Answer:

New time period, T_2=2.12\ s

Explanation:

Given that,

Mass of the object 1, m_1=0.75\ kg

Time period, T_1=1.5\ s

If object 1 is replaced by object 2, m_2=1.5\ kg

Let T_2 is the new period of oscillation.

The time period of oscillation of mass 1 is given by :

T_1=2\pi \sqrt{\dfrac{m_1}{k}}

1.5=2\pi \sqrt{\dfrac{0.75}{k}}............(1)

The time period of oscillation of mass 2 is given by :

T_2=2\pi \sqrt{\dfrac{m_2}{k}}

T_2=2\pi \sqrt{\dfrac{1.5}{k}}............(2)

From equation (1) and (2) we get :

(\dfrac{T_1}{T_2})^2=\dfrac{m_1}{m_2}

(\dfrac{1.5}{T_2})^2=\dfrac{0.75}{1.5}

\dfrac{1.5}{T_2}=0.707

T_2=2.12\ s

So, the new period of oscillation is 2.12 seconds. Hence, this is the required solution.

A force acts on a 5kg object at rest. How fast will the object accelerate on a frictionless surface?
MakcuM [25]

Answer: The answer is C.) 25 m/s^2.

Explanation: If you input 5 as s, you would have to use the exponent 2.  This means that you have to multiply 5 by 5.  5 x 5= 25.  

Edit: Also, because the surface is frictionless, it will make the object go faster too.  Nothing can really slow it down unless something blocks it.

What is the difference between a mineral and a rock
Sedbober [7]

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes.

A rock is an aggregate of one or more minerals. It may also contain organic remains and mineraloids apart from regular mineral formations. Since rocks vary in their mineral and chemical composition, they are classified according to the process of their formation.

On your first trip to Planet X you happen to take along a 280 g mass, a 40-cm-long spring, a meter stick, and a stopwatch. You'r
arsen [322]

Answer:

5.31143691523 m/s²

Explanation:

m = Mass = 280 g

x = Displacement of spring = 21.7 cm

Time period

T=\dfrac{14}{11}\\\Rightarrow T=1.27\ s

Angular velocity is given by

\omega=\dfrac{2\pi}{T}\\\Rightarrow \omega=\dfrac{2\pi}{1.27}\\\Rightarrow \omega=4.94739\ rad/s

\omega=\sqrt{\dfrac{k}{m}}\\\Rightarrow k=\omega^2m\\\Rightarrow k=4.94739^2\times 0.28\\\Rightarrow k=6.85346698739\ N/m

From Hooke's law

mg=kx\\\Rightarrow g=\dfrac{kx}{m}\\\Rightarrow g=\dfrac{6.85346698739\times 0.217}{0.28}\\\Rightarrow g=5.31143691523\ m/s^2

The acceleration due to gravity on the planet is 5.31143691523 m/s²

Yes, I have been able to satisfy my curiosity.
