Answer:
speed and acceleration
Explanation:
speed is a scalar quantity
acceleration is a vector quantity
Answer:
Acceleration will be equal to
Explanation:
We have given mass of the object m = 0.4 kg
Spring constant k = 8 N/m
Maximum displacement of the spring is given x = 0.1 m
From newton's law force is equal to
.....eqn 1
By hook's law spring force is equal to
.....eqn 2
From equation 1 and equation 2
![ma=kx](https://tex.z-dn.net/?f=ma%3Dkx)
![0.4\times a=8\times 0.1](https://tex.z-dn.net/?f=0.4%5Ctimes%20a%3D8%5Ctimes%200.1)
![a=2m/sec^2](https://tex.z-dn.net/?f=a%3D2m%2Fsec%5E2)
So acceleration will be equal to ![2m/sec^2](https://tex.z-dn.net/?f=2m%2Fsec%5E2)
Iron is the solvent and carbon is the solute.
Answer: 168.75 N
Explanation:
first, let's convert microcoulombs to coulombs
q1 = 1e-4 C
q2 = 3e-5 C
r = 0.4 m
then use the equation Fe = ![\frac{kq_{1} q_{2}}{r^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7Bkq_%7B1%7D%20q_%7B2%7D%7D%7Br%5E%7B2%7D%20%7D)
plug in values --> F = (9e9*1e-4*3e-5)/(0.4)^2
F = 168.75 N
Because solo gold isn't strong material. But with admixture it's stronger.
