Answer:

a seat

Explanation:

The phrase “seat value” is used in the hospitality and bar sectors to describe how much money each seat or square foot of customer area must generate to justify its existence.

An area to sit is a seat. The phrase may also refer to headquarters in a more general meaning as well as extra elements such a back, armrest, and head restraint.

Being in the centre allows you to benefit from both the advantages of both front and back seating while balancing out their extremes. While you're still close enough to be paying careful attention to the lecture, the middle rows will relieve you of the pressure and expectations of the front.

By remaining seated, students help avoid physical altercations. There is more time spent on task when pupils are seated.

Environmental psychology, which gives people the impression that they have some degree of influence over their daily lives, is the driving force behind all of this behavior.

Therefore, seat used by people.

Answer:

In an year about 6 major hurricanes and 3 minor storms occurs.

Explanation:

Amir has traveled 245.072 meters up the slope when they pass.

For Amir:

v = u + at

s = ut + 1/2 at^2

where

u = 22.0 km/h = 6.11 m/s (initial velocity)

a = -0.250 m/s^2 (deceleration)

v = 0 m/s (final velocity when Amir and Becky pass)

s = 250 m (distance Amir travels up the slope)

For Becky:

v^2 = u^2 + 2as

where

u = 8.0 km/h = 2.22 m/s (initial velocity)

a = 0.50 m/s^2 (acceleration)

v = 0 m/s (final velocity when Amir and Becky pass)

s = distance Becky travels down from the top

At the instant they pass, both Amir and Becky will have traveled the same distance, so we can equate their respective distances traveled:

250 m + x = s

We can solve for s by first finding the distance Becky travels,

0^2 = (2.22 m/s)^2 + 2(0.50 m/s^2)s

s = (2.22 m/s)^2/(2 x 0.50 m/s^2) = 4.928 m

Now,

250 m + x = 4.928 m

x = -245.072 m

The light from the green glow stick held by the Olympic sprinter will appear redshifted.

The phenomenon of redshift occurs when the source of light is moving away from the observer. In this case, as the sprinter is running towards you, the distance between you and the glow stick is decreasing over time. This decrease in distance causes a Doppler shift in the frequency of the light emitted by the glow stick.

Since the light is redshifted, its wavelength increases and the frequency decreases compared to its original emitted frequency. As a result, the light that reaches your eyes appears more towards the red end of the visible spectrum.

It is important to note that the color of the glow stick itself remains the same, but due to the relative motion between the source (the sprinter) and the observer (you), the light undergoes a change in frequency and appears redshifted.

This phenomenon is similar to the redshift observed in cosmology, where the light from distant galaxies appears to be redshifted due to the expansion of the universe.

If energy is conserved, then initial (PE + KE) = final (PE + KE). So, the correct option is A.

The law of conservation of energy states that, energy can neither be created nor be destroyed, but can be transformed from one form to another.

Here,

According to law of conservation of energy,

The total energy of an isolated system remains constant. That means, the total energy of the system in the initial state will be same as that in the final state.

The total mechanical energy is the sum of kinetic energy and potential energy.

Explanation:

Answer:

The fundamental frequency of the stretched string is:

\(f=\) \(\frac{1}{2} \sqrt{\frac{T}{L} }\) [ T = Tension and μ = mass per unit length]

Here,

 μ = \(\frac{m}{L} = \frac{Vp}{L} = Ap\)

\(f= \frac{1}{2} \sqrt{\frac{T}{Ap} }\)

If T is halved and A is doubled,

\(f= \frac{1}{2} \sqrt{\frac{T'}{A'p} } = \sqrt{\frac{1}{2* 2* A* p} } = \frac{1}{2} (\frac{1}{2} \sqrt{\frac{T}{Ap} } = \frac{1}{2} f\)

Thus, the frequency is reduced to half if its tension is halved and the area of cross-section of the string is doubled.

When the tension is halved and the area of cross section is doubled, the frequency increases by a factor of 1.414.

The frequency of transverse vibration of a stretched string is calculated as follows;

\(f = \frac{1}{2l} \sqrt{\frac{T}{\mu} }\)

where;

\(f = \frac{1}{2l} \sqrt{\frac{T}{\mu} }\\\\f = \frac{1}{2l} \sqrt{\frac{Tl}{m} } \\\\f = \frac{l^2}{2l} \sqrt{\frac{T}{m} } \\\\f = \frac{A}{2l} \sqrt{\frac{T}{m}}\)

when the tension is halved and the area of cross section is doubled, the frequency is calculated as;

\(\frac{f_1}{A_1 \sqrt{T_1} } = \frac{f_2}{A_2\sqrt{T_2} } \\\\f_2 = \frac{f_1 A_2\sqrt{T_2}}{A_1 \sqrt{T_1} }\\\\f_2 = \frac{f_1 \times 2A_1\sqrt{0.5T_1} }{\sqrt{T_1} }\\\\f_2 = \frac{f_1 \times 2A_1 \times 0.7071\sqrt{T_1} }{\sqrt{T_1} }\\\\f_2 = 1.414 f_1\)

The state of tension created by biological needs is called drive.

Drive is a basic need that is pressing for fulfilment in psychology. It is typically caused by physiological tension, deficiencies, or imbalances (such as hunger and thirst) and drives an organism to take action. While some academics have used the terms "need" and "drive" interchangeably, others distinguish between need and drive as the psychological symptoms of deprivation (e.g., tension and restless or goal-directed activity).

Additionally, psychologists make a distinction between intrinsic impulses that are directly connected to fundamental physiological demands (such food, air, and water) and learned drives (e.g., addiction). Achievement, activity, affection, connection, curiosity, elimination, exploration, manipulation, motherhood, pain avoidance and sleep are a few more suggested drives or demands.

The angular momentum given to the engine is: L = I × ωL = 1 kg·m² × 69.8 rad/sL = 69.8 kg·m²/s

Torque (τ) = F × r

Maximum torque is produced when force is applied perpendicular to the radius, i.e. at 90°.So, sin 90° = 1

τ = F × r × 1

= F × r

The formula for the angular momentum is: Angular momentum (L) = I × ω

Where,I is the moment of inertiaω is the angular velocity. We know that,

τ = Iα .............(1)

From rotational equations,α = τ / I ..............(2)

The formula for the angular velocity is:ω = ωo + αt...............(3)

Substituting equation (2) in equation (1), we get,

τ = I(τ / I)

τ = τ

Therefore,τ = τ. So,α = τ / I. Substituting values of τ and r in equation (1), we get,

F × r = Iα

F × r = I(τ / I)

F × r = τ

I = (F × r) / τ

Substituting values of F, r and τ, we get  ,I = (250 N × 0.300 m) / (250 N × 0.300 m)I = 1 kg·m²

The angular velocity is:ω = ωo + αt.

As the car is started from rest, ωo = 0. So, ω = αt. Substituting values of α and t, we get,

ω = (τ / I) × t

ω = (250 N × 0.300 m) / (1 kg·m² × 0.19 s)

ω = 69.8 rad/s.

Answer: 1.70 m/s

Explanation:

suvat

s = 0.34m

u = 2.41 m/s

v = ?

a = -4.3 m/s2

t = ?

v^2 = u^2 + 2as

v^2 = 2.41^2 + 2*(-4.3)*0.34

v^2 = 2.8841

v = 1.698 m/s = 1.70 m/s

The velocity after two minutes is v = 616.67 m/s

Using the equation final velocity = beginning velocity + acceleration * time, the final velocity of this bus after two minutes is determined. Symbolically, v is represented as follows: vi = 60 km/h, a = 5 m/s2, and t = 2 minutes. First, we must translate 60 km/h into m/s. 50/3 m/s is equal to 60 km/h or 60,000 m/36 seconds.

When determining the final velocity, v

v = vi + a * t

120 seconds at v = 50/3 m/s + 5 m/s2

v = 50/3 m/s + 600 m/s

v = 16.67 m/s + 600 m/s

v = 616.67 m/s

After two minutes, the bus's speed is 616.67 m/s. For a bus, it is a pretty implausible velocity. The speed of this object is 2,220 km/h, exceeding the speeds of both air and jet aircraft. Your acceleration time should have been capped at 20 seconds or less.

Explanation:

The conversion of Fahrenheit to Celsius is the following:

\(T_{1} = \frac{5}{9}(^{\circ} F - 32) = \frac{5}{9}(- 4 - 32) = -20 ^{\circ} C\)

\(T_{2} = \frac{5}{9}(^{\circ} F - 32) = \frac{5}{9}(45 - 32) = 7.22 ^{\circ} C\)

Hence, the change on the Celsius scale is:

\( \Delta T = T_{2} - T_{1} = 7.22 - (-20) = 27.22 ^{\circ} C \)

Therefore, the change on the Celsius scale is 27.22 °C.
