Considering the equivalence between mass and energy given by the expression of Einstein's theory of relativity, the correct answer is the last option: the energy equivalent of an object with a mass of 1.05 kg is 9.45×10¹⁶ J.

The equivalence between mass and energy is given by the expression of Einstein's theory of relativity, where the energy of a body at rest (E) is equal to its mass (m) multiplied by the speed of light (c) squared:

E=m×c²

This indicates that an increase or decrease in energy in a system correspondingly increases or decreases its mass, and an increase or decrease in mass corresponds to an increase or decrease in energy.  

In other words, a change in the amount of energy E, of an object is directly proportional to a change in its mass m.

In this case, you know:

Replacing:

E= 1.05 kg× (3×10⁸ m/s)²

Solving:

E= 9.45×10¹⁶ J

Finally, the correct answer is the last option: the energy equivalent of an object with a mass of 1.05 kg is 9.45×10¹⁶ J.

We know that the vertical clearance of the crossbar by the ball is x=1.57m.

From a point 36.0 m from the goal, a place kicker must kick a football. The ball must clear the 3.05 m-high crossbar as a consequence of the kick. The ball kicks off the ground with a speed of 20.0 m/s at an angle of 53° from the horizontal.

v=18cos48 m/s

Time is therefore defined as distance multiplied by speed, which equals 28/18cos48 divided by 48, or 2.324

The required work against gravity to construct a solid rectangular box with a height of 4m and square base with side lengths of 2m using lightweight material whose density is 700 kg/m³ can be determined through the following method:

work against gravity is 5.6 × 10³ J Formula: The weight of the object = m × g, where m = mass of the object and g = acceleration due to gravity.W = F × d, where W = work done, F = force applied, and d = distance traveled.A solid rectangular box has a height of 4m and a square base of 2m. Therefore, the volume of the box is V = 2m × 2m × 4m = 16 m³Given the density of the lightweight material is 700 kg/m³, then the mass of the box is:mass = density × volume = 700 kg/m³ × 16 m³ = 11200 kg

The weight of the box is:Weight = m × g = 11200 kg × 9.8 m/s² = 109760 NTo lift the box, a force equal to the weight of the box must be applied over a distance equal to the height of the box. Therefore, the work done is given by:W = F × d = Weight × height = 109760 N × 4 m = 439040 JHowever, the box is made of a lightweight material, therefore, the required work against gravity is less.

Explanation:

J.J. Thomson discovered the existence of electrons in the cathode ray, which was a beam of negatively charged particles emitted by the cathode in a vacuum tube.

Specifically, he found that the beam could be deflected by an electric or magnetic field, indicating that it was composed of charged particles. By measuring the deflection of the beam and applying equations related to electric and magnetic fields, he was able to determine the charge-to-mass ratio of the particles, which was much smaller than that of any known atom. This led him to propose that the particles were subatomic and he called them "corpuscles", which we now refer to as electrons.

This discovery was significant in the development of atomic theory and laid the foundation for future work on the structure of atoms and the nature of subatomic particles.

Beta emission

Gamma radiation emission

Gamma radiation results in the emission of gamma ray . This is a very high frequency radiation . It is not a particle having charge and mass like alpha and beta emission . So it has no effect on the mass and charge of the product that is formed after gamma radiation . The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product . It causes negligible change in the mass of the product and no change in the charge of the product.

That is why , generally this product is not written in the nuclear reaction .

Answer:

The answer is Gamma ray

Explanation:

Because this is a very high frequency radiation, is not a particle having charge and mass like alpha and beta emission, so it has no effect on the mass and charge of the product that is formed after gamma radiation. The only effect it has on the product is that it reduces the kinetic energy of the emitting particles or it reduces the internal energy of the product, it causes negligible change in the mass of the product and no change in the charge of the product.

The merry-go-round takes approximately 29.41 seconds to complete 2.00 rotations.

Given data:

Acceleration (α) = 0.135 rad/\(s^2\)

Number of rotations (θ) = 2.00

To find the time taken (t) for 2.00 rotations, we need to use the formula:

θ = 0.5 * α * \(t^2\)

Rearranging the formula, we get:

\(t^2\) = (2 * θ) / α

Plugging in the given values, we have:

\(t^2\) = (2 * 2.00) / 0.135

\(t^2\) = 29.63

Taking the square root of both sides, we find:

t ≈ √29.63

t ≈ 5.439

Therefore, the time taken for the merry-go-round to complete 2.00 rotations is approximately 5.439 seconds.

Note: It's important to round the final answer to an appropriate number of significant figures, considering the given data. In this case, we have used four significant figures in the final answer.

However, if we want to adhere to the given significant figures in the acceleration (0.135 rad/\(s^2\)), the answer should be rounded to three significant figures. In that case, the final answer would be approximately 5.44 seconds.

Explanation:

Problem-Solving Strategy 7.1: Rotational Dynamics Problems Rotational dynamics is the study of rotational motion, which is movement about an axis or a pivot point. We'll look at a few sample problems that illustrate the procedure to approach and resolve rotational dynamics problems in this article. The below diagram depicts the scenario given: At an angle of 10 degrees, the pencil starts to fall. We need to determine the angular acceleration. The given problem does not provide the mass, length or other physical quantities of the pencil. Therefore, we assume that the pencil is a point mass with a negligible size. The torque equation is used to solve rotational motion issues.

It is given as follows: τ = Iα where τ is torque, I is moment of inertia and α is angular acceleration. Let's use this equation to solve the problem. Ignoring air resistance, the only force acting on the pencil is the gravitational force, which acts on the center of mass of the pencil. The gravitational force can be broken down into two components, mgcosθ and mgsinθ, where m is mass, g is acceleration due to gravity, θ is the angle of the pencil with respect to the vertical axis. Let's determine the direction of torque produced by these forces.(i) mgcosθ is acting on the center of mass of the pencil. As it is acting along the vertical line passing through the pivot point, the torque produced is zero.(ii) mgsinθ is acting at a perpendicular distance r from the pivot point.

The direction of torque produced by this force is counterclockwise, hence, positive magnitude. To find the angular acceleration, let's use the torque equation.τ = Iα= F  = mr²α (Moment of inertia of point mass)α = τ / Iα = mgsinθ * r / (mr²)α = gsinθ / r Let's insert the values. g = 9.8 m/s²θ = 10.0°r = length of the pencil = unknown Here, the length of the pencil is unknown. If we take r as the length of the pencil and find the value of angular acceleration, it will be true only for this angle (10.0 degrees) because torque, and hence, angular acceleration, varies with respect to the length of the pencil. It will not be true for other angles. The relationship between the angle and the length of the pencil is given by the trigonometric function sinθ = r / L.α = gsinθ / rα = g / Lα = 9.8 / L radians/s²The angular acceleration is inversely proportional to the length of the pencil. This implies that the shorter the length of the pencil, the greater the angular acceleration and the longer the length of the pencil, the smaller the angular acceleration. Therefore, when we try to balance the pencil for a longer time, we need to use a smaller angular acceleration, so we need to keep the pencil vertical.

A car starts to rest on a bend with a radius of 130 m and a tangential acceleration of 1.3. When the total acceleration of the car is 2.0m/s2, the car will move through an angle of 22.5°.

The turning radius is the distance required by the car to turn or turn around. Because of this, calculations are made from the moment the car makes a turn until it rotates in a semicircle or 180 degrees. Then, the distance from the diameter will be measured and used as the turning radius of the vehicle.

Radial acceleration (a') = √2² - √1.3²

Radial acceleration (a') = √4 - √1.69

Radial acceleration (a') = √2.31

Radial acceleration (a') = 1.5 m/s²

v = \(\sqrt{a' . r}\)

v = \(\sqrt{1.5 x 130}\)

v = \(\sqrt{195}\)

v = 14 m/s

Now,

d = v²/2a'

d = 14²/2(1.5)

d = 154/3

d = 51.3 m
