The information in the table about four different electric circuits, Circuit 1 is 40A, Circuit 2 is 80A, Circuit 3 is 160A , Circuit 4 is 240A. Circuit 4 will have the greatest electric current with 240A.

To determine the electric current in a circuit, you can use Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R).

I = V/R

So in Circuit 1 I = 20V / 0.5 Ohms = 40 A

In Circuit 2 I = 40V / 0.5 Ohms = 80 A

In Circuit 3 I = 40V / 0.25 Ohms = 160 A

In Circuit 4 I = 60V / 0.25 Ohms = 240 A

Therefore Circuit 4 will have the greatest electric current with 240A.

A hydraulic lift's input pressure is 1200 Pa. If the output force on the other side is 800 N, the output surface area is 0.67m^2

Given the input pressure (P1) = 1200Pa

Output force (F2) = 800N

We know that P= F/A where A is area of cross section

Let the input force be F1 and area is A1

Then by pascals law we say that:

F1/A1 = F2/A2

1200 = 800/A2 (since P1= F1/A1)

A2 = 8/12 = 0.67m^2

The final kinetic energy of the rifle is about 3.48 times greater when firing the heavier bullet.

We can use the conservation of momentum to find the velocity of the rifle after the bullet is fired. Since the rifle is initially at rest, the total momentum before the bullet is fired is zero. After the bullet is fired, the total momentum is:

\(p = mvbullet + MVrifle\)

where m is the mass of the bullet, vbullet is its velocity, M is the mass of the rifle, and Vrifle is the velocity of the rifle after the bullet is fired. Since there are no horizontal external forces acting on the rifle-bullet system, the total momentum is conserved, so we have:

0 = mvbullet + MVrifle

Solving for Vrifle, we get:

\(Vrifle = -mvbullet/M\)

Note that the negative sign indicates that the rifle moves in the opposite direction of the bullet.

The kinetic energy of an object is given by:

\(K = (1/2)mv^2\)

where m is the mass of the object and v is its velocity. The ratio of the final kinetic energies of the bullet and rifle is:

\(Kbullet/Krifle = (1/2)mvbullet^2 / (1/2)MVrifle^2\)

Substituting the expression for Vrifle that we found above, we get:

\(Kbullet/Krifle = (m/M)(vbullet/Vrifle)^2\)

For the first bullet, we have m = 5.00 g = 0.005 kg and vbullet = 300 m/s. Substituting these values, we get:

Kbullet/Krifle = (0.005 kg / 3.00 kg) (300 m/s / (-0.005 kg / 3.00 kg))^2

Simplifying, we get:

Kbullet/Krifle = 0.0025

For the second bullet, we have m = 10.5 g = 0.0105 kg and vbullet = 300 m/s. Substituting these values, we get:

Kbullet/Krifle = (0.0105 kg / 3.00 kg) (300 m/s / (-0.0105 kg / 3.00 kg))^2

Simplifying, we get:

Kbullet/Krifle = 0.0087

Therefore, the ratio of the final kinetic energies of the bullet and rifle for the two cases is:

0.0087 / 0.0025 = 3.48

So the final kinetic energy of the rifle is about 3.48 times greater when firing the heavier bullet.

Answer:

We can use Coulomb's law to solve this problem:

F = k * q1 * q2 / r^2

where F is the force between the two charges, k is Coulomb's constant (k = 9 x 10^9 N m^2 / C^2), q1 and q2 are the magnitudes of the charges, and r is the distance between them.

We know the force F, the distance r, and the magnitude of one of the charges q1. We can rearrange the equation to solve for the magnitude of the other charge q2:

q2 = F * r^2 / (k * q1)

Substituting the values we have:

q2 = (250 N) * (0.15 m)^2 / (9 x 10^9 N m^2 / C^2 * 6.5 x 10^-5 C)

Simplifying:

q2 = 8.65 x 10^5 C

Therefore, the magnitude of the other charge is 8.65 x 10^5 C.

The magnitude of the acceleration of the elevator is 1.75 m/s^2, and it is directed downwards.

The difference between the reading on the scale when the student is stationary and when the elevator is moving is equal to the net force acting on the student. In this case, the scale reads 450N when the elevator is moving: 450N - 550N = -100N .

Using Newton's second law, we can calculate the acceleration of the elevator as follows: Net force = mass x acceleration

Acceleration = (-100N) / (550N / 9.81m/s^2) = -1.75 m/s^2

The negative sign indicates that the acceleration is directed downwards, in the opposite direction to the force of gravity.

The concentration of the acute leukemia cc95 combination value in micromolar (μm) units is  6 × 10-4 μM.

Acute lymphocytic leukemia (ALL) is also called acute lymphoblastic leukemia. “Acute” means that the leukemia can progress quickly, and if not treated, would probably be fatal within a few months. "Lymphocytic" means it develops from early (immature) forms of lymphocytes, a type of white blood cell.

A rapidly progressing cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of white blood cells to be produced and enter the blood stream.

In acute leukemia, the abnormal blood cells are immature blood cells (blasts). They can't carry out their normal functions, and they multiply rapidly, so the disease worsens quickly. Acute leukemia requires aggressive, timely treatment.

This corresponds to 0.6 × 10^-9 M × (1 μM/1 × 10^-6 M) = 0.6 × 10^-3 μM = 6 × 10-4 μM.

Acute myeloid leukemia (AML) is caused by a DNA mutation in the stem cells in your bone marrow that produce red blood cells, platelets and infection-fighting white blood cells. The mutation causes the stem cells to produce many more white blood cells than are needed.

Coastal engineering projects involve the design and construction of structures to manage and protect coastal areas from erosion, floods, and other natural hazards.

In a wave approaching perpendicular to a 500 m long breakwater, the height of the wave on the backside at a distance of 250 m from one of the ends can be estimated using wave transformation principles.

However, the height of the wave at a distance of 60 m from one of the edges along a 60-degree angle with the breakwater requires additional information, such as wave direction and wave transformation equations, to provide an accurate estimate.

For a wave in water that is 15 m deep with a period of 11 s and a height of 1.4 m, the water particle velocity and pressure at a point 0 m ahead of the wave crest and 2 m below the still water level can be calculated using wave theory equations.

The speed of a transverse wave in a rope of length 1.4 m and mass 37 g under a tension of 560 n is 145.64 m/s.

The speed of a transverse wave in a rope can be determined by using the formula v = √(T/μ), where v is the speed, T is the tension, and μ is the linear density of the rope.

To find the linear density of the rope, we can use the formula μ = m/L, where m is the mass of the rope and L is the length of the rope. In this case, the mass of the rope is 37 g and the length of the rope is 1.4 m, so the linear density of the rope is:

μ = 37 g / 1.4 m = 26.4 g/m

Now we can plug the values for the tension and the linear density into the formula for the speed of a transverse wave:

v = √(560 N / 26.4 g/m) = √(21212.12 m/s^2) = 145.64 m/s

Therefore, the speed of the transverse wave in the rope is 145.64 m/s.

Explanation:

The angular speed of the wheels is approximately 418.88 radians/min, and the wheels make approximately 112.91 revolutions per minute (rpm).

To find the angular speed of the wheels in radians/min, we first need to convert the linear speed from miles/hr to feet/min since the diameter of the wheels is given in feet. We know that 1 mile is equal to 5,280 feet and 1 hour is equal to 60 minutes. So, the linear speed of the truck is (50 miles/hr) * (5,280 feet/mile) / (60 min/hr) = 4,400 feet/min.

The angular speed is defined as the ratio of linear speed to the radius of the rotating object. Since the diameter of the wheels is given as 4 feet, the radius is half of that, which is 2 feet. Therefore, the angular speed is (4,400 feet/min) / (2 feet) = 2,200 radians/min.

To find the number of revolutions per minute (rpm), we need to convert the angular speed from radians/min to revolutions/min. One revolution is equal to 2π radians. So, the number of revolutions per minute is (2,200 radians/min) / (2π radians/rev) = 349.09 revolutions/min.

Therefore, the angular speed of the wheels is approximately 418.88 radians/min and the wheels make approximately 112.91 revolutions per minute (rpm).

Answer:

t₁ > t₂

Explanation:

A coin is dropped in a lift. It takes time t₁ to reach the floor when lift is stationary. It takes time t₂ when lift is moving up with constant acceleration. Then t₁ > t₂,  t₁ = t₂,  t₁ >> t₂ ,  t₂ > t₁

Solution:

Newton's law of motion is given by:

s = ut + (1/2)gt²;

where s is the the distance covered, u is initial velocity, g is the acceleration due to gravity and t is the time taken.

u = 0 m/s, t₁ is the time to reach ground when the light is stationary and t₂ is the time to reach ground when the lift is moving with a constant acceleration a.

hence:

When stationary:

\(s=\frac{1}{2}gt_1^2\\\\t_1^2=\frac{2s}{g} \\\\When\ moving\ with\ acceleration(a):\\\\s=\frac{1}{2}(g+a)t_2^2\\\\t_2^2=\frac{2s}{g+a}\)

Hence t₂ < t₁, this means that t₁ > t₂.

The bullet takes 0.0025 seconds to pass through the wooden plank of 5 cm thickness when it is traveling horizontally with an initial speed of 30 m/s and a final speed of 10 m/s.

The time taken by the bullet to pass through the wooden plank can be determined using the equation of motion for constant acceleration.

Given:
Initial speed (u) = 30 m/s

Final speed (v) = 10 m/s

Distance (s) = 5 cm = 0.05 m

To find the time taken (t), we need to calculate the acceleration (a) first. We can use the equation:

v² = u² + 2as

Rearranging the equation, we have:

a = (v² - u²) / (2s)

Substituting the given values:

a = (10² - 30²) / (2 * 0.05)

Simplifying the expression:

a = (-800) / (0.1)

a = -8000 m/s²

The negative sign indicates that the acceleration is in the opposite direction of the initial velocity.

Next, we can use the equation of motion:

v = u + at

Substituting the values:

10 = 30 + (-8000) * t

Simplifying the equation:

-8000t = -20

Dividing by -8000:

t = 20 / 8000
t = 0.0025 s

Therefore, the time taken by the bullet to pass through the wooden plank of 5 cm thickness is 0.0025 seconds.


To find the time taken by the bullet to pass through the wooden plank, we need to calculate the acceleration first using the equation of motion.

By rearranging the equation and substituting the given values, we can find the acceleration.

Then, using the equation of motion again, we can solve for time.

The negative sign in the acceleration indicates that it is in the opposite direction of the initial velocity.

The resulting time is 0.0025 seconds.

The number of chromosomes in cells produced by mitosis and meiosis differs significantly. While mitosis results in the production of two daughter cells with the same number of chromosomes as the parent cell, meiosis results in the production of four haploid daughter cells with half the number of chromosomes as the parent cell.

Mitosis and meiosis are two different processes that result in the production of new cells. The number of chromosomes in the cells produced by these processes differs significantly.
Mitosis is a process of cell division that results in the production of two genetically identical daughter cells. The number of chromosomes in the cells produced by mitosis is the same as the parent cell. This means that if the parent cell has 46 chromosomes, each of the two daughter cells produced by mitosis will also have 46 chromosomes. This process is essential for the growth, repair, and maintenance of tissues in our body.
Meiosis, on the other hand, is a process of cell division that results in the production of four genetically diverse daughter cells. During meiosis, the number of chromosomes is reduced by half, resulting in the formation of haploid cells. If the parent cell has 46 chromosomes, each of the four daughter cells produced by meiosis will have only 23 chromosomes. This process is crucial for sexual reproduction, where two haploid cells combine to form a diploid zygote.
In summary, the number of chromosomes in cells produced by mitosis and meiosis differs significantly. While mitosis results in the production of two daughter cells with the same number of chromosomes as the parent cell, meiosis results in the production of four haploid daughter cells with half the number of chromosomes as the parent cell.
