<u>Answer;</u></h3>
= 5.102 m
<h3><u>Explanation;</u></h3>
The total energy, i.e. sum of kinetic and potential energy, is constant.
That is; E = KE + PE
Initially, PE = 0 and KE = 1/2 mv^2
At maximum height, velocity=0, thus, KE = 0 and PE = mgh
Since, total energy is constant (KE converts to PE when the ball is rising).
Therefore, KE = PE
or, 1/2 mv^2 = mgh
or, h = v^2 /2g
= 10^2 / (2x9.8)
=<u> 5.102 m</u>
Okay, I am going to use solar prominence and solar flares.
So, Solar Prominence is a large, bright, gaseous feature extending outward from
the Sun's surface, often in a loop shape. Prominence are anchored to
the Sun's surface in the photo-sphere, and extend outwards into the Sun's
corona.
A solar flare is a sudden flash of brightness observed near the Sun's
surface. It involves a very broad spectrum of emissions, requiring an
energy release of up to 6 × 10²⁵ joules of energy (roughly the
equivalent of 160,000,000,000 megatons of TNT, over 25,000 times more
energy than released from the impact of Comet Shoemaker–Levy 9 with
Jupiter).
Hope this helps
Answer:
h = 5.05 m
Explanation:
given,
mass of pole vaulter, m = 64 Kg
speed of the vaulter,V = 10.2 m/s
horizontal component of velocity in air, v = 1 m/s
height of the jump,h = ?
using energy conservation
initial height of the vaulter is equal to zero.
h = 5.05 m
height of the jump is equal to 5.05 m.
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.
