Answer:

As we know that, 

1 mm/min = 1.66667E-5 m/s
1 m/s = 60000 mm/min

Now, come to the question - 

$\\ \implies \sf \: 2536 \times 1.66667E-5 m/s \\ \\ \\ \implies \sf \blue{0.0422666667 \:m/s } \\$

Result : 2536 mm/min = 0.0422666667 m/s.

Which of the following terms best describes the scenario below? A meteor moving through outer space continues to move on the sam

klasskru [66]

Answer:

Option B. inertia

Explanation:

Inertia can be explained as the property of a body due to which the body resists any change in its form or shape.

The given case complies with Newton's first law or Law of inertia which says_ a body in motion will remain in that state of motion or at rest will continue to be in that stationary until it comes under the action of some external force.

Therefore, a meteor moving through outer space will continue on that path until acted upon by an external force.

A test rocket is launched vertically from ground level (y = 0 m), at time t = 0.0 s. The rocket engine provides constant upward

Romashka-Z-Leto [24]

The rocket starts at rest, so its initial velocity is 0. If the burn phase lasts $t$ seconds, then during this interval the rocket's velocity is

$v=at\implies a=\dfrac{30\,\frac{\mathrm m}{\mathrm s}}t$

and its position is

$x=\dfrac12at^2\implies a=\dfrac{2(49\,\mathrm m)}{t^2}$

So we have

$\dfrac{30\,\frac{\mathrm m}{\mathrm s}}t=\dfrac{2(49\,\mathrm m)}{t^2}\implies t=3.3\,\mathrm s$

and the answer is C.

An electric oven has a resistance of 201 ohms and a voltage of 220 V. How much current does it draw?

asambeis [7]

1.1 A. An electric oven with a resistance of 201Ω and a voltage of 220V drwa a current of 1.1 A.

The easiest way to solve this problem is using the Ohm's Law I = V/R.

An electric oven has R = 201Ω, and a drop of voltage V = 220v, solve using I = V/R:

I = 220V / 201Ω

I = 1.09 A ≅ 1.1 A
