Answer:
A
Explanation:
We know the force is (16N-12), which is 4N, and we know the acceleration is 2 m/s^2. Meaning, we can solve the formula m = F / a (mass equals force divided by acceleration), and we get 2kg.
Answer:
b
Explanation:
I've been in a couple of bad relationships and I can say by experience that it is very stressful.
Answer:
Pressure
Explanation:
The measure of how much force is applied to an object from gas particle bouncing into it is called pressure.
Pressure is defined as the force per unit area on a body.
Mathematically;
Pressure = 
The pressure of a gas is the combined force with which gas molecules bombard a unit area of the wall of the container. It is the sum of all tiny pushes on the wall of the container.
Various units of pressure are atm, mmHg, torr, pascal e.t.c
A. Acceleration that’s the answer I think so
Answer:
4.3 N/m
Explanation:
m = 230 g = 0.230 kg, x = 8.2 cm
in 13 oscillations, time taken = 19 s
In 1 oscillation, time taken = 19 / 13 = 1.46 s
By the use of formula of time period , Let k be the spring constant.


0.054 = 0.230 / k
k = 4.26 N/m
k = 4.3 N/m
