A DC motor is powered with Ea = 400V, the armature resistance is Ra = 20, the torque constant of the motor is K+ = 1 Nm/A.

The load torque intercepts the motor torque in two places, only one will be positive, drop you will again need to solve = 0. d the given details are Ea = 400VRa = 20K+ = 1 Nm/A

To find; Gear ratio G required to drive this load at its maximum operating speed.

Formula used: θ=K+ * Ia The motor torque, Tm = K+ * Ia The load torque, TL = J * dw / G The armature current, Ia = (Ea - V) / Ra By equating the motor torque and load torque, we have; K+ * Ia = TL The load torque is positive, so we have;TL = J * dw / G Since the load is operating at maximum speed, d w = 0So, TL = 0 = J * 0 / G

Thus, G is not found in the equation.

So, we can conclude that G does not affect the maximum speed of the motor. The maximum speed is determined by the back EMF, Ea, and the motor constants, K+ and Ra.

So, the gear ratio G is irrelevant in determining the maximum speed of the motor.

It will take an additional 7.33 minutes for the cake to cool from 200 degrees F to 90 degrees F after the initial 10 minutes of cooling.

To calculate how much longer it will take for the cake to cool to 90 degrees F, we need to first determine the rate at which the cake is cooling. We can do this by calculating the temperature difference between the cake and the room and dividing it by the time it takes for that temperature difference to occur.
In this case, the temperature difference between the cake and the room is 280 degrees F (350-70=280) when the cake is removed from the oven. After 10 minutes, the temperature difference is 130 degrees F (200-70=130). Therefore, the cake is cooling at a rate of 15 degrees F per minute (280-130=150 degrees F in 10 minutes; 150/10=15).
To determine how much longer it will take for the cake to cool to 90 degrees F, we need to calculate the time it takes for the temperature to drop from 200 degrees F to 90 degrees F. This is a temperature difference of 110 degrees F (200-90=110), so it will take approximately 7.33 minutes (110/15=7.33) for the cake to cool from 200 degrees F to 90 degrees F.

It is unlikely that a tortoise that lived to 100 and had 10 surviving offspring had equal fitness as a tortoise that lived to 30 and had 10 surviving offspring considering only this generation.

The concept of fitness in evolutionary biology refers to an organism's ability to survive and produce offspring in its environment. Fitness is measured by an individual's reproductive success relative to others in the same population. In this case, both tortoises had the same number of surviving offspring (10), which suggests that they had the same reproductive success.

Therefore, it is unlikely that they had equal fitness, despite the difference in lifespan. However, it's worth noting that this is a simplified example, and in reality, there are many factors that can affect an organism's fitness, including its ability to survive and reproduce over multiple generations.

Explanation:

By Hooke's law, the force applied to a spring is proportional to the stretch of the spring, so

F = kx

Where F is the force, k is the spring constant and x is how much it is stretched.

So, replacing k by 58N/cm and x by 4 cm, we get

F = (58 N/cm)(4 cm)

F = 232 N

Therefore, the force applied is 232 N

The statement "Since monsoons are storms that usually occur during a specific time of year in certain regions, you could not compare them to thunderstorms" is absolutely false.

Monsoon may be characterized as a seasonal transformation in the direction of the predominant, most potent, currents of a region. It blows from cold to warmer regions of the geographical locations.

Thunderstorms basically originated identically with monsoons more frequently. Monsoon involves sudden and gradual rainfall, extreme wind, and a drop-down in temperature.

The occurrence of monsoon is fixed at different geographical locations, but the occurrence of thunderstorms will not be definite or predominantly known.

The gravitational force exerted by one peach on the other can be calculated using the formula F = G(m1m2)/r²,

where F is the force, G is the gravitational constant (6.67 x 10^-11 Nm²/kg²), m1 and m2 are the masses of the two peaches, and r is the distance between their centers of mass.

(a) When the separation between the peaches is 0.25 m, the force exerted by one peach on the other is:

F = (6.67 x 10⁻¹¹ N×m²/kg²) × (0.16 kg × 0.16 kg) / (0.25 m)² = 1.07 x 10⁻⁹N

(b) When the separation between the peaches is 0.50 m, the force exerted by one peach on the other is:

F = (6.67 x 10^-11 N×m²/kg²) ×(0.16 kg × 0.16 kg) / (0.50 m)²= 2.67 x 10⁻¹⁰ N

Therefore, the gravitational force exerted by one peach on the other decreases as the distance between them increases. This is because the force of gravity is an inverse square law, meaning that the force decreases proportionally to the square of the distance between the objects.

Answer: \(200\Omega\)

Explanation:

Given

The battery used is 6V in magnitude

The current flow is 90 mA

If the resistance of A is \(100\Omega\)

Net resistance of the circuit is

\(R_{net}=\dfrac{V}{I}\\\\\Rightarrow R_{net}=\dfrac{6}{90\times 10^{-3}}\\\\\Rightarrow R_{net}=\dfrac{200}{3}\Omega\)

If A and B are in parallel then their net resistance must be   \(\frac{200}{3}\)

\(\dfrac{1}{\frac{200}{3}}=\dfrac{1}{100}+\dfrac{1}{R_b}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3}{200}-\dfrac{1}{100}\\\\\Rightarrow \dfrac{1}{R_b}=\dfrac{3-2}{200}\\\\\Rightarrow R_b=200\Omega\)

There are 0.0568 moles of water molecules in 12 cubic decimetre of water vapour at STP.

The given quantities are as follows; Volume of water vapour at STP = 12 cubic decimetre, Temperature of water vapour at STP = 273 K, Pressure of water vapour at STP = 1 atm

1. Firstly, we need to convert the given volume to liters.

1 decimetre = 0.1 meters

1 cubic decimetre = 0.1 x 0.1 x 0.1 cubic meters = 0.001 cubic meters

1 cubic meter = 1000 liters

1 cubic decimetre = 0.001 x 1000 liters = 1 liter

Therefore, the volume of water vapour at STP is 12 liters.

2. Next, we use the ideal gas law:

PV = nRT

where P = pressure, V = volume, n = number of moles, R = ideal gas constant, and T = temperature.

We can rearrange this equation to solve for n:

n = PV/RT

We need to convert the pressure to Pascals, volume to cubic meters, and temperature to Kelvin.

1 atm = 101325 Pa

12 liters = 0.012 cubic meters

273 K = 0 °C + 273 = 546 R

Now, we can plug in these values:

n = (101325 Pa)(0.012 m³)/(8.314 J/mol·K)(546 K)

n = 0.0568 mol

Therefore, the number of water molecules are 0.0568 moles.

Explanation:

Given that a stone dropped from the top of a 80m high building strikes the ground at 40 m/s after falling for 4 seconds. The stone's potential energy with respect to the ground is equal to its kinetic energy. (use 9 - 10 m/s)

O at the moment of impact

2 seconds after the stone is released after the stone has fallen 40 m

when the stone is moving at 20 m/s

At the top of the hill, the P.E = mgh

P.E = 10 × 80 × m

P.E = 800m

At the moment of impact, K.E = 1/2mv^2

K.E = 1/2 × 40^2 × m

K.E = 1/2 × 1600 × m

K.E = 800m

Since both P.E and K.E are the same, we can therefore conclude that the stone's potential energy with respect to the ground is equal to its kinetic energy at the moment of impact.

The correct answer is option A.

The acceleration is greatest in magnitude and directed downward when the mass is at its lowest point in its oscillation.

When the mass is at its lowest point, the spring is stretched to its maximum extent. The spring exerts a restoring force on the mass, which is directed upward.

The mass's weight, on the other hand, is directed downward. The net force on the mass is therefore directed downward, and the mass accelerates downward.

The acceleration of the mass is greatest at this point because the net force is greatest. The net force is greatest because the spring is stretched to its maximum extent, and the spring's restoring force is therefore greatest.

The acceleration of the mass decreases as it moves upward, and it is zero when the mass reaches its highest point. The acceleration then increases in magnitude as the mass moves downward, and it is greatest when the mass reaches its lowest point.

When a second convex lens is placed in front of the first convex lens, the focus of the combined system changes. The exact change of focus depends on the properties of the lenses and their relative position.

If the second convex lens has a shorter focal length than the first lens and is placed close to the first lens, the combined system will have a shorter effective focal length. This means that the focal point will move closer to the lenses.

This setting can be used in various optical systems such as telescopes,cameras and microscopes. By combining multiple lenses, the overall optical system can achieve specific magnification, focus or aberration correction.

One particular application where a second convex lens is used in front of the first lens is the correction of nearsightedness or myopia. Myopia occurs when the eye's ability to focus is too strong, causing distant objects to appear blurry. A concave lens is usually used to correct myopia, but in some cases a combination of a concave lens and a convex lens is used. The convex lens located at the front helps to reduce the overall performance of the corrective lens system and provides better focus on distant objects.

It is important to note that the exact design and use of lens systems may vary depending on individual requirements and optical properties. A consultation with an optometrist or optical specialist would provide more specific guidance tailored to personal needs.

The work done by the applied force on the block-floor system is 125.46 J.

The work done by a force on an object is given by the formula: work = force × displacement × cos(theta), where theta is the angle between the force and the displacement.

In this case, the force applied is the horizontal force of magnitude 39.8 N, the displacement is 3.26 m, and the angle between the force and the displacement is 0 degrees (cos(0) = 1, since they are in the same direction).

To calculate the work done by the applied force, we can use the formula: work = force × displacement.

work = 39.8 N × 3.26 m = 129.548 J

However, this value represents the total work done on the block. We need to consider the effect of friction on the work done.

The force of kinetic friction can be calculated using the formula: frictional force = coefficient of kinetic friction × normal force.

The normal force is equal to the weight of the block, which is given by: weight = mass × gravity.

normal force = 4.42 kg × 9.8 m/s² = 43.396 N

frictional force = 0.645 × 43.396 N = 27.99482 N

The work done against friction can be calculated using the formula: work against friction = frictional force × displacement.

work against friction = 27.99482 N × 3.26 m = 91.146292 J

Finally, we can calculate the net work done on the block-floor system by subtracting the work done against friction from the total work done:

net work = total work - work against friction = 129.548 J - 91.146292 J = 38.401708 J

Therefore, the work done by the applied force on the block-floor system when the block slides through a displacement of 3.26 m across the floor is 38.401708 J, or approximately 38.40 J.

The work done by the applied force on the block-floor system can be calculated by considering the total work done and subtracting the work done against friction. In this case, the work done is 129.548 J, and the work done against friction is 91.146292 J, resulting in a net work of 38.401708 J.

The average acceleration of the car is 0.2 m/s^2.

To calculate the average acceleration of the car, we need to use the formula:
average acceleration = (final velocity - initial velocity) / distance

In this case, the final velocity is 80 m/s and the initial velocity is 40 m/s. The distance covered by the car is 200 m. So, we can plug in these values to get:
average acceleration = (80 m/s - 40 m/s) / 200 m

Simplifying this expression, we get:
average acceleration = 40 m/s / 200 m
average acceleration = 0.2 m/s^2

Therefore, the average acceleration of the car is 0.2 m/s^2. This means that for every second the car was travelling, it was increasing its speed by 0.2 m/s. Acceleration is a measure of how quickly an object's velocity changes. It is defined as the rate of change of velocity with respect to time. In this case, the car's velocity changed from 40 m/s to 80 m/s over a distance of 200 m. By using the formula for average acceleration, we were able to calculate that the car's acceleration was 0.2 m/s^2. This value tells us how much the car's velocity was increasing every second it was travelling.

After 1 day has passed, approximately 6.25% of Element Z would be remaining.

The half-life of an element is the time it takes for half of the initial amount of the element to decay or transform into another element or isotopes. In this case, Element Z has a half-life of 5 hours.

To determine the percentage of Element Z remaining after 1 day (24 hours), we need to calculate the number of half-lives that have occurred.

Since the half-life of Element Z is 5 hours, there are 24 hours divided by 5 hours, which equals 4.8 half-lives.

Each half-life reduces the amount of Element Z by half. So, after 4.8 half-lives, the remaining amount of Element Z would be (1/2)^(4.8) = approximately 0.0625 or 6.25%.

Therefore, after 1 day has passed, approximately 6.25% of Element Z would be remaining.
