Answer:
The speed of the other piece of the object is 13/4*v0, going to the right.
Explanation:
Assuming that no external forces acting during the explosion (as the time during which it happens is considered infinitesimal), total momentum must be conserved , same as it happens with the total mass, assuming that v₀ is much smaller than c (speed of light), so no conversion of mass into energy is done.
So, based on the information provided, we can write the following expression, assuming the positive direction to be the one to the right:
m*v₀ = -3/5*m*(v₀/2) + 2/5*m*vₓ
Solving for vₓ, we have:
vₓ = 13/4*v₀, to the right, as the value obtained is positive.
Answer:
Or in the other way:
Explanation:
For this case we need to remember that hectare is a measure of area. And we have the following ratios:
We can convert this into
We can convert this into
By dimensional analysis we assume that we can find the ratio in terms of distance like this:
And if we find the ratios in terms of distance we got:
Or in the other way:
Answer:
Explanation:
There is a chemistry category, but:
find the ratio by dividing by smallest value:
find and balance chemical formula:
2 molO and 1 mol C is needed for a complete reaction, therefore the limiting reactant is the O
solve for CO2 using the mol of O
convert mol to g again
Rotational kinetic energy <span>is the kinetic energy of an object, proportional to the object's moment of inertia and the square of its angular velocity.</span>
Explanation:
When,the vehicle has uniform velocity, it's acceleration becomes zero
