Remember, there's 2 types of accelaration formula.

1st formula :

a = ( final speed - initial speed ) ÷ time

2nd formula :

resultant force (f) = mass × a

or

a = resultant force (f) ÷ mass

So the ans shld be,

a = 50 x 150

= 7500 m/s²

The acceleration of the body is 0.33 m/s².

Acceleration of an object having mass is defined as the net force acting on the object per unit mass.

Here,

Mass of the body, m = 150 kg

Force acting on the body, F = 50 N

The net force acting on an object is defined as the product of mass and acceleration of the object.

The expression for the net force acting on the body is given by,

F = ma

Therefore, the acceleration of the body,

a = F/m

Applying the values of F and m,

a = 50/150

a = 0.33 m/s²

Hence,

The acceleration of the body is 0.33 m/s².

The time for the planet to orbit the Sun is 1 Earth year. use kepler's law, which states that the square of the time, t, required for a planet to orbit the sun varies directly with the cube of the mean distance.

Using Kepler's law, which states that the square of the time required for a planet to orbit the Sun varies directly with the cube of the mean distance, we can determine the time for a planet with a mean distance of 9.58 astronomical units (a.u.) to orbit the Sun.

According to Kepler's law, the relationship period between the time (t) and the mean distance (a) is expressed as:

\(t^2 = k * a^3\)

where k is a constant.

Given that the mean distance of the planet is 9.58 a.u. and the Earth's distance is 1 a.u., we can set up the following equation:

(1)² = k × (9.58)³

Simplifying the equation, we have:

1 = k × (9.58)³

To solve for the constant k, we divide both sides by (9.58)³:

k = 1 / (9.58)³

Now, we can substitute the mean distance of the planet (9.58 a.u.) into the equation to calculate the time (t):

t² = (1 / (9.58)³) × (9.58)³

Simplifying further, we get:

t² = 1

Taking the square root of both sides, we find:

t = 1

Explanation:

The mass of a ball is 3.5 kg. It moves down a slope that is inclined at 40 degrees with respect to the horizontal. The base of the slope has a length of 4.8 meters.the ball loses 106.2 Joules of gravitational potential energy when it rolls down the slope.

It is required to determine how much gravitational potential energy the ball loses when it rolls down the slope.For this, we need to use the following formula:ΔPE = mghwhere m = mass of the ball = 3.5 kgg = acceleration due to gravity = 9.81 m/s2h = height from which the ball rolls downLet's analyze the situation. The ball moves down a slope. The potential energy (PE) of the ball at the top of the slope is converted into kinetic energy (KE) as it moves down the slope. The ball gains KE, and it loses PE.The height from which the ball rolls down the slope is given by the following expression:h = length of slope × sin θh = 4.8 × sin 40°h = 3.086 metersSubstitute the given values into the formula for ΔPE.ΔPE = mghΔPE = 3.5 × 9.81 × 3.086ΔPE = 106.2 JoulesTherefore, the ball loses 106.2 Joules of gravitational potential energy when it rolls down the slope.

Answer:

 a = 10 ρ_air g \(\frac{\Delta P}{m P_o}\)

Explanation:

Let's solve this problem in parts, with the initial data the camera rises slowly, so we can assume that at constant speed, we apply the equilibrium condition

         B - W = 0

The thrust is given by Archimedes' law

         B = rho_aire g V_body

The volume of the body can be found from the ideal gas ratio

         P V = n R T

let's use the subscript "o" for the initial concisions

         V₀ = (nR) T₀/P₀               1

we substitute

          10 ρ_air g (nR) T₀ /P₀ = W

when the storm approaches the pressure decreases, P

If we use the ideal gas equation

           V = (nR) T₀ / P

we combine this equation with equation 1

            V = V₀P₀ / P

if we write the pressure

             P = P₀ -ΔP

we substitute

            V = \(\frac{V_oP_o}{P_o - \Delta P} =V_o \ ( 1 - \frac{\Delta P}{P_o} )^{-1}\)

we expand serie  and eliminate higher order terms

            V = V₀ (\(1+ \frac{\Delta P}{Po}\))

with this expression we can write the thrust

             B = B₀ + ΔB

Newton's second law for the new conditions is

             B - W = m a

             (B₀ + ΔB) - W = ma

              ΔB = m a

              a = ΔB / m

              a = 10 ρ_air g \(\frac{\Delta P}{m P_o}\)

This is the initial acceleration of the camera

Seismic waves are sent from the AP center in an earthquake. Waves move through various materials in a variety of orientations. The seismic waves would go forth at the same pace in all directions, which would be true for everyone who felt the ground trembling. Here option A is the correct answer.

When an earthquake occurs, it generates seismic waves that travel through the Earth's layers and cause the ground to shake. These waves propagate in different directions and interact with the media they encounter, including rock, soil, and water. As a result, the shaking experienced by people who feel the earthquake may vary depending on their location and the type of surface they are standing on.

Out of the given options, only option A can be considered true for all people who feel earth-shaking. This is because seismic waves travel outward from the epicenter in all directions at the same speed, regardless of the type of surface they encounter. However, the other options are not necessarily true for all observers.

Option B, which suggests that the amplitude of the shaking will be the same for all observers, is not accurate because the intensity of the shaking can vary depending on factors such as the distance from the epicenter, the direction of propagation, and the type of soil or rock that the seismic waves encounter.

At a height of 6.37 10⁶ meters above the Earth's surface, the astronaut's weight is 195.5 N.

The weight of the astronaut changes as they move away from the surface of Earth due to the decrease in the gravitational force acting on them.

Use the formula:

F = Gm₁m₂/r²

where F = gravitational force,

G = gravitational constant,

m₁ = mass of the Earth,

m₂ = mass of the astronaut, and

r = distance between the center of the Earth and the astronaut.

Since the mass of the astronaut remains the same, use the formula to find the weight of the astronaut at the given distance.

First, calculate the distance from the center of the Earth to the astronaut:

r = radius of the Earth + height above the surface

r = 6,371,000 m + 6,370,000 m = 12,741,000 m

Calculate the gravitational force acting on the astronaut:

F = Gm₁m₂/r²

F = (6.6743 × 10⁻¹¹ N m²/kg²) x (5.972 × 10²⁴ kg) x (80 kg) / (12,741,000 m)²

F = 195.5 N

Explanation:

The primary filter selects the specific wavelength and the secondary filter selects the emitted wavelength.

In fluorescence microscopy, two filters are used to selectively excite and detect fluorescent molecules. The primary filter, also known as the excitation filter or the excitation wavelength selector, is used to select the specific wavelength of light that is used to excite the fluorescent molecules. The primary filter allows only the specific wavelength of light to pass through, which is then focused on the sample. Once the fluorescent molecules are excited, they emit light at a longer wavelength. The secondary filter, also known as the emission filter or the emission wavelength selector, is used to selectively detect this emitted light. The secondary filter blocks any light emitted by the excitation light source and allows only the emitted fluorescence to pass through to the detector. The primary and secondary filters are carefully selected to match the fluorescent properties of the sample being imaged. The choice of filters can affect the sensitivity, specificity, and resolution of the fluorescence microscopy image. Therefore, it is important to choose the appropriate filter sets for each specific experiment and application.

ANSWER:

The two movements the turning of the top and the movement of the Earth appear in rotating bodies and are the basis of the gyroscope.

STEP-BY-STEP EXPLANATION:

Depending on whether the top is launched, vertical or inclined, two movements are obtained: the sleeping top or the top that, in addition to turning on itself, describes a circumference, as if it were the Earth around the sun. In the sleeping top, the axis of rotation is perpendicular to the plane (ground) on which you dance. If the top is perfectly symmetrical, its center of gravity must be located at an interior point through which the virtual axis of rotation passes. But, because the top, by mass or construction, is not totally symmetrical, as it loses speed, its axis of rotation tilts and begins to rotate, describing a cone, whose vertex is the tip of the top.

In conclusion, the two movements the turning of the top and the movement of the Earth appear in rotating bodies and are the basis of the gyroscope.

Hi there!

We can use the work-energy theorem to solve.

Recall that:
\(E_i = E_f\)

The initial energy equals the final energy (Conservation of Energy). However, we must take into account energy dissipated due to friction in this instance.

The energy lost due to friction is equivalent to the work done by friction. Recall the following:

The work due to a force is:
\(W = F \cdot d \\\)

Since the displacement is in the same direction as the force, the dot-product becomes Fd.

The work due to friction then becomes:

\(W_f = \mu mgdcos\theta\)
The work due to friction is SUBTRACTED from the initial potential energy.

Initial energy = GPE = mgh

Final energy = KE

Therefore:

\(\boxed{mgh - \mu mgdcos\theta = KE}\)

The toy train and the car move off together at speed of 0.4 m/s.

According to the law of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.

From conservation of momentum, we get:

Total initial momentum = total final momentum

0.1 kg × 1.0 m/s + 0.15 kg × 0 m/s = ( 0.1 kg + 0.15 kg) × v

v  = (0.1/0.25) × 1.0 m/s

Answer:

The value is \(t = 5.124 \ s\)

Explanation:

From the question we are told that

   The height of the tree is \(s = 20 \ m\)

    The angle the ball leaves is  \(\theta = 45^o\)

    The initial velocity  is  \(u = 30.0 \ m/s\)

Generally the vertical of the ball's initial velocity is mathematically evaluated as

      \(u_y = u * sin (45)\)

=>   \(u_y =- 30 * sin (45)\)

=>   \(u_y = -21.21 \ m/s\)

Here  \(u_y\) is negative because it is in the direction of the negative y-axis

Generally from kinematic equation we have

      \(s = u_yt + \frac{1}{2} g t^2\)

=>   \(20= -21.21 t +4.9 t^2\)

=>   \(4.9 t^2 -21.21 t- 20= 0\)

Solving using quadratic formula we have that

        \(t = 5.124 \ s\)
