This is a problem that can be solved using free-fall motion analysis. Since the displacement (2.9m) is given, we can use the following equation to solve for the impact speed:
V^2 = 2gh
V = sqrt (2*9.8*2.9)
V = 7.54 m/s
Answer:
C
Explanation:
Voltage is doubled the power so the higher the voltage, the higher the power
It’s light seconds, now don’t mistake it as time
English Translation :
A gas at a temperature of 38 °C, have a volume of 21 Lts Liters. What volume will it have if the temperature rises to 67°C?
Solution :
Since, there is no information about pressure, let us assume it is constant.
So, by ideal gas equation at constant pressure :
Putting given volume and temperature ( in Kelvin ) in above equation, we get :
Hence, this is the required solution.
So trees are sorta like people at the top of very tall mountains we cannot breath the air that is up there it is sorta the same for trees it is not right amount of oxygen that they need to grow
