Use the principle of superposition (Equation 1.3) to predict the electric field at the point 0.5 meters to the right and 1.5 meters above the 5 nC charge. Express your result both in terms of x and y components, and then in terms of total magnitude and direction.

Answer:

The number of cycles can be calculated by dividing the total time by the period:

Number of cycles = Total time / Period

In this case, the period is 0.044 s and the total time is 22 s, so:

Number of cycles = 22 s / 0.044 s = 500

Therefore, the energy source will make 500 cycles in 22 seconds.

The velocity of the players just after the tackle is 0.91 m/s moving eastward and the decrease in kinetic energy is -1488 J

The law of conservation of linear momentum states that:

Momentum before collision = momentum after collision

Hence:

Where m₁, m₂ are masses of the object, u₁, u₂ are the object initial velocity and v is the velocity of both objects after collision.

a)

The velocity of the players just after the tackle is 0.91 m/s moving eastward.

b)

Initial kinetic energy = (1/2)(91)(5)² + (1/2)(95)(-3)² = 1565 J

Final kinetic energy = (1/2)(91 + 95)(0.91)² = 77 J

The decrease in kinetic energy = 77 - 1565 = -1488 J

If mass of mars = 6.418 x 1023 kg and radius of mars = 3.38 x 106 m, then the acceleration due to gravity on the surface of Mars is approximately 3.71 m/s².

To calculate the acceleration due to gravity on the surface of Mars, you can use the following formula:

g = (G * M) / R²

where g is the acceleration due to gravity, G is the gravitational constant (6.674 x 10^-11 N m²/kg²), M is the mass of Mars (6.418 x 10^23 kg), and R is the radius of Mars (3.38 x 10^6 m).

Plugging in the values, we get:

g = (6.674 x 10^-11 N m²/kg² * 6.418 x 10^23 kg) / (3.38 x 10^6 m)²

g ≈ 3.71 m/s²

If he accelerates upward at a rate of 1.35 m/s²,  the tension in the rope is 83.03 N.

To find the tension in the rope, we need to use Newton's second law of motion which states that force is equal to mass multiplied by acceleration. In this case, the force is the tension in the rope, the mass is the mass of the gymnast, and the acceleration is the upward acceleration of the gymnast.

Tension = mass x acceleration

T = m x a

Substituting the given values, we get:

T = 61.5 kg x 1.35 m/s²

T = 83.03 N

Explanation: When the gymnast climbs the rope, he exerts a force on the rope, and the rope exerts an equal and opposite force on him. This force is the tension in the rope. According to Newton's second law of motion, this force is proportional to the mass of the object and the acceleration it experiences.

In this case, the tension in the rope is directly proportional to the mass of the gymnast and the acceleration at which he climbs. Therefore, we can use the formula T = m x a to find the tension in the rope.

The catch in this one is:  We don't know how much force the student used to push the bike.  

It wasn't necessarily the 100N.  That's just the weight of the bike. But you know that you can push a car, a wagon, or a bicycle hard, you can push it not so hard, you can give it a little push, you can give it a big push, you can push it strong, you can push it weak, you can push it medium.  The harder you push, the more it'll accelerate, but it's completely up to you how hard you want to push.  That's what's so great about wheels !  That's why they were such a great invention ! This is where I made my biggest mistake. This guy came into my store one day and said he's got this great invention, it's definitely going to take off, it'll be a winner for sure, he called it a "wheel".  I looked at it, I turned it over and I looked on all sides. I thought it was too simple.  I didn't know then it was elegant. I threw him out.  I was so dumb.  I could have invested money in that guy, today I would have probably more than a hundred dollars.

Anyway, can we figure out how much force the student used to push with ?  Stay tuned:

-- The bike covered 15 meters in 5 seconds.  Its average speed during the whole push was (15m/5s) = 3 meters/sec.

-- If the bike started out with no speed, and its average speed was 3 m/s, then it must have been moving at 6 m/s at the end of the push.

-- If its speed increased from zero to 6 m/s in 5 seconds, then its acceleration was (6m/s / 5 sec) = 1.2 m/s²

-- The bike's weight is 100N.  

(mass) x (gravity) = 100N

Bikemass = (100N) / (9.8 m/s²)

Bikemass = 10.2 kilograms

-- F = m A

Force = (mass) x (acceleration)

Force = (10.2 kg) x (1.2 m/s²)

Force = 12.24 N

-- Work = (force) x (distance)

Work = (12.24 N) x (15 m)

Work = 183.67 Joules

-- Power = (work done) / (time to do the work)

Power = (183.67 joules) / (5 seconds)

Power = 36.73 watts

The spaceship would have to accelerate by 3250 m/s to make a break for it at apogee. This is a faster increase than at perigee, so it is more effective to flee during perigee.

If you begin at a speed of less than 11 km/h at ground level and don't receive any additional "push," you will fall back to the earth. You cannot slow down once you begin moving at a speed greater than 11 km/h.

The cork leaves the spring at a speed of 3.02 m/s.

We can use the conservation of energy to determine the speed at which the cork leaves the spring.

The initial potential energy stored in the spring is converted to the kinetic energy of the cork as it leaves the spring. Neglecting air resistance, the conservation of energy equation is:

(1/2) k x^2 = (1/2) m v^2

where k is the spring constant, x is the distance the spring is compressed, m is the mass of the cork, and v is the speed of the cork as it leaves the spring.

Substituting the given values:

(1/2) * 18 N/m * (7.47 cm / 100 cm/m)^2 = (1/2) * 0.009 kg * v^2

Solving for v:

v^2 = (18 N/m * (7.47 cm / 100 cm/m)^2) / 0.009 kg

v^2 = 9.119 m^2/s^2

Taking the square root of both sides:

Explanation:

The stock person at the grocery store does positive work on the boxes of tomatoes during segments (1) and (5) of their job.

When the stock person picks up the boxes from the stockroom floor, they lift the boxes against the force of gravity, which requires them to do positive work on the boxes.

Similarly, when the stock person lowers the boxes slowly to the floor, they are lowering the boxes with control and against the force of gravity, which again requires them to do positive work on the boxes.

The other segments of the job, accelerating to a comfortable speed, carrying the boxes at a constant speed, and decelerating to a stop, do not involve doing positive work on the boxes.

Instead, these segments involve the stock person using force to move the boxes without changing their potential energy, which is a measure of the work done on an object due to its position or configuration.

The question is: You have 500g of ethyl alcohol at a temperature of -40 ° C. How much heat is needed to transform it into steam at a temperature of 150ºC?

Answer: 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of \(-40^{o}C\) to \(150^{o}C\).

Explanation:

Given: Mass = 500 g

Initial temperature = \(-40^{o}C\)

Final temperature = \(150^{o}C\)

The standard value of specific heat of ethyl alcohol is \(2.46 J/g ^{o}C\).

Formula used to calculate the heat energy is as follows.

\(q = m \times C \times (T_{2} - T_{1})\)

where,

q = heat energy

m = mass of substance

C = specific heat

\(T_{1}\) = initial temperature

\(T_{2}\) = final temperature

Substitute the values into above formula as follows.

\(q = m \times C \times (T_{2} - T_{1})\\= 500 g \times 2.46 J/g^{o}C \times [150 - (-40)]^{o}C\\= 233700 J\)

Thus, we can conclude that 233700 J heat is needed to transform ethyl alcohol into steam at a temperature of \(-40^{o}C\) to \(150^{o}C\).

To determine the volume of a sample of strontium with a given mass, we can use the formula:

Volume = Mass / Density

Given:

Density of strontium (d) = 2.60 g/cm^3

Mass of the sample = 47.2 pounds

Before we proceed, let's convert the mass from pounds to grams, as the density is given in grams per cubic centimeter (g/cm^3).

1 pound is approximately equal to 453.592 grams.

Mass of the sample in grams = 47.2 pounds * 453.592 grams/pound

Now, we can calculate the volume using the formula:

Volume = Mass / Density

Volume = (47.2 * 453.592) / 2.60

By performing the calculations, we can determine the volume of the strontium sample in cubic centimeters.
