Answer:

<h2>6 m/s</h2>

Explanation:

The speed of the man can be found by using the formula

v =  \frac{d}{t}  \\

d is the distance

t is the time taken

From the question we have

v =  \frac{30}{5}  \\

We have the final answer as

<h3>6 m/s</h3>

Nuclear power is an alternate source of energy.

  • As much as there are problems with disposal of radioactive wastes, nuclear energy does from power plants does not release carbon dioxide into the atmosphere.
  • Burning of fossil fuel creates an environmental mess by releasing pollutants into the atmosphere.
  • This way, global warming can result.

Write a balanced chemical equation for the incomplete combustion of methane to produce CO(g) as the only carbon-containing produ
Brums [2.3K]

Answer:

2CH4(g)+3O2(g)→2CO(g)+4H2O(g)

Explanation:

Start with methane (CH4) and the gas product CO. It is safe to assume that the remaining products and reactants are O2 and H2O. There we have an unbalanced equation CH4+O2->CO+H2O after which it can be balanced as above.

A discus thrower throws a 1.6kg discus at 25m/s what's the kinetic energy?​
Ilya [14]

Answer:

<h2>500 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2} \\

where

m is the mass

v is the velocity

From the question

m = 1.6 kg

v = 25 m/s

We have

k =  \frac{1}{2}  \times 1.6 \times  {25}^{2}  \\  = 0.8 \times 625 \\  = 500

We have the final answer as

<h3>500 J </h3>
