Answer:
A body is said to be moving with uniform speed, if it covers equal distances in equal intervals of time. ...
The answer is 30 ... same as the Atomic number.
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
The collision between two objects is an example of a contact force
Explanation:
average speed = total distance ÷ total time taken
=30÷2 = 15 km/h
