Answer:
a = 1 m/s² and
Explanation:
The first two parts can be seen in attachment
We use Newton's second law on each axis
Y axis
Ty - W = 0
Ty = w
X axis
Tx = m a
With trigonometry we find the components of tension
Sin θ = Ty / T
Ty = T sin θ
Cos θ = Tx / T
Tx = T cos θ
We calculate the acceleration with kinematics
Vf = Vo + a t
a = (Vf -Vo) / t
a = (20 -10) / 10
a = 1 m/s²
We substitute in Newton's equations
T Sin θ = mg
T cos θ = ma
We divide the two equations
Tan θ = g / a
θ = tan⁻¹ (g / a)
θ = tan⁻¹ (9.8 / 1)
θ = 84º
We see that in the expression of the angle the mass does not appear therefore you should not change the angle
The answer to your question Tropical Cyclones
I calculated on a sheet and used differentiation to solve the problems.
During the evacuation of a system containing large amounts of moisture, it may be necessary to prevent freezing by increasing pressure using a gas such as Nitrogen
The scientific name for nitrogen is N, and it is a flavorless and colorless element. The ground beneath our feet contains nitrogen, as does the water we drink and the air we breathe. In fact, nitrogen makes up the majority of the atmosphere on Earth, making up around 78% of the atmosphere.
Nitrogen, which is necessary for plant growth, can be "fixed" by lightning or given to soils through fertilizers. a flavorless gas with no color. The chemical industry depends on nitrogen. It is used to create explosives, nylon, nitric acid, fertilizers, and colors. Nitrogen is always represented as N2 when it is in a gaseous state. It belongs to the group of seven diatomic molecules.
