When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges. Like charges repel, and unlike charges attract. Since a free hanging magnet will always face north, magnets have long been used for finding direction.

Given parameters:

Mass of object = 6.7kg

Velocity  = 8m/s

Unknown parameter:

Kinetic energy  = ?

Energy is defined as the ability to do work. There are two forms of energy;

Kinetic and potential energy.

Kinetic energy is the energy due to the motion of a body. Whereas, potential energy is the energy due to the position of a body usually at rest.

Kinetic energy is mathematically expressed as;

             Kinetic energy  = \(\frac{1}{2} m v^{2}\)

where m is the mass of the body

           v is the velocity of the body

Since we have been given both mass and velocity, input the parameter to solve for the unknown;

            Kinetic energy  = \(\frac{1}{2}\) x 6.7 x 8²   = 214.4‬J

So the kinetic energy of the body is  214.4‬J

Answer:

K = 5706.6 J

Explanation:

Given that,

The mass of a bullet, m = 50 g = 0.05 kg

The velocity of the bullet, v = 720 km/hr = 477.77 m/s

We need to find the kinetic energy of the bullet​. The kinetic energy of an object is due to its motion. It can be given by the formula as follows :

\(K=\dfrac{1}{2}mv^2\\\\=\dfrac{1}{2}\times 0.05\times 477.77 ^2\\\\K=5706.6\ J\)

So, the required kinetic energy of the bullet is equal to 5706.6 J.

Answer:

Potential energy is the stored energy of position possessed by an object. In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.

Answer:

W = 19.845 J

Explanation:

Work is defined as W = Fdcos\(\theta\), where F is the force exerted and d is the distance. Because the direction the ball is falling is the same direction as the force itself, \(\theta\) = 0 deg, and since cos(0) = 1, this equation is equivalent to W = Fd. In this case, the force exerted is the weight force, which is equivalent to m * g. Substituting you get:

W = mgd = 0.810 kg * 9.8 m/s^2 * 2.5m

W = 19.845 J

Find the change in velocity by finding the area under the line in an acceleration v. time graph:

We can divide the area underneath the interval 1 - 2 seconds into a rectangle and a triangle. Use the formulas:

A = l × w

A = 1/2(b · h)

We can solve for the rectangle first:

A = 2 × 1 = 2

Do the remaining area using the formula for a triangle:

A = 1/2 (2 · 2) = 2

Add the areas together:

2 + 2 = 4 m/s.

The Δv (change in velocity) is 4 m/s.

Answer:

Relative humidity depends on the amount moisture actually in the air at some temperature to the amount of moisture that the air can hold.

For instance, at 25 deg C the air has a saturation pressure of 23.76 mm of Hg.

That means that if at that temperature the pressure of the water vapor in the air reaches 23.76 mm Hg then the air is 100% saturated.

I believe the standard air pressure at 25 deg C is 760 mm Hg.

Now if the pressure of the water vapor in the air is 1/2 * 23.76 = 11.88 mm then the air is 50% saturated and the relative hunidity is 50 %.

At 100% relative humidity rain occurs (the air can't hold any more water).

When humidity is high, the chance of precipitation is high. The correct answer is b. When humidity is high, the chance of precipitation is high.

The amount of moisture or water vapor in the air is referred to as humidity. Relative humidity is a common way to measure it since it shows how much moisture the air is holding relative to how much it could contain at a particular temperature.

Any type of water that falls from the atmosphere and makes it to the surface of the Earth is referred to as precipitation. Examples include rain, snow, sleet, and hail.

When humidity levels are high, there is a lot of moisture in the air, which increases the possibility that saturation will occur. Excess water vapor condenses into visible water droplets or ice crystals as the air gets saturated, creating clouds. Condensed moisture in the clouds eventually gains enough weight to return to Earth as precipitation.

Therefore, when humidity is high, the chance of precipitation is high. The correct answer is:

b. When humidity is high, the chance of precipitation is high.

The final answer are current is directly proportional to the potential difference and inversely proportional to the wire's resistance. Therefore, decreasing the resistance of the wire increases the current in the wire.

To increase the current in the wire of an electric current and field investigating setup, the action to be taken is to decrease the resistance of the wire. What is an electric current? The flow of electrons in a conductor is known as an electric current. To complete an electric circuit, the electrons must flow continuously in a circular pattern.

The electron movement is generated by a power supply, such as a battery. Electrons are pushed out of one end of the battery by a voltage differential between the battery terminals (the potential difference). Electrons enter the other end of the battery and complete the circuit.

The potential difference between the battery terminals drives the electrons around the circuit. This generates an electric current. The formula for current is: I = Q/t Where I is the current, Q is the amount of charge transferred, and t is the time taken.

What is the relationship between electric current and fields? When a charged particle moves through a magnetic field, a force is exerted on it. This force is proportional to the particle's velocity, as well as the magnetic field strength and the charge's magnitude.

The mathematical equation that describes this relationship is: F = qvB sinθ Where F is the force on the charged particle, q is the charge, v is the velocity, B is the magnetic field strength, and θ is the angle between the velocity vector and the magnetic field vector.

In the wire, the current is directly proportional to the potential difference and inversely proportional to the wire's resistance. Therefore, decreasing the resistance of the wire increases the current in the wire.

The tail shape of a surfboard greatly affected the board's interaction with the wave's face and the flowing of water flowing.

The tail shape of a surfboard affects how the board depends on the wave's face, and the water flowing between it. More comprehensive, thicker tail shapes have more surface area and assist the board to float and create lift - allowing the surfboard to plane over the surface of the water more efficiently.

The shape of both the surfboard and its fin swap the way the water moves around it if you can grab a wave as well as the turning ability of the surfboard.

So we can conclude that Surfboard bottom outlines are also essential. Concave and V-shaped contours have similar performances, for all opposite designs.

The initial speed of the clay target can be determined using the principles of projectile motion. To begin, let's consider the vertical motion of the clay target.

At the maximum height, the vertical velocity of the target is zero since it momentarily stops before falling back down. We can use the equation for vertical motion:

v_f²  = v_i²  + 2 * a * d

where v_f is the final vertical velocity (zero in this case), v_i is the initial vertical velocity, a is the acceleration due to gravity (-9.8 m/s² ), and d is the vertical displacement (4.6 m).

Plugging in the known values, we get:

0 = v_i²  + 2 * (-9.8 m/s² ) * 4.6 m

Simplifying the equation, we have: v_i² = 2 * 9.8 m/s²  * 4.6 m v_i²  = 89.68 m² /s²

Taking the square root of both sides, we find:

v_i = √(89.68 m² /s² ) = 9.46 m/s Now, let's consider the horizontal motion of the clay target. The horizontal velocity remains constant throughout the motion, so we can use the equation:

v_x = v_i * cosθ

where v_x is the horizontal velocity, v_i is the initial velocity, and θ is the launch angle (35°).

Plugging in the known values, we get: v_x = 9.46 m/s * cos(35°) Calculating this, we find: v_x = 9.46 m/s * 0.819 = 7.75 m/s Therefore, the initial speed of the clay target when it is launched is approximately 7.75 m/s.
