Answer:

The resultant velocity is 86.1 mi/h.    

Explanation:

The law of cosines is given by:

\( c^{2} = a^{2} + b^{2} - 2abcos(\theta) \)

Where:

c: is the resultant velocity =?

a: is the velocity of the plane = 75.0 mi/h

b: is the velocity of the wind = 15.0 mi/h  

θ: is the angle between "a" and "b"                          

The angle between "a" and "b" can be found as follows:

\( \theta = 180.0 - 46.0 = 134.0 ^{\circ} \)

Now, by using the law of cosines we have:

\( c^{2} = (75.0)^{2} + (15.0)^{2} - 2*75.0*15.0*cos(134.0) = 7413.0 \)

\( c = 86.1 mi/h \)    

Therefore, the resultant velocity is 86.1 mi/h.    

The law of sines is:

\( \frac{a}{sin(\gamma)} = \frac{b}{sin(\alpha)} = \frac{c}{sin(\theta)} \)

Where:

γ: is the angle between "b" and "c"

α: is the angle between "a" and "c"

So, if we want to find "c" by using the law of sines, we need to know another angle besides θ (γ or α), and the statement does not give us.

Approximately 47.37% of the soil volume is pore space, and approximately 52.63% is solid particles.

To calculate the percentage of pore space and solid particles in the soil volume, we can use the following formula:

Pore space percentage = ((Particle density - Bulk density) / Particle density) x 100

Solid particles percentage = 100 - Pore space percentage

Given:

Bulk density = 1.4 Mg/m³

Particle density = 2.66 Mg/m³

Substituting the values into the formulas:

Pore space percentage = ((2.66 - 1.4) / 2.66) x 100

Solid particles percentage = 100 - Pore space percentage

Calculating the values:

Pore space percentage ≈ 47.37%

Solid particles percentage ≈ 52.63%

Therefore, approximately 47.37% of the soil volume is pore space, and approximately 52.63% is solid particles.

Answer:

1) F = 24 N

2) Distance = 1 m

Explanation:

We are given;

Mass; m = 120 g = 0.12 kg

Initial velocity; u = 20 m/s

Final velocity; v = 0 m/s since it came to rest.

Time; t = 0.1 s

We can calculate acceleration from Newton's first equation of motion;

a = (v - u)/t

a = (0 - 20)/0.1

a = -200 m/s²

1) magnitude of the resistance will be;

F = ma

F = 0.12 × (-200)

F = -24 N

Since, we are dealing with the magnitude, we will take the absolute value. Thus, F = 24 N

2) To find the distance moved by the bullet, we know that;

Distance = Average speed × time

Thus;

Distance = ((v + u)/2) × t

Distance = ((0 + 20)/2) × 0.1

Distance = 1 m

Answer:

in a plane flying above Earth

Explanation:

Gravity is the force that draws  objects toward center of the earth. If you throw an object up on the earth's surface, you will notice that it will fall back to the ground due to the earth's gravitational pull on the object.

However, the further one goes from the earth's surface, the lesser the gravitational pull. Therefore the cat will experience less gravitational pull in an airplane flying at a higher altitude.

To protect wiring before it gets to the fuse box, a circuit breaker is installed.

A circuit breaker is a device that automatically switches off a circuit's flow of electricity when it detects a fault. This action helps to prevent fires, equipment damage, and electrical hazards. It is a device that functions as a safety guard for electrical circuits to keep the devices from becoming overloaded or shorted.

Circuit breakers safeguard the electrical equipment by breaking the flow of current when the current exceeds the permitted level, or when the current exceeds the rated level of a wire in a circuit. The fuses are a different type of protection that is installed between the device being protected and the circuit's power source.

Fuses are designed to stop the flow of electrical power when the current exceeds the fuse's safe capacity. In most cases, a fuse will blow before the electrical current reaches the device being protected, protecting it from damage.

a. Jessica's has a greater linear speed.

b. The centripetal acceleration of Julie and her horse is 0.148 m/s².

Jessica's has a greater linear speed.

To answer the question, we need to know what Linear speed is.

This is the tangential speed at which an object in circular motion moves. It is given by v = rω where

Now, given that Jessica is riding on a merry-go-round on an outer horse that sits at a distance of 8.0 m from the center of the ride and Jessica's sister, Julie, is on an inner horse located 6.0 m from the ride's center. Also, the merry-go-round is moving at constant angular speed.

Since Linear speed v = rω and ω = constant,

So, v ∝ r.

So, the girl with the greater distance from the center of the merry-go-round would have the greater linear speed.

Since

Since

So, Jessica's has a greater linear speed.

The centripetal acceleration of Julie and her horse is 0.148 m/s².

Centripetal acceleration a = rω² where

Since the merry-go-round turns once every 40.0 s, we have that ω = 2π/40.0 s

= π/20.0 s

= 0.157 rad/s

Since a = rω²

Substituting the values of the variables into the equation, we have

a = rω²

a = 6.0 m × (0.157 rad/s)²

a = 6.0 m × 0.0247 rad²/s²

a = 0.148 m/s²

So, the centripetal acceleration of Julie and her horse is 0.148 m/s².

\(\huge\boxed{\sf S = 18.75 \ meters}\)

Explanation:

Given Data:

Initial Velocity = Vi = 0 m/s (rest)

Final Velocity for 6 seconds = Vf = 25 m/s

Time (1) = T1 = 6 seconds

Time (2) = T2 = 3 seconds

Required:

Distance for 3 seconds = S = ?

Solution:

For 6 seconds, the acceleration will be:

\(\displaystyle a = \frac{Vf-Vi}{t} \\\\a = \frac{25 - 0}{6} \\\\a = 25 / 6\\\\\boxed{a = 4.167 \ m/s^2}\)

Since, acceleration is constant, it will be the same at 3 seconds as well.

Using second equation of motion to find Distance (S) with time being 3 seconds:

\(\displaystyle S= Vit+\frac{1}{2} at^2\\\\S = (0)(3)+ \frac{1}{2} (4.167)(3)^2\\\\S = \frac{1}{2} (4.167)(9)\\\\S = \frac{37.5}{2} \\\\\boxed{S = 18.75 \ meters}\\\\\rule[225]{225}{2}\)

Electric field strength at (2.6m,1.7m) is 25.9 V/m

Therefore, the term E can be used to determine the electric field intensity at a place whose coordinates are (x,y) (x,y)

V=250 (V⋅m) /√(x²+y²),  

E = ∂V/∂x i + ∂V/∂y j

If I is a vector along the x axis, and j is a vector along the y axis, both of which are unit vectors because their magnitudes are one.

∂V/∂x = -250x

           (x²+y²)³²

         = (-250*2.6)/29.97

=>   -21.68

∂V/∂x = -250y

           (x²+y²)³²

         = (-250*1.7)/29.97

=>   -14.18

so E(2.1,3) = -21.68 i  -14.18 j

E=√(∂V/∂x i² + ∂V/∂y j²)

E= √(-21.68² + -14.18²)

E=√ (470+201)= 25.9

therefore, the electric field's strength at (2.6m,1.7m) =25.9 V/m

My arms are doing a negative work

Explanation:

When you set something on the ground, the displacement of the object set towards the ground is in the downward direction. which means that, in this case, there is a downward displacement.

As the object is set on the ground, the force exerted by the arms on the object acts in the upward direction.

Summarily, direction of force is upwards while the direction of displacement is downwards.

Since the force and displacement act in opposite direction, a negative work is said to be done.
