Answer:

Not all of the time, it can also depend on the strength of the magnet.

Explanation:

say you have a small very strong magnet, that might work just as well as a large but week magnet.

To find the coefficient of friction with mass and force, you can use the equation: \(\[ \text{{Coefficient of Friction}} = \frac{{\text{{Force}}}}{{\text{{Normal force}}}} \]\).

The coefficient of friction is a measure of the resistance between two surfaces when they are in contact and sliding against each other. It quantifies the amount of frictional force between the surfaces. The force here refers to the force applied parallel to the surface, which causes the object to move or resist motion. The normal force is the perpendicular force exerted by a surface to support the weight of an object. To calculate the coefficient of friction, you divide the force applied by the normal force.

For example, let's say you have a mass of 10 kg and a force of 50 N acting on it. If the object is on a horizontal surface with no vertical acceleration, the normal force would be equal to the weight of the object, which is \(\( \text{{mass}} \times \text{{gravitational acceleration}} \)\). If the gravitational acceleration is \(9.8 m/s\(^2\)\), then the normal force would be \(\( 10 \, \text{kg} \times 9.8 \, \text{m/s}^2 = 98 \, \text{N} \)\). Plugging these values into the formula, the coefficient of friction would be \(\( \frac{50 \, \text{N}}{98 \, \text{N}} = 0.51 \)\).

Direct wave Propagation :-When radio waves travel from the transmitter antenna toward the receiver antenna in a straight line, both antennas are within each other's horizon view.

Ocean waves, electromagnetic waves, and stadium crowd waves are most often referred to as transverse waves. Transverse waves are so-named because the waves' periodic disturbances are at right angles to the direction of propagation. In these waves, the oscillation of the particles or fields is perpendicular to the direction of wave propagation, creating a distinct "up and down" motion along the path of the wave.

The term that increases when air faces greater resistance against an object with a larger surface area is drag.

The drag force is created when a solid object moves through a fluid (liquid or gas), such as air, and experiences resistance to its motion.Drag can be affected by various factors, including the object's shape and surface area. In general, objects with larger surface areas will experience more drag than those with smaller surface areas because they create more friction with the surrounding fluid. For example, a flat, wide object like a barn door will experience more drag than a narrow object like a pencil because it has a larger surface area. Similarly, a parachute will experience a large amount of drag because of its large surface area, which creates a significant amount of friction with the air molecules around it.In order to minimize drag and increase efficiency, engineers and designers often try to create streamlined objects with minimal surface area. This can be seen in the design of cars, airplanes, and even swimsuits used by competitive swimmers. By minimizing drag, these objects are able to move more quickly and with less effort through their respective fluids.

The unit tangent vector T(t) for the curve defined by r(t) = (e², 2t, e) at t = 2 is \(\[T(2) = \left(\frac{e^2}{\sqrt{e^4 + 16 + e^2}}, 4, e\right)\]\). The unit normal vector N(t) for the curve at \(\[N(2) = \left(\frac{-2e^2}{\sqrt{4e^4 + 1}}, 1, 0\right)\]\).

The normal acceleration ar at \(\[ar(2) = \frac{\sqrt{4e^4 + 1}}{\sqrt{e^4 + 16 + e^2}}\]\). The tangential acceleration at t = 2 is aT(2) = 0 since the curve is defined as a straight line and has no curvature.

To find the unit tangent vector T(t), we take the derivative of the position vector r(t) with respect to t and normalize it by dividing by its magnitude. The derivative of \(\[T(t) = \frac{(e^2, 4, e)}{\sqrt{e^4 + 16 + e^2}}\]\).

To find the unit normal vector N(t), we differentiate T(t) with respect to t and normalize the resulting vector. The derivative of T(t) is (0, 0, 0), which means the curve is a straight line. Therefore, N(t) is constant and given by \(\[N(t) = \frac{(-2e^2, 1, 0)}{\sqrt{4e^4 + 1}}\]\).

The normal acceleration ar at t = 2 is the magnitude of the derivative of T(t) with respect to t, which simplifies to \(\[\frac{\sqrt{4e^4 + 1}}{\sqrt{e^4 + 16 + e^2}}\]\).

Since the curve is a straight line, there is no change in the direction of the velocity vector, and therefore, the tangential acceleration aT is zero.

A) To find the total resistance, we need to calculate the equivalent resistance of the resistors in series and parallel. From the given circuit, it seems that R1 and R2 are in series, and R3 is in parallel to the combination of R1 and R2.

The resistance of R1 and R2 in series can be added:

R1 + R2 = 5 Ω + 10 Ω = 15 Ω

The total resistance of R1 and R2 in series is 15 Ω.

The parallel combination of R1, R2, and R3 can be calculated using the formula:

1 / (R1 + R2) = 1 / 15 Ω

Adding R3 in parallel to this combination:

1 / (R1 + R2) + 1 / R3 = 1 / 15 Ω + 1 / 15 Ω = 2 / 15 Ω

Taking the reciprocal of the sum gives the total resistance:

1 / (2 / 15 Ω) = 15 Ω / 2

The total resistance is 7.5 Ω.

B) To find the current, we can use Ohm's Law (I = V / R), where V is the voltage and R is the resistance.

In this case, the voltage across the circuit is given as 1.5 V. Using the total resistance of 7.5 Ω:

I = 1.5 V / 7.5 Ω = 0.2 A or 200 mA

The current flowing through the circuit is 0.2 A or 200 mA.

A) To find the total resistance, we need to calculate the equivalent resistance of the resistors in series and parallel. From the given circuit, it seems that R1, R2, and R3 are in series.

The total resistance is the sum of R1, R2, and R3:

R_total = R1 + R2 + R3 = 50 Ω + 100 Ω + 150 Ω = 300 Ω

The total resistance is 300 Ω.

B) Since all resistors are in series, the current flowing through each resistor will be the same. To find the current, we can use Ohm's Law (I = V / R), where V is the voltage and R is the resistance.

The voltage across the circuit is given as 25 V. Using the total resistance of 300 Ω:

I = 25 V / 300 Ω = 0.0833 A or 83.3 mA (rounded to 3 decimal places)

The current flowing through each resistor is approximately 0.0833 A or 83.3 mA.

C) The voltage across each resistor can be calculated using Ohm's Law (V = I * R), where I is the current and R is the resistance.

Voltage across R1: V1 = I * R1 = 0.0833 A * 50 Ω = 4.165 V

Voltage across R2: V2 = I * R2 = 0.0833 A * 100 Ω = 8.33 V

Voltage across R3: V3 = I * R3 = 0.0833 A * 150 Ω = 12.495 V

The voltage across R1 is approximately 4.165 V, across R2 is approximately 8.33 V, and across R3 is approximately 12.495 V.

When discussing Newton's laws of motion, people most likely use the terms "action" and "reaction" when talking about Newton's third law of motion.

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object.

In other words, if object A pushes or pulls on object B with a certain force, then object B will push or pull back on object A with an equal and opposite force. This law applies to all types of forces, whether they are contact forces or non-contact forces, such as gravitational or electromagnetic forces.

This law is important in understanding how forces work in the physical world. It helps explain why things don't just keep accelerating indefinitely when a force is applied, and why forces always come in pairs. It also plays a crucial role in understanding the behavior of systems like rockets, airplanes, and cars.

Answer:

The brick wall has less mass compared to the soccer ball. With the ball you would have to use less force to make it go a certain distance. You would have to apply more force in the case of the brick wall to get it to go the same distance as the soccer ball.

Heavier things need more force and acceleration to move the same distance as lighter things because they have more mass.

Force by wall.

Take mass of wall as 120 kg and acceleration as 10m/s^2, Then the total force acting would be F = ma

120 * 10 = 1200 N

According to Newton's 3rd law of motion, Every action has an equal and opposite reaction. So, the force you apply on the wall is equivalent to the force the wall applies on you. Hence the wall applies a force of 1200 N on you which is why you get hurt.

Force by soccer ball.

The mass of a soccer ball is obviously lesser than the mass of a wall. Take mass of soccer ball as 0.5 kg and take the same acceleration as 10m/s.

F = ma, Hence

Force = 0.5 * 10 = 5 N

The force applied on the ball is much less compared to the force applied on the soccer wall that is just 5 N. Using the 3rd law of motion, we can prove that only a force of 5 N acts on us when we kick a ball. Hence it does not hurt.

Thus, proved.

Hydrogen has partial positive charge and oxygen has partial negative charge.

The link between water is known to be H-O-H. The octet rule states that oxygen must be surrounded by 8 electrons. Four is provided by the two bonds with H. The remaining 4 therefore happen as non-bonding electrons. Since oxygen is more electronegative than hydrogen, it receives a partial negative charge as indicated in image as follows. Covalent bond is present between oxygen and hydrogen atom.
