Answer:

1\; \rm V.

Explanation:

Ohm's Law give the following relationship between the potential V across a conductor, the electrical resistance R of that conductor, and the current I through that conductor:

V = I \, R.

It is given that the current through this conductor is I = 1\; {\rm A}, and that the electrical resistance of this conductor is R = 1\; \rm \Omega.

Note, that the unit of electrical resistance Ohm is a composite unit; 1\; {\rm \Omega} = 1\; {\rm V \cdot A^{-1}} (volts per ampere.)

Substitute the value of I and R into the equation V = I \, R from Ohm's Law to find the potential across this conductor:

\begin{aligned}V &= I \, R \\ &= 1\; {\rm A} \times 1\; {\rm \Omega} \\ &= 1\; {\rm A} \times 1\; {\rm V \cdot A^{-1}} \\ &= 1\; {\rm V}\end{aligned}.

Why is the escape speed for a spacecraft independent of the spacecraft's mass?
scoray [572]
In order to escape the gravitational pull of our planet, any object must have an escape velocity of 7 km/s  or more, anything lower than that will be slowed down by the pull of gravity, and will eventually returned to the surface of our planet. It is independent of mass, any lighter or heavier object must attain the required escaped velocity to reach space.

Here on Earth you hang a mass from a vertical spring and start it oscillating with amplitude 1.9 cm. You observe that it takes 3
Vlada [557]

Answer:

T = 3.23 s

Explanation:

In the simple harmonic movement of a spring with a mass the angular velocity is given by

               w = √ K / m

With the initial data let's look for the ratio k / m

The angular velocity is related to the frequency and period

           w = 2π f = 2π / T

            2π / T = √ k / m

            k₀ / m₀ = (2π / T)²

            k₀ / m₀ = (2π / 3.0)²

            k₀ / m₀ = 4.3865

The period on the new planet is

          2π / T = √ k / m

           T = 2π √ m / k

In this case the amounts are

           m = 6 m₀

           k = 10 k₀

We replace

            T = 2π√6m₀ / 10k₀

            T = 2π √6/10 √m₀ / k₀

            T = 2π √ 0.6  √1 / 4.3865

            T = 3.23 s

A real spring does not oscillate forever. Instead, it eventually comes to a stop. Does this violate the law of conservation of e
ss7ja [257]
It does not violate the law of conservation of energy. The oscillation stops when the energy is lost and the energy is lost because it becomes heat that is created by the air resistance and many other forces found in the surrounding of the oscillating spring.
