DNA 39 s unique structure enables the molecule to copy itself during cell division. ... Much like a spiral staircase it has two single strands that join and twist together.
Explanation:
Soils develop different horizons due to the amount of weather that is being exposed to each individual layer. What separates one horizon from another is the properties that make up each layer.
Answer:
A barometer
Explanation:
It is commonly used to measure atmospheric pressure
Kinetic energy = 0.5*M*V^2
Q7-
0.5*3*(2^2)= 6J
Q8a-
0.5*2*(2^2)= 4J
0.5*4*(3^2)=18J
the second ball has more kinetic energy.
Q8b-
at the max height, all the kinetic energy is converted to potential energy,
gravitational potential energy is = M*g*h
that theory would apply if you wanted to work out the maximum height achieved if the balls were thrown upward by rearranging. But, we are simply working out which ball will have more potential energy so:
First ball:
2kg*9.81(g)*10m = 196.2J
Second ball
4kg*9.81*10m= 392.4J
The second ball has more potential energy
