The correct answer is option B. i.e. 60 ohm.
The diagram is attached.
Since all the resistances are attached in series.
Hence, the total resistance will be the sum of all resistances.
R_total = R_1+R_2+ R_3
= 10+20+30
= 60 ohms.
Therefore, option c is correct answer.
To solve this problem we will apply the two concepts mentioned. To find the constant we will apply Hooke's law, and to find the period we will apply the relationship between the mass and the spring constant. Let us begin,
PART A) For this section we will use Hooke's law. In turn, since the force applied is equivalent to weight, we will use Newton's law for which weight is defined as the product between mass and gravity. This weight is equal to the Spring Force.
Here,
k = Spring constant
= Displacement
F = Force, the same as the Weight (mg)
Then we have that
Therefore the spring constant is 13.23N/m
PART B) To find the period of oscillation, the relationship that allows us to find is given by the following mathematical function,
Here
m = mass
k = Spring constant
Replacing,
Therefore the period of the oscillation is 0.491s

plz mark brainliest again lol :)
Explanation:
When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.
Answer:
You have to divide your real measurement to the model. For example, if your real measurement is 5m and your model is 20cm, divide 5/20 =1/4 and that means the ratio would be 1:4.
Explanation:
Answer: Open system
According to thermodynamics, if a system exchanges matter and energy with its environment it is an open system. For example, human beings and animals can be considered as open systems, since we take chemical energy in the form of food and perform work on our surrounding environment when moving and doing activities.
