Answer:A) 19.8 seconds
B) 467.5 metres
Explanation: 100km/hr = 27.78m/s
So, it covers 27.78 metres in one second
Take the time it would cover 550m as x
Therefore 27.78m = 1second
550m = x
Cross multiplying
27.78x = 550m
Divide both sides by the coefficient of x
x = 550÷27.78
x = 19.8seconds
B) distance = speed × time
Speed = 85km/hr = 23.61m/s
Time = 19.8seconds
Therefore,
Distance = 23.61 × 19.8
Distance = 467.5m
We know that the electric field is equal to 1 E 6 V/m
The distance between the thundercloud and the ground is 1.6km = 1600m
Electric field = Voltage/distance
This means that the breakdown voltage must be equal to
V = 1 E 6 V/m * 1600m = 1.6 E 9 V = 1.6 GV
used cross breeding to purposely breed plan
studied a variety of pea plant traits
studied several generations of plants
In order to breed or cross one plant with another, Mendel opened the petals and removed the anthers from the flower and dusted the pistil with pollen from the plant he wished to cross it with and covered the flower with a small bag to prevent the pollen in the air from landing in the pistil. This process is called cross pollination.
Mendel considered 7 characters of pea plant for his study and did the study for several generations.
