Answer:
The horizontal distance d that the ball covers before it lands is 1.72 m.
Explanation:
Given,
Height of ramp 
Height of bottom of ramp 
Diameter = 0.17 m
We need to determine the horizontal distance d the ball travels before landing.
We need to calculate the time
Using the equation of motion




Next, we can find the ball's velocity
Using the kinetic energy formula



By applying the conservation of energy



We substitute the values into the equation


Next, we determine the horizontal distance d the ball travels before landing
Using the distance formula

Where. d = distance
t = time
v = velocity
We substitute the values into the formula


Thus, the horizontal distance d that the ball travels before it lands is 1.72 m.
Answer:
19.62 ms
Explanation:
t = Time taken = 2 s
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s² (we take downward direction as positive)
Using the equations of motion
The pebble's speed upon contact with the water is 19.62 ms
Answer:
The answer to your inquiry is Mass = 41230.7 g or 41.23 kg.
Explanation:
Data
Density = 0.737 g/ml
Mass = ?
Volume = 14.9 gal
1 gal = 3.78 l
Process
1.- Convert gallons to liters
1 gal ---------------- 3.78 l
14.9 gal ------------- x
x = 56.44 l
2.- Convert liters to milliliters
1 l ------------------- 1000 ml
56.44 l --------------- x
x = (56.44 x 1000) / 1
x = 56444 ml
3.- Calculate the mass
Formula
Density = 
Solving for mass
Mass = density x volume
Substituting values
Mass = 0.737 x 56444
Result
Mass = 41230.7 g or 41.23 kg.
If the products have three nitrogen atoms, the reactants must have had the same quantity, as mass is conserved in a chemical reaction.
