The velocity of the ball as it exits the sand is 6m/s.

When the ball rolls into the sand, it experiences a force of friction acting against its motion, which causes it to slow down. The amount of frictional force depends on the properties of the sand and the ball's velocity. Assuming that the ball rolls horizontally into the sand and comes out horizontally as well, the conservation of momentum applies, which means that the momentum of the ball before it enters the sand is equal to the momentum of the ball after it exits the sand.

We can use the equation for conservation of momentum to calculate the final velocity of the ball:

Initial momentum = Final momentum

mv1 = mv2

where m is the mass of the ball, v1 is the initial velocity of the ball, and v2 is the final velocity of the ball.

Substituting the given values, we get:

2 kg x 6 m/s = 2 kg x v2

12 kg m/s = 2 kg x v2

v2 = 6 m/s

Therefore, the final velocity of the ball as it exits the sand is 6 m/s.

The tension is zero when the pendulum is at its highest point (90 degrees with respect to the vertical) and at its lowest point (also 90 degrees with respect to the vertical).

Therefore, the correct answer is: The tension is zero at the angles +90 degrees and -90 degrees.
The tension is never zero.

When a pendulum is swinging, the tension in the string or rod will always be present as it supports the weight of the pendulum bob and provides the centripetal force required for the swinging motion. The tension will be the least when the pendulum is at its lowest point (angle = 0°), but it will never be equal to zero.

The final velocity of the 1.45 kg glider after the collision is approximately 0.3017 m/s.

The momentum before the collision is equal to the momentum after the collision, assuming no external forces act on the system.

The momentum (p) of an object is given by the product of its mass (m) and velocity (v):

p = m * v

Before the collision, the total momentum of the system is:

\(p_{initial} = p_1_{initial} + p_2_{initial}\)

= \(m_1 * v_1 + m_2 * v_2\)

After the collision, the 0.25 kg glider comes to a stop, so its final velocity (\(v_1_{final\)) is 0 m/s. The final velocity of the 1.45 kg glider (\(v_2_{final\)) is what we need to calculate.

Using the principle of conservation of momentum, the total momentum after the collision is:

\(p_{final} = p_1_{final} +\) \(p_2_{final\)

= \(m_1\) * \(m_2_{final\) + \(m_2\) *\(v_2_{final\)

= 0.25 kg * 0 m/s + 1.45 kg * \(v_2_{final\)

Since momentum is conserved, we can equate the initial momentum to the final momentum:

\(p_{initial} = p_{final}\)

\(m_1 * v_1_{initial} + m_2 * v_2_{initial} = m_1 * v_1_{final} + m_2 * v_2_{final}\)

0.25 kg * 1.75 m/s + 1.45 kg * 0 m/s = 0.25 kg * 0 m/s + 1.45 kg * \(v_2_{final\)

0.4375 kg·m/s = 1.45 kg * \(v_2_{final\)

Simplifying the equation, we find:

\(v_2_{final\) = 0.4375 kg·m/s / 1.45 kg

\(v_2_{final\) ≈ 0.3017 m/s

Therefore, the final velocity of the 1.45 kg glider after the collision is approximately 0.3017 m/s.

Main Answer:

The equation acceleration = v/time can be proven using the fundamental definitions of acceleration, velocity, and time. Acceleration is defined as the rate of change of velocity, and velocity is the rate of change of displacement with respect to time. Let's consider an object moving with an initial velocity v0 and final velocity v in a time interval t.

Explanation:

The change in velocity, Δv, can be calculated as the final velocity minus the initial velocity, Δv = v - v0. Similarly, the change in time, Δt, is the final time minus the initial time, Δt = t - t0.

By substituting these values into the equation for acceleration, we have:

acceleration = Δv/Δt

Now, substituting Δv = v - v0 and Δt = t - t0, we get:

acceleration = (v - v0)/(t - t0)

Since v0 and t0 represent the initial velocity and time, respectively, we can rewrite the equation as:

acceleration = (v - v0)/t

By rearranging the equation, we find:

acceleration = v/t

Thus, we have proved that acceleration is equal to v/time.

Answer:

a. Hooke's law is a principle in physics that states that the force required to extend or compress a spring or elastic material is directly proportional to the displacement of its end or deformation.

b. The formula for resistance of a wire is given by:

R = (ρL)/A

where R is resistance, ρ is resistivity, L is length, and A is cross-sectional area.

Given L = 10m, A = 0.1 mm² = 0.1 x 10^-6 m², and ρ = 50 µcm = 50 x 10^-8 Ωm, we have:

R = (50 x 10^-8 x 10) / (0.1 x 10^-6)

R = 5 Ω

Therefore, the resistance of the wire is 5 Ω.

The formula for Young's modulus is given by:

Y = F L / A ΔL

where Y is Young's modulus, F is force, L is length, A is cross-sectional area, and ΔL is the change in length.

Given F = 2 kgf = 2 x 9.81 N, L = 2 m, d = 0.64 mm = 0.64 x 10^-3 m, and ΔL = 0.60 mm = 0.60 x 10^-3 m, we have:

A = πd²/4 = π(0.64 x 10^-3)²/4 = 3.21 x 10^-7 m²

Y = (2 x 9.81 x 2) / (3.21 x 10^-7 x 0.60 x 10^-3)

Y ≈ 1.24 x 10^11 N/m²

Therefore, the Young's modulus of the wire is approximately 1.24 x 10^11 N/m².

The winds aloft chart for the Great Lakes (Michigan is fine) region displays the wind direction and speed at several altitudes. At 3000 feet, the wind speed is approximately 17 knots.

At 12,000 feet, the wind speed is about 44 knots. The wind speed at FL350 is approximately 67 knots.Surface friction has an effect on the winds close to the ground, slowing them down due to the frictional force exerted on the ground by air molecules. The winds shift direction with altitude, veering to the right of the direction of travel in the northern hemisphere. The approximate location of the Jetstream can be obtained by examining the wind/temperature plot chart. The fastest wind speed at FL360 appears to be approximately 145 knots, traveling towards the northeast. Flight to the east or southeast would benefit from this wind speed.Seasonally, winds aloft change depending on the position of the jet stream, which moves towards the poles during the summer months and towards the equator during the winter months.

A planes average speed between two cities is 610 km/hr. If the trip takes 2. 25 hrs, then the distance covered by a plane is  1372.5 kilometers.

To calculate the distance the plane flies, we can use the formula:

Distance = Speed × Time

Given that the average speed of the plane is 610 km/hr and the trip takes 2.25 hours, we can substitute these values into the formula to find the distance.

Distance = 610 km/hr × 2.25 hrs

To multiply these values, we need to align the units correctly. By canceling out "hrs" in the numerator and denominator, we get:

Distance = 610 km × 2.25

Multiplying 610 km by 2.25 gives us:

Distance = 1372.5 km

When the electrons flow off one conducting plate, that plate becomes positively charged. Simultaneously, the other plate will be negatively charged. The excess charges on one plate will interact with the excess charge on the other plate via the force of attraction between opposite charges.

This interaction between the excess charges is due to the fundamental property of electric charges. Like charges repel each other, while opposite charges attract each other. In this case, the positive charges on one plate attract the negative charges on the other plate, and vice versa.

To understand this better, imagine two conducting plates, Plate A and Plate B, placed close to each other. Initially, both plates have an equal number of electrons and protons, resulting in no net charge. When electrons flow off Plate A, it becomes positively charged as it loses negatively charged electrons. These excess positive charges on Plate A will now attract the excess negative charges on Plate B.

Conversely, the excess negative charges on Plate B will attract the excess positive charges on Plate A. This mutual attraction between the opposite charges on the two plates creates an electric field between them.

In summary, the excess charges on one conducting plate interact with the excess charges on the other plate via the attractive force between opposite charges. This interaction is a result of the fundamental property of electric charges and leads to the creation of an electric field between the plates.

Answer:       If you let a helium balloon go, and if, as it rises, it stays at a constant temperature, the volume of the balloon will. The magnitude of the buoyant force is equal to the weight of the amount of fluid that has the same total volume as the object.

If you let a helium balloon go, it rises, it stays at a constant temperature, the volume of the balloon will increases.

A measurement of three-dimensional space is volume. Several imperial or US customary units, as well as SI-derived units (such the cubic meter and liter), are frequently used to quantify it quantitatively (such as the gallon, quart, cubic inch). Volume and length (cubed) have a symbiotic relationship.

The density for helium remains lower than that of air, therefore when the balloon is inflated with that as well, it rises. The atmosphere's pressure continues to drop as it rises, which causes the internal pressure to rise. The balloon's volume of the balloon will increase.

Therefore, the volume of the balloon will increase.
