The maximum height the shot will reach is 3.08 m (2.20 m + 68.0 cm).

Calculate the initial velocity of the shot. Since the shot is initially at rest, the initial velocity is 0 m/s.

Calculate the time it takes for the shot to reach the maximum height. This can be calculated using the formula: t = (vf - v0) / a, where vf is the final velocity, v0 is the initial velocity, and a is the acceleration. In this case, vf = 0 m/s, v0 = 0 m/s, and a = 40.0 m/s2. Therefore, t = 0 / 40.0 m/s2 = 0 s.

Calculate the maximum height the shot will reach. This can be calculated using the formula: h = v0t + (1/2)at2. Since v0 = 0 m/s, t = 0 s, and a = 40.0 m/s2, h = 0 + (1/2)(40.0)(0)2 = 0 m. Therefore, the maximum height the shot will reach is 0 + 2.20 m = 2.20 m + 68.0 cm = 3.08 m.

A thermometer measures an average kinetic energy of a substance - Correct

Heat is a form of energy - Correct

Convection occurs only in liquids and gases - Incorrect (Convection can occur in both liquids and gases, but it can also occur in solids).

All substances radiate heat- correct

Our body temperature is always equal to the temperature around us - Incorrect ( the body can be influenced by the external temperature, it is not always equal to it and has its own mechanisms to regulate its internal temperature), Heat flows from a colder substance to a hotter substance - Correct (This is the second law of thermodynamics). It occurs due to the density differences in a fluid caused by temperature variations. As a fluid is heated, its density decreases, causing it to rise. Cooler fluid, which is denser, then flows into the region left by the rising warm fluid, and the cycle repeats, creating a convection current.

There are two main types of convection: Natural convection, which occurs in the absence of any external forcing. Forced convection, where an external force, such as a pump or a fan, is used to drive the fluid motion and enhance heat transfer.

Equation 2.3 is derives using

For a projectile motion, in all the equations of motion we take a = g = 9.81 m/s², since the only acceleration that a projectile has is that due to gravity.

The value of acceleration due to gravity is calculated using

The radius of curvature of an electron in a magnetic field is given by the equation:

Knowing the radius of curvature and the charge and mass of an electron, magnetic field we can rearrange the equation to find the velocity:

Substituting the known values:

v = (1.6 x 10⁻¹⁹ C) * (B) * (26.0 cm) / (9.11 x 10⁻³¹ kg)

Since the electron is accelerated by a potential difference of 3000V, we can calculate its kinetic energy using the equation:

and then use that to find the velocity:

K = eV = 0.5 * m * v²,

Solving for v:

v = √(2 * eV / m) = √(2 * (1.6 x 10⁻¹⁹ C) * (3000 V) / (9.11 x 10⁻³¹ kg)) = 7.66 x 10⁷ m/s.

Thus;

The repulsion force between two electrons can be calculated using Coulomb's law, which states that the force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. The formula for the force is given by:

F = k * (q1 * q2) / r^2

where F is the force in newtons, k is the Coulomb constant (8.99 x 10^9 N m^2/C^2), q1 and q2 are the magnitudes of the charges in coulombs, and r is the distance between them in meters.

Since electrons have a negative charge, the force between them is repulsive. If each student loses 0.01% of their electrons, the force can be calculated as follows:

q1 = q2 = (0.01%) * (1.6 x 10^-19 C) = 1.6 x 10^-21 C

r = 10 m

Substituting these values into the formula gives:

F = k * (q1 * q2) / r^2 = 8.99 x 10^9 N m^2/C^2 * (1.6 x 10^-21 C)^2 / (10 m)^2 = 1.11 x 10^-11 N

Converting the force from newtons to kilo-newtons gives:

F (in kn) = F (in N) / 1000 N/kn = 1.11 x 10^-11 N / 1000 N/kn = 1.11 x 10^-14 kn

The forces acting on block 1 can be analyzed as follows:

The gravitational force acting downwards: m1 * g (where g = 9.8 m/s^2)

The normal force acting upwards: N = m1 * g * cos(theta)

The frictional force acting up the incline: f

By Newton's second law, the net force acting on block 1 is equal to its mass times acceleration:

m1 * a = m1 * g * sin(theta) - f

Where a is the acceleration of block 1. Since the block is not moving, the acceleration must be zero:

0 = m1 * g * sin(theta) - f

Solving for the magnitude of the frictional force, we get:

f = m1 * g * sin(theta) = m1 * 9.8 m/s^2 * sin(theta)

The net force acting on block 2 is equal to its mass times acceleration, which must be equal and opposite to the net force acting on block 1 to balance the tension in the string:

The angle of projection of the fired projectile is θ = sin⁻¹[tex]\frac{(g*R)}{(6*V_{0} ^{2} )}[/tex]/2

The horizontal range of a projectile is given by the equation:

R = V₀² * sin(2θ) / g

where R is the horizontal range, V₀ is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity (approximately 9.8 m/s²).

Given that the horizontal range is equal to 12 times the maximum height, we can use the following equation for the maximum height:

H = V₀² * sin²(θ) / 2g

So, we can substitute the expression for H into the equation for R to get:

R = 12 * V₀² * sin²(θ) / 2g

Now we can equate the two expressions for R and solve for θ:

R = V₀² * sin(2θ) / g = 12 * V₀² * sin²(θ) / 2g

2g * R = V₀² * sin(2θ) = 12 * V₀² * sin²(θ)

Projectile motion is a type of two-dimensional motion, meaning that it can be described by the movement of the object in two perpendicular directions, typically referred to as the horizontal and vertical directions. In the absence of air resistance, the motion of a projectile is determined solely by the force of gravity acting upon it.

The trajectory of a projectile can be predicted using the equations of motion and can be visualized as a parabolic path. The maximum height reached by a projectile, its range, and the time it takes to reach the ground can be calculated using these equations.

The piece of wood does not sink in water because the density of wood is less than that of water.

The density of a substance indicates how dense it is in a given area. Mass per unit volume is the definition of a material's density. In essence, density is a measurement of how closely stuff is packed. It is a particular physical characteristic of a specific thing.

If the density of any material is less than any liquid, it does not sink. As  the density of wood is less than that of water, the piece of wood does not sink in water.
