Answer:
film is at distance of 3.07 cm from lens
Explanation:
Given data
focal length = 3.06 cm
distance = 10.4 m = 1040 cm
to find out
How far must the lens
solution
we apply here lens formula that is
1/f = 1/p + 1/q
here f = 3.06 and p = 1040 so we find q
1/f = 1/p + 1/q
1/3.06 = 1/1040 + 1/q
1/ q = 0.3258
q = 3.0690 cm
so film is at distance of 3.07 cm from lens
The definition for nebula is : A cloud of gas and dust in outer space, visible in the night sky either as an indistinct bright patch or as a dark silhouette against other luminous matter.
Answer
given,
mass skateboard = 5 Kg
length on the horizontal road = 2 m
maximum speed she can run= 8 m/s
mass of girl = 50 Kg
conservation of momentum
M V = (M+m)v
50 x 8 = (50 + 5)v
400 = (55)v
v = 7.27 m/s
using conservation of momentum
h = 2.69 m
no, she will not be able to reach the height of 3 m
Answer:
The process of making alloys involves ( Heating ) pure metals to remove impurities. Then the pure metals are(mixed) with other components. An alloy is a mixture of metals or a mixture of a metal and another element. Alloys are defined by a metallic bonding character.
