Acceleration =
(change in speed) / (time for the change)
and the direction of the change.
Acceleration = (60 - 0) km per hour / 5 sec = <em>12 km per hour per second, east</em>.
I hear teachers all over the country complaining about that ugly unit.
It has to be changed to a more familiar unit of acceleration.
(12 km/hour) x (1 hour/3600sec) = 12,000/3600 = 3-1/3 meter/sec.
His acceleration is <em>3-1/3 meters per second²</em> .
A superheated cloud of gas and dust swirling around a massive object (usually a black hole or neutron star) is called an accretion disk. The correct option is c.
<h3>What is accretion disk?</h3>
Accretion disk is a heavy object surrounded by flow of gas, plasma, dust, or particles. The materials surrounding the heavy object orbiting in the gravitational field of the object that loses energy and angular momentum as it slowly spirals inward.
This cloud can reach incredible speeds and temperatures as gravity causes it to build up more and more friction, eventually releasing x rays.
Thus, accretion disk is a superheated cloud of gas and dust swirling around a massive object.

Answer:
I would have to go with A, or maybe....yea A
Answer:
living being is the being which have charcterstics like reproduction movement etc
Explanation:
plz give me brainliest
net force= the sum of all the forces acting on the object
the frictional force is opposite to the direction of motion of the object
If the object moves to the right (positive) then the friction force moves to the left (negative).
so the net force: 50 N - 5 N = 45 N (B)
