deff fn [24]3 years ago

Answer:

The correct option is;

Absolute zero

Explanation:

A Bose-Einstein condensate is known as the fifth state of matter which is made of a collection of ultra cooled atoms (at almost absolute zero degrees -273.15 °C) such that the there is very slight free energy within the atoms which results in almost no relative motion between the atoms. The atoms then combine forming clumps such that phenomena usually observed at the microscopic level such as wavefunction interference become observable at the microscopic level.

A small 32-kilogram canoe broke free of its dock and is now floating downriver at a speed of 2.5 m/s. What is
marysya [2.9K]
<h3>Answer:</h3>

80 kgm/s

<h3>Explanation:</h3>

<u>We are given;</u>

  • Mass of the Canoe is 32 kg
  • Speed of the Canoe is 2.5 m/s

We are required to calculate the momentum of the Canoe?

  • We need to know that momentum is the product of mass of an object and its speed.
  • Therefore;

Momentum = Mass × speed

Therefore;

Momentum = 32 kg × 2.5 m/s

                   = 80 Kgm/s

Thus, the momentum of the Canoe is 80 kgm/s.

A 56.0 kg box hangs from a rope. what is the tension in the rope if: the box has vy = 5.30 m/s and is speeding up at 5.10 m/s2 ?
Minchanka [31]

T = tension force in the rope in upward direction

m = mass of the box attached at end of rope = 56 kg

W = weight of the box in downward direction due to gravity

a = acceleration of the box in upward direction = 5.10 m/s²

weight of the box is given as

W = mg

inserting the values

W = (56) (9.8)

W = 548.8 N


force equation for the motion of the box is given as

T - W = ma

inserting the values

T - 548.8 = (56) (5.10)

T = 834.4 N

What happens to the force between the spheres when you increase the mass of one of the spheres?
andrew11 [14]

The force between the spheres increases when the mass increases in one of the spheres.

<u>Explanation:</u>

            Newton law of universal gravity extends gravity beyond the earth's surface. This gravity depends directly on the mass of both objects and is inversely proportional to square of distance between their centers.  

                   \bold{F=\frac{G \times\left(m_{1} \times m_{2}\right)}{\left(r^{2}\right)}}

          Since gravity is directly proportional to “mass of both interacting objects”, stronger objects with greater gravitational force attract. If the mass of one object increases, gravity between them also increases. For example, if an object's mass of one double, force between them also doubles.
