Answer: There are 9 molecules.
Explanation: 3H2O has 6 hydrogen atoms and 3 oxygen atoms. Heres a diagram.
HHO + HHO + HHO = 3H2O
Answer:
Part a)
Part b)
Part c)
Part d)
Part e)
Part f)
It is independent of the speed of the object so all part answers will remain the same
Explanation:
Part a)
As we know that Point P is at height 5R while point Q is at height R
so the work done by gravity from P to Q is given as
Part b)
When it reaches to the top of the loop then its final height from ground is
h = 2R
so work done from P to Q is given as
Part c)
Potential energy at P point is given as
Part d)
Potential energy at Q point is given as
Part e)
Potential energy at top point is given as
Part f)
Since all the answer from part a) to part e) depends only upon the position of the object.
So here we can say that it is independent of the speed of the object so all part answers will remain the same
The correct answer is HYDROGEN
<span>Acceleration is the change in velocity divided by time.
We can find acceleration a, by the following formula
a=v-u/t
where,
v is the final velocity (in this question v=8.0 m/s)
u is the initial velocity (since the hamster starts from rest, u=0)
t is the time taken (i,e 3.0 second)
now by applying the formula we have,
a = 8.0 - 0 / 3
= 8 / 3
= 2.65 m/s</span>²<span>
The acceleration is 2.65 meters per second squared</span>
Answer:
6 x 10³ [m]
Explanation:
La notación científica corresponde a multiplicar el primer numero por una base de 10 elevada a la potencia requerida, esa potencia se determina por la cantidad de ceros después del numero. Para el ejercicio.
6000 [m] = 6 x 10³ [m]
Elevado a la tres, ya que se tienen 3 ceros después del numero seis.
Otro ejemplo seria 25000; 25 x 10³
Mas ejemplos:
3645 = 3.645 x 10³ (tres números a la derecha después del primer numero)
550000 = 550 x 10³, también es igual a 55 x 10⁴.
