it is the evolution of butterfly
Answer:
4.167
4.83871 cm
Explanation:
u = Object distance
v = Image distance = 25 cm
f = Focal length = 6 cm
Angular magnification is given by

The angular magnification of the lens is 4.167
Lens equation

The closest distance by which the object can be examined is 4.83871 cm
The ramp has dimensions of 20 m length and 4 m height. The angle made by the ramp on the horizontal ground is
θ = sin⁻¹ (4/20)
After getting the angle, the force required to move the box can then be solved given that the mass of the box is known and also the coefficient of friction of the ramp
The nail I believe because once the water heats up the nail it creates a reaction and once the nail gets red from being hot enough it creates energy
If the bulb's resistance doesn't change, the power it uses is proportional to the square of the voltage. So doubling the voltage quadruples the power.
On 220 V, the bulb uses (4 • 40w)= 160 W.
It glows very brightly.
For a very short time.
Because it also gets very hot, and burns out.
After a few seconds, it uses zero watts.
