Earth's rotation causes winds to veer to the west or to the east. This is known as the Coriolis effect.
Lesson 1.06
Question 5 options:
True
False
Earth's rotation and spherical shape cause winds to veer to the right (in the northern Hemisphere) or to the left (in the southern Hemisphere) of the direction they want to go. This is known as the Coriolis effect.
If you didn't know that you're on a rotating Earth, and you looked at the patterns of the winds, you'd think there's some kind of force that's making the airflow veer to the right or left of the direction it actually wants to go. This is known as the Coriolis force. It's a"pseudo force", because it doesn't really exist. It only LOOKS like it's there, because of the Earth's rotation and spherical shape..
The statement "Earth's rotation causes winds to veer to the west or to the east" is true about the Coriolis effect.
What is the Coriolis effect?Fluid materials such as wind and ocean currents take different directions depending on the hemisphere, this movement of deviation is called the Coriolis effect.
Characteristics of the Coriolis effectThe Coriolis effect occurs when masses of air or water move along terrestrial meridians, and their trajectory and speed are modified by it.The winds or ocean currents that move along a meridian are diverted by accelerating in the direction of rotation (east) if they go towards the poles or the opposite (west) if they go towards the equator.Therefore, we can conclude that the force that tends to deflect the trajectory of objects moving across the entire earth's surface is known as the Coriolis effect.

Calculate the total mechanical energy of a 2 kg duck flying at 5 m/s, at a height of 10 meters above the ground.
Use g = 10 m/s?
A.) 25J
B.) 45 J
C.) 205 J
D.) 225J
Answer:
Total mechanical energy = 225 J
Explanation:
Given:
Mass of duck (m) = 2 kg
Speed of duck (v)= 5 m/s
Height of duck from ground (h) = 10 m
Gravitation acceleration (g) = 10 m/s²
Find:
Total mechanical energy
Computation:
Total mechanical energy = Kinetic energy + Potential energy
Total mechanical energy = (1/2)mv² + mgh
Total mechanical energy = (1/2)(2)(5)² + (2)(10)(10)
Total mechanical energy = 25 + 200
Total mechanical energy = 225 J

Time = 0.0001s
Final velocity = 400m/s
Unknown:
Acceleration of the object = ?
Solution:
Acceleration is the rate of change of velocity with time;

How does static work if items are not touching?
Answer:
Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called 'charge' being moved from one surface to the other. Charged objects pull on other uncharged objects and may either push or pull on other charged objects.

4. A baseball is pitched with a speed of 35 m/s. If the baseball has a mass of 0.146 kg, what is its
Kinetic energy? (35 m/s = 78 mph just FYI - use the m/s)
Answer: 89 J
Explanation:
The kinetic energy of the baseball with the given mass and speed is 89.425 Joules.
What is the Kinetic energy of the baseball?Kinetic energy is simply a form of energy a particle or object possesses due to its motion.
It is expressed as;
K = (1/2)mv²
Where m is mass of the object and v is its velocity.
Given the data in the question;
Mass of the baseball m = 0.146kgVelocity v = 35m/sKinetic energy of the baseball K = ?K = (1/2)mv²
K = (1/2) × 0.146kg × (35m/s)²
K = 0.5 × 0.146kg × 1225m²/s²
K = 89.425kgm²/s²
K = 89.425J
The kinetic energy of the baseball with the given mass and speed is 89.425 Joules.

Diameter
Circumference
Answer:
Diameter
Explanation:
I know that circumference is dependent, so diameter has to be independent
The circumference is dependent, so diameter has to be independent.
What are independent variables?Even though everything can be almost always related to its reason, when we talk about two related things, there might happen that one of those things is dependent on other.
If a variable is taking its values independently of any visible direct cause, then that variable is called independent variable.
Diameter is the line from one point in the circle to the other point through the center of the circle.
The circumference of the circle that has a radius of r is the product of diameter to the pie value.

. A hydraulic lift consists of two cylindrical pistons, one with a radius of 1.5 m and
the other with a radius of 8.0 cm. What force must be applied to the smaller piston if
a crate with a mass of 1.5x103 kg is to be raised on the larger piston?
F=42N,
Answer:
The force that must be applied to the smaller piston if the crate is to be raised by the larger piston is approximately 42 N
Explanation:
The given parameters of the hydraulic lift are;
The diameter of one of the pistons = 1.5 m
The diameter of the other pistons = 8.0 cm = 0.08 m
The mass of the crate to be lifted with the larger piston, m = 1.5 × 10³ kg
The weight of the mass to be lifted by the larger piston, W₁ = m × g
Where;
g = The acceleration due to gravity = 9.8 m/s²
Therefore;
W₁ = 1.5 × 10³ kg × 9.8 m/s² = 14,700 N
The area of the surface of the circular piston, A = π × r²
Where;
r = The piston's radius
∴ The area of the larger piston with 1.5 m radius, A₁ = π × (1.5 m)² = 7.06868347058 m² ≈ 7.07 m²
A₁ ≈ 7.07 m²
The area of the smaller piston with 0.08 m (8 cm) radius, A₂ = π × (0.08 m)² = 02010619298 m² ≈ 0.02 m²
A₂ ≈ 0.02 m²
The pressure in the fluid of the hydraulic lift is constant, therefore, we have;
The pressure applied to the larger piston with 1.5 m radius, P₁ = The pressure applied to the smaller piston with 0.08 m radius, P₂
∴ P₁ = P₂
[tex]Pressure = \dfrac{Force}{Area}[/tex]
[tex]P_1 = \dfrac{W_1}{A_1} = \ P_2 = \dfrac{F_2}{A_2}[/tex]
[tex]\therefore \dfrac{W_1}{A_1} = \ \dfrac{F_2}{A_2}[/tex]
Where, F₂, represents the force that must be applied to the smaller piston if the crate is to be raised by the larger piston;
[tex]\therefore F_2 = A_2 \times \dfrac{W_1}{A_1}[/tex]
Given that we have the ratio of two areas which have π as a factor, we have;
[tex]\therefore F_2 = A_2 \times \dfrac{W_1}{A_1} = 0.08^2 \times \pi \times \dfrac{14,700}{1.5^2 \times \pi } = 41.81 \overline 3[/tex]
The force that must be applied to the smaller piston if the crate is to be raised by the larger piston, F₂ = 41.81[tex]\overline 3[/tex] N ≈ 42 N.
