Particles in a SOLID have a small amount of energy, vibrate, and are stuck in place?
Answer:
3521 seconds
Explanation:
The power that the television uses is calculated multiplying the current by the voltage:
P = I * V
with I = 0.71 A and V = 120 Volts, we have:
P = 0.71 * 120 = 85.2 W
To find the time it takes to consume 3*10^5 Joules, we need to know that the total energy consumed is equal to the power times the amount of time, so:
E = P * t
with E = 300000 and P = 85.2, we have:
300000 = 85.2 * t
t = 300000/85.2 = 3521.13 seconds = 3521 seconds
Answer:
Explanation:
At the time of a body achieving terminal velocity, the drag force becomes equal to the weight of the body less the buoyant force by the surrounding medium which can be represented by the following equation
Where r is radius of the body , d is density of the material of the body σ is density of the medium and n is coefficient of viscosity of the medium and v is terminal velocity.
Simplifying
v =
Assuming the value of density of air as 1.225 kg/m³ and putting other given values in the formula we get
v = [/tex]
v = 387 x 10⁻⁵ m/s
Terminal velocity = 387 x 10⁻⁵ m/s
Time taken to fall a distance of 100 m
=
= 2.6 x 10⁴ s.
R 3/4 = (R3 * R4) / (R3 + R 4) = ( 9 * 18 ) /(9 + 18 ) = 162 / 27 = 6 Ohms
R e = R 1 + R 2 + R 3/4 + R 5 = 3 + 6 + 6 + 15 = 30 Ohms
I = U / Re = 90 V / 30 Ohms = 3 A
Finally for the voltage U 3/4 ( the parallel portion of the circuit ):
U 3/4 = 6 Ohms * 3 A = 18 V
Answer: 18 V
Answer:
1.25 m
Explanation:
This is the vertical height not the distance along the slope.
