Answer:
Explanation:
The balance condition, to keep the gate from moving, requires that the net torque be zero, this is, the torques on both sides of the gate must be equal.
- Torque equation: τ = F × d
a) <u>Torque applied by one of the children:</u>
b) <u>Torque applied by the second child</u>:
c) <u>Equilibrium condition</u>:
- τ₁ = τ₂
- 170 N × 0.590m = F × 0.430m
- F = 170 N × 0.590 m / 0.430 m = 233 N ← answer
Answer:
u = 44.44 m/s
Explanation:
given,
horizontal displacement = 50 m
maximum height = 100 m
initial velocity (v₀) = ?
launching angle(θ) = ?
using formula
........(1)
.........(2)
dividing equation (2)/(1)
now using equation (2)
u = 44.44 m/s
Options: A. Tech A. B. Tech B. C. Tech And B. C. None of the above.
Answer:Tech A and B
Explanation:A shift lever is the lever installed on the steering column or floor of a vehicle which allows the driver to shift gears or change gears, the manual valve position is controlled by shift lever as the shift lever moves the manual valve position changes. The
Ball Plungers are self-contained ball-and-spring devices,used in rolling and detent applications, they are used to position the manual valve in a vehicle.
I got no earthly idea! Sorry........
Answer:
e) A changing magnetic field produces an electric field.
Explanation:
Ok, we start with a magnetic field and let's study how it affects the motion of a single electron. As the magnetic field changes, it will cause an electromotive force, that moves the electron, and because now we have a moving electron, now we will have an electric field. (Such that the direction of the electromotive force opposes the direction in which the magnetic field changes). This also can be deduced if we look at the third Maxwell's equation:
dE/dx = -dB/dt
This says that the spatial change in an electric field depends on how the magnetic field changes as time pass.
Then the correct option is e) A changing magnetic field produces an electric field.
