The characteristic of life would be homeostasis. Homeostasis regulates the variables in which internal conditions remain stable and consistent. This type of regulation is the regulation of temperature and the balance between acidity and alkalinity, also known as pH. Hope this helps! :)
What is the work done in stretching a spring by a distance of 0.5m if the restoring force is 48N is 12 J.
Hooke's Law states that the more you deform a spring, the more force it will take to deform it further.
Notations: F= Restoring force
k= spring constant
x = spring displacement
Given: F = 48N,
x= 0.5m
By using Formula; F= kx
F = 48 = kx, k = F/x
k = 48/0.5 = 96 N/m
work done by spring = 1/2 (kx)² = 1/2(96x0.5)² = 12 J
work done by spring is 12J.

Answer:
1.The temperature of each sample will increase by the same amount
Explanation:
This is because, since their specific heat capacities are the same and we have the same mass of each substance, and the same amount of energy due to heat flow is supplied to both the glass and brick at room temperature, their temperatures would thereby increase by the same amount.
This is shown by the calculation below
Q = mcΔT
ΔT = Q/mc where ΔT = temperature change, Q = amount of heat, m = mass of substance and c = specific heat capacity of substance.
Since Q, m and c are the same for both substances, thus ΔT will be the same.
So, the temperature of each sample will increase by the same amount
20,000,000 kg*m/s
p=mv
10,000,000=m(v/2)
20,000,000=mv
