Answer:
82.4 cm
Explanation:
The object and screen are kept fixed ie the distance between them is fixed and by displacing lens between them images are formed on the screen . In the first case let u be the object distance and v be the image distance
then ,
u + v = 184 cm
In the second case of image formation , v becomes u and u becomes v only then image formation in the second case is possible.
The difference between two object distance ie( v - u ) is the distance by which lens is moved so
v - u = 82.4 cm
A gravitational force between objects depends on two things- their masses and the distance between them. So the greater the mass and the less distance there is, the more gravitational force and is the mass is less and the distance is great the gravitational force is weak
Answer:
pressure = density x g x height
= 1000 x 10 x 6 Pascal
=60000 Pascal
OR 60 kP
Answer:
Explanation:
given,
Power source = 5 V
R₁ = 25 Ω
R₂ = 50 Ω
a) when they are arranged in series
R = R₁ + R₂
R = 25 + 50
R = 75 Ω
b) current = I = 
I = 
I = 0.067 A
so, the resistors are connected in series hence current in both the resistor will be 0.067 A.
c) when they are arranged in parallel


R = 16.67 Ω
d) current through the battery 
= 0.3 A
current through 25 Ω resistor = 
current through 50 Ω resistor = 
Combined the speed force with the flash is speed and zoom s speed and then get 24=48,28
