Answer:There are two main types of friction, static friction and kinetic friction. Static friction operates between two surfaces that aren't moving relative to each other, while kinetic friction acts between objects in motion.
Answer:
144 W
Explanation:
The power absorbed by a resistor is the product of the current passing through it and the voltage drop across it. Hence
Other variations of this formula are derived using Ohm's law, 
is the resistance of the resistor. It is what causes the voltage drop.
Answer:
CB = 4.45 x 10⁻⁹ F = 4.45 nF
Explanation:
The capacitance of a parallel plate capacitor is given by the following formula:
C = ε₀A/d
where,
C = Capacitance
ε₀ = Permeability of free space
A = Area of plates
d = Distance between plates
FOR CAPACITOR A:
C = CA = 17.8 nF = 17.8 x 10⁻⁹ F
A = A₁
d = d₁
Therefore,
CA = ε₀A₁/d₁ = 17.8 x 10⁻⁹ F ----------------- equation 1
FOR CAPACITOR B:
C = CB = ?
A = A₁/2
d = 2 d₁
Therefore,
CB = ε₀(A₁/2)/2d₁
CB = (1/4)(ε₀A₁/d₁)
using equation 1:
CB = (1/4)(17.8 X 10⁻⁹ F)
<u>CB = 4.45 x 10⁻⁹ F = 4.45 nF</u>
Answer:
they can blend in with their suroundings
Explanation:
Answer:
A. 0.204203928 m
b. 0.1443939822
Explanation:
Givens:
Volume (V) = 160 m^3
velocity 1 (v1) = 3.00 m/s
velocity 2 (v2) = 6.00 m/s
Time (t) = 21.3 minutes = 1278 seconds
Side length = ?
V = A*v*t
A = s^2
V = s^2*v*t
s= 
A.
s = = 
= 0.204203928 m
B.
s = = 
= 0.1443939822 m
I hope this helped!! Have a good day.
