A ship maneuvers to within 2500 m of an island's 1800 m high mountain peak and fires a projectile at an enemy ship 610 m on the

Answer:

option D.

Explanation:

The correct choice is option D.

For an object in equilibrium, the torque measured at any point will be zero.

An object is deemed to be in equilibrium when the net moment acting on it equals zero.

If the object experiences a net moment not equal to zero, it will rotate and will not remain stable.

<span>Details: Initial velocity, Vi = 1.20 m/s, acceleration, a = 0.31 m/s², distance, Δx = 0.75 m, final velocity, Vf =?

To find Vf, we use the formula: Vf = sqrt (Vi^2 + 2aΔx) = sqrt ((1.20 m/s)^2 + 2(0.31 m/s² * 0.75 m))
= 0.99 m/s</span>

Answer:

The electron's velocity in the x direction is measured at 57.9 m/s

Explanation:

The uncertainty in the x position of the electron is Δx = 0.200 mm = 0.2 x 10⁻³ m

Let vₓ denote the x component of the electron's velocity.

The momentum's uncertainty in the x component is given by:

Δpₓ = mΔvₓ

where m represents the electron's mass.

The uncertainty in the velocity's x component is set at 1%, or 0.01.

Thus, we can rewrite the previous equation as:

Δpₓ = 0.01mvₓ....(1)

The fundamental principle of uncertainty is:

....(2)

Using equations (1) and (2),

Substituting 0.2 x 10⁻³ m for Δx, 9.1 x 10⁻³¹ kg for m, and 6.626 x 10⁻³⁴ m²kg/s into the formula yields:

vₓ = 57.9 m/s
