Mass of cyclist = 100 kg

Mass of gorilla = 50 kg

Initial speed = 4.5 m/s

Let Final speed = s

100 x 4.5 = (100 + 50) x s

450 = 150s

S = 450/150

S = 3

The new speed is 3m/s

Answer:A, you would weigh the same on both planets because their masses and the distance to their centers of gravity are the same

Explanation:

**Answer:**

m

**Explanation:**

Consider the motion of the stone in vertical direction:

= initial velocity = 0 m/s

= acceleration due to gravity = 9.8 m/s²

= time taken to hit the water below

= vertical height of the cliff

Using the kinematics equation

eq-1

consider the motion of sound from water in upward direction

= Speed of sound = 343 m/s

= time of travel for sound

Using the equation

eq-2

we have been given that

Using eq-1 and eq-2

m

When osmium goes from a **solid **to a **liquid **and finally a **gas**, the element has undergone <u>**phase changes**</u>

<u></u>

The osmium is a **transition chemical element **which is also known as "Os" in the periodic table. Its atomic number is 76. It is **hard**, brittle, bluish metal at **room temperature**, but it can be **liquid **when it heats up until its **melting point **(3000°C) and if it keeps heating it can finally be a **gas **when it reaches its **boiling point **(5500°C).

<h3>What are the phase change materials?</h3>

The **phase change materials**, also known as **PCMs**, are the **elements **able to absorb, store and release large **amounts **of **heat **over a defined temperature range when the **element changes phase **or state.

**Answer:**

** 62.64 RPM.**

**Explanation:**

Given that

m= 4.6 g

r= 19 cm

μs = 0.820

μk = 0.440.

The angular speed of the turntable = ω rad/s

Condition just before the slipping starts

The maximum value of the static friction force =Centripetal force

Therefore the speed in RPM will be** 62.64 RPM.**
