Answer:
d = 90 ft
Explanation:
As we know that after each bounce it reaches to 4/5 times of initial height
so we can say
so the distance covered is given as
here we know that
h = 10 feet
Answer:
<em>Electrical power</em>
Explanation:
<em>Electrical power:</em> Electric power (P) is defined as the energy (W) used or produced or transformed per seconds.
Power = Energy produced/transformed/time taken.
P = W/t................................ Equation 1
Where t = time taken
But,
W = VIt................................ Equation 2
Substituting equation 2 into equation 1
P = VIt/t
P = VI............................ Equation 3
or
P = V²/R or P = I²R.
The unit of power is J/s or Volt-ampere is called watt (W).
Large amount of electric power are required in the industry
1 kW = 1000 W
1 MW = 1000000 W
1 h.p = 3/4 kW.
<span>The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting. A virtual image is a copy of an object formed at the location from which the light rays appear to come.</span>
