Answer:

A

Explanation:

Answer:

2667 N

Explanation:

We can solve this problem by using the impulse formula.

We have three known variables, so we can solve for the fourth: F.

Divide Δt from both sides to isolate F.

Substitute known values into the equation.

The force that the car's tires exert on the road is 2667 N.

The force that the car's tires exert on the road is equivalent to the force that the road exerts on the car due to Newton's Third Law of Motion.

We can calculate the force that the car's tires exert on the road by using the formula F = ma, which was derived from Newton's Second Law of Motion.

We are given the mass of the car, velocity of the car, and the time in which it accelerated.

We can use this equation for acceleration:

The car started from rest, meaning it had an initial velocity of 0 m/s. Its final velocity was 10 m/s. The time that it took for the car to go from 0 m/s to 10 m/s was 4.5 seconds.

Now we have two known variables, mass and acceleration. We can solve for the force exerted on the car (and thus, the force the car exerts on the road) using the formula F = ma.

The force that the car's tires exert on the road is 2667 N.

Answer: The conditions would probably exist the drew point and dry bulb temperatures to be the same at the ground because When the dew point temperature and air temperature are equal, the air is said to be saturated. Dew point temperature is NEVER GREATER than the air temperature. Therefore, if the air cools, moisture must be removed from the air and this is accomplished through condensation.

Explanation:

Since the air is said to be saturated when the dew point temperature and air temperatures are equal, the circumstances are likely present for the dew point and dry bulb temperatures to be equal at the ground. NEVER is the dew point temperature higher than that of the air temperature. As a result, condensation is used to remove moisture from the air when it cools.

The dew point, under the assumption of constant air pressure and water content, is the temperature at which air must be chilled to become water vapor condenses. Airborne vapor will condense to create liquid water, known as dew, when it is cooled below the dew point, thereby moisture capacity.  If this occurs via coming into contact with a cooler surface, dew will grow there.

Humidity influences the dew point. The dew point rises as the amount of moisture in the atmosphere increases.

Answer:

A) f_o ≈ 836.9 Hz

B) f ≈ 765 Hz

Explanation:

A) To solve this, we will use the formula;

f_o = (v•f_s)/(v - v_p)

Where;

v is speed of sound in air

f_s is frequency of source

v_p is the speed of the person moving towards the whistle.

We are given;

v = 340.6 m/s

v_p = 15 m/s

f_s = 800 Hz

Thus;

f_o = (340.6 × 800)/(340.6 - 15)

f_o ≈ 836.9 Hz

B) to solve this, let's first calculate the wavelength from the formula;

λ = v/f_s

λ = 340.6/800

λ = 0.42575 m

To get the frequency he will hear after passing the factory, we will use the formula;

f = (v - v_p)/λ

f = (340.6 - 15)/0.42575

f ≈ 765 Hz

Answer:

4 rolls

Explanation:

The probability of rolling a 6 is 1/6 = 0.1667 (4.d.p)

This means that approx. 1/6 of the dice will land on a 6.

If the student removes a 1/6 of the dice each time, it means that the number of dice is decreasing by 1/6 each roll (or multiplying by 5/6).

114/2 = 57

By multiplying 114 by 5/6 and continuing we can see how many times it takes for us to get past 57.

Roll 1: 114 x 5/6 = 95

Roll 2: 95 x 5/6 = 79.17

Roll 3: 79.17 x 5/6 = 65.97

Roll 4: 65.97 x 5/6 = 54.98

Most likely to take 4 rolls before halving the number of dice.

You could also solve this problems by writing an equation and solving using logs but I think this method is easier to understand.

For the wood crate to move, the force applied (minimum horizontal force) must be greater than the static friction between the wood crate and the wood floor

Given that Jim wishes to push a 100. N wood crate across a wood floor.

The weight of the wood = 100N

The weight will produce a normal reaction N which is equal in magnitude to the magnitude of the weight. That is,

N = mg = 100N

For the wood crate to move, the force applied must be greater than the static friction between the wood crate and the wood floor.

Static friction = μN

Where μ = static friction.

Therefore, the minimum horizontal force that would be required to start the crate moving depend on the nature of the surface of the wood floor.

t = 11.1 hours

Explanation:

The question says that, "A mobile advances at 20 m / s and travels a distance of 800 km. Determine the time in hours you use".

Given that,

Speed of a mobile, v = 20 m/s = 72 km/h

Distance, d = 800 km

We know that,

Speed = distance/time

So,

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{800}{72}\\\\t=11.1\ h[/tex]

So, it will take 11.1 hours.

Explanation:

Not all plants can grow flowers. Only the ones thay have buds can.

Not all plants produce flowers. Hence, this is the characteristic which is not common in all plants.Therefore, the correct option is 4.

Flowers are the structures of plants. They are responsible for producing seeds that will grow into new plants. Flowers typically consist of a colorful or ornamental part called the corolla, which attracts pollinators such as bees and butterflies, and a reproductive part called the stamen and pistil, which contain the plant's male and female organs.

Not all green plants produce flowers. Flowering plants are a type of plant that belong to the group Angiosperms, but there are also non-flowering plants like ferns and mosses that do not produce flowers. Therefore, the correct option is 4.

Answer:

v₁ = 1.78 m/s

Explanation:

We can use the law of conservation of momentum here, as follows:

[tex]m_1u_1 + m_2u_2 = m_1v_1 + m_2v_2[/tex]

where,

m₁ = mass of first object = 4.5 kg

m₂ = mass of second object = 6.2 kg

u₁ = initial speed of first (smaller) mass = 16 m/s

u₂ = initial speed of second (larger) mass = 0 m/s

v₁ = final speed of first (smaller) mass = ?

v₂ =  final speed of second (larger) mass = 10 m/s

Therefore,

[tex](4.5\ kg)(16\ m/s)+(6.2\ kg)(0\ m/s)=(4.5\ kg)(v_1)+(6.2\ kg)(10\ m/s)\\70\ kgm/s - 62\ kgm/s = (4.5\ kg)v_1\\\\v_1 = \frac{8\ kgm/s}{4.5\ kg}\\\\[/tex]

v₁ = 1.78 m/s

Answer:

The frequency is 0.25Hz and the period is 4s

Explanation:

To solve this we can use the formula: [tex]f = \frac{v}{\lambda}[/tex], where f=frequency, v=velocity and lambda = wavelength.

In the question, we are given the information that the velocity of the wave is 6.5m/s and the wavelength is 26 meters long. By putting these values into the formula, we can find the frequency:

[tex]f=\frac{6.5}{26} \\f= 0.25Hz[/tex]

Period is the inverse of frequency: [tex]T=\frac{1}{f}[/tex]

Therefore the period is: [tex]T = \frac{1}{0.25} \\T = 4s[/tex]

Answer:

d) 105 s

Explanation:

Given the following data;

Distance A (length of train) = 100 m

Velocity = 72 km/h to meters per seconds = 72 * 1000)/3600 = 72000/3600 = 20 m/s

To find the time;

Time = distance/speed

Time = 100/20

Time = 5 seconds.

II. When the distance (bridge) is 2km;

Distance B = 2km = 2*1000 = 2000 meters

Time = distance/speed

Time = 2000/20

Time = 100 seconds

Therefore, total time = 5 + 100 = 105 seconds

Answer:

(1) The gravitational forces are inversely proportional to the square of the distance between the objects. More is the distance between the objects , less will be the gravitational force between them.

(2) The gravitational forces are the weakest of all the four fundamental forces (Nuclear forces, weak forces, electromagnetic forces, gravitational forces) in nature.

(3)Gravitational forces are always attractive . They are also conservative in nature. work done by these forces or against these forces doesn't depend on the path followed.

Answer:

a)It is NOT possible using this telescope, to see the two stars as separate stars

b)[tex]d_{min} =28.466m[/tex]

Explanation:

From the question we are told that:  

Diameter of lens,[tex]d = 25 cm \approx 0.25 m[/tex]

Distance from both star [tex]D_f= 2*10^{17} m[/tex]

Distance between both stars [tex]D_b= 6*10^9 m[/tex]

Wavelength of light [tex]\lambda =700 nm \approx 700*10^-9 m[/tex]

Generally the equation for angle subtended by the two stars at the lens  is mathematically given by

 [tex]\theta=\frac{D_f}{D_b}[/tex]

 [tex]\theta=\frac{6*10^9}{2*10^{17}}[/tex]

 [tex]\theta=3.0*10^{-8} rad[/tex]

Generally the equation for minimum angular separation of two object is mathematically given by

[tex]\theta_{min} = 1.22*\lambda/d[/tex]  

[tex]\theta_{min}= \frac{1.22*700*10^-9}{0.25}[/tex]  

[tex]\theta_{min}= 3.416*10^-^6 rad[/tex]

Therefore

 [tex]\theta < \theta_{min}[/tex]

[tex]3.0*10^{-8} rad< 3.416*10^-^6 rad[/tex]

It is NOT possible using this telescope, to see the two stars as separate stars

b)

Generally the equation for minimum diameter of the lens is mathematically given by

  [tex]d_{min} =\frac{ 1.22*\lambda}{\theta}[/tex]

  [tex]d_{min} =\frac{ 1.22*700*10^{-9}}{3*10^{-8}}[/tex]

  [tex]d_{min} =28.466m[/tex]
