Answer:

T1 = T2 = 602.33 N

Explanation:

I attached an image of the forces diagram below.

The x component of the forces for this cases is:

[tex]\Sigma F_x=T_1cos\theta-T_2cos\theta=0\\\\T_1cos\theta=T_2cos\theta\\\\T_1=T_2[/tex]

And the y components:

[tex]\Sigma F_y=T_1sin\theta+T_2sin\theta-W=0\\\\T_1=T_2=T\\\\\Sigma F_y=2Tsin\theta=W\\\\T=\frac{W}{2sin\theta}[/tex]

The angle is calculated by using the information about the length of the cable and the vertical distance of the traffic light:

[tex]\theta=tan^{-1}(\frac{1}{15})=3.81\°[/tex]

Thus, you obtain:

[tex]T=\frac{80N}{2(sin3.81\°)}=601.33N[/tex]

hence, the tension in both segments of the cable is 602.33 N

Answer:

B) Distance and Time

Explanation:

Equation for speed: S = D / T

Speed equals the distance you traveled divided by the amount of time it took to get to that destination.

The two factors which are required to determine the speed of a object are distance traveled by it and time taken by it.

The speed is the rate at which the total distance by a object is traveled in the time taken.

Speed of a object can be given as,

[tex]s=\dfrac{d}{t}[/tex]

Here, (d) is the distance traveled by the object and (t) is time taken but the object to cover that distance.

As the unit of the distance is measured in the meter and the time measure in the second. Thus the speed of a object is measured in the meter per second.

In the vehicles the speed of vehicle is also measured in the kilometre per hour or miles per hour.

Hence, the two factors which are required to determine the speed of a object are distance traveled by it and time taken by it.

Thus the option B is the correct option.

Answer:

the stones are released from rest at the same time, the stone that is on Earth to have more acceleration must first reach the ground

Explanation:

For this exercise we will use the law of universal attraction on each planet and Newton's second law to calculate the body's acceleration on each planet

          F = ma

          F = G m M / r²

Where G is the universal gravitational constant, m the mass of the body, M the mass of the planet and r the distance

Let's start with the Earth

       G m M / r² = m a

        a = G M / r²

let's look for the distance

    r = [tex]R_{e}[/tex] + h

    a = G M / (R_{e} + h)² = (G M /R_{e}²)  1 /(1 + h /R_{e})² ²

as h << R_{e} we can expand this function

    (1 + h /R_{e})⁻² = 1 -2 h / Re + ...

with h /R_{e} it is very small we can despise it

        a = G M /R_{e}

the amount in parentheses is called the acceleration due to gravity

     g = G M / R_{e}²

     g = 6.67 10⁻¹¹ 5.98 10²⁴ / (6.37 10⁶)²

     g = 9.8 m / s ²

Now let's calculate the acceleration on Mars, let's use index 2 for this planet

     a = G M2 / R_{2}²

     a = 6.67 10⁻¹¹ 6.42 10²³ / (3.37 10⁶)

     a = 3.77 m / s²

Let's analyze these results as the stones are released from rest at the same time, the stone that is on Earth to have more acceleration must first reach the ground

 we can use the equation

           y = v₀ t - ½ to t2

           v₀ = 0

           t = √ (2y / a)

we see that as the acceleration is greater the time decreases

Answer:

0.45 miles

Explanation:

since, car will be running on the edge of track, distance covered in one lap by car will be equal to circumference of track.\

we will use value of pi as 22/7

Circumference for any circular shape is given by [tex]\piD[/tex][tex]\pi D[/tex]

Hence, in one lap [tex]\pi D[/tex] distance will be covered

in 7 laps [tex]7 \pi D[/tex] distance will be covered.

but is given that 7 laps should be equal to 10 miles

so 10 miles will be equal to [tex]7\pi D[/tex]

[tex]7\pi D= 10 \ miles\\=> 7*(22/7)* D= 10 \ miles\\=> 22D = 10 \ miles\\=> D = 10/22 \ miles\\=> D = 0.45 \ miles[/tex]

Thus, diameter of track will be 0.45 miles to meet the requirement.

Answer:  5 years

Explanation:

Expression for rate law for first order kinetics is given by:

[tex]t=\frac{2.303}{k}\log\frac{a}{a-x}[/tex]

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant  = x

a - x = amount left after decay process  = [tex]\frac{x}{16}[/tex]

a) for calculating k

[tex]20=\frac{2.303}{k}\log\frac{x}{\frac{x}{16}}[/tex]

[tex]k=\frac{2.303}{20}\log{16}[/tex]

[tex]t_{\frac{1}{2}}=\frac{0.693}{0.138years^{-1}}[/tex]

[tex]t_{\frac{1}{2}}=5years[/tex]

Thus its half life is 5 years

Answer:

1,211.1 kg.

Explanation:

the force of gravity is less on the moon than on earth, so if the man can lift 200kg on earth, he could lift a greater amount on the moon because there is less resistance from gravity.

To know the amount of mass he can lift on the moon, we first need to know the amount of weight that is equivalent to those 200kg here on earth. This because the weight of the object is equal to the force that must be applied to lift it, and that force is applied by the man and it will be the same here and on the moon.

We calculate weight using the formula:

[tex]w=mg[/tex]

where [tex]w[/tex] is the weight of the object (the force with which the earth attracts the object) [tex]m[/tex] is the mass and g the acceleration of gravity.

so

[tex]w=200g[/tex]

for earth the acceleration due to gravity is:  [tex]g=9.81m/s^2[/tex]

thus:

[tex]w=(200kg)(9.81m/s^2)\\w=1962N[/tex]

now we use this value to calculate the mass he can lift on the moon, since for the moon [tex]g=1.62m/s^2[/tex].

we use the same equation, w =mg substituting w = 1962N and [tex]g=1.62m/s^2[/tex]:

[tex]w=mg\\\\1962N=m(1.62m/s^2)\\\\m=\frac{1962N}{1.62m/s^2}\\\\ m=1,211.1kg[/tex]

he can lift 1,211.1 kg.

You can also find the result using the approximate value of the acceleration of gravity on the moon as g/6, where g is the acceleration on earth.

Answer:

Pmax = 67.5 KN

Explanation:

We need to calculate the maximum allowable value of P for both aluminum and steel bars.

FOR STEEL BARS:

Since,

(σallow)st = (Pmax)st/A

where,

(σallow)st = maximum allowable stress of steel bar = 200 MPa = 2 x 10⁸ Pa

A = Cross-sectional area of steel bar = 450 mm² = 0.45 x 10⁻³ m²

(Pmax)st = Maximum allowable force for steel bar = ?

Therefore,

2 x 10⁸ Pa = (Pmax)st/0.45 x 10⁻³ m²

(Pmax)st = (2 x 10⁸ Pa)(0.45 x 10⁻³ m²)

(Pmax)st = 9 x 10⁴ N = 90 KN

FOR Aluminum BARS:

Since,

(σallow)al = (Pmax)al/A

where,

(σallow)al = maximum allowable stress of Al bar = 150 MPa = 1.5 x 10⁸ Pa

A = Cross-sectional area of Aluminum bar = 450 mm² = 0.45 x 10⁻³ m²

(Pmax)al = Maximum allowable force for Aluminum bar = ?

Therefore,

1.5 x 10⁸ Pa = (Pmax)al/0.45 x 10⁻³ m²

(Pmax)al = (1.5 x 10⁸ Pa)(0.45 x 10⁻³ m²)

(Pmax)al = 6.75 x 10⁴ N = 67.5 KN

Since,

(Pmax)al < (Pmax)st

Therefore,

The maximum allowable force will be:

Pmax = (Pmax)al

Pmax = 67.5 KN

The question in english is:

A ray of light falls under an angle of incidence of 30 degrees on a flat surface that separates two transparent materials with indexes of refractions 1.60 and 1.40, respectively.

Calculate the angle of refraction (from the environment with the lower index of refraction)

Solution

According to Snell's Law :

[tex]n_{1}sin(\theta_{1})=n_{2}sin(\theta_{2})[/tex]

Where:

[tex]n_{1}=1.6[/tex]  is the first medium index of refraction

[tex]n_{2}=1.4[/tex]  is the second medium index of refraction

[tex]\theta_{1}=30\°[/tex]  is the angle of the incident ray

[tex]\theta_{2}[/tex] is the angle of the refracted ray

We need to find [tex]\theta_{2}[/tex] from the equation above,

[tex]\theta_{2}=sin^{-1}(\frac{n_{1}}{n_{2}}sin\theta_{1} )[/tex]

[tex]\theta_{2}=sin^{-1}(\frac{1.6}{1.4}sin(30\°)[/tex]

The frequency [tex]\mathbf{f = 0.36 \ Hz}[/tex]

Amplitude A = 25.5 cm

The maximum speed of the glider is [tex]\mathbf{v = 56.87 \ rad/s}[/tex]

Explanation:

Given that:

the time taken for 11 oscillations is 31 seconds ;

SO, the time taken for one oscillation is :

[tex]T = \frac{31}{11}[/tex]

T = 2.82 seconds.

The formula for calculating frequency can be expressed as :

[tex]f = \frac{1}{T}[/tex]

[tex]f = \frac{1}{2.82}[/tex]

[tex]\mathbf{f = 0.36 \ Hz}[/tex]

The amplitude is determined by using the formula:

[tex]A = \frac{d}{2}[/tex]

The limits that the spring makes the oscillations are from 10 cm to 61 cm.

The distance of the glider is, d = (61 - 10 )cm = 51 cm

Replacing 51 for d in the above equation

[tex]A = \frac{51}{2}[/tex]

A = 25.5 cm

The maximum speed of the glider is:

[tex]v = A \omega[/tex]

where ;

[tex]\omega = \frac{2 \pi}{T}[/tex]

[tex]\omega = \frac{2 \pi}{2.82}[/tex]

[tex]\omega = 2.23 \ rad/s[/tex]

[tex]v = A \omega[/tex]

[tex]v = 25.5 *2.23[/tex]

[tex]\mathbf{v = 56.87 \ rad/s}[/tex]

The magnetic flux through the loop when the plane of the loop is perpendicular to the magnetic field is 0.0256 Weber.

The magnetic field is the region of space where a charged object experiences magnetic force when it is moving.

The formula for magnetic flux is given as;

φ = BAcosθ

Given, a rectangular loop of wire that can rotate about an axis through its center is placed between the poles of a magnet in a magnetic field with a strength of 0.40 T. The length of the loop L is 0.16 m and its width w is 0.040 m.

Area of the loop = L x w

                        A  = 0.16 x 0.040 m

                         A = 0.0064 m²

So, flux will be

φ = 0.4 x  0.0064 x cos90°

φ = 0.00256 Wb

Thus, magnetic flux through the loop when the plane of the loop is perpendicular to the magnetic field is 0.0256 Weber.
