Answer:
The second one because there is less <em><u>distance between them.</u></em>
D. There's not enough research surrounding it. A big question is if they have side effects due to genetic modification that we don't know of.
(Not sure if you had D eliminated or? But it should be the correct answer)
Answer:the hare slept for 1 hr 55minutes.
Explanation: distance is changed to meters = 520m
Speed=distance/time
Speed of tortoise is 0.075m/s=520m/t
Crops multiplying t= 520/0.075 = 6933.3 seconds.
Speed for hare 16.7m/s =260m/t
ie 260m is half of the distance.
t =15.56seconds
Therefore the time slept by the hare = 6933.3- 15.56= 6917.74 seconds.
Converting to hours = 1hr. 55minutes is the time the hare slept.
Answer:
Explanation:
Let v be the terminal velocity of the bar .
emf induced in the bar of length L
= B L v where B is the value of magnetic field.
current i in the circuit containing resistance R
i = induced emf / R
BLv / R
Magnetic force in upward direction in the bar
F = BiL
= BL x BLv / R
B²L²v / R
For attainment of uniform velocity
magnetic force = weight
B²L²v / R = mg
so current
i = BLv / R
1. Changing from solid to a liquid is called melting / fusion and happen
at the melting/ fusion point.
Reason: melting point is a temperature at which a solid melt and converts into liquid by providing heat.
2. Changing from liquid to gas is called evaporation/boiling and happens at the evaporation/boiling point.
Reason. Evaporation is a process in which molecules from surface of liquid convert into gas.
3. Changing from a gas to a liquid is called condensation and happens at the condensation point.
Reason : In condensation process gas particles converts into liquid droplets.
4. Changing from liquid to a solid is called freezing and happens at the freezing point.
Reason : Freezing is a process that convert liquid into soilid state by decreasing temperature of that specific liquid,
