The separation between the first maxima for red light (λ = 700nm) and violet light (λ = 400nm) = 80 x 10⁻⁵ cm

Light interference is a condition when two or more light waves combine to form a combined light wave. The condition for this light interference is that the light waves come from a coherent source, so that the amplitude, wavelength, and frequency are the same, and the phase difference is always fixed.

Momentum measured relativistically is greater than momentum measured classically for an object travelling at a high speed.

When there is no net external force acting on a system, momentum is preserved according to classical mechanics. As a result, momentum conservation can be used as a fundamental technique to study collisions. Since relativistic momentum is conserved, a lot of what we know about subatomic structure comes from studying the collisions of relativistic particles created by accelerators. The perceptual sense of classical momentum and relativistic momentum are identical. Large masses moving at high speeds are best for it. The conservation of momentum is guaranteed in all inertial frames by the definition of relativistic momentum.

We understand temperature as the average translational kinetic energy linked to the disordered motion of atoms and molecules, and the kinetic temperature as derived from kinetic theory provides reasonable accuracy. In light of the fact that higher energy molecules are colliding with lower energy molecules and transferring energy to them, it follows naturally that the flow of heat is from a region of high temperature toward a region of lower temperature. Since temperature only measures the kinetic energy portion of internal energy, it is not directly proportional to internal energy, so two objects with the same temperature do not necessarily have the same internal energy (see water-metal example). The three commonly used temperature scales are used to measure temperatures (Celsius, Kelvin, and Fahrenheit).

Answer:

The magnitude of the velocity is 77.7 m/s, and the direction is 53.6°.

Explanation:

To find the magnitude and direction of the velocity, we need to use the Pythagorean theorem and trigonometry. The magnitude of the velocity is given by the square root of the sum of the squares of the horizontal and vertical components:

magnitude = sqrt(46.1^2 + 62.5^2)

magnitude = 77.7 m/s

The direction of the velocity is given by the arctangent of the vertical component divided by the horizontal component:

direction = atan(62.5 / 46.1)

direction = 53.6 degrees

Thus, the magnitude of the velocity is 77.7 m/s, and the direction is 53.6°.

The height of the cliff that a stone is dropped from the top, the splash it made as it hit the water below was heard 5.0 s later is 857.5 m.

Sound can bounce when it hits an object that has a hard surface and is not easily penetrated by waves. Examples of objects that can reflect sound are glass walls, iron, zinc, cave walls, and seabeds.

This reflected sound can be used to measure the depth of the sea or the distance of the walls of the cave passage. One of the uses of sound reflection is to know the depth of the sea or the distance of the cave walls.

The equation to determine the distance is:

s = ½ (v) (t)

s = distance or height

t = time

v = velocity of the sound wave (343 m/s)

We have,

Time  = 5.0 s

Velocity of the sound wave = 343 m/s

So, the height of the cliff:

s = ½ (v) (t)

Newton's first law states that a body at rest or moving uniformly in a straight line will stay in that state until a force is applied to it. According to the second law, a body will accelerate (change in velocity) in the direction of any external force acting on it. The strength of the external force directly correlates with the strength of the acceleration.

When one's body starts storing fat, both the number of fat cell and  the size of existing fat cells increases.

Adipose tissue expands during infancy and adolescence as a result of an increase in fat cell quantity and, to a lesser extent, fat cell size. In spite of a significant turnover (about 10% of the fat cells every year) when body weight is stable, the number of fat cells in adults remains constant over time.

In adults, losing weight primarily affects fat cell size (making them smaller), whereas gaining weight results in an increase in fat cell size and quantity. The bone marrow is a significant source of fat cell regeneration during the course of a person's lifetime.

The time at which the ball remains in the air after it is thrown vertically upward with an initial velocity of 61 feet per second from an initial height of 12 feet is 4 seconds.

Motion that is normal to a defined horizontal surface is often referred to as vertical motion. The height of a ball launched from a certain height while maintaining a constant speed is modeled as h(t) = at²+bt+c where h(t) is the height of the ball, t is time, and a, b, and c are constants.

At the initial height h = 12 feet and t = 0,

12 = a(0)²+b(0)+c

c = 12

Differentiating equation h(t) = at²+bt+c concerning t, we get, [tex]\frac{dh(t)}{dt}&=2at+b[/tex]

Substituting t = 0 and dh(t)/dt = 61, we get,

[tex]\begin{aligned}61&=2a(0)+b\\b&=61\end{aligned}[/tex]

Again differentiating [tex]\frac{dh(t)}{dt}&=2at+b[/tex] concerning t, we get, [tex]\frac{d^2h(t)}{dt^2}=2a[/tex]

The acceleration caused by gravity on Earth is 32 feet per second. Since the ball travels downward, the value becomes negative. Substituting this in the above equation.

Substituting h = 0 in the above equation, the time the ball remains in the air will be,

0 = -16t²+61t+12

Using the quadratic formula,

[tex]\begin{aligned}t&=\frac{-(-61)\pm\sqrt{(-61)^2-4\times16(-12)}}{2\times16}\\t&=\frac{61\pm67}{32}\\t&=\frac{61+67}{32}\;\text{or}\;\frac{61-67}{32}\\t&=4\;\text{or}\;-\frac{3}{16}\end{aligned}[/tex]

What is Force?

Force is an influence that can cause an object to change its motion, direction, shape, or other physical attributes. Forces can be applied to objects, creating a change in their acceleration, velocity, or momentum. Forces can be either contact forces, such as pushing or pulling on an object, or non-contact forces, such as gravity, magnetism, and electricity. Forces can be described in terms of magnitude, direction, and point of application. Magnitude is the strength of the force, direction is the path the force is applied, and point of application is the point on the object where the force is applied. Forces can also be classified as balanced or unbalanced. Balanced forces occur when two forces of equal magnitude and opposite direction act on an object, resulting in no net force. Unbalanced forces occur when two forces of unequal magnitude act on an object, resulting in a net force.

F1 = F2 (L – d)/L

F1 = 240 (4.1 – 0.35)/4.1

F1 = 219.51N

For equillibrium ∑ Fnet = 0

F2 + F1 + mg = 0

mg = F2- F1

m = F2 - F1/ g

m = 2.090Kg
