Answer:
The parents and offspring all have phenotype ww. That leaves 100% probability of short wings and 0% long wings.
Explanation:
If long wings are a dominant trait, that means short wings are recessive. If two short winged flies are crossed, each of their phenotypes are ww. Therefore, each of their offspring also have phenotype ww, or short wings.
Answer:
The riders work becomes a combination of gravitational potential,
kinetic energy and heat.
Explanation:
His work becomes gravitational potential as the raider gains height. This can be seen from the equation of gravitational potential:
,
where m is the mass, g is the gravity and h is the height. Since the rider's final position is higher than his starting position the change of gravitational position is greater than 0.
His work becomes kinetic energy as he gains speed: assuming he was at rest at starting position he must increase his speed to move to the top of the hill, and because kinetic energy depends on speed, part of his work becomes kinetic energy.
Finally, part of his work turns into heat due to all the losses because of the friction in the bicycle gears.
Teddyber continue to move forward because Newton law 1. moving object continue to move until something external make it to stop. no seat belt on teddy ber so only dashboard can make her stop. same if people in car and no seatbelt.
Answer:
acceleration is 1.59 m/s²
required % is 16.22 %
Explanation:
given data
radius = 63 m
speed = 10 m/s
to find out
acceleration of the car and acceleration due to gravity
solution
we know car is moving in circular path
so acceleration will be, a = .........1
put here value
a =
a = 1.59 m/s²
so acceleration is 1.59 m/s²
so acceleration due to gravity as a percentage is 9.8 m/s²
required % =
required % = 16.22 %
