Can anyone Hele please I don't know how to convert the light years in order to get an equation like the one on Alpha Centauri in the picture, but I do know how to log it.

Explanation:

Answer:

When we can get the Kinetic energy from this formula KE= 1/2 M V^2and we can get the potential energy from this formula PE =  M g H

we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so, KE = PE

1/2 MV^2 = M g H

1/2 V^2 = g H

when V is the velocity, g is an acceleration of gravitational force (9.8 m^2/s) and H is the height of the fall (8 m).

∴ v^2 = 2 * 9.8 * 8 = 156.8

∴ v= √156.8 = 12.5 m/s

We have that the instantaneous velocity of the shuttlecock when it hits the ground is

[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

From the question we are told

Assuming the acceleration is still -9.81 m/s2, what is the instantaneous velocity of the

shuttlecock when it hits the ground? Show your work below.

Generally the equation for acceleration  is mathematically given as

[tex]a=v \frac{dv}{dx}\\\\\Therefore\\\\\2ah=v^2-u^2[/tex]

Where

acceleration is still -9.81 m/s2,

Hence,

[tex]V^2-U^2=2(-9.81)*-H[/tex]

Therefore

[tex]V_{int}=\sqrt{U^2+19.6H}[/tex]

Answer:

Displacement=10 meters

Explanation:

The displacement is the direct path from the first contact with the ball and the last spot it was seen in. The ball was kicked north 8 meters, meaning it was kicked vertically upward, and then it was kicked east 6 meters, or to the right. If we were to draw the displacement we would see that this is a right triangle. That means we can use the Pythagorean Theorem:

[tex]a^2+b^2=c^2\\8^2+6^2=c^2\\64+36=c^2\\c^2=100\\\sqrt{c} =\sqrt{100} \\c=10[/tex]

Boom.

The displacement is 10 m toward the northeast. The first option is correct.

The displacement is a vector quantity having both magnitude and direction. It is equal to the path length between the initial and final positions.

Given:

North displacement, y=8 m

East displacement, x= 6 m

The net displacement is calculated using Pythagoras' theorem as the displacements are perpendicular to each other.

The displacement is given by:

d=√(x²+y²)

d=√(8²+6²)

d=10 m

So, the displacement is 10 m.

Therefore, the displacement is 10 m toward the northeast. The first option is correct.

Answer:

22.9km

Explanation:

If the mountain is 1.00 km higher in elevation than your position and the angle measured from your position to the top of a mountain is 2.50∘.then you would have been 22.9 km far away from the mountain

A right-angled triangle's side ratios are the easiest way to express a function of an arc or angle, such as the sine, cosine, tangent, cotangent, secant, or cosecant. These functions are known as trigonometric functions.

As given in the problem you measure the angle from your position to the top of a mountain to be 2.50∘. If the mountain is 1.00 km higher in elevation than your position,

By using the tangent trigonometric function for the right triangle

tanθ = height /distance

tan 2.5° = 1000 m /distance

distance =1000 m /tan 2.5°

              =22903 m

              =22.9 km

Thus, the mountain is 22.9 km far away from your position

Answer:

Good conducters of heat and electricity. High melting points. high density. malleable. Ductile.

Explanation:

sorry,pls I don't understand

Explanation:

At first it is in 14m position but position doesn't matter in displacement, similar case for time taken.

So at first it travels 6m in positive direction.

So displacement= 6m

Then it travels 13 in opposite or negative direction.

So displacement = 6 -13 m = -7 m

Answer:

1. The weight of the column of water above

2. Due to Gravity

(I would say there are two answers for this question)

Explanation:

1.

The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions. For example, the pressure acting on a dam at the bottom of a reservoir is greater than the pressure acting near the top.

2.

Fluid pressure can be caused by gravity, acceleration, or forces in a closed container. Since a fluid has no definite shape, its pressure applies in all directions. Fluid pressure can also be amplified through hydraulic mechanisms and changes with the velocity of the fluid.

Las magnitudes vectoriales son cantidades tienen modulo y dirección, la velocidad es una de estas magnitudes, por lo tanto deben ser sumada usando álgebra vectorial.

Un sistema de referencia es un sistema desde donde realizar las mediciones, en este caso indican que usemos un sistema de los puntos cardinales.

En el adjunto podemos ver un esquema de los vectores velocidad y su resultante, realicemos el calculo de la resultante por método analíticos

Indican que el valor de la velocidad hacia el Este es vₓ = 20 m/s y la velocidad hacia el Norte es v_y = 90 m/s, por lo tanto, para la magnitud usamos el Teorema de Pitágoras

           [tex]R= \sqrt{v_x^2 + v_y^2}[/tex]

           R = [tex]\sqrt{20^2 + 90^2}[/tex]

          R = 92,2 m/s

Para encontrar la direccion usemos trigonometría

          tan θ = [tex]\frac{v_y}{v_x}[/tex]

          θ = tan⁻¹ [tex]\frac{v_y}{v_x}[/tex]

          θ = tan⁻¹ 20/90

          θ = 12,5º

La dirección se lee 12,5º al Norte del Este
