Inertia has an impact on both moving and stationary objects, according to Newton's first law of motion. Unless an unbalanced force is acting on an object, Newton's first law states that it will stay at rest or move in a straight line at a constant speed.

What is inertia?

Iners, which means idle or slow in Latin, is where the word inertia originates. Any physical object's resistance to a change in velocity can also be referred to as having inertia. Changes in the object's motion's speed or direction fall under this category. This trait includes the propensity for objects to continue going straight ahead at a constant pace in the absence of external pressures. Mass, a quantitative characteristic of physical systems, manifests itself primarily in inertia. One of the pillars of traditional physics is the concept of inertia.

It is still utilized today to describe how objects move and are impacted by external forces.

Answer:

3.75 hours

Explanation:

By \(v = \frac{d}{t}\)

where v is the velocity (or speed in this case)

d is the distance travelled

t is the time taken

\(t = \frac{150}{40}=3.75\)
Therefore it takes 3.75 hours for the bus to travel 150 km and 40 km/hr.

Answer:

If the boat is going 36 km/h, then it will take about 5.8 hours to travel a distance of 210 km/h.

Explanation:

To calculate time, you have to divide the distance by the speed.

In this case, we take 210 and divide it by 36. The answer you will get is 5.83...

Time = (distance) / (speed)

Time = (210 km) / (36 km/hr)

Time = 5.833 hours

The pressure will be different because of the difference in the masses of horse A and horse B.

Horse A will have greater pressure due to much bigger mass.

In order for a horse to survive and operate, its hooves are necessary. Throughout a horse's lifetime, its hooves expand. Each foot of a horse has a single, solid hoof. The size of this might vary according on the breed, size, and running and jumping prowess of the horse.

Scholars have long disagreed on how animals—whose predecessors were dog-sized creatures with three or four toes—came to have only one hoof. According to a recent research, when horses grew bigger, one big toe was shown to be more resistant to bone stress than several smaller toes.

The rotational speed of the motor 3 in rpm. b. 92

The figure shows a hydraulic circuit that uses three chain conveyors. The torque that drives the motors is T: =1500 N.m. T2 =700 Nm and, T3 = 300Nm.The volumetric flow rate produced by the pump is 6.3 liters per minute. The displacement volume of the motors is V01 =1000 cm3/rev. V02 =1000 cm3/rev and, V09 =500 cm3/rex.

The motors have a volumetric efficiency of 0.9 and an overall efficiency of 0.85. The leakage of hydraulic motors 1 and 3 is internal completely, while the leakage of hydraulic motor 2 is external completely.The orifice of the flow control valve has a diameter of 0.5 mm. The capacity coefficient of the needle valve is 0.7.

The pressure losses through the pipes are ignored. The volumetric flow rate through the needle valve is Q = C × A2 × ΔP / ρ where C is the capacity coefficient, A is the area of the orifice, ΔP is the pressure difference through the needle valve, and ρ is the density of the fluid. The density of the oil used in the hydraulic system is 860 kg/m3. We need to determine the rotational speed of motor 3 in rpm.

So,Let’s first determine the volumetric flow rate required by hydraulic motor 3. Using the expression of volumetric flow rate through the needle valve, we have Q = C × A2 × ΔP / ρ… (i)We are given that the capacity coefficient of the needle valve is 0.7. Its orifice diameter is 0.5 mm.

Hence, the area of the orifice is given byA2 = π d2 / 4where d is the diameter of the orifice. So, A2 = π × (0.5 mm)2 / 4 = 0.196 mm2 = 1.96 × 10-7 m2Using equation (i), we haveQ = C × A2 × ΔP / ρNow, we will calculate ΔP. To do this, we need to determine the flow rates Q1, Q2, and Q3.Let Q’ be the total volumetric flow rate through the system.

Since the overall efficiency of the system is given as 0.85, we haveQ’ = 0.85 × 6.3 l/min = 5.355 l/min = 5.355 × 10-3 m3/minWe know that the volume of fluid passing through the hydraulic motors is equal to their displacement volume multiplied by the number of revolutions per unit time.So, we haveQ1 = V01 × n1 … (ii)Q2 = V02 × n2 … (iii)Q3 = V03 × n3 … (iv)where V01, V02, and V03 are the displacement volumes of hydraulic motors 1, 2, and 3, respectively.

We are given that V01 = V02 = 1000 cm3/rev and V03 = 500 cm3/rev, which gives V01 = V02 = 1 × 10-6 m3/rev and V03 = 0.5 × 10-6 m3/rev.Substituting equations (ii), (iii), and (iv) in equation (i), we haveQ = C × A2 × (Q1 + Q2 - Q3) / ρSolving for Q3, we getQ3 = (Q1 + Q2 - Q) / C × A2 × ρPutting the given values in the above expression, we haveQ1 = V01 × n1 = (1 × 10-6 m3/rev) × n1Q2 = V02 × n2 = (1 × 10-6 m3/rev) × n2Q3 = V03 × n3 = (0.5 × 10-6 m3/rev) × n3Q = 5.355 × 10-3 m3/min = 5.355 × 10-3 / 60 m3/s = 8.925 × 10-5 m3/sA2 = 1.96 × 10-7 m2C = 0.7ρ = 860 kg/m3

Substituting the above values, we get8.925 × 10-5 = (1 × 10-6 × n1 + 1 × 10-6 × n2 - 0.5 × 10-6 × n3) / (0.7 × 1.96 × 10-7 × 860)Solving for n3, we have n3 = 91.6 rpmSo, the correct option is b. 92.

The net change in thermal energy of the air in the cylinder is -8.8 J.

When a force is exerted on a system and it undergoes a displacement, work is done. In this case, when the pump handle moves 0.24 m, the work done on the air in the cylinder is:

Work = Force x Distance

Work = 45N x 0.24m

Work = 10.8 J

The heat leaving the cylinder through the walls is considered as heat transfer or heat loss to the surroundings.

Therefore, the net change in thermal energy of the air in the cylinder can be calculated using the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system:

ΔU = Q - W

where ΔU is the change in internal energy of the system, Q is the heat added to the system, and W is the work done by the system.

Substituting the values given in the problem:

ΔU = 2.0 J - 10.8 J

ΔU = -8.8 J

Since the value of ΔU is negative, it means that the internal energy of the air in the cylinder has decreased, which can be attributed to the heat loss to the surroundings.

The chi-square test assumes that the variables being analyzed are measured at a nominal or ordinal level of measurement.

In statistics, the level of measurement refers to the nature and properties of the data being collected. There are four levels of measurement: nominal, ordinal, interval, and ratio. Nominal and ordinal levels are considered categorical, while interval and ratio levels are considered numerical. The chi-square test is specifically designed for analyzing categorical data, where the observations can be classified into distinct categories or groups. It is used to determine whether there is a significant association or relationship between two categorical variables.

The test calculates the difference between the observed frequencies and the expected frequencies under the assumption of independence between the variables. It compares the observed and expected frequencies using a chi-square statistic and determines the p-value to assess the statistical significance of the association. Therefore, the chi-square test assumes that the variables being analyzed are measured at a nominal or ordinal level because it deals with categorical data and evaluates the relationship between different categories or groups.

Answer:

A) d_o = 20.7 cm

B) h_i = 1.014 m

Explanation:

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

1/f = 1/d_o + 1/d_i

Where;

f is focal Length = 20 cm = 0.2

d_o is object distance

d_i is image distance = 6m

1/0.2 = 1/d_o + 1/6

1/d_o = 1/0.2 - 1/6

1/d_o = 4.8333

d_o = 1/4.8333

d_o = 0.207 m

d_o = 20.7 cm

B) to solve this, we will use the magnification equation;

M = h_i/h_o = d_i/d_o

Where;

h_o = 3.5 cm = 0.035 m

d_i = 6 m

d_o = 20.7 cm = 0.207 m

Thus;

h_i = (6/0.207) × 0.035

h_i = 1.014 m

Pieces of burning vegetation that are spread by air currents and spread downwind are known as "brands."

When a wildfire occurs, burning vegetation can release embers or pieces of burning material into the air. These embers, often called "brands," can be carried by air currents and spread downwind, potentially igniting new fires and causing the fire to spread rapidly.

Brands are a significant concern during wildfires as they can travel long distances and start spot fires ahead of the main fire front. Factors such as wind speed, direction, and the flammability of surrounding vegetation determine how far brands can travel and how quickly they can ignite new fires.

Firefighters and fire management personnel closely monitor and address brands during firefighting operations to prevent the further spread of the fire. Controlling and extinguishing spot fires caused by brands is crucial in minimizing the overall impact and size of a wildfire.

Answer:

27.82m

Explanation:

The distance of the cyclist can be calculated using the formula:

S = ut + 1/2 (at^2)

Where; S = distance

u = initial velocity

a = acceleration

t = time

However, to find acceleration, we use:

a = v - u/t, where v is the final velocity

According to this question, u = 4.2m/s, v = 6.3m/s, t = 5.3s

a = 6.3 - 4.2 / 5.3

a = 2.1/5.3

a = 0.396m/s^2

Hence, using S = ut + 1/2 (at^2)

S = (4.2 × 5.3) + 1/2 (0.396 × 5.3 × 5.3)

S = 22.26 + 5.56

S = 27.82

Therefore, the cyclist travel in 27.82m
