48. What causes divide underflow, and what can be done about it?

Answer:

a) 2·√10 seconds

b) Linda should be approximately 30.6 meters

c) Jenny's speed at the 100-m mark is approximately 6.325 m/s

Explanation:

The speed with which Linda is running = 8.6 m/s

The point Jenny starts = The 80-m mark

The acceleration of Jenny = 1.0 m/s²

a) The time it takes Jenny to run from the 80-m mark to the 100-m mark, t, is given as follows

Δs = u·t + (1/2)·a·t²

Δs = Distance = 100-m - 80-m = 20-m

u = The initial velocity of Jenny = 0

a = Jenny's acceleration = 1.0 m/s²

∴ 20 = 0×t + (1/2) × 1 × t² = t²/2

20 = t²/2

t = √(20 × 2) = 2·√10

The time it takes Jenny to run from the 80-m mark to the 100-m mark = 2·√10 seconds

b) The distance Linda runs in t = 2·√10 seconds, d = v × t

Given that Linda's velocity, v = 8.6 m/s, we have;

d = 8.0 × 2·√10 = 16·√10

The distance Linda runs in t = 2·√10 seconds = 16·√10 meters ≈ 50.6 meters

Therefore, Linda should be approximately (50.6 - 20) meters = 30.6 meters behind Jenny when Jenny starts running

c) Jenny's speed at the 100 m mark is given as follows;

v = u + a·t

t = 2·√10 seconds, a = 1.0 m/s², u = 0

∴ v = 0×t + 1.0×2·√10 = 2·√10 ≈ 6.325

Jenny's speed at the 100-m mark ≈ 6.325 m/s

Answer:

chemical potential energy

Explanation:

When the sun's radiant energy falls on Earth's oceans, it causes water to change state by evaporating. The form of energy water vapor have is chemical potential energy. when heat energy of sun falls on water surface, its state change from liquid to gas. This gas rises above in the form of water vapor. Its a chemical change. If this vapor get condense/ cool, it will turn into liquid again. We can say that vapor has potential to transform into water again. Thus, the energy stored in water vapor is called chemical potential energy.

How much force must be applied to maintain constant velocity?

The force required to maintain a constant velocity is 79 N.

What will be the net force acting on the crate?

The net force on the crate will be zero. This is because the force of friction acting in the opposite direction of motion and the pulling force acting on the crate are equal.

What will be the acceleration?

If the net force acting on an object is zero, then the object will have zero acceleration. This is because acceleration is directly proportional to net force acting on an object. If the net force is zero, then the acceleration of the object will be zero too.

These factors contribute to physical and psychological harm, hinder access to opportunities and resources, and perpetuate systemic inequalities.

Marginalized individuals, such as people with disabilities, face unique challenges that can exacerbate the impact of trauma, discrimination, negative attitudes, and exclusion. Trauma experienced by individuals with disabilities may result from direct incidents or from the effects of living in a society that is not fully inclusive. Discrimination and negative attitudes towards people with disabilities can lead to social isolation, limited employment prospects, and reduced access to healthcare and education. This exclusion can have long-lasting effects on their mental health, self-esteem, and overall well-being. Similarly, individuals who identify as LGBTQ+ may also face trauma, discrimination, negative attitudes, and exclusion. LGBTQ+ individuals often encounter higher rates of bullying, harassment, and violence due to their sexual orientation or gender identity. These experiences can lead to psychological distress, anxiety, depression, and even post-traumatic stress disorder (PTSD). Discrimination and exclusion from healthcare, housing, employment, and social support systems further compound the challenges faced by LGBTQ+ individuals, hindering their ability to thrive and fulfill their potential.

In both cases, the impacts of trauma, discrimination, negative attitudes, and exclusion are far-reaching. They can contribute to a cycle of disadvantage, limiting opportunities for personal growth, social participation, and economic advancement.

The electric power input is approximately 22.73 kW.

The motor dissipates heat to the environment at a rate of 2.73 kW.

To determine the electric power input and the rate at which the motor dissipates heat to the environment, we can use the given information about the motor's shaft power output and efficiency.

Given:

Shaft power output (Pout) = 20 kW

Efficiency (η) = 88% = 0.88 (as a decimal)

OP = output power

IP = Input power

(a) Electric power input (Pin):

The efficiency of a motor is defined as the ratio of output power to input power. Mathematically, we can express this relationship as:

\(\[\text{{Efficiency}} (\eta) = \frac{{\text{{OP}}}}{{\text{{IP}}}}\]\)

Rearranging the equation, we can solve for the input power:

\(\[\text{{IP}} = \frac{{\text{{OP}}}}{{\text{{Efficiency}}}}\]\)

Substituting the given values:

\(\[\text{{IP}} = \frac{{20 \, \text{kW}}}{{0.88}}\]\)

Calculating the input power:

\(\[\text{{IP}} = \frac{{20 \times 1000}}{{0.88}} \, \text{W}\]\)

Converting to kilowatts:

\(\[\text{{IP}} = \frac{{20000}}{{0.88}} \, \text{W} = 22727.27 \, \text{W} \approx 22.73 \, \text{kW}\]\)

Therefore, the electric power input is approximately 22.73 kW.

(b) Rate of heat dissipation:

The rate at which the motor dissipates heat to the environment can be determined by calculating the difference between the input power and the shaft power output.

Rate of heat dissipation = Input power−Shaft power

Substituting the given values:

\(\[\text{{Rate of heat dissipation}} = 22.73 \, \text{kW} - 20 \, \text{kW}\]\)

Calculating the rate of heat dissipation:

\(\[\text{{Rate of heat dissipation}} = 2.73 \, \text{kW}\]\)

Therefore, the motor dissipates heat to the environment at a rate of 2.73 kW.

Answer :light

Explanation:  

A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light.

Answer: E = 5.004*10^(20) joules

Explanation:

We do not have a lot of information about the impact, so we can assume that the energy released on the impact was the kinetic energy of the large fragment.

Remember that the kinetic energy of an object of mass M that moves at a velocity V is:

K = (M/2)*V^2

in this case, we know that the speed (that is equivalent to the velocity) is:

V = 60,000 m/s

And the mass is:

M = 1.39*10^(11) kg

Then the kinetic energy of the large fragment was:

K = (1.39*10^(11) kg/2)*( 60,000 m/s)^2 = 5.004*10^(20) joules.

Then we could conclude that the energy released on the impact was:

E = 5.004*10^(20) joules

The objects meet after 2.033722438s, at a height 136.5334679m from the ground.

Explanation:

Call the object being dropped A and the object being thrown B.

When the objects meet, the time ('t') for both objects will be equal, and the sum of their distances will be equal to 156.8m.

Figure out the distance for A in terms of time, t:

s = ut + (1/2)at²

= 0t +(1/2)(9.8)t²

=4.9t²

Figure out the distance for B in terms of time, t:

s = ut + (1/2)at²

=(77.1)t + (1/2)(-9.8)t²

=77.1t - 4.9t²

We now adding the distances gives us 156.8, so can write:

(4.9t²) + (77.1t - 4.9t²) = 156.8

77.1t = 156.8

∴ t = 2.033722438s

To find the distances, plug in this value for t:

For A: 4.9t² → 20.26653209m

For B: 77.1t - 4.9t² → 136.5334679m

The objects will meet 155.2 meters below the top of the tower after 15.7 seconds.

The formula to calculate the time it takes for the object thrown upwards to return to the ground:

Time = 2 * Initial velocity / gravitational acceleration

Plugging in the values given in the question, you can calculate the time as follows:

Time = 2 * 77.1 m/s / 9.8 m/s^2 = 15.7 seconds

To determine when and where the objects meet, you can use the following formula to calculate the height of the object thrown upwards at any given time:

\(Height = Initial velocity * time - (1/2) * gravitational acceleration * time^2\)

Plugging in the time calculated above and the initial velocity and gravitational acceleration given in the question, you can calculate the height of the object at the time it returns to the ground as follows:

Height = 77.1 m/s * 15.7 s - (1/2) * 9.8 m/s^2 * (15.7 s)^2 = -1.6 meters

This means that the object thrown upwards returns to the ground 1.6 meters below the point where it was launched. The object dropped from the top of the tower will also have fallen a distance of 156.8 meters in the same amount of time, so the two objects will meet at a point 156.8 meters - 1.6 meters = 155.2 meters below the top of the tower

Birdman should fly at a speed of approximately 82.8 m/s (296.4 km/h) to hit the bucket.

To determine how fast Birdman should fly to hit the bucket, we need to calculate the time it will take him to travel the distance of 50m from the start of the field to the bucket while flying at a height of 66m. We can use the following equation:

Speed = distance/time

We can use this equation to find the time it will take Birdman to reach the bucket, and then use that time to find his speed.

We can use the Pythagorean theorem to find the distance because we know that the bucket is placed 50m from the start of the field and the height is 66m,

so distance = √(50^2 + 66^2) = √(2500 + 4356) = √6756.

Then we can use the distance and the known time to find the speed.

Note that this is only an estimation, as we are assuming that birdman flies at a constant speed, and there's no air resistance or any other factor.
