Answer:

Spirit of St. Louis

Explanation:

Charles Lindbergh was known as a prolific aviator during the early twentieth century. He is well known for the flight he took from Long Island, New York, to Paris, France. It was a continuous flight across the Atlantic Ocean.

The plane he used was the Spirit of St. Louis which took more than 33 hours to complete the journey. It was the first successful flight of this kind. The airplane flew from Long Island on May 20 and landed in Paris on May 21.

Two forces F1 and F2 are applied at the same point of an object. F1 has a magnitude of 20 N and is directed at an angle of 120 d

butalik [34]

Answer:

The value is $\vec F_{n} = -5.67 i +14.82 j \ \ N$

Explanation:

From the question we are told that

The magnitude of the first force is $F_1 = 20 \ N$

The angle which it makes with the x-axis is $\theta_1 = 120 ^o$

The magnitude of the second force is $F_2 = 5 \ N$

The angle which it make with x-axis is $\theta_2 = -30 ^o$

Generally the x-component of the first force is

$F__{1x}} = 20 cos (120 )$ '

=> $F__{1x}} = -10 \ N$

Generally the y-component of the first force is

$F__{1y}} = 20 sin (120 )$

=> $F__{1y}} = 17.32 \ N$

Generally the vector representation of the first force is mathematically represented as

$\vec F_1 = [ -10 i + 17.32 j \ ] \ N$

Generally the x-component of the second force is

$F__{2x}} = 20 cos (-30 )$

=> $F__{2x}} = 4.33 \ N$

Generally the y-component of the second force is

$F__{2y}} = 20 sin (-30 )$

=> $F__{2y}} = -2.5 \ N$

Generally the vector representation of the first force is mathematically represented as

$\vec F_2 = [ 4.33 i - 2.5 j \ ] \ N$

Generally the net force acting that point is mathematically represented as

$\vec F_{n} = -10 i + 17.32 j + 4.33 i - 2.5 j$

=> $\vec F_{n} = -5.67 i +14.82 j \ \ N$

Observer A, who is at rest in the laboratory, is studying a particle that is moving through the laboratory at a speed of v=0.8c

Studentka2010 [4]

Answer:

30.96 m

Explanation:

If the particle has a lifetime of 129 ns as measured by observer A, and has a speed of 0.8c as measured by observer A, the distance between the markers will be:

d = v * Δt

v = 0.8*c = 0.8 * 3e8 = 2.4e8

Δt = ζ = 129 ns = 1.29e-7 s

d = 2.4e8 * 1.29e-7 = 30.96 m

This is the distance as measured by observer A.

At what speed do a bicycle and its rider, with a combined mass of 100 kg, have the same momentum as a 1400 kg car traveling at 6

Ilia_Sergeevich [38]

Momentum of car

Given: Mass m= 1,400 Kg; V = 6.0 m/s

Formula: P = mv

P = (1,400 Kg)(6.0 m/s)

P = 8,400 Kg.m/s

Velocity of the rider to have the same momentum as a car.

Mass of rider and bicycle m = 100 Kg

P = mv

V = P/m

V = 8,400 Kg.m/s/100 Kg

V = 84 m/s
