Given,
Effort force = 120 N
Load force= 1050 N
Mechanical advantage of a pulley is given by the ratio of load force to the effort force.
Therefore, the mechanical advantage of the given pulley is 8.75.
Answer:
600 J
Explanation:
it's obviously btw so yeahhhh
The angular frequency of the wave is determined as 75.4 rad/s.
<h3>
What is wave function?</h3>
A wave function is a mathematical equation for the motion of the wave.
y(x, t) = A sin(kx + ωt + Φ)
where;
- ω is angular speed
- k is angular wavenumber
- Φ is phase angle
<h3>What is angular frequency?</h3>
The angular frequency is the angular displacement of any wave element per unit of time or the rate of change of the waveform phase.
<h3>Angular frequency</h3>
ω = 2πf
ω = 2π(12)
ω = 75.4 rad/s
Thus, the angular frequency of the wave is determined as 75.4 rad/s.

Answer:
Explanation:
Given
mass of automobile
velocity of automobile
If the automobile crashes into the brick wall then it's kinetic energy is converted into thermal and demolishing energy to wall.
Car completely stops as it crashes into the wall so Energy converted into demolition and thermal energy
KE = 1/2 mv^2
in this case, the initial kinetic energy which is converted to heat is
KE = 1/2 1400 (12)^2
KE = 100,800 J
