Answer:
m₂ = 1.33 kg
Explanation:
1.50 rev/s = 3π rad/s
I₁ = ½(2.00)(0.50²) = 0.25 kg•m²
L₁ = I₁ω₁ = 0.25(3π) = .075π kg•m²/s
ω₂ = ω₁R₁/R₂ = 3π(0.5/0.75) = 2π rad/s
I₂ = L₂/ω₂ = 0.75π/2π = 0.375 kg•m²
I₂ = ½m₂R₂²
m₂ = 2I₂/R₂² = 2(0.375) / 0.75² = 1.33 kg
Answer:
The work down on satellite X by the force in terms of Kx is .
Explanation:
The work done is given as in terms of
Where ΔTE is the change in total energy.
This is given as
Rearranging it in terms of K_x gives
Answer: Voltage, resistance, current
Explanation:
I did it on edge
Answer:
Acceleration
Explanation:
Momentum is acceleration because acceleration is movement and momentum is movement.
Momentun = Movement
Acceleration = Movement
Momentum = Acceleration
Answer:
162500000.
Explanation:
Given that
Diameter of the wire , d= 1.8 mm
The length of the wire ,L = 15 cm
Current ,I = 260 m A
The charge on the electron ,e= 1.6 x 10⁻¹⁹ C
We know that Current I is given as
I=Current
q=Charge
t=time
q= I t
q= 260 m t
The total number of electron = n
q= n e
n=162500000 t
The number of electron passe per second will be 162500000.
