Answer:
Keep flammables away
Explanation:
this would avoid anything catching on fire or burning down
<h2>
Answer:</h2>
Both of them will have same kinetic energy.
<h2>
Explanation:</h2>
- Kinetic energy is the energy of motion, every object in motion posses some kinetic energy.
- Kinetic energy can be calculated by the given formula,
i.e, K.E = 1/2 mv² .
Where, K.E is kinetic energy,
m is mass of the object
v is the velocity of the object
- On observing the formula we can state that K.E is directly proportional to mass(m) and velocity(v) of the object.
- Obviously, birds have more mass than bees but in question it has given 10 Kg of bees and 10 Kg of birds which means mass is same and also both of them are travelling with same velocity i.e 10m/s and hence both of them will have same kinetic energy(as both of the variables i.e m and v are same).
Result: Both bees and birds have same kinetic energy.
Answer:
c) 10 millimeters (mm)
Explanation:
The unit conversions are as follows:
1 cm = 10 mm (millimeter)
1 cm = 0.01 m (meter)
1 cm = 0.00001 km (kilometer)
1 cm = 10000 μm (micrometer)
Based on the above conversions:
Therefore, 0.1 cm = 10 mm is incorrect instead it is 0.1 mm
Answer:
32.5 moles of O2(g) are necessaries for a complete reaction
Explanation:
Based on the reaction of combustion of C4H10(g):
C4H10(g) + 13/2 O2(g) → 4CO2(g) + 5H2O(g)
<em>1 mole of C4H10 needs 13/2 moles O2 for a complete reaction.</em>
<em />
That means, the moles of O2 required for a reaction of 5.00 moles of C4H10 are:
5.00 moles C4H10 * (13/2mol O2 / 1mol C4H10) =
32.5 moles of O2(g) are necessaries for a complete reaction
