Answer:
3.78 m on the left side of the seesaw
Explanation:
The net torque in this situation is zero, so the torque from each side of the pivot point must balance each other out:
(50.0 kg x 10.0 m/s^2)(3.4m) = (450 N) r
Solve for r, and you get 3.78 on the left side.
Hope this helps!
Answer:
The resistivity is ![\rho = 2.5 *10^{-8} \ \Omega \cdot m](https://tex.z-dn.net/?f=%5Crho%20%20%3D%20%202.5%20%2A10%5E%7B-8%7D%20%5C%20%20%5COmega%20%5Ccdot%20m)
Explanation:
From the question we are told that
The magnitude of the electric field is ![E = 6.2 V/m](https://tex.z-dn.net/?f=E%20%3D%20%206.2%20V%2Fm)
The current density is ![J = 2.4 *10^{8} \ A/m^2](https://tex.z-dn.net/?f=J%20%20%3D%20%202.4%20%2A10%5E%7B8%7D%20%5C%20%20A%2Fm%5E2)
Generally the resistivity is mathematically represented as
![\rho = \frac{E}{J}](https://tex.z-dn.net/?f=%5Crho%20%20%3D%20%20%5Cfrac%7BE%7D%7BJ%7D)
substituting values
![\rho = \frac{6.2}{2.4 *10^{8}}](https://tex.z-dn.net/?f=%5Crho%20%20%3D%20%20%5Cfrac%7B6.2%7D%7B2.4%20%2A10%5E%7B8%7D%7D)
![\rho = 2.5 *10^{-8} \ \Omega \cdot m](https://tex.z-dn.net/?f=%5Crho%20%20%3D%20%202.5%20%2A10%5E%7B-8%7D%20%5C%20%20%5COmega%20%5Ccdot%20m)
Impulse equals Change in Momentum
F = average applied force = to be determined
Δt = time during which the force is applied = 0.50 s
m = mass = 1,700 kg
Δp = change in momentum = to be determined
Δv = change in velocity = to be determined
v1 = initial velocity = 50.0 km/h = 50,000 m/h = 13.9 m/s
v2 = final velocity = 0.00 km/h = 0.00 m/s
F∙Δt = Δp
F∙Δt = m∙Δv
F∙Δt = m∙(v2 - v1)
F = m∙(v2 - v1) / Δt
F = 1,700 kg∙(0.00 m/s - 13.9 m/s) / 0.50 s

Answer: The acceleration of 28 Kg object will be 2 ![m/s^{2}](https://tex.z-dn.net/?f=m%2Fs%5E%7B2%7D)
Explanation: Force acting on an object is defined as mass times acceleration acting on it.
Mathematically it is defined as:
Force = mass
acceleration
F = 8
7 = 56 N
If the same force is acting on a 28 Kg object then the acceleration of the object will be equals to force to mass ratio.
Acceleration =
= 2 ![m/s^{2}](https://tex.z-dn.net/?f=m%2Fs%5E%7B2%7D)
