The period is √2 *T if the mass is doubled to 2m.
What is the time period?
The time period is the length of time during which an activity occurs or a condition remains.
The equation for the period T is given as:
where k is the spring constant
mass of the system = m
Here,
If the mass id doubled to 2m for the system that is set in motion,
new mass is now 2m
So the equation for time period becomes,
Hence,
The period is √2 *T if the mass is doubled to 2m.

Answer:
the answers are c and d
Explanation:
a marble does not move like a atom and is not small enough
Answer:
(a) 
(b) 157.76679 m
(c) 17.62757 m/s
Explanation:
Net force acting, 
Acceleration, 
where m is the mass
(b)
From kinematic equation
where s is displacement, u is initial velocity, t is time taken and a is acceleration.
Considering that u=0 since it starts at rest
and substituting the value of a as calculated in part a, t is 17.9 s hence
(c
)
From kinematic equation
v=u+at where u and v are initial and final velocities respectively, a is acceleration and t is duration in seconds. Since it starts from rest, u=0 and substituting the value of a as found in part a, t given as 17.9 s we get
V=0+0.984781*17.9=17.62757 m/s
Answer:
Earl needs to touch the pan to the burner.
Explanation:
Earl is demonstrating heat transfer by conduction.
Conduction is the transition of heat energy by direct contact. Hotter molecules have more momentum and they move faster.These hot molecules collide with the cooler ones, transfer their energy to cooler particles , this process is continued to pass it on to other molecule near to them.
Earl needs to touch the pan to the burner.
