Answer:

220km

Explanation:

Given parameters:

Distance traveled from Minnehaha to Nut Plains  = 11km

Distance traveled to Dover  = 209km

Unknown:

The distance the soft drink distributor traveled  = ?

Solution:

To solve this problem, we  must understand that distance is the total length of path covered in a journey.

 So;

     Distance  = 209km + 11km  = 220km

The soft drink distributor covered 220km

Answer:

Explanation:

Answer:

v = 88.89 [m/s]

Explanation:

To solve this problem we must use the principle of conservation of momentum which tells us that the initial momentum of a body plus the momentum added to that body will be equal to the final momentum of the body.

We must make up the following equation:

[tex]F*t = m*v[/tex]

where:

F = force applied = 4000 [N]

t = time = 0.001 [s]

m = mass = 0.045 [kg]

v = velocity [m/s]

[tex]4000*0.001=0.045*v\\v=88.89[m/s][/tex]

Answer:

   F = 93.25 lb

Explanation:

To solve this problem let's use the rotational equilibrium condition

         Σ τ = 0

let's fix a reference system located at the end of the table, the position of Juan and assume the counterclockwise turns as positive

        F_jhon 0 - w l / 2 - W (l-4.9) + F l = 0

        F = w l / 2 + W (l -4.9) / l

where w is the weight of the table and W the weight of the box

let's calculate

        F = (44.5 12/2 + 120 (12- 4.9)) / 12

        F = 93.25 lb

The term potential energy is the energy possessed by a body by virtue of its position. It is different from kinetic energy which is due to the state of motion of a body.

Wave velocity = Wavelength × Frequency

Thus, we can say that wavelength is inversely proportional to the frequency.

FALSE - Only electromagnetic waves can travel through a vacuum; mechanical waves such as sound waves require a particle-interaction to transport their energy. There are no particles in a vacuum.

Answer:

The air will stop pouring out of the hole in the tire when the pressure inside the tire is equal to atmospheric pressure

Explanation:

The question relates to equilibrium conditions

The given parameters are;

The condition of the pressure of the air in the tire, P = Pressurized, P > Atmospheric pressure

The pressurized air is let out of the tire through a hole made by a nail

Therefore;

When the pressure inside the tire is more than atmospheric pressure, the force per unit area of the air from the side of the hole inside the tire is more than the force per unit area acting in the opposite direction and the pressure forces the air out of the tire

Therefore, the air continues pouring out of the hole in the tire up to the point when the pressure inside the tire becomes equal to atmospheric pressure, at which point the force per unit area of the air on either side of the hole are equal.

Answer:

r = 1.3m

Explanation:

The moment of inertia of a solid sphere can be expressed using the formula;

I = ⅖ mr²

Where;

I = moment (kgm²)

m = mass of the sphere (kg)

r = rotational radius of the sphere (m)

Based on the provided information in this question, I = 1.52 kgm², m = 2.25 kg, r = ?

1.52 = ⅖ × 2.25 × r²

1.52 = 0.4 × 2.25 × r²

1.52 = 0.9 × r²

1.52 = 0.9r²

r² = 1.52/0.9

r² = 1.688

r² = 1.69

r = √1.69

r = 1.3m

This question asks us to identify where Freida's appendicular injury. It cannot involve a body part in the axial region, so the head, neck, chest, and abdomen are not correct. Therefore, we can eliminate choices B (chest and head), C (abdomen), and D (neck), leaving A as the correct answer.

Answer:

D. Increasing resistance and keeping current from A P E X :))

Explanation:

The decreasing resistance and keeping current constant leads decreasing in voltage option (C) is correct.

Voltage is the force applied by the power source to charged electrons in a conducting loop, allowing them to perform tasks such as igniting light.

As we know according to the ohm's law:

V = IR

Where 'V' is the volatge,

'I' is the current.

'R' is the resistance.

If we assume 'I' is constant

Then V∝R

As the resistance increases the voltage increases and vice versa.

Thus, the decreasing resistance and keeping current constant leads decreasing in voltage option (C) is correct.

Answer:

Yes cause he walks 6.7 miles

The displacement vector of the man is equal to 17.41 miles in the Northeast direction.

The displacement of an object can be defined as the shortest distance between two points. The displacement can be described as a vector quantity because contains both direction and magnitude. The displacement can be positive (+ve), negative, or zero and can change with time.

The distance is the total path traveled and is a scalar quantity as it has only magnitude, and no direction. The distance is always positive (+ve), it can never be equal to zero.

Given, a man moves 2.6 miles along AB in the East and then 6.7 miles North along BC.

The displacement (AC) of the man can be calculated by using Pythagoras' theorem:

AC² = AB² + BC²

AC² = (2.6)² + (6.7)²

AC² = 6.76 +44.89

AC = 17.41 miles

Therefore, the displacement vector of the man is 17.41 miles.

Answer:

The current is 1 A

Explanation:

Current in a Series Connection

When two or more elements are connected in series, all of them have the same current, and the sum of their individual voltages is the total voltage applied to the circuit.

According to Ohm's law:

V=R.I

Where V is the voltage, R is the resistance and I is the current of a circuit.

We have a voltage of V=1.5 V + 1.5 V = 3 V and a resistance of R=3 ohms.

We can calculate the current by solving for I:

[tex]\displaystyle I=\frac{V}{R}=\frac{3}{3}=1\ A[/tex]

Explanation:

For maximum benefit, the heart rates during exercise regimes should be between 60 to 80% of an individual's maximum heart rate.

The maximum heart rate varies from individuals to individuals and largely depends on age. It is calculated by subtracting one's age from 220. For example, a person that is 40 years old would have a maximum heart rate of;

  220 - 40 = 180 beats per minute.

Such a person's heart rates during exercises should be between 108 and 144 beats per minute for maximum benefits.
