Answer:

B. Boiling point

Explanation:

Boiling water: A phase change occurs when water boils.

The three common phases are solid, liquid, and gas. A phase change happens when one phase changes into different phase without a change in chemical composition.

When water boils, the liquid phase becomes a gas (water vapor or steam). The chemical composition of water does not change while boiling because each phase consists of water.

Thus, boiling water is the phenomena of a phase change.

Therefore there will be a phase change at boiling point.

A ceiling fan is turned on and reaches an angular speed of 132 rev/min in 20 s. It is then turned off and coasts to a stop in an
Mkey [24]

Answer:

Explanation:

α = (ωf - ωi)/t

acceleration phase

ωf = 132 rev/min (2π rad/rev / 60 s/min) = 4.4π rad/s

α₁ = (4.4π - 0)/20 = 0.22π rad/s²

α₂ = (0 - 4.4π)/40 = - 0.11π rad/s²

α₁/α₂ = 0.22π/- 0.11π = -2

A exercise ball is on a table 2.5 m above the ground. What is the mass
horsena [70]

Answer:

2.27kg

Explanation:

The Potential energy gained = Force gravity× Height

Force gravity on the ball is GPE/ height

56.8/2.5=22.72N

the mass = 22.72/10= 2.27kg

You are watching an archery tournament when you start wondering how fast an arrow is shot from the bow. Remembering your physics
valentina_108 [34]

Answer:

v = 69.82 ms^-1

Explanation:

As we know,

R = vi2 sin2Ꝋ / g  

vi2 =R g / sin2 Ꝋ where R is range R = 52m, Ꝋ = 3 Degrees

vi2 = 52 x 9.8 / sin 2(3) = 4875.227

v = 69.82 ms^-1
