While operating around buildings, the remote pilot in command (PIC) should be aware of the creation of wind gusts that change rapidly in direction and speed, creating turbulence.

The ATC authorization that is also known as air traffic control authorisation is the mechanism by which an operator is accepted to be able to operate in a controlled airspace. Usually the authorized pilot are aware of the wind gusts that change rapidly in direction and speed, creating turbulence.

Any pilot who is operating within a airspace of high buildings that is a controlled airspace is required to have the ATC authorization weather if the aircraft that he is using is small in size or big.

Usually the air space surface that is present above 10000 feet of the surrounding of the nation is considered to be the class B Airspace where fast wind are are observed.

Answer:

A) The free body diagrams for both the load of bricks and the counterweight are attached.

B) a = 2.96 m/s²

Explanation:

A)

The free body diagrams for both the load of bricks and the counterweight are attached.

B)

The acceleration of upward acceleration of the load of bricks is given by the following formula:

a = g(m₁ - m₂)/(m₁ + m₂)

where,

a = upward acceleration of load of bricks = ?

g = 9.8 m/s²

m₁ = heavier mass = mass of counterweight = 28 kg

m₂ = lighter mass = mass of load of bricks = 15 kg

Therefore, using these values in equation, we get:

a = (9.8 m/s²)(28 kg - 15 kg)/(28 kg + 15 kg)

a = 2.96 m/s²

Answer:

2.96 m/s2

Explanation:

Set Up: Apply ∑→ Fy=m → ay to the load of bricks & to the counterweight.  

The tension is the same at each end of the rope.  

The rope pulls up with the same force T on the bricks & on the counterweight.    

The counterweight accelerates downward and the bricks accelerate upward; these accelerations have the same magnitude.  

Solve: Apply ∑→ Fy=m → ay to each object. The acceleration magnitude is the same for the two objects.  

For the bricks take +y to be upward since vector a (→ a) for the bricks is upward: ∑→ Fy=m → ay  

T – m1g = m1a  

For the counterweight take +y to be downward since → a is downward: ∑→ Fy=m → ay ,  m2g – T = m2a  

Add the two equations to eliminate T and then solve for a.  

m2g ⎯ m1g = m1a + m2a  

(m2⎯ m1)g = (m1 + m2)a  

a = (m2− m1/ m1 + m2)g    

  = (28 kg−15 kg/15 kg+28 kg) (9.8 m/s2) = 2.96 m/s2

Answer:

Explanation:

Distance of barrier = 40 m

Distance covered during reaction time = .75 x 40 = 30 m .

distance covered during deceleration can be calculated as follows .

v² = u² - 2 a s

0 = 40² - 2 x 10 x s

s = 80 m

Total distance covered before coming to rest = 30 + 80 = 110 m

Distance of barrier = 40 m , so it will hit the barrier .

1) The velocity of the pin after the collision is 107.4 m/s.

2) The velocity of the two cars as the collision is inelastic is 48.2 m/s.

We know that by the principle of the conservation of linear momentum, the momentum before Collison is equal to the total momentum after collision. Now we have to use this principle in the both questions that we have here.

1) Given that;

Total momentum before collision = Total momentum after collision

(41.7 * 59.1) + (4.17 * 0) = (41.7 * 48.35) + ( 4.17 * v)

We then have;

2464 + 0 = 2016 +  4.17v

2464 - 2016 = 4.17v

v = 2464 - 2016 /4.17

v = 107.4 m/s

2) Given that;

Total momentum before collision = Total momentum after collision

(51.3 * 50.1) + (100 * 47.2) = (100 +  51.3)v

2570 + 4720 = 151.3v

v = 2570 + 4720/151.3

v = 48.2 m/s

Answer:

29 m/s

Explanation:

Assuming the bridge and the platform are back to back,

Average speed = Total Distance/ Total Time

Avg S = 1,450m/50s = 29 m/s

The average speed of the train is 29 m/s

The average speed is defined as the ratio of total distance traveled and the total time taken.

    Total distance = 650 m + 800 m = 1450 m

     Total Time      = 20 s + 30 s = 50 s

    Average speed = total distance/total time

                               = 1450 / 50

                               = 29 m/s is the average speed of the train.

The coefficient of thermal conductivity (k) is related to the rate of heat flow (Q), the cross-sectional area (A), the length (L), the temperature difference (ΔT), and the thermal resistance (Rth) by the following equation:

k = Q / (A * ΔT * L) = Rth * (A * ΔT)

Reorganizing this equation gives:

Rth = k / (A * ΔT)

The given information in the problem is:

Rate of heat flow (Q) = 14.0 watts

Thermal resistance (Rth) = (350 mm × 350 mm × 15 mm) / (14.0 watts) = 31.5 mm⁴/C

Temperature difference (ΔT) = 28°C

Substituting these values into the equation, we have:

k = Q / (A * ΔT) = 14.0 W / (0.35 m² * 28°C) = 1.94 W/mK

So the coefficient of thermal conductivity (k) for this wood is approximately 1.94 W/mK.

the girl's velocity after they push off is 0.816 m/s.

Velocity is described as the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time.

The momentum of the boy after he pushes off is given by m_boy * v_boy = -747 N * 0.540 m/s = -405.08 N * m/s.

The momentum of the girl after she pushes off is denoted as   m_girl * v_girl, where m_girl is the mass of the girl and v_girl is her velocity.

The principle of conservation of momentum requires that the total momentum of the two-person system before and after the push off must be the same, hence we have:

m_boy * v_boy + m_girl * v_girl = 0

Substituting in the values for m_boy and v_boy, we find:

-405.08 N * m/s + m_girl * v_girl = 0

Solving for v_girl, we find:

v_girl = 405.08 N * m/s / m_girl = 405.08 N * m/s / 497 N = 0.816 m/s.

The earthquake would occur 13 minutes before 10:05 a.m. which will be at 9.52 am.

The p-waves travel with a constant velocity of 7 km/s

The time can be calculated by using the formula

t = d / v

where

T1 =  10:05 a.m

d is the distance they take to travel from the epicenter

v is the speed of the p-waves

On average, the speed of p-waves is

v = 7 km/s

d = 5600 km (given)

Substituting the values in the formula;

t = d / v

t = 5600 ÷ 7

t = 800 seconds

Converting into minutes,

t = 800 ÷ 60

t = 13.3

N/C = V/m.

Explanation:

The SI unit of electric field is N/C. Sometimes the units are written as V/m.

We know that,

1 V = 1 J/C

Using dimensional analysis,

The dimensional formula for Joules is [M¹L² T⁻²].

The dimensional form of coulomb is [M⁰ L⁰ T¹ I¹].

So,

J/C = [M¹L² T⁻³I¹] ...(1)

The dimensional formula of Newton is [M¹ L¹ T⁻²]

The dimensional form of coulomb is [M⁰ L⁰ T¹ I¹].

N/C= [M¹L² T⁻³I¹] ....(2)
