Answer:
Force of Tension = 1832.8 N
Explanation:
Any mass of object supported or pulled by a rope or cable is subject to a force of tension. Since the mass is raised by a cable, tension is involved.
Mathematically,
Tension = mass × gravity(9.8 m/s²)
Tension can be represented as
T = (m × g) + (m × a)
Where g is the acceleration due to gravity of the object the cable is supporting and a is the acceleration on the object the cable is supporting. And m is the mass of the object.
mass = 158 kg
a = 1.8 m/s²
g = 9.8 m/s²
T = mg + ma
T = m(g + a)
T = 158(9.8 + 1.8)
T = 158 × 11.6
T = 1832.8 N
Answer:
3.79 grams
Explanation:
22.4= STP volume . Molar mass of NH3=17.031
5.00 NH3 × (1 mol/22.4 L) =0.223
convert to grams->
0.223× 17.031= 3.79
Answer:
m = 79.1 grams
Explanation:
Given that,
Density, d = 2.26 g/mL
Volume occupies, V = 35 mL
We need to find the mass of the substance. We know that the density of an object is equal to the mass per unit volume. So,
d = m/V
So, the mass of the substance is 79.1 grams.
In the Lewis structure, each single bond drawn between elements contain two electrons. The electron dots represent the lone pairs. These are the electrons that take part in the reaction. To obey the octet rule, the oxygen must have eight electrons around it. The hydrogen is exempted from this rule. Therefore, you have to show two electrons.
Answer:
im pretty sure its a push or pull thing
Explanation:
Tensional stress is the stress that tends to pull something apart. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.
