A.
Pressure = force/area
SI units for force = newtons
SI units for area = square meters
So pressure = n/m^2
Ikr!! I asked 1 question 3x and wasted my points to get some link?!
I think it is electron. Electrons are located outside of the nucleus
Answer:
for air focus is 12 cm
when immersed in water focus is 39 c.m
Explanation:
we know lens maker formula
so for air n=1 and n2=1.5
now putting the value in lens maker formula now [/tex][/tex]
when lens is immersed in water then n1=1.3 and n2=1.5
putting the value in lens maker formula
now [/tex]
Answer:
6.03 m/s
Explanation:
<em>Average speed = total distance traveled/total time taken</em>
7 = 450 + 100/total time
total time = 550/7 = 78.57 s
<em>Speed of camel on the bicycle = distance/time</em>
25 = 100/time
time = 100/25 = 4 s
Total time = 78.57 s
Time spent riding bicycle = 4 s
<em>Time spent walking = total time - time spent riding bicycle</em>
= 78.57 - 4 = 74.57 s
<em>Speed of walking = distance walked/time spent walking</em>
= 450/74.57
= 6.03 m/s
