Answer:
Explanation:
Using Pascal laws, which states that pressure are the input equals the pressure at the output.
Pressure is given as force/area
P1=P2
Then,
F1/A1=F2/A2
Cross multiply
F1A2=F2A1
Given that
Ae=0.5m² area of effort
Al=5m² area of load
Fl=? Force if load
Fe= 100N. Force of effort
Then applying pascal
Fl/Al=Fe/Ae
Fl/5=100/0.5
FL/5=200
Fl=200×5
Fl=1000N
The first safety load is 1000N
Answer: The metal with a volume is zinc.
Explanation: Got it right on Edge2020
The reason the efficiency is always less than 100% is because there is always some sort of friction in the machine.
Answer: because of friction
By definition <span>Projectile motion is a form of motion in which an object or particle i.e. called a projectile is thrown near the Earth's surface, and it moves along a curved path under the action of gravity only</span>
Answer:
Maximum acceleration will be
Explanation:
It is given mass m =40 gram = 0.04 kg
Length of the wire l = 4 m
Frequency of transverse wave f = 860 Hz
Wavelength 
Amplitude of the propagating wave 
Angular frequency is equal to 
Maximum acceleration is equal to 
So maximum acceleration will be
