Explanation:

Answer: The period will be larger, with T = 4.92 seconds

Explanation:

The period of a pendulum can be obtained by the equation

T = 2*pi*√(L/g)

Where pi = 3.14, L = lenght of the pendulum and g = gravity acceleration.

You can see that the gravitational acceleration is on the denominator, this means that if we decrease the value of g, then the value of T will increase.

In Earth we have that:

2s = 2*3.14*√(L/9.8m/s^2)

L = (1/3.14)^2*9.8 m = 1m

In the moon we have g = 1.62 m/s^2

then the period in the moon is:

T = 2*3.14√(1/1.62) = 4.92s

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:

The answer is the atom with 3 protons, 4 neutrons, and 3 electrons.

Explanation:

The reason why, is because protons are positive, neutrons are neutral, and electrons are negative. The protons cancel out the electrons, and the neutrons are just there.

Answer:

|v2| = 3.27

Explanation:

You have two vector v1 and v2. The relation between the magnitudes of both vectors is given by:

[tex]\frac{|v_1|}{|v_2|}=\frac{5}{2}[/tex]

Furthermore, the projection (the dot product) of one vector on the other one is given by the following formula:

[tex]v_1 \cdot v_2 = |v_1||v_2|cos\theta[/tex]

The dot product between v1 and v2 is 3√29. If you multiply the right hand side of the last equation by |v2|/|v2| you obtain:

[tex]3\sqrt{29}=\frac{|v_1|}{|v_2|}|v_2|^2cos(53\°)[/tex]

you do |v2| the subject of the formula:

[tex]|v_2|=\sqrt{\frac{|v_2|}{|v_1|}\frac{3\sqrt{29}}{cos53\°}}\\\\|v_2|=\sqrt{\frac{2}{5}\frac{3\sqrt{29}}{cos53\°}}=3.27[/tex]

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.

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

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]

Explanation:

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
