Answer:
a) 1.22 s
b) 9.089 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s²
Time taken by the ball to reach the highest point is 1.22 seconds
The maximum height the ball will reach above the ground is 1.75+7.339 = 9.089 m
With the flow of the water
Answer:
two ampheres
Explanation:
the formula for calculating voltage is V=IR so if the current which is I is 2 and the resistance which is R is decreased to one forth then we will say
R=x multiplied by 1/4=x/4
V=2x/4 cross multiply then we have
since the voltage is constant then it is=1
so 4=2x divide both sides by 2 we then get 2 as our answer
It caused the balloons to turn into physical energy
Answer:
B. tablespoon
Explanation:
Considering the question given, a mole of water is small compare to the options given from the question aside the table spoon.
A mole of water is just 18g and that's equivalent to 18 mL.
18 mL of water will fill a table spoon but not a cup which is about 237mL. The wheel barrow and gallon bucket have larger volumes of which 18 mL of water will never fill them.
So, a mole of water can successfully fill a table spoon.
