The number of seconds that the dive will take if peregrine falcon dove at its maximum speed for half a mile is 9 seconds.

From the complete information, it was stated that the peregrine falcon can reach speed of up to 200 miles per hour.

Therefore, the number of seconds that the dice would take for half a mile will be calculated thus:

1 hour = 200 miles

3600 seconds = 200 miles

1 second will be: = (200/3600) = 0.056 miles

Therefore, the time will be:

200miles / 1 hour = 0.x

x = 0.0025 hours

Therefore, 0.0025 hours will be:

= 0.0025 × 3600

= 9 seconds.

The work done by the man pushing the car over the given distance is 1000J.

Given the data in the question;

Work done; [tex]W = \ ?[/tex]

Work done is simply defined as the energy transfer that takes place when an object is either pushed or pulled over a certain distance by an external force. It is expressed as;

[tex]Work\ done = f * d[/tex]

Where f is force applied and d is distance travelled.

To determine the work done by the man, we first solve for the force applied F.

From Newton's Second Law; [tex]Force \ F = m * a[/tex]

We substitute our given values into the expression

[tex]F = m * a \\\\F = 200kg * 0.5m/s^2\\\\F = 100kg.m/s^2[/tex]

Next we substitute our values into the expression of work done above.

[tex]Work \ done = f * d\\\\Work \ done = 100kg.m/s^2 * 10m\\\\Work \ done = 1000kgm^2/s^2\\\\Work \ done = 1000J[/tex]

Therefore, the work done by the man pushing the car over the given distance is 1000J.

Kelvin is the only temperature scale that when it hits 0, the universe would be frozen. it is the lowest possible temperature.

(a) The wavelength of the resonance created is 0.8 m.

(b) The speed of the sound in the fundamental mode is 400 m/s.

(c) The low value of speed of speed of sound in water calculated may be as a result of low temperature of the water poured into the cooking pot.

The wavelength of the resonance created is determined by assuming the cooking pot to be a closed pipe.

Wavelength of fundamental mode of a closed pile = 4L

where;

λ = 4 x 0.2 = 0.8 m

The speed of the sound in the fundamental mode is calculated as follows;

v = fλ

v = 500 x 0.8

v = 400 m/s

Sound wave is directly proportional to temperture, as the temperature of the water increases, the speed of sound increases as well.

The low value of speed of speed of sound in water calculated may be as a result of low temperature of the water poured into the cooking pot.

weight-44.1 kg- mass-4.5kg gravity-9.8 formula-(see explanation)

Explanation:

force/weight on earth is = mass x gravitational field strength

In a circuit, if the resistors were decreased by a factor of 1,000, it is true that the current would increase by a factor of 1,000, according to Ohm's Law.

It is a law in electricity that posits that the voltage that goes through a conductor is directly proportional to the current.

One formula in Ohm's law is:

Voltage = Current x Resistance

If the resistance were to decrease by a factor of 1,000, the current would have to increase by a factor of 1,000 as well in order to give the same voltage.

Answer: It is minimising

For minimizing, the error is calculated by finding the sum of the squared distance between actual and predicted values.

The difference between the measured and analysis of the financial statements might well be defined as an error. For instance, if the two operators use the same complete and precise tool.

We have:

For ____________, the error is calculated by finding the sum of the squared distance between actual and predicted values

The correct answer is minimizing because according to the information provided in the problem. The sum of squared distance between actual and anticipated values is calculated to "minimize" the mistake.

This is one of the most significant aspects of statistics, and it involves mathematical computations involving error calculations for various values.

Thus, for minimizing, the error is calculated by finding the sum of the squared distance between actual and predicted values.

Answer:

B buoyant force (mass) = 600 - 400 = 200 g       (I)

upthrust is 200 g due to decrease in apparent body weight

(Note that g is being treated as force here when it is actually mass)

D = M / V     definition of density

since density of water is 1 (1 g / cm^3)

from (I) the equivalent volume of water is 200 cm^3 since the upthrust will equal the weight of the water displaced

Relative density of solid is 600 g / 200 g = 3     (weight of solid vs the weight of the water displaced

D = 3 g / cm^3       density of solit
