A GENE is a segment of DNA that carries a single unit of hereditary information.
Answer: B
Cohesion makes water stick together, which is vital in transporting nutrients from tree roots to other parts of the plant.
Answer:
your friend will wait for you for 2.2 minutes.
Explanation:
Given;
Distance of the journey, d = 50 km
your speed, v₁ = 88.5 km/h
your friends speed, v₂ = 94.5 km/h
The time taken before you reached the end of the trip;
The time taken before your friend reached the end of the trip;
The difference in time = (0.565 - 0.529) hour
= 0.036 hour
= 0.036 x 60 min
= 2.2 mins
Therefore, your friend will wait for you for 2.2 minutes.
Answer:
0.136 C
Explanation:
This question uses the simple idea of conservation of energy. We work with the assumption that energy loss is zero
At the top of the waterfall the water has maximum potential energy
Where
= Mass of water
= Acceleration due to gravity
= Height
Now at the bottom just before impact all of the potential energy is converted to kinetic energy and right after impact all this kinetic energy is converted to thermal energy ()
Where
= Mass of water
= Specific Heat Capacity of Water
= Change in Temperature
Equating the two equations
Since the value of is a constant, it is equal to 4186 J / (kg * C). We input all the given values into the equation and find the answer
