Answer:
360 ÷ 4 = 90
Example
A 360° circle is cut into 4 peaces in the form of + or × . It's one side is called 90°
Answer:
The work done by this force can be found via the following formula

Explanation:
Alternatively, the work done by the object is equal to the elastic potantial energy done by the spring.

Answer:
P₁ = 2.3506 10⁵ Pa
Explanation:
For this exercise we use Bernoulli's equation and continuity, where point 1 is in the hose and point 2 in the nozzle
P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ ρ v₂² + ρ g y₂
A₁ v₁ = A₂ v₂
Let's look for the areas
r₁ = d₁ / 2 = 2.25 / 2 = 1,125 cm
r₂ = d₂ / 2 = 0.2 / 2 = 0.100 cm
A₁ = π r₁²
A₁ = π 1.125²
A₁ = 3,976 cm²
A₂ = π r₂²
A₂ = π 0.1²
A₂ = 0.0452 cm²
Now with the continuity equation we can look for the speed of water inside the hose
v₁ = v₂ A₂ / A₁
v₁ = 11.2 0.0452 / 3.976
v₁ = 0.1273 m / s
Now we can use Bernoulli's equation, pa pressure at the nozzle is the air pressure (P₂ = Patm) the hose must be on the floor so the height is zero (y₁ = 0)
P₁ + ½ ρ v₁² = Patm + ½ ρ v₂² + ρ g y₂
P₁ = Patm + ½ ρ (v₂² - v₁²) + ρ g y₂
Let's calculate
P₁ = 1.013 10⁵ + ½ 1000 (11.2² - 0.1273²) + 1000 9.8 7.25
P₁ = 1.013 10⁵ + 6.271 10⁴ + 7.105 10⁴
P₁ = 2.3506 10⁵ Pa
5 ways to communicate better
Prepare yourself on the subject. ...
Structure your thoughts. ...
Keep it simple. ...
Listen to others with intent. ...
Engage well.
For an individual to succeed as well as for an organization to succeed, effective communication is crucial. Leaders who can articulate their ideas well are better at motivating and forming bonds with their staff. Furthermore, it's critical to positively and concisely convey your opinions.Whether or not communication is successful determines whether a relationship will succeed. Being able to explain your ideas clearly is only one aspect of effective communication; listening intently is another. It is the capacity to completely comprehend, to demonstrate empathy, and to provide feedback in light of the other person's answer. Simply said, it is the fruitful interchange of ideas and opinions between individuals or organizations.
