs the same flight of stairs again in the same amount of time without the cello.

The correct answer is option D.

The amount of work Mark does depends on the weight of the cello, as well as the distance he climbs and the time it takes. Work is calculated using the formula :

Work = Force × Distance.
In the given scenario, Mark is carrying a full-sized cello while climbing the stairs. The weight of the cello adds to the force he exerts. So, the total force Mark exerts is the weight of the cello plus his own weight (375 N).

When Mark climbs the stairs with the cello, he is doing work against the force of gravity.

The work done is equal to the force exerted multiplied by the distance climbed (375 N + weight of cello) × 4 m.

Now, if Mark were to climb the same flight of stairs again in the same amount of time (3 seconds), but this time without the cello, the amount of work he does would decrease. This is because without the cello, the force exerted would only be Mark's weight (375 N), which is less than the total force exerted with the cello.

Therefore, mark's work decreases.

Answer:

- 0.33 m/s

Explanation:

An illustration is shown above,

In this case, since the two objects move in opposite directions before collision, then move together, the formula to be used is,

m1u1 - m2u2 = (m1 + m2)v

Where,

m1 = mass of the first object

u1 = initial velocity of the first object

v1 = final velocity of the first object

m2 = mass of the second object

u2 = initial velocity of the second object

v2 = final velocity of the second object

Therefore,

(4.0 • 3.0) - (8.0 • 2.0) = (4.0 + 8.0)v

12 - 16 = 12v

-4 = 12v

Divide both sides by 12,

44.4  is the work done by friction  14.4  s the velocity of the block at point C . Correct Option a)

Friction is the force that prevents solid surfaces, fluid layers, and material components from moving against each other. There are various kinds of friction.

Dry friction is the force that resists the relative lateral motion of two in touch solid surfaces. Dry friction is further classified as static friction ("stiction") between non-moving surfaces and kinetic friction ("stiction") between moving surfaces. Dry friction, with the exception of atomic or molecular friction, is caused by the interplay of surface characteristics known as asperities .

Answer:

a)  t₀ = 0.704 10⁻¹² s,  b)   #cycle = 2.05 10¹⁶ cycles ,  

c)    #_cycles = 7,418 10³² cycles,  d)   Δt = 4.6 10⁴ s

Explanation:

For this exercise we must use the relationship between the period and the frequency

       f = 1 / T

       T = 1 / f

let's apply this equation to our case

a) The time of a cycle is

       t = 1 / 1.420405 10¹²

       t₀ = 0.704 10⁻¹² s

b) number of cycles in 4 h

       t = 4 h (3600 s / 1h) = 14400 s

Let's use a direct rule of proportions (rule of three). If there is 1 cycle in t₀, how much cycle is there

      #_cycles = t (1 / t₀)

      #_cycle = 14400 s (1 cycle / 0.704 10⁻¹² s)

      #_cycle = 2.0454 10¹⁶ cycles

      #cycle = 2.05 10¹⁶ cycles

c) cycles since the age of the Earth

     t = 4.6 10⁹ years (365 days / year) (24 h / 1 day) (3600 s / 1 h)

     t = 5.2224 10²⁰ s

    #_cycles = t (1 / to)

    # _cycles = 5.2224 10²⁰ (1 / 0.704 10⁻¹²)

    #_cycles = 7,418 10³² cycles

d) Let's use the direct proportion rule. If you have a lag of Δt₁ = 1s at t₁ = 1 10⁵ years, what is the lag (Δt) at t = 4.6 10⁹ years

        Δt = t (Δt₁ / t₁)

        Δt = 4.6 10⁹ years (1 s / 10⁵ years)

        Δt = 4.6 10⁴ s

The cannon's forward post-explosion velocity is 6.18 m/s.

Momentum is the force necessary to bring an item to a complete halt in a unit of time and is determined by multiplying an object's mass by its velocity. The overall momentum is equal to the sum of the individual momenta for any array of multiple objects.

Total momentum before = Total momentum after

(3.5 kg + 0.52 kg) × 1.27 m/s = 3.5 kg × v_cannon + 0.52 kg × 75 m/s

where v_cannon is the velocity of the cannon after the explosion.

Simplifying and solving for v_cannon, we get:

v_cannon = (0.52 kg × 75 m/s - (3.5 kg + 0.52 kg) × 1.27 m/s) / 3.5 kg

v_cannon = 6.18 m/s.

The correct answer is B. Weight directly measures force while mass directly measures the amount of matter.

Explanation:

Weight and mass are two related but not identical concepts. The first term "mass" can be found by measuring the amount of matter in a body or substance. For example, the mass in an apple is around 80 grams depending on its size. In this context, mass is measured using units such as grams or kilograms. On the other hand, weight considers not only the matter in an object but the force exerted in it, especially, the gravitational force. In the case of the apple, the weight is 1 N as newtons (N) are used to measure force and this is the result of multiplying the mass by gravity. According to this, option B is correct.
