Choose all the answers that apply. Tall pea plants are dominant over dwarf pea plants. If two hybrids (Tt) are crossed
o 50% of the offspring will be Tt
o 25% of the offspring will be short
o 25% of the offspring will be tall
o 75% of the offspring will be tall
o 75% of the offspring will be TT

Explanation:

50% of the offspring will be Tt

25% of the offspring will be short

75% of the offspring will be tall

Using a punnet square diagram with T t on top, T t on the side we get results of TT, Tt, Tt, and tt. Since T (tall) is dominant it will over ride the small t that is paired with. Being out of 4 makes each square 25%. tt (small 25%), Talls being TT, and Tt being 75%.

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
