Electromagnetic waves..............................
Answer:
See below
Explanation:
Distance = 27 + 13 = 40 km
Displacement = 27 - 13 = 14 km
The amount of energy transferred to an appliance is depends on its power and length of time it is switched on. The wires attached to the appliance conduct the electricity and send it to the main motor function.
Answer:
ΔV = 0.98 L
Explanation:
First, we will calculate the increased volume using Charles' Law:
where,
V₁ =initial volume = 18.9 L
V₂ = final volume = ?
T₁ = initial temperature = 15°C + 273 = 288 k
T₂ = final temperature = 30°C + 273 = 303 k
Therefore,
V₂ = 19.88 L
Now, we calculate the change in volume:
ΔV = V₂ - V₁ = 19.88L - 18.9 L
<u>ΔV = 0.98 L</u>
This is the volume of gasoline that will spill out.
The forces that act upon the suspending signage are as follows: (1) weight of the signage. This force is due to the pull of gravity. (2) Tensions (both x and y-components). Since there are 2 cables attached to the signage then, both of this cable will exert tension to the signage, pulling it upward.
