Explanation:

Answer:

35°

Explanation:

By laws of reflection,

Angle of incidence = Angle of reflection

Angle between incident ray and reflected ray = 70°

Angle of incidence + Angle of reflection = 70°

Since,

Angle of incidence = Angle of reflection

Angle of incidence + Angle of incidence = 70°

2 Angle of incidence = 70°

Divide 2 on both sides,

Angle of incidence = 70° / 2

Angle of incidence = 35°

The statement is true because the buoyancy force is directly proportional to gravitational acceleration, and Earth's gravitational acceleration is greater than Mars'.

1. Buoyancy force is given by the formula: F_b = V * ρ * g, where F_b is the buoyancy force, V is the volume of the submerged object, ρ is the density of the fluid, and g is the gravitational acceleration.
2. The volume (V) and density (ρ) of the fluid remain constant for both Earth and Mars, as they are inherent properties of the fluid and object.
3. The gravitational acceleration (g) is greater on Earth than on Mars.
4. Therefore, the buoyancy force (F_b) experienced by a block submerged in water on Earth will be greater than that on Mars due to the greater gravitational acceleration on Earth.

A block submerged in water experiences greater buoyancy force on Earth compared to Mars due to Earth's higher gravitational acceleration.

The solar insolation in the visible and infrared regions of the solar electromagnetic spectrum is much more than the energy that space weather occurrences release into the troposphere and stratosphere. Despite claims to the contrary, there may be some connection between the Earth's climate and the 11-year sunspot cycle. There is no proof of this. For instance, it has frequently been suggested that the Maunder minimum, a 70-year period almost devoid of sunspots, is correlated to a cooler climate, but these correlations have vanished after further research.

"his performing the first successful heart surgery" - This is the correct choice.

The calculated root mean square (RMS) velocity of Cl₂ at -23.0°C is approximately 412 m/s.

To calculate the RMS velocity, we can use the following formula: v(rms) = √((3 * R * T) / (M))Where:- v(rms) represents the root mean square velocity - R is the ideal gas constant (8.314 J/(mol·K))- T is the temperature in Kelvin (K) - M is the molar mass of the gas in kilograms per mole (kg/mol) First, we need to convert the temperature from Celsius to Kelvin: T(K) = T(°C) + 273.15 T(K) = -23.0°C + 273.15 T(K) ≈ 250.15 K The molar mass of Cl₂ is 70.906 g/mol, which is equivalent to 0.070906 kg/mol. Now, we can substitute the values into the formula to calculate the RMS velocity: v(rms) = √((3 * 8.314 J/(mol·K) * 250.15 K) / (0.070906 kg/mol)) v (rms) ≈ 412 m/s Therefore, the root mean square velocity of Cl₂ at -23.0°C is approximately 412 m/s.

Answer:

Acceleration, a = 24m/s²

Explanation:

Given the following data;

Initial velocity = 0

Final velocity = 60

Distance =75

To find the final velocity of the object, we would use the third equation of motion;

\( V^{2} = U^{2} + 2aS \)

Where;

V represents the final velocity measured in meter per seconds.

U represents the initial velocity measured in meter per seconds.

a represents acceleration measured in meters per seconds square.

Substituting into the equation, we have;

\( 60^{2} = 0^{2} + 2a*75 \)

\( 3600 = 150a \)

\( a = \frac {3600}{150} \)

a = 24m/s²

Acceleration, a = 24m/s²

The Lagrangian is then given by L = T - V.

(a) Writing down the Lagrangian (L): The Lagrangian is the difference between the kinetic and potential energies of the system.

In this case, the particle is confined to move on the surface of a circular cone, so we need to express the kinetic and potential energies in terms of the spherical polar coordinates (r, θ).

The kinetic energy can be expressed as T = (1/2) m (dr/dt)^2 + (1/2) m r^2 (dθ/dt)^2, where m is the mass of the particle.

The potential energy can be expressed as V = m g r cosθ, where g is the acceleration due to gravity.

The Lagrangian is then given by L = T - V.

(b) Finding the equations of motion: The equations of motion can be obtained by applying the Euler-Lagrange equations to the Lagrangian L.

This involves taking partial derivatives of L with respect to the generalized coordinates (r, θ) and their derivatives (dr/dt, dθ/dt), and then solving the resulting equations.

One of the resulting equations of motion will be related to the angular momentum tz. It can be interpreted as the conservation of angular momentum around the z-axis.

The r equation of motion can be used to eliminate θ from the r equation, in favor of a constant fz.

The r equation should make physical sense even when θ = 0.

To find the value ro of r at which the particle can remain in a horizontal circular path, you would need to analyze the equilibrium conditions of the system and solve for r.

(c) Analyzing stability and frequency of oscillation: By assuming r(t) = ro + E(t), where E(t) is a small radial perturbation from the equilibrium position ro, you can substitute this expression into the r equation of motion to determine whether the circular path is stable.

Stability can be determined by examining the behavior of the perturbation E(t) over time.

The frequency of oscillation about ro can be obtained by analyzing the form of the solution E(t) and determining the frequency at which it oscillates.

Answer:

Greater

Explanation:

The longer the handle the greater the mechanical advantage and the greater the increase in force that is applied to the bolt.

Mechanical advantage can be said to be the rate at which a particular force is multiplied.

This then means that there is a comparison between the output force and that of the input force.

The longer the handle gets, the more the mechanical advantage of the bolt and this also translates to it requiring lesser force being applied on it..

The speed of a ball that is thrown upward into the air, neglecting air resistance, changes over time due to the force of gravity. The ball's velocity decreases as it rises, reaches zero at the peak of its trajectory, and then increases as it falls back towards the ground.

The motion of an object under the influence of gravity can be described by the laws of physics. When a ball is thrown upward into the air, it initially moves with a certain velocity. However, as the ball rises, its velocity changes due to the force of gravity acting on it. In this answer, we will neglect the effect of air resistance and focus solely on the effect of gravity.

When a ball is thrown upward, it has an initial velocity, which is equal to the magnitude of the velocity with which it was thrown. This velocity is positive, meaning that it points in the upward direction. However, as the ball rises, it is slowed down by the force of gravity, which acts in the downward direction. As a result, the velocity of the ball decreases over time.

The acceleration due to gravity, g, is a constant 9.8 m/s^2, and it acts in the downward direction. The equation for velocity, v, as a function of time, t, can be expressed as v = v0 - gt, where v0 is the initial velocity. This equation shows that the velocity of the ball decreases linearly with time as it rises into the air.

At the peak of its trajectory, the ball has zero velocity. This means that it is momentarily at rest, and from this point on, it begins to fall back towards the ground. The velocity of the ball at this point is negative, meaning that it points in the downward direction. As the ball falls, its velocity increases due to the force of gravity, and it continues to increase until it reaches the ground.

High-intensity interval training (HIIT) can be included in a training plan to improve anaerobic power in a 16-year-old sprinter.

Anaerobic power is the ability to perform short, high-intensity bursts of activity without relying on oxygen. HIIT involves alternating periods of high-intensity exercise with periods of rest or lower intensity exercise. This type of training has been shown to improve anaerobic power in athletes. A track coach may design a HIIT program that includes sprints, plyometric exercises, and resistance training to improve the sprinter's power and speed.

However, it is important for the coach to consider the individual athlete's current fitness level and adjust the intensity and volume of the program accordingly to avoid injury and overtraining. Adequate rest and recovery time should also be included in the training plan to allow for proper adaptation and improvement in performance.
