Answer:

1620000J

Explanation:

Given parameters:

Power = 180000W

Time  = 9s

Unknown:

Work done by the engine = ?

Solution:

Power is the rate at which work is being done.

 Now,

        Power  = \(\frac{Work done }{time}\)  

 Work done  = Power x time taken

 Work done  = 180000 x 9  = 1620000J

The resulting changes will be:

1. Pressure head: 88 ft (or 26.82 m)

2. Effective stress: No change, assuming no other factors affect it

3. Fluid pressure: No change

4. Total stress: Decreased by the same amount as the effective stress

To calculate the effective stress in the aquifer, we need to subtract the fluid pressure from the total stress.

Given:

Pressure head in the aquifer = 100 ft (or 30.48 m)

The pressure head in the aquifer is directly proportional to the fluid pressure, which can be calculated using the formula:

Fluid pressure (P) = ρ * g * h

Where:

ρ = density of the fluid (water) = approximately 1000 kg/m³

g = acceleration due to gravity = 9.8 m/s²

h = pressure head

Fluid pressure = 1000 kg/m³ * 9.8 m/s² * 30.48 m ≈ 298,440 N/m² (or Pa)

The total stress in the aquifer is the sum of the fluid pressure and the effective stress. Therefore, the effective stress can be calculated by subtracting the fluid pressure from the total stress.

Now, let's consider the changes in the hydraulic head due to pumping:

Change in hydraulic head = -12 ft (or -3.66 m)

The resulting changes in each parameter will be as follows:

1. Pressure head:

The pressure head will be reduced by 12 ft, so the new pressure head will be 100 ft - 12 ft = 88 ft (or 26.82 m).

2. Fluid pressure:

The fluid pressure does not change, as it depends on the density of the fluid and the acceleration due to gravity, which remain constant.

3. Effective stress:

The effective stress can be calculated as the total stress minus the fluid pressure. Since the fluid pressure remains constant, the effective stress will also remain constant unless there are other factors affecting it.

4. Total stress:

The total stress is the sum of the fluid pressure and the effective stress. As mentioned earlier, the fluid pressure remains constant, so the total stress will decrease by the same amount as the effective stress, assuming no other factors affect the total stress.

Therefore, the resulting changes will be:

1. Pressure head: 88 ft (or 26.82 m)

2. Effective stress: No change, assuming no other factors affect it

3. Fluid pressure: No change

4. Total stress: Decreased by the same amount as the effective stress

Answer:

50 Newtons

Explanation:

A body with a mass of 10 kg is moving with an acceleration of 5 m/s. What is the amount of force acting on it? The frictional force is 50N.

The force required to move vertically upward is 75N.

How are acceleration and force related?

The formula required to calculate force is mass x acceleration. This means that force is mass times acceleration i.e., those objects which has larger mass will require stronger force to move with the same acceleration as compared to object with smaller mass. This is the Newton’s second law of motion.

Weight of the body = 50 N

mg= 50 N

mx10= 50

m= 50/10= 5 kg

Fext = ma

F-50 = 5x 5

F= 25+50= 75 N .

The correct answer is: Its average speed was 50 m.p.h, its displacement was 100 miles, and its average velocity was zero.

We can calculate the car's average speed by using the formula:

average speed = total distance traveled / total time taken

The total distance traveled is the difference between the final and initial odometer readings:

total distance traveled = 123 miles - 23 miles = 100 miles

The total time taken is 2 hours.

average speed = 100 miles / 2 hours = 50 m.p.h.

Since the car returned to its starting point, its displacement is zero. Displacement is a vector quantity that refers to the change in position of an object from its initial position to its final position. In this case, the car ended up at the same position as it started, so its displacement is zero.

Average velocity is defined as displacement divided by the total time taken. Since the displacement is zero, the average velocity is also zero, regardless of the car's speed during the trip.

The distance to open fire, based on the given parameters, is approximately 267 meters.

What is distance?

Distance is a scalar quantity that refers to the extent of space between two points or objects. It is a measurement of how far apart two locations or objects are from each other.

To calculate the distance at which the enemy's eyes are just resolvable by your pupil, we can use the concept of angular resolution. The formula for angular resolution is:

θ = 1.22 * (λ / D)

In this case, the diameter of the target's eye (s) is given as 2.5 cm, which is equivalent to 0.025 m. The diameter of the pupil (D) is given as 4.9 mm, which is equivalent to 0.0049 m. The wavelength of light (λ) is given as 555 nm, which is equivalent to 555 × 10⁻⁹ m.

Substituting these values into the formula, we can solve for the angular resolution (θ). Once we have the angular resolution, we can use basic trigonometry to calculate the distance (d) at which the target is located:

d = (s / 2) / tan(θ)

By plugging in the values, we find that the distance at which the target is when you open fire is approximately 267 meters.

Dragging the axis to 0° on the SPACE tab will result in no transitional seasons, and the entire Northern Hemisphere will experience either continuous daylight (summer) or continuous darkness (winter), depending on the time of year.

When you drag the axis on the SPACE tab to 0°, it aligns the Earth's rotational axis perpendicular to the plane of its orbit around the sun. This means that the Earth's North Pole is pointing directly towards the sun, and the South Pole is pointing away from it.

On the EARTH tab, this change in the orientation of the Earth's axis will affect the seasons in the following ways

The summer solstice occurs around June 21st in the Northern Hemisphere when the North Pole is tilted towards the sun. However, when you drag the axis to 0°, the North Pole is pointing directly towards the sun, so the entire Northern Hemisphere experiences continuous daylight, and it is summer everywhere in the Northern Hemisphere.

The winter solstice occurs around December 21st in the Northern Hemisphere when the North Pole is tilted away from the sun. However, when you drag the axis to 0°, the North Pole is pointing directly away from the sun, so the entire Northern Hemisphere experiences continuous darkness, and it is winter everywhere in the Northern Hemisphere.

The equinoxes occur around March 21st and September 21st in the Northern Hemisphere when the axis is neither tilted towards nor away from the sun.

If a coleoptile tip is covered with a blackened glass tube and illuminated from the side, the coleoptile will **bend toward the light**.

Coleoptiles are protective sheaths that cover the emerging shoots of monocot plants, such as grasses. They exhibit a phenomenon called phototropism, where they bend towards a light source. When the coleoptile tip is covered with a blackened glass tube, it prevents light from reaching the tip directly. However, when the coleoptile is illuminated from the side, light will still be perceived by the side of the coleoptile that is not covered by the tube.

The coleoptile exhibits a growth response called positive phototropism, which means it bends towards the light source. This bending is due to the differential elongation of cells on the shaded side of the coleoptile, resulting in a bending motion towards the light. Therefore, in this scenario, the coleoptile will bend towards the light despite the presence of the blackened glass tube.

The complete question is given below:

Gas pressure is caused by gas molecules colliding with surfaces.

When gas molecules move and collide with the walls of a container, they exert a force on the walls, which causes the pressure of the gas in the container.

This is why gas pressure is often measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa). While barometers can be used to measure gas pressure indirectly by measuring atmospheric pressure, the underlying cause of gas pressure is the collision of gas molecules with surfaces.

On clear, sunny days, the difference in surface wind speed between morning and afternoon is greater than on cloudy, overcast days due to the variation in atmospheric stability between morning and afternoon.

On sunny days, the earth's surface heats up rapidly in the morning, leading to the formation of a stable radiation inversion where the air near the surface is cooler and denser than the air above.

As the day progresses, the surface continues to warm up, and the atmosphere becomes increasingly unstable due to convective mixing. This instability leads to stronger surface winds as air is forced to move from areas of high pressure to areas of low pressure.

On overcast days, the clouds act as a barrier to incoming solar radiation, which reduces the amount of heating at the earth's surface. As a result, the atmosphere is more stable, and there is less vertical mixing, leading to weaker surface winds.

The stable atmosphere also tends to trap pollutants near the surface, leading to poorer air quality in urban areas. Therefore, the difference in surface wind speed between morning and afternoon is typically greater on a clear, sunny day than on a cloudy, overcast day.

Δt = The time the block is in contact with the spring

Therefore;

\(\Delta t = \dfrac{F_{NET}}{\Delta p}\)
