Answer:

3.18 Nm

Explanation:

Given that:

Radius (r) = 15cm = 15/100 = 0.15m

θ = 45°

Applied force (F) = 30 N

The Torque can be obtained using the relation :

T = rF * sinθ

T = 0.15 * 30 * sin(45)

T = 0.15 * 30 * 0.7071067

T = 3.18198015

T = 3.18 Nm

A road map is an example of a graphical model. Correct option is A.

A road map is an example of a graphical model because it represents real-world information using graphical elements, such as lines, symbols, colors, and labels, to convey spatial relationships and information about roads, landmarks, and geographical features. Graphical models are visual representations that help convey complex information in a simplified and easily understandable way.

In the case of a road map, it uses graphical elements to represent various features of a geographic area, such as highways, streets, intersections, bodies of water, cities, and points of interest. These graphical representations allow users to quickly understand the layout of roads, distances between locations, and how to navigate from one place to another.

Graphical models are particularly effective for representing spatial and visual information, making them an essential tool for tasks like navigation, planning trips, and understanding geographical relationships.

The acceleration of the object is 5 m/s^2 while the speed is 160 m

Let us note that we have to know that the acceleration of the car is the rate of the change of the velocity of the  car with timer and so we can then be able to write for this problem that;

a = v - u/t

a = acceleration

v = final velocity

u = initial velocity

t = time taken

a = 40 - 0/8

= 5 m/s^2

Then we have that;

v^2 = u^2 + 2as

s = v^2- u^2/2a

s = (40^2 - (0)^2/2 * 5

If a person pushed on the door to the left of the handle, they would need to use less force than if they used the handle.

The reason for this is that the handle provides a mechanical advantage over pushing directly on the door. When the handle is used, the force applied to it is multiplied by the mechanical advantage, which is the ratio of the distance through which the handle moves to the distance through which the door moves.

For example, if the handle moves the door a distance of 2 cm and the door moves a distance of 5 cm when pushed directly on it, the mechanical advantage is 2:5, or 0.4. This means that for every 0.4 units of force applied to the handle, the door moves 1 unit.

On the other hand, if the person pushed directly on the door, the force applied to it would be the same as the force applied to the door, without any mechanical advantage. In this case, the door would move 5 cm, not 2 cm, for every unit of force applied to it.

Therefore, the person would need to use more force if they pushed directly on the door than if they used the handle, because they would have to apply the same amount of force over a greater distance to move the door the same distance.

The thicker wire has one-fourth the resistance of the thinner wire.

The characteristic of a substance that prevents the flow of current is known as resistance. The free electrons begin to move in a specific direction when a voltage is applied across the conductor. These electrons collide with atoms or molecules as they move, creating heat in the process. These atoms or molecules prevent free electrons from moving through a substance. Resistance is represented by the symbol R.

Specific resistance is another name for resistivity. A substance with certain dimensions, such as one meter in length and a cross-sectional area of one square meter, has a resistance that is represented by its resistivity. Resistivity or specific resistance is represented by ρ.

The relation between resistance R and resistivity ρ is given as:

                                              R = ρL/A

where,

R = resistance of the conductor

ρ =  resistivity of the material

L = length of the conductor

A = cross-sectional area of the conductor

Given,

r₁ = 2r₂

L₁ = L₂

where

r₁ = radius of the first conductor

r₂ = radius of the second conductor

L₁ = length of the first conductor

L₂ = length of the second conductor

To find

R₁/R₂ =?  (the ratio of R₁ and R₂)

If the radius is twice the other then the area will become,

A₁ = π r₁²

A₂ = π r₂²

A₁ = π (2r₂)²

   = 4π r₂²

Therefore,

A₁ = 4 A₂

Now put the values in the formula,

R = ρL/A

R₁/R₂ = ρ L₁ A₂/  ρ L₂ A₁

R₁/R₂ = L A₂/ L (4A₂)

R₁/R₂ = 1/4

R₁ = R₂/4

Hence, the thicker wire with twice the radius of the thin wire has one-fourth the resistance of the thinner wire.

I understand the question you are looking for is this:

How do the resistances of two conducting wires compare if they have the same length, but one is twice the radius of the other?

(a) The thicker wire has half the resistance of the thinner wire

(b) The resistance is the same in both wires

(c) The thicker wire has one-fourth the resistance of the thinner wire

(d) The thicker wire has twice the resistance of the thinner wire.

Explanation:

According to snell's law , if i be the angle of incidence and r be the angle of refraction

sin i / sin r = 1.33 / 2.42

sin i / sin r = .55

Hence sin r > sin i

r > i

In other words angle of refraction will be more than angle of incidence . So, the ray will bend away from the normal .

Explanation:

According to Newton's law of cooling, The formula that models the cooling of the turkey is T(t) = (165 - 75) * e^(k * t) + 75. The temperature of the turkey 50 minutes after it leaves the oven will be approximately 118°F.

(a) The formula that models the cooling of the turkey is T(t) = (165 - 75) * e^(k * t) + 75.

In this case, the temperature difference between the turkey and the room, when it came out of the oven, is A = 165 - 75 = 90°F, and Ts (the temperature of the room) is 75°F. By substituting these values into the equation T(t) = A * e^(k * t) + Ts, we get T(t) = 90 * e^(k * t) + 75.

To find the value of k, we can use the information that when t = 30 minutes, T(30) = 145°F. Substituting these values into the equation and solving for k, we have 145 = 90 * e^(k * 30) + 75. Rearranging and solving, we find k ≈ -0.0207.

(b) The temperature of the turkey 50 minutes after it leaves the oven will be approximately 118°F.

To calculate the temperature at t = 50 minutes, we can use the formula T(t) = 90 * e^(-0.0207 * t) + 75. Substituting t = 50, we have T(50) = 90 * e^(-0.0207 * 50) + 75. Evaluating this expression, we find T(50) ≈ 118°F.

(c) It will take approximately 145 minutes for the turkey to cool to 110°F.

To determine the time it takes for the turkey to reach a temperature of 110°F, we can rearrange the equation T(t) = 90 * e^(-0.0207 * t) + 75 and solve for t. So, 110 = 90 * e^(-0.0207 * t) + 75. Solving this equation, we find t ≈ 145 minutes.

Answer:

–0.11 N.

Explanation:

From the question given above, the following data were obtained:

Mass (m) = 6.1 g

Initial velocity (u) = 350 m/s

Time (t) = 0.32 mins

Final velocity (v) = 0 m/s

Force (F) =?

Next, we shall convert 0.32 mins to seconds. This can be obtained as follow:

1 min = 60 s

Therefore,

0.32 mins = 0.32 × 60 = 19.2 s

Next, we shall determine the acceleration of the the bullet. This can be obtained as follow:

Initial velocity (u) = 350 m/s

Time (t) = 19.2 s

Final velocity (v) = 0 m/s

v = u + at

0 = 350 + (a × 19.2)

0 = 350 + 19.2a

Collect like terms

0 – 350 = 19.2a

–350 = 19.2a

Divide both side by 19.2

a = –350 / 19.2

a = –18.23 m/s²

Next, we shall convert 6.1 g to Kg.

1000 g = 1 Kg

Therefore,

6.1 g = 6.1 g × 1 Kg / 1000 g

6.1 g = 0.0061 Kg

Finally, we shall determine the force. This can be obtained as follow:

Mass (m) = 0.0061 Kg

Acceleration (a) = –18.23 m/s²

Force (F) =?

F = ma

F = 0.0061 × –18.23

F = –0.11 N

NOTE: The negative sign indicates that the force is in opposite direction.

Since the angle of reflection is congruent to the angle of incidence, we have r1 = i1 = 38.2°.

Now, let's calculate angle x, knowing that it is complementary to the angle r1:

To calculate angle y, let's add all angles in the triangle and equate the sum to 180°:

Angles i2 and y are complementary, so we have:

Since r2 and i2 are congruent, so the angle of reflection in the second mirror is 15.5°.
