Why can work out never be greater than work in? What would that do to efficiency?

Answers

Answer 1

Answer:

Explanation:

Work out can never be greater than work in because when work out is greater than work in, this means that more energy is being produced than what is being put into the system. This is not possible, as it would violate the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed.

If work out were greater than work in, this would lead to an increase in efficiency, as the system would be able to produce more energy than what is being put into it. However, this increase in efficiency would be unsustainable, as it would eventually lead to an energy imbalance and a decrease in efficiency over time.

For time, t, in hours, 0 ≤ t ≤1, a bug is crawling at a velocity, v, in m/h given by v=51+t. Use Δt=0.2 to estimate the distance that the bug crawls during this hour.a) Find an overestimate and an underestimate.b) Then average the two to get a new estimate.

Answers

The overestimate and underestimate are 10.36 m and 51 m/h.10.28 m is the new estimate.

a) To estimate the distance that the bug crawls during this hour, we can use the formula:

distance = velocity multiplied by time

Using t = 0.2, we can find an overestimate by using t = 0.8 and an underestimate by using t = 0.

Overestimate: velocity = 51 + 0.8 = 51.8 m/h, distance = 51.8 x 0.2 = 10.36 m.

Underestimate: distance = 51 x 0.2 = 10.2 m velocity = 51 + 0 = 51 m/h

b) To find a new estimate, we can average the overestimate and underestimate: (10.36 + 10.2) / 2 = 10.28 m is the new estimate.

We used the formula distance = velocity x time to estimate how far a bug crawls in an hour. The velocity of the bug is given by the equation v = 51 + t, where t is the time in hours. To calculate the distance, we need to know the value of t.

In this case, we have a time range of 0  t  1, and we have chosen a small time interval of t = 0.2 to estimate the distance. Using this time interval, we can calculate the distance at different points in time within the given range.

Answers

Amanda would need to catch up to Ben in 6/10 hours, or 0.6 hours.

What is distance?

Use the distance equation d = st, which reads distance equals speed times time, to find the distance. Given that both rate and speed denote a specific amount of travel per unit of time, such as miles per hour or kilometers per hour, they are comparable. R = s = d/t indicates that rate r is equal to speed s.

At 7 miles per hour, Amanda starts jogging down the same path.

Thus, following t hours, Amanda's position is determined by:

A(t) = 7t

Ben begins moving at a 2mph pace along a path.

Ben will be at position 2×1.5 = 3 when Amanda departs in an hour and a half. Ben's position therefore after t hours is as follows:

Answers

The statement "Lt= L1 + L2 + L3 is the formula for finding the total inductance of a circuit when there is more than one inductor connected in series" is True.

The formula Lt = L1 + L2 + L3 is the correct formula for finding the total inductance of a circuit when there is more than one inductor connected in series.

When inductors are connected in series, the total inductance of the circuit is the sum of the individual inductances of the inductors. This is because the magnetic field created by each inductor adds together and the effective inductance is the sum of the individual inductances.

This is based on the principle of additivity of inductances in series. The total inductance of a series circuit is equal to the sum of the individual inductances. The current flowing through each inductor is the same and the voltage across each inductor is proportional to its inductance.

It is important to note that this formula is only true for inductors connected in series. When inductors are connected in parallel, the total inductance is given by the formula:

Answers

The runner travels 42.24 meters in the next 4.80 seconds while decelerating at a rate of 2.40 m/s^2.

What is velocity?

Velocity is a vector quantity that describes the rate of change of an object's position in a given direction. It is typically represented as a combination of a magnitude (speed) and a direction.

To determine the distance the runner travels in the next 4.80 s, we can use the equation of motion for constant acceleration:

d = vi*t + (1/2)at^2

where d is the distance traveled, vi is the initial velocity, t is the time interval, and a is the acceleration.

In this case, the initial velocity is 8.80 m/s, the acceleration is -2.40 m/s^2 (since it is deceleration), and the time interval is 4.80 s.

So, we can plug in the known values into the equation:

d = vi*t + (1/2)at^2

d = 8.804.80 + (1/2)(-2.40)*(4.80)^2

A student throws a 140 g snowball at 8.5 m/s at the side of the schoolhouse, where it hits and sticks.

Answers

The magnitude of the average force on the wall is 2026 N to two significant figures.

What is average force?

Average force is the average of all the forces applied over a period of time. It is calculated by dividing the total force by the number of forces applied. For example, if you applied 10 forces over 10 seconds, the average force would be the sum of those 10 forces divided by 10. The average force is a measure of the average net force on an object over a given period of time and can be used to measure the rate of acceleration of an object. Average force can also be used in kinematics to calculate the velocity of an object over time.

The magnitude of the average force on the wall can be calculated using the equation: Force = (mass x velocity) / time, which can be rearranged to calculate Force = (mass x velocity) x time.
In this case, the mass of the snowball is 140 g, the velocity is 8.5 m/s, and the time of the collision is 0.19 s. Plugging these values into the equation gives us an average force of 2026.3 Newtons.

a wheel 31 cm in diameter accelerates uniformly from 235 rpm to 370 rpm how far will a point on the edge of the wheel have traveled in this

Answers

The point on the edge of the wheel will have traveled approximately 1.09 meters.

To find the distance traveled, we first need to find the total angle the wheel has rotated through. We can do this by finding the difference in the final and initial angular velocities (370 rpm - 235 rpm = 135 rpm) and multiplying that by the time it took for the acceleration to occur.

Next, we need to find the distance traveled by the point on the edge of the wheel. We can do this by multiplying the total angle rotated by the radius of the wheel (31 cm). So, (135 rpm * (1 min/60 sec)) * (31 cm) = 1.09 meters.

A tennis ball with a speed of 28 m/s is mov-
ing perpendicular to a wall. After striking
the wall, the ball rebounds in the opposite
direction with a speed of 19.516 m/s.
If the ball is in contact with the wall for
0.0101 s, what is the average acceleration of
the ball while it is in contact with the wall?
Take “toward the wall” to be the positive
direction.

Answers

the  Average acceleration of the ball is 4704.6 m/s² away from the wall.

What is acceleration?

Acceleration is the rate of change of velocity.

To calculate the acceleration of the ball, we use the formula below

Formula:

a = (v-u)/t................. Equation 1

Where:

a = Accelerationv = Final velocityu = Initia; velocityt = Time

From the question,

Given:

v = -19.516 m/s (Rebounds)u = 28 m/st = 0.0101 s

Substitute these values into equation 1

a = (-19.516-28)/0.0101a = 4704.6 m/s² aways from the wall

Hence, the  acceleration of the ball is 4704.6 m/s².

Answers

According to the question, the material density of the cylinder is 25ρ/12.

What does density mean?

The density of a place refers to the quantity of things—which may include humans, creatures, vegetation, or objects—there are in it. Divide the number of items by the area's measurement to determine density. A country's population density is calculated by dividing its total population by its area, expressed in sq.km or miles.

the solution of question is -

ρ(cylinder)= [2ρ×2L/3+3ρ(L/4)] / L

what is the capacitance of a parallel plate capacitor having plates of area 1.50 m2 that are separated by 0.0108 mm?

Answers

The capacitance of a parallel space capacitor having plates of area 1.50 m2 that are separated by 0.0108 mm is 12.2972 F.

On an empty capacitor, there is no dielectric so 8.854 x 10-12

C=EA/(d)

where,

C is capacitance, A is area, d is distance between the parallel plate and E is dielectric constant.

Substituting the values in the formula,

C=(8.854 x 10-12)(1.50 m2)/ (0.0108)

C= 12.2972 X 10-10 F

Capacitance is the ability of a dielectric to hold or store an electric charge.

Dielectric constant is a  factor that indicates the ability of an insulator to concentrate electric flux, also known as relative permittivity.

Dielectric strength is the ability of a dielectric to withstand a potential difference without internal arcing

Dielectric absorption is the ability of a capacitor to discharge completely to zero. This is sometimes called battery action or capacitor memory.

A baseball bat strikes a baseball with a force of 35 n. the bat is in contact with the ball for 0.12 s.
what impulse did the bat exert on the baseball to change the ball's momentum?

Answers

The impulse exerted by the bat on the baseball is 4.2 Ns, to change the ball's momentum.

What is the impulse?

Impulse is the sudden force or energy that causes an object to move in a particular direction. It is the product of a force applied over a certain period of time. Impulse is a vector quantity, meaning it has both magnitude and direction.

Forces such as gravity, friction, and pressure all create impulse. Impulse is also the integral of a force over a given period of time, which is the same as the change in momentum of an object. Impulse is an important concept in physics, as it can be used to describe the motion of objects and to calculate the velocity and acceleration of objects.

Using impulse-momentum theorem

[tex]\Delta p = F\Delta t[/tex]

p = 35 × 0.12

p = 4.2 Ns

Thus, The impulse exerted by the bat on the baseball is 4.2 Ns, to change the ball's momentum.
