I'm a mad scientist
Answer:
Explanation:
Use that:
Then use the 2nd Newton's Law of Motion:
At x = 0.3 and y = 0.6, we can find the acceleration as:
(in SI unit)
Then the magnitude of the acceleration on that point is:
(SI Unit)
Answer:
F1= 122.93 N
Explanation:
Pascal´s Principle
Pascal´s Principle can be applied in the hydraulic press:
If we apply a small force (F1) on a small area piston A1, then, a pressure (P) is generated that is transmitted equally to all the particles of the liquid until it reaches a larger area piston and therefore a force (F2) can be exerted that is proportional to the area (A2) of the piston:
P=F/A
P1=P2
Formula (1)
Data
D1 = 1.85 cm : primary cylinder piston diameter
D2 = 24.5 cm : secondary cylinder piston diameter
m = 2200-kg : car mass
Piston area calculation
A1= 2.688 cm²
A2 = 471.435 cm²
Calculating of the weight of the car (W)
W = m*g = 2200-kg * 9.8 m/s² = 21560 N
Calculation of the force in Newtons to be exerted on the primary cylinder piston
Data:
A1= 2.688cm²
A2= 471.435 cm²
F2 = W= 21560 N
We replace data in the formula (1)
F1= 122.93 N
Answer:
a. πi(r₁² + r₂²)
b. πi(r₂²- r₁²)
Explanation:
(a) Find the net dipole moment of this system.
The magnetic dipole moment, μ = iA where i = current and A = For area
For the circular loop with radius r₁, and current i₁ in a clockwise direction, i₁ = + i positive
μ₁ = i₁A₁
= +i(πr₁²)
= πir₁²
For the circular loop with radius r₂, and current i₂ in a clockwise direction, i₂ = +i
μ₂ = i₂A₂
= +i(πr₂²)
= πir₂²
The net dipole moment, μ = μ₁ + μ₂
μ = μ₁ + μ₂
= πir₁² + πir₂²
= πi(r₁² + r₂²)
(b) Repeat for the reversed current in the inner loop
With the reversed current in the inner loop, the current is negative. So i₂ =-i
μ₁ = i₂A₁ = -i(πr₁²) = -πir₁²
So,
μ = μ₁ + μ₂
= -πir₁² + πir₂²
= πi(-r₁² + r₂²)
= πi(r₂²- r₁²)
