Answer:
Fr = 150 [N]
a = 5 [m/s²]
Explanation:
In order to find the resulting force, we must assume that the thrust force is positive to the right, while the friction force is negative to the left.
![F_{r}=200-50\\F_{r}=150[N]](https://tex.z-dn.net/?f=F_%7Br%7D%3D200-50%5C%5CF_%7Br%7D%3D150%5BN%5D)
Now Newton's Second Law tells us that the sum of the forces or the resulting force is equal to the product of mass by acceleration.
F = m*a
![150 = 30*a\\a=150/30\\a = 5 [m/s^{2} ]](https://tex.z-dn.net/?f=150%20%3D%2030%2Aa%5C%5Ca%3D150%2F30%5C%5Ca%20%3D%205%20%5Bm%2Fs%5E%7B2%7D%20%5D)
Answer:
A: Conduction
B: Convection
C: Radiation
Explanation:
Conduction is the transfer of heat in internal energy by microscopic collisions of particles and movement of electrons within a body so from the fire hitting the metal. Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids so the water boiling in the pot. Radiation is the handle heating up due to the heat interacting with it.
I would say the the answer is 7.20 because if subtract the 8.00 grams from the 15.20 g you would get 7.20. Am I correct, please ley me know
Answer:
θ = 66.90°
Explanation:
we know that

I= intensity of polarized light =1
I_o= intensity of unpolarized light = 13
putting vales we get

⇒
therefore θ = 66.90°
