'Universe' means 'Everything'. That is, all matter, all space, all time.
Answer: The spring constant is K=392.4N/m
Explanation:
According to hook's law the applied force F will be directly proportional to the extension e produced provided the spring is not distorted
The force F=ke
Where k=spring constant
e= Extention produced
h=2m
Given that
e=20cm to meter 20/100= 0.2m
m=100g to kg m=100/1000= 0.1kg
But F=mg
Ignoring air resistance
assuming g=9.81m/s²
Since the compression causes the plastic ball to poses potential energy hence energy stored in the spring
E=1/2ke²=mgh
Substituting our values to find k
First we make k subject of formula
k=2mgh/e²
k=2*0.1*9.81*2/0.1²
K=3.921/0.01
K=392.4N/m
Answer:
Integrated circuit (IC)
Explanation:
An integrated circuit ( IC ) is a semiconductor which contains multiple electronic components
interconnected to form a complete electronic function. Integrated circuits are the most essential part of all electronic products.
Modern integrated circuits contain as much as billions of circuit components such as transistors , diodes , resistors , and capacitors
onto a single monolithic die .
The correct answer would be the first option. Based on the given description above, the type of radiation that is being emitted is ALPHA RADIATION. Alpha radiation is the type of radiation having the lowest penetrative power. Take note that <span>Gamma is stronger than Beta is stronger than Alpha. Hope this answer helps. Have a great day!</span>
