The New Horizons probe flew past Pluto in July 2015. At the time, Pluto was about 32 AU from Earth. How long did it take for com

Answer:

15944.6 sec

Explanation:

d = distance of Pluto from earth = 32 AU = 32 x 1.496 x 10¹¹ m

v = speed of light = 1.08 x 10⁹ km/hr = ( 1.08 x 10⁹) (0.278) m/s

t = time taken for the communication to reach from probe to earth = ?

Using the equation

d = v t

Inserting the values given

32 x 1.496 x 10¹¹ = (( 1.08 x 10⁹) (0.278)) t

t = 15944.6 sec

t = 1.6 x 10⁴ sec

The tangential acceleration of a cart moving at a constant speed in a horizontal circle is:
qaws [65]

Answer:

a=0                                  ∵ \alpha=0\ rad.s^{-1}

Explanation:

The tangential acceleration of a cart moving at a constant speed in a circle is:

The angular velocity is constant when the circular speed is constant.

We know that the (instantaneous) tangential velocity of such object is given by:

v=r.\omega

Now for angular acceleration we have a constant angular speed:

\alpha=0\ rad.s^{-1}

And angular acceleration is related to tangential acceleration as:

a=r.\alpha

\Rightarrow a=0

Whitepunk [10]

Answer:

6.93 km/h

Explanation:

To calculate her average speed, we need the "speed" formula, which is:

average speed = distance / time

You plug in your numbers and it will give you the answer.

Speed = 4.5km/0.65hr

           = 6.923 km/h

If a metal ball suspended by a rod is at rest, which force is responsible for balancing the force due to gravity?
Viktor [21]

There are different kinds of forces; applied force, force of gravity, friction force, normal force, tension force. We will focus on the common forces, applied force and force of gravity. An applied force is a force that is applied to an object by another object. The force of gravity is the force with which massively large objects such as the earth attracts another object towards itself. All objects of the earth exert a gravity that is directed towards the center of the earth. Therefore, the force of gravity of the earth is equal to the weight of the object.
