Light takes 162.1 seconds to travel from Venus to earth.
Explanation:
Speed of light=3 x 10⁸ m/s
distance between Venus and earth =30,220,000 miles=48634375680 m
Now the distance is given by d= v t
d= distance
v= velocity
t= time
48634375680= 3 x 10⁸ t
t=162.1 s
Answer:
14.7 Volt
Explanation:
C1 = 2.74 F, C2 = 7.46 F, C3 = 10.1 F
Here C1 and C3 are in parallel
So, Cp = C1 + C3 = 2.74 + 10.1 = 12.84 F
Now Cp and C2 are in series
1 / C = 1 / Cp + 1 / C2
1 / C = 1 / 12.84 + 1 / 7.46
C = 4.72 F
Let q be the total charge
q = C V = 4.72 x 40 = 188.8 C
Voltage across C2
V2 = q / C2 = 188.8 / 7.46 = 25.3 V
Voltage across C2 or c3
V' = V - V2 = 40 - 25.3
V' = 14.69
V' = 14.7 Volt
For those seeking for the answer, its a source of electrical energy.
Answer:
b
c
e
h
Explanation:
Note that the swing direction was not giving in the question and direction could be sideways (in a turn) or in a track or both
The question show something in common ...acceleration
So let's look at the statements and pick the correct ones
a is false while b is correct as the train is accelerating
c is correct. The train is accelerating even thou the speed could not be ascertained
d is false and not feasible as the train is accelerating
e is true as the train maybe moving at a constant speed in a circle
f is false. This could be constant velocity in a circle. Same as g (false)
h is true. It's accelerating
Answer:2538.43 N
Explanation:
Given
Mass of Log=205 kg
Ramp angle
Coefficient of Friction=0.855
log acceleration
Let T be the Tension
Here
T=849.04+132.63+1556.76=2538.435 N
