Answer:
so his far point according to this pair of glass is 200 cm
Explanation:
power of old pair of corrective glasses is given as
now we have
now we know that for normal vision the maximum distance of vision is for infinite distance
so by lens formula we have
so his far point according to this pair of glass is 200 cm
Explicacion
m = 65 kg
g = 10 m/s²
r = 0.5 cm (1m / 100 cm) = 0.05 m
A = π r² = π (0.05 m)² = 0.00785 m²
F =W = m g = 65 kg(10 m/s²) = 650 N
P = F/A = 650 N / 0.00785 m² = 82802.54 N/m²
Answer:
7.8
Explanation:
Here, an effort of 50 N is applied at the car key and overcomes the resistance(or load) of 390 N at the lid.
mechanical advantage
=load/effort
=390 N/50 N
=7.8
Answer:
1 3/5*2/3=6/15
2 (3/5*2/3)+(2/3*5/6)+(3/5*5/6)=Ans
3 same as 2 i think
4 3/5+2/3+5/6=ans
5 (1-3/5)*(1-2/3)*(1-5/6)
Explanation
1 means x and y... for such a we multiply the probabilities
2 means x and y or x and z or y and z9 multiply ands add ors
3 i think it is same as 2
4 for this you have to negate the probabilities of killing to find that of not killing. Since it will be x and y and z, you multiply the final probabilities
