Answers

Density = mass / volume. For that particular fluid, Density = (10,000 gm)/(60 ml) = (166 and 2/3) gm per ml. (That's roughly 8 times the density of the most dense substance on Earth.)

The is a factor that's affected by changes in the independent variable

Answers

So we want to know what factor is affected by the changes of the independant variable. So if we have the form f(x)=x, x would be the independant variable and when we change the value of that variable we directly change the dependant variable, because the value of the dependant variable is dependant of the independant variable.

An 89 kg person climbs up a uniform 13 kg ladder. The ladder is 5.9 m long; its lower end rests on a rough horizontal floor (static friction coefficient 0.26) while its upper end rests against a frictionless vertical wall. The angle between the ladder and the horizontal is 52◦. Let d denote the climbing person's distance from the bottom of the ladder (see the above diagram). When the person climbs too far (d > dmax), the ladder slips and falls down (kaboom!). Calculate the maximal distance dmax the person will reach before the ladder slips. The acceleration of gravity is 9.8 m/s2.

Answers

Answer:

The maximum distance the person will reach before he slip is 1.82m.

A student kicks a football vertically upwards, causing the football to reach a maximum height of 40.0m before falling back to the ground. Determine all unknowns and answer the following questions. Neglect drag and the initial height and horizontal motion of the football.A) With what speed was the football kicked?
B) What was the football's total flight time?

Answers

Answer:

A. 28 m/s

B. 5.72 s

Explanation:

The following data were obtained from the question:

Maximum height (h) = 40 m

Acceleration due to gravity (g) = 9.8 m/s²

A. Determination of the initial velocity.

Maximum height (h) = 40 m

Acceleration due to gravity (g) = 9.8 m/s²

Velocity at maximum height (v) = 0 m/s

Initial velocity (u) =.?

v² = u² – 2gh (Ball is going against gravity)

0² = u² – (2 × 9.8 × 40)

0 = u² – 784

Collect like terms

0 + 784 = u²

784 = u²

Take the square root of both side

u = √784

u = 28 m/s

Thus, the ball was kicked with a velocity of 28 m/s

B. Determination of the time of flight.

We'll begin by calculating the time taken to reach the maximum height. This can be obtained as follow:

Velocity at maximum height (v) = 0 m/s

Initial velocity (u) = 28 m/s

Time taken to reach the maximum height (t) =?

v = u – gt (Ball is going against gravity)

0 = 28 – 9.8t

Rearrange

0 + 9.8t = 28

9.8t = 28

Divide both side by 9.8

t = 28/9.8

t = 2.86 s

Finally, we shall determine the the time of flight as follow:

Time taken to reach the maximum height (t) = 2.86 s

Time of flight (T) =?

T = 2t

T = 2 × 2.86

T = 5.72 s

Therefore, the time of flight for the ball is 5.72 s

The main purpose of the turbine in the turbojet engine is to A. drive the compressor.
B. reduce the temperature of the exhaust gas.
C. increase the velocity of the exhaust gases.
D. compress the air. ~IT is NOT D.

Answers

The correct answer is A. drive the compressor. It's not D because the compressor compresses it, not the turbine. The temperature and the velocity of gasses are unrelated to this. There are in fact two turbines, and the first one gets power from exhaustion, which is then used to power to turbine in the turbojet that is used to drive the compressor. This is how turbojets commonly work.
