If a 500 kg load is to be lifted with a 100N effort using a first class lever at what distance from the fulcrum must the effort be aaplied when the load is 20cm away from the fulcrum​

Explanation:

Hey there!

According to the question;

Load (l) = 500 kg

Effort (e) = 100 N

Load distance (ld) = 20cm

Effort distance (ed) = ?

According to the principal of lever;

L*LD = E*ED

500*20 = 100*ED

ED = (500*20)/100

Therefore, the Effort must be applied at 100 cm.

Hope it helps!

breathe deeply from your lower lungs - imagine a rubber ring around your waist (your diaphragm)

breathe in and try to push the ring outwards.

breathe in through your nose and out through your nose and mouth.

how to know you're in love with someone you've just started getting to know can be a bit tricky because — feelings aside — they are technically still a stranger to you. although you might feel the urge to dive in and start professing your undying love for them asap, it's important to remember that it can be easy to confuse feelings of immense attraction with actual love.
