The standard unit to measure velocity is meter per second (m/s or ms-1). For example, “10 meters per second” is scalar and “10 meters per second West” is vector. Acceleration

Nuclear fusion reactions begin in the main sequence stage of a star's life.

During the main sequence stage, a star is in hydrostatic equilibrium, meaning that the outward pressure of the hot, dense gas at its core is balanced by the inward gravitational force. This balance allows the star to maintain a stable size and luminosity.

At the core of a main sequence star, the temperature and pressure are high enough to initiate nuclear fusion reactions, in which hydrogen nuclei combine to form heavier helium nuclei. These reactions release a large amount of energy in the form of light and heat, which helps to maintain the high temperature and pressure at the core and keep the star in hydrostatic equilibrium.

Explanation:

mark me as brainliest

The amplitude of the vibration with the given equation, y = (0.50) cos (π/2 ×t) is 0.50 m. Thus, option C is correct.

Simple Harmonic motion is defined as the periodic motion of the body resulting from the dynamic equilibrium. It is defined as the motion in which the restoring force is directly proportional to the displacement of the body.

Simple Harmonic Motion is defined as the repetitive back-and-forth motion of the central displacement. The maximum displacement of one side is equal to the maximum displacement of the other side.

The simple harmonic motion. F ∝ -x or a ∝ -x, where F is force and a is the acceleration of the body, and x is the displacement. The maximum displacement of the body is called the amplitude of the motion.

The energy is purely kinetic at its mean positions whereas the energy is purely potential at its extreme ends. The harmonic motion is also called oscillatory motion.

From the given, SHM equation, y = A sin(ωt) where A is the amplitude of the wave and ω is the angular frequency of the wave. In the cosine function,  y = A cos(ωt + Ф) where Ф is the phase change.

Thus, the amplitude of the vibration is 0.50 m. Hence, the correct option is C.

Answer:

we can see object due to reflection of light.

The new gravitational force between the two heavenly bodies is six times the original gravitational force.

The gravitational force between two heavenly bodies can be calculated using Newton's law of universal gravitation;

F1 = G × (m1 × m2) / r²...eq (1)

gravitational constant = G

mass 1 = m1

mass 2 = m2

radius = r

distance between them constant,

we can calculate the new gravitational force F2 using the formula:

F2 = G × (m1 × m2) / r²; where

gravitational constant = G

mass 1 = 2m1 (doubled)

mass 2 = 3m2 (tripled)

radius = r

on substitution,

F2 = G × (2m1 × 3m2) / r²

= G × (6m1m2) / r²

= 6 × G × (m1m2) / r²

⇒ (G × (m1 × m2) / r² = F1 )...from eq. (1)

= 6 × F1

⇒ F2 = 6F1

Therefore, the new gravitational force will be six times the original gravitational force when one mass is doubled and the other mass is tripled.

If one of the masses in a gravitational system is doubled and the other mass is tripled while keeping the distance between the bodies constant, then the new gravitational force will increase by a multiple of:

6 (2 x 3 = 6)

We know from Newton's Law of Gravitation that the gravitational force between two objects is:

F = G * (m1 * m2) / r^2

Where:

F = Gravitational force

G = Universal gravitational constant

m1 = Mass of first object

m2 = Mass of second object

r = Distance between the objects

Since the distance (r) between the two bodies remains constant in the given scenario, it drops out when calculating the change in force.

We are only concerned with how the change in masses affects the force.

Based on the equation, we can see that the gravitational force is directly proportional to the product of the two masses (m1 * m2).

If one mass doubles and the other mass triples, their product will increase by a multiple of 2 x 3 = 6.

Therefore, the new gravitational force between the two heavenly bodies will increase by a factor of 6, compared to the original gravitational force when only one mass was doubled and the other mass tripled, while keeping the distance constant between them.

To determine the equivalent resistance in a circuit, we need to consider the resistors connected in parallel and series. In a series circuit, the equivalent resistance is equal to the sum of all the individual resistances. In a parallel circuit, the equivalent resistance is equal to the reciprocal of the sum of the reciprocals of all the individual resistances.

For example, in a circuit with two resistors of 4 ohms and 6 ohms connected in series, the total resistance would be 10 ohms. In a circuit with the same resistors connected in parallel, the equivalent resistance would be 2.4 ohms.
In more complex circuits, we need to use a combination of series and parallel calculations to find the equivalent resistance. For instance, in a circuit with three resistors connected in series and two in parallel, we first calculate the equivalent resistance of the two parallel resistors using the reciprocal method. Then we add this value to the resistance of the three series resistors to find the total equivalent resistance of the circuit.
It is important to note that the total resistance of a circuit determines the amount of current flowing through it. A higher resistance means less current flows, and a lower resistance means more current flows. The resistance of a circuit also determines the amount of power that can be delivered to a load.
Overall, determining the equivalent resistance of a circuit is an important aspect of circuit analysis and design. It allows us to calculate the current, voltage, and power of the circuit and ensures that it operates efficiently and safely.

A basketball player running at 4.60 m/s directly towards the basket jumps into the air to dunk the ball while maintaining his horizontal velocity.

When the basketball player jumps into the air, he experiences a parabolic trajectory due to the effects of gravity. However, since he maintains his horizontal velocity, his horizontal motion remains unaffected throughout the jump.

The vertical motion of the player can be analyzed using the equations of motion under constant acceleration. The initial vertical velocity is zero, and the acceleration due to gravity is approximately 9.8 m/s². Using these values, we can calculate various parameters of the player's jump.

For instance, the time it takes for the player to reach the peak of his jump can be found using the equation v = u + at, where v is the final vertical velocity (which is zero at the peak), u is the initial vertical velocity, a is the acceleration due to gravity, and t is the time.

The maximum height reached by the player can be determined using the equation h = ut + 0.5at², where h is the height, u is the initial vertical velocity, a is the acceleration due to gravity, and t is the time.

Since the player maintains his horizontal velocity throughout the jump, his horizontal displacement remains the same, which depends on the initial horizontal velocity and the time of flight.

By solving these equations, we can obtain the specific values for the time of flight, maximum height reached, and horizontal displacement of the player during his jump.

The balancing weight needed is 20g

The center of gravity is the average position of the weight of an object. We can fully describe the movement of an object through space in terms of the displacement of the object's center of mass from one place to another and the rotation of the object around its center of mass if it is free to rotate.

Given,

Given radius of wheel rim (R): 20 cm

Center of gravity 1 mm away from axis of rotation (z-axis)

This indicates imbalance on x-y plane,

Now, let's assume unbalanced weight is more towards positive x-axis, hence the center of gravity is towards positive x-direction.

In order to statically balance the mass and bring center of gravity towards z-axis, we need to place similar amount of mass 1 mm in negative x-direction.

But as we know adding huge weight to wheel is always unpreferable so we will add M amount of weight on -20 cm in x-direction.

In order to balance the weight, moment about the central axis should be zero.

∑M₀ = 0

10000g × 1 mm = M × 200 mm

M = 10000/200
