Answer:
The molecular formula for the compound is C4H8.
Explanation:
Emperical formula is CH2
Molar mass = 56 g/mol
Molar mass = (CH2)n
56 = (12 + 1×2)n
56 = (12 + 2)n
14n = 56
n = 56/14 = 4
Molecular formula = (CH2)n = (CH2)4 = C4H8
Answer:
si la. carga es positiva experimenta una fuerza en el sentido del campo
en cambio si la carga es negativa,experimenta una fuerza en sentido contrario al campo
You are correct...amplitude will be the answer
Answer:
the result = g .The correct answer is d
Explanation:
For this problem let's start by finding the center of mass of objects
= 1 / M ∑
we apply this equation to our case
M = m + 2m + 3m
M = 6m
x_{cm} = 1 / 6m (x₁ m + x₂ 2m + x₃ 3m)
x_{cm} = 1/6 (x₁ + 2 x₂ + 3x₃)
We apply Newton's second law to this center of mass
dp / dt = M a
d (M v_{cm}) / dt = M a
let's find the speed of the center of mass
v_{cm} = 1 / 6m (m v + 2m 0 - 3m v)
v_{cm} = ⅓ v
M d v_{cm}/ dt = M a
d v_{cm} / dt = a
at the center of mass the external force of the system is applied, which is the force of gravity
dv_{cm} / dt = g
therefore the result
a = g
The correct answer is d
Answer:
So average speed of the earth in miles per hour will be equal to
Explanation:
We have given average speed of the earth v = 29783 km/sec
We have to convert this speed into miles per hour
For converting the speed in miles per hour first we have to convert km to miles and sec to hour
As we know that 1 km = 0.6213 miles
And 1 sec = 0.000277 hour
So
So average speed of the earth in miles per hour will be equal to
