1.) Use the formula to solve -
1/f = 1/do + 1/di; Where f = focal length; 1/do + 1/di
1/f = 1/do + di
1/8 = 1/25 + 1/?
.125 = .04 + 1/di
.125 -.04 = 1/di (transferred .04 to the left side of the equation)
.085/1 = 1/di
.085di/.085 = 1/.085 (multiplied both sides by di and divided both sides by .085)
di = 11.76 or 12
2.) Therefore, 12 cm is the distance from the image to the mirror
The bending of light rays is the result of refraction of light passing through the lens. A converging lens is curved on both sides such that the rays coming out of it come together at a point (converge). The point at which the right rays meet after refraction is called the focal point which is a real in the convex lens.
Answer:5041.90 m/s
Explanation:
The escape velocity equation is:
(1)
Where:
is the escape velocity
is the Universal Gravitational constant
is the mass of Mars
is Mar's radius
Solving:
(2)
Finally:
This is the escape velocity on Mars
Every atom with 15 protons in its nucleus
is an atom of Phosphorus.
The famous equation . . . E = m c² . . . doesn't say anything about where the mass comes from.
The total conversion of 1 kg of ANY mass into energy yields
(1kg) · (c²) Joules of energy.
E = (1 kg) · (c²) = (1 kg) · (299,792,458 m/s)²
<em>E = 8.9876 x 10¹⁶ Joules</em>
To put this in easily understood terms, it's the amount of energy required to keep a 100-watt light bulb shining for 10,402,259,010 days.
(That's about 28.5 million years, at the current length of days and years.)
