Answer:
In the morning the molecules were moving away from each other with a smaller speed than when the truck was carrying the substance.
Explanation:
The question is incomplete! circuit figure is attached below and answer and explanation is provided below.
Answer:
Bulb_A = Bulb_B = Bulb_D and Bulb_C = 0.
Explanation:
What happens when switch is open?
When the switch is open Bulb_C is open circuited meaning that there is no way for the current to flow through it. This path offers infinite resistance to the current therefore, current will try to take a least resistance path that is through Bulb_B.
So eventually, when the switch is open the circuit becomes a simple series circuit with path From battery to Bulb_A to Bulb_B to Bulb_D to battery with Bulb_C = 0.
What happens in a series circuit?
We know that in a series circuit, there is only one path for the current to flow therefore, same current will flow through all the series Bulbs and their brightness will be same. Bulb_A = Bulb_B = Bulb_D
Brightness in a series circuit:
We also know know that in a series circuit, resistance gets summed up and voltage across each Bulb gets shared which results in less power dissipation that's why Bulbs connected in series appear dimmer as compared to when they are connected in parallel.
The answer would be 9,940 K is the temperature of Sirius B.
Answer:
The answer to your question is W = 3695464.4 J
Explanation:
Mechanical work is the force applied to an object multiply by the distance this object move as a consequence of the force.
Formula
Work = W (J)
Force = F (N)
distance = d (m)
W = F x d
Substitution
F = 6818.2 N
d = 542 m
W = 6818.2 x 542
Simplification and result
W = 3695464.4 J
Answer:
0.176 m/s
Explanation:
given,
mass of the puck, m = 170 g
Length of the ramp, L = 3.6 mm
angle of inclination, θ = 26°
the minimum speed require to reach at the top of the ramp
using equation of motion
v² = u² + 2 a s
final speed of the puck is zero
0² = u² - 2 g s

height of the pluck


h = 1.58 mm
h = 0.00158 m
now,

u = 0.176 m/s
hence, the speed required by the pluck to reach at the top is equal to 0.176 m/s
