The Energizer 522 V battery can operate such a relay for approximately 0.69 h.

The power consumption of the relay's coil is 6.75 W. The Energizer 522 V battery has a capacity of 522 mA. To calculate how long the battery can operate the relay, we need to know the current draw of the relay in mA.

Since the current draw of the relay is 750 mA, we can use the following formula:

Time (h) = Battery Capacity (mA) / Current Draw (mA)

Time (h) = 522 mA / 750 mA

Time (h) = 0.69 h

Therefore, the Energizer 522 V battery can operate such a relay for approximately 0.69 h.

if the eyeglasses are held at a distance of 1.50 cm from the eyes, a contact lens with a power of -6.00 diopters would be required to correct the man's distant vision.

In the previous problem, we calculated the power of the contact lens that would be required to correct the vision of a very myopic man with a far point of 20.0 cm when the eyeglasses were held at a distance of 0.50 cm from the eyes. We used the lens power equation, which states that the power of a lens (P) is equal to 1 divided by the focal length (f) of the lens in meters.

In this case, the man's far point was 20.0 cm, so we could assume that his eye's focal length was -20.0 cm (since the focal length of a lens is negative for a myopic eye). Therefore, to correct his vision, we needed to find the power of the contact lens required to produce a virtual image at a distance of 20.0 cm behind the eye.

Using the lens power equation, we found that the power of the contact lens required to correct his vision was -5.00 diopters. However, in this problem, we are asked to calculate the power of the contact lens required to correct his vision when the eyeglasses are held at a distance of 1.50 cm from the eyes.

To solve this problem, we can use the thin lens equation, which relates the object distance (o), the image distance (i), and the focal length (f) of a lens. The thin lens equation is:

1/f = 1/o + 1/i

Since the object (in this case, the virtual image produced by the contact lens) is at the man's far point of 20.0 cm, we can set o = -20.0 cm. We want the virtual image to be produced at a distance of 1.50 cm behind the eye, so we can set i = -1.50 cm. Solving for f gives:

1/f = 1/-20.0 + 1/-1.50

1/f = -0.08

f = -12.5 cm

Therefore, the power of the contact lens required to correct the man's vision when the eyeglasses are held at a distance of 1.50 cm from the eyes is:

P = 1/f = 1/-0.125 = -8.00 diopters

However, since the contact lens is on the eye (not in front of it, as with the eyeglasses), we need to subtract the power of the eyeglasses (assuming they have the same prescription) to get the net power of the corrective system. If we assume the eyeglasses have a power of -2.00 diopters, then the power of the contact lens required to correct the man's vision would be:

P = -8.00 - (-2.00) = -6.00 diopters

Therefore, if the eyeglasses are held at a distance of 1.50 cm from the eyes, a contact lens with a power of -6.00 diopters would be required to correct the man's distant vision.

Answer:

2 to 4 hours

Explanation:

Given that,

Microbial food infections

We know that,

Food infection :

When we eat old food, uncooked, fermented food, more junk food and contaminated food then 2 to 4 hours after eating we started vomiting, headache then we affected by food infections.

So, we can say that microbial food infections are usually not seen until 2 to 4 hours after eating contaminated food.

To solve this problem, we can use the equations of motion and Newton's second law of motion. The equation of motion for an object moving at constant speed is:

x = x0 + v0t + (1/2)at^2

where x is the final position, x0 is the initial position, v0 is the initial velocity, t is the time, and a is the acceleration.

In this case, the initial position is 0 m (since the crate starts at the beginning of the 12 m distance), the initial velocity is 0 m/s (since the crate starts at rest), and the time is 12 s (since the crate moves at a constant speed of 1.50 m/s).

We can use these values to solve for the acceleration:

12 m = (1/2)(a)(12 s)^2

a = 0.5 m/s^2

Now that we know the acceleration, we can use Newton's second law of motion to find the normal force:

F = ma

N = (20 kg)(0.5 m/s^2)

N = 10 N

This is the magnitude of the normal force on the crate. Note that this is the normal force exerted by the floor on the crate, not the force of tension in the rope. To find the force of tension in the rope, we would need to consider the angle of the rope and the direction of the force.

Answer:

Explanation:

Using the conservation of law of momentum which states that the sum of momentum of bodies before collision is equal to the sum of the bodies after collision.

Momentum = Mass (M) * Velocity(V)

BEFORE COLLISION

Momentum of 0.25kg body moving at 1.0m/s = 0.25*1 = 0.25kgm/s

Momentum of 0.15kg body moving at 0.0m/s(body at rest) = 0kgm/s

AFTER COLLISION

Momentum of 0.25kg body moving at x m/s = 0.25* x= 0.25x kgm/s

x is the final velocity of the 0.25kg ball

Momentum of 0.15kg body moving at 0.75m/s(body at rest) =

0.15 * 0.75kgm/s = 0.1125 kgm/s

Using the law of conservation of momentum;

0.25+0 = 0.25x + 0.1125

0.25x = 0.25-0.1125

0.25x = 0.1375

x = 0.1375/0.25

x = 0.55m/s

Since the 0.15 kg ball moves off to the right after collision, the 0.25 kg ball will move at 0.55 m/s towards the right

A solenoid has a ferromagnetic core, n = 1000 turns per meter, and i = 5.0 a. if b inside the solenoid is 2.0 t, permeability of the core material is 1.59 × 10³ H/m.

We can use Ampere's law to find the magnetic field inside the solenoid:

B = μ₀ n i

where B is the magnetic field, μ₀ is the permeability of free space, n is the number of turns per unit length, and i is the current.

Substituting the given values, we get:

B = μ₀ n i = (4π × 10⁻⁷ T·m/A) × 1000 turns/m × 5.0 A = 0.002 T

Therefore, the magnetic field inside the solenoid is 0.002 T.

We also know that the magnetic field inside a ferromagnetic material is related to the magnetic field in free space by the permeability of the material:

B = μ B₀

where B is the magnetic field in the material, μ is the permeability of the material, and B₀ is the magnetic field in free space.

Substituting the given values, we get:

μ = B / B₀ = 0.002 T / 4π × 10⁻⁷ T·m/A = 1.59 × 10³ H/m

Therefore, the permeability of the core material is 1.59 × 10³ H/m.

Explanation:

I got it wrong with the answer A.

it is harder to swim in water with a current (like the ocean) than in contained water (like a pool) because Still water is an immovable object, but currents have their own momentum. The correct option is D.

Newton's first law of motion, also known as the law of inertia, states that "an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity unless acted upon by an unbalanced force."

This means that an object will continue to move in a straight line at a constant speed unless an unbalanced force acts upon it. In addition, if an object is at rest, it will remain at rest unless acted upon by an unbalanced force.

The law of inertia can be applied to many situations. For example, if a book is sitting on a table, it will remain at rest until a force is applied to it. Similarly, if a ball is rolling on a flat surface, it will continue to roll at a constant speed in a straight line unless a force, such as friction, slows it down or changes its direction.

This law is fundamental to understanding the behavior of objects in motion, and it forms the basis for the other two laws of motion formulated by Sir Isaac Newton.

Here in the Question,

Swimming in a pool versus swimming in the ocean, the difference lies in the presence of a current in the ocean.

The current in the ocean has its own momentum, and when a swimmer enters the water, they are faced with an additional force that they must overcome to move forward. This means that the swimmer must apply more force and use more energy to overcome the force of the current and move forward in the water.

In still water, on the other hand, there is no external force acting on the swimmer, so they only have to overcome the resistance of the water itself to move forward.

Therefore, The correct answer is D i.e Still water is an immovable object, but currents have their own momentum.

I = I₁ = I₂ = I₃ = .....

V = V₁ + V₂ + V₃ + ...

A series circuit has

Find the voltage drop across the 10-ohm resistor!

In series, the applied voltage is the sum of each voltage. It means that the voltage depends on its resistance and current.

We count the total resistance.

R = R₁ + R₂

R = 10 + 20

R = 30 Ω

The current flow in the circuit can be determined using the equation in Ohm's law.

I = V/R

I = 30/30

I = 1 A

The current on each resistance is the same. So

I₁ = I₂ = I = 1 A

The voltage drop across the 10-ohm resistor is

V₁ = I₁R₁

V₁ = 1(10)

V₁ = 10 volts

Hence, across the 10-ohm resistor, the voltage is 10 volts.
