Use the formula KE = 0. 5 mv2. What is the velocity of a platform diver if her kinetic energy is 12,000 J and her mass is
40 kg?
Answers
[tex]\text{Kinetic energy,}\\\\~~~~E_k = \dfrac 12 mv^2\\\\\implies v^2 = \dfrac{2 E_k}m\\\\\implies v = \sqrt{\dfrac{2E_k}m}\\\\\implies v = \sqrt{\dfrac{2 \times 12000}{40}}\\\\\implies v = 24.49~~ \text{ms}^{-1}\\\\\text{Velocity of the platform diver is 24.49 m/s}[/tex]

A certain 48 V electric forklift can lift up to 7000 lb at a
maximum rate of 76 ft/min. What is its power? Round your
answer to the nearest hundreds.
Answers
Based on the information provided, the Power of the electric forklift to the nearest hundred is 12,000 W.
What is the formula for arriving at Power in physics?
The formula for calculating power in physics is given as:
P = E/t; where P = Power, E is energy and t is time in seconds. It is also given as :
P = W/Δt
Recall that power is defined as the amount of work done within a specific amount of time.
Where W = Work and; Δt = time elapsed.
Recall that Work (w) = Force x distance
Force here is usually domiciled in Newtons while distance is usually domiciled in meters.
7000 pounds or Lbs to Newtons is
7000 x 4.4482216153 = 31137.551307 N
So let's convert the distance to Meters.
1 foot = 0.3048m
Therefore, 76ft = 23.1648 m
Thus, Work = 31137.551307 X 23.1648 (That is Force in Newtons x distance in meters.)
Work = 721, 295.148516 N·m
Recall that power is given as:
P = W/Δt
= 721,300/60 seconds
= 12,021.6666667, to the nearest hundred, and we have:
P = 12,000 W

Look at the incomplete balanced equation shown below. What three numbers would replace X, Y and Z in the equation? Give the numbers in order (for example: 2 6 3).
Answers
Answer:
3,6,9 is the answer it might be right but not sure
The balanced equation is C[tex]_3[/tex]H[tex]_8[/tex] + 5O[tex]_2[/tex] → 3CO[tex]_2[/tex] + 4H[tex]_2[/tex]O. An imbalanced chemical equation describes the products and reactants of a chemical process.
What is balanced equation?The balanced equation is indeed a chemical reaction equation in which the overall charge and the quantity of atoms for every element inside the reaction are identical for both the products and the reactants. In other terms, the mass plus charge on both side of the reaction are balanced.
An imbalanced chemical equation describes the products and reactants of a chemical process but does not include the quantities needed to meet mass conservation.
The carbon atom on lefts side is 3 while on right side it is 1
C[tex]_3[/tex]H[tex]_8[/tex] + O[tex]_2[/tex] → 3CO[tex]_2[/tex] + H[tex]_2[/tex]O
now balance oxygen
C[tex]_3[/tex]H[tex]_8[/tex] + 5O[tex]_2[/tex] → 3CO[tex]_2[/tex] + 4H[tex]_2[/tex]O
Therefore, the balanced equation is C[tex]_3[/tex]H[tex]_8[/tex] + 5O[tex]_2[/tex] → 3CO[tex]_2[/tex] + 4H[tex]_2[/tex]O.
