Answer: the potental with twice larger radius 0.5* Vo ( being Vo =100V)
Explanation: In order to solve this proble, we know that teh potential due to charged sphere relative V=0 at infinity, we have
Vo=k*Q/R where R is the sphere radius
if we enlarge the radius to 2R the
V= k*Q/2*R = Vo/2
Answer:
Yes, the amount of Iron can affect the growth of plant.
Explanation:
Iron is essential micro-nutrient for the growth of plant but it is required only in small amount. Iron is required when plant produces chlorophyll and this gives plants oxygen and healthy green color but if a plant is suffering from iron deficiency then the plant's growth becomes stunted and leaves color changes to yellow. For plants requirement of iron is just 1 to 1.5 lb per acre whereas, requirement of nitrogen is 75 to 200 lb per acre.
Answer:
f = c / λ
Explanation:
Electromagnetic waves are types of periodic waves. They propagate with the same speed as light (3 * 10⁸ m/sec).
Therefore:
velocity of wave = c
Now, the equation that relates speed of wave and its frequency is as follows:
c = λf
where:
c is the speed of wave
f is the frequency of the wave
λ is the wavelength of the wave
Solve the above equation for frequency, we will end up with:
f = c / λ
Answer:
B. No. He presented no scientific data to support his claim.
Explanation:
It is given that,
Speed of an automobile is 25 km/h or 6.95 m/s
Kinetic energy of the automobile is 
(a) Kinetic energy of automobile s given by :
(b) If the velocity of the car is increased to 45 km/hour or 12.5 m/s, new kinetic energy becomes :
(c) If the velocity is increased to 80 km/hour, 22.23 m/s, So
Hence, this is the required solution.
