This question is incomplete, but I can do it for you, considering the equation to be *In its most famous form*:
A+B⇒C+D
A and B here are the reactants, while C and D are the products.
The reactants are generally the input materials in the beginning of any chemical reactions and they usually, if not always, are on the left hand side of the chemical equation. While the products are on the right hand side and are the final output of the chemical reaction.

Hope this helps.

A 30.0 kg child, initially at rest, slides down a 2.0 m tall slide. The child reaches the bottom of the slide with a speed of 6
HACTEHA [7]

Answer:

Explanation:

Total energy is constant

E = mgh + ½mv² + Fd

At the top of the slide, all energy is potential

E = mgh + 0 + 0

At the bottom of the slide, all potential energy has converted to kinetic and work of friction.

mgh = ½mv² + W

W = mgh - ½mv²

W = 30.0[(9.81)(2.0) - ½6²]

W = 48.6 J

Use F = 1/T as your basis:
skelet666 [1.2K]
  • Time Period=T=2.5×10^{-3}s

Now

Frequency:-

\\ \rm\rightarrowtail \nu=\dfrac{1}{T}

\\ \rm\rightarrowtail \nu=\dfrac{1}{2.5\times 10^{-3}}

\\ \rm\rightarrowtail \nu=0.4\times 10^{3}

\\ \rm\rightarrowtail \nu=400Hz

During a circus act, a performer thrills the crowd by catching a cannon ball shot at him. The cannon ball has a mass of m1 = 8.5
lbvjy [14]

Answer:

v = 0.92 m/s

Explanation:

As we know that there is no external horizontal force on the cannon ball + performer

So here total momentum of the system must be conserved

so we will have

m_1v_1 = (m_1 + m_2) v_f

m_1 = 8.5 kg

v_1 = 8.1 m/s

m_2 = 66 kg

now from above equation we have

8.5 \times 8.1 = (8.5 + 66) v

v = 0.92 m/s

When you ride your bike around a corner at 10 m/s, you are accelerating?
WINSTONCH [101]

When you ride your bike around a corner at 10 m/s, you are accelerating. Acceleration is caused by any forces. Sliding friction keeps you in the seat when a car goes around a corner. If you throw a ball into the air, Earth exerts a force on the ball.
