An oil tanker, initially traveling west at 18 km/h is accelerated uniformly until it is traveling east at 21.6 km/h. The acceleration is 0.20 m/s2 towards the east. Compute the total displacement from the tanker’s initial position.Answer in meters.
Answers
Answer:
27.5 m
Explanation:
Given:
u = 18 km/h = 5 m/s
v = 21.6 km/h = 6 m/s
a = 0.20 m/s²
Find: s
v² = u² + 2as
(6 m/s)² = (5 m/s)² + 2 (0.20 m/s²) s
s = 27.5 m

Answer:
Boiling is the "rapid vaporization of liquid" when the liquid is heated at the point where the pressure of the vapor is equal to the pressure exerted by the atmosphere in the liquid.
So during the boiling, the vaporization of the water is also occurring but is a little bit more complex.
Some questions that you may ask your friend to differentiate those two phenomena are:
Which one is used to cook things like pasta? (boiling)
in which process, a liquid is transformed into a gas? (evaporation)
Which one includes the other? (boiling)
Final answer:
Evaporation and boiling are both phases changes, but they differ in the specifics of how and when they happen. These differences involve the temperature and location within the liquid where they occur, as well as the speed of the process.
Explanation:
To differentiate between evaporation and boiling, you could ask your friend these questions:
- Does the process occur at any temperature or only at a specific temperature (the boiling point)? (Evaporation can occur at any temperature while boiling only occurs at the boiling point.)
- Does the process occur throughout the liquid or only at the surface? (Boiling occurs throughout the liquid while evaporation happens only at the surface.)
- Is the process slow or fast? (Evaporation is a slow process while boiling is relatively quick.)
By asking these questions, your friend will be able to identify the key differences that separate evaporation from boiling.

As the particle moves along a straight line, the magnitude of the velocity is equal to the speed and the direction is along the direction of motion.
To find out the speed of the particle, we have to differentiate the given equation of motion. That is,
Speed =
For t=6 s, we get
Speed = 60₋ 9 × 6 = 60₋54=6 m/s
The speed of the particle at t=6 s is 6 m/s.

There are forces are acting on the block: 1. Fs = upward force from scale (up = + Fs) 2. W = downward weight force (down = - W) 3. Fb = upward buoyancy force (up = + Fb)
Since the block is at rest, (net force = 0), the force equation is:
Fs + Fb - W = 0 ~(eq1)
Substituting Fs, Fb and W into ~(eq1): ==> {m (on scale) x g} + {ρ x V x g} - (m (block) x g} = 0
Dividing both sides of equation by g: m (on scale) + (ρ x V) - m (block) = 0 ~(eq2)
Given: V = volume of water displaced = 40% volume of the block = 0.40 x V (block)
Substituting 0.40 x V (block) into ~(eq2): m (on scale) + (ρ x 0.40 x V (block)) - m (block) = 0 ~(eq3) where, m (on scale) = 5.6 g ρ = density of water at 20ºC = 0.99821 g/cm^3 m (block) = 50 g
Substituting m (on scale), ρ and m (block) into ~(eq3): 5.6 g + (0.99821 g/cm^3 x 0.40 x V (block)) - 50 g = 0 ~(eq4)
Simplifying ~(eq4) and solving for V (block): ==> 5.6 g + 0.399284 g/cm^3 x V (block) - 50 g = 0 ==> 0.399284 g/cm^3 x V (block) - 44.4 g = 0 ==> 0.399284 g/cm^3 x V (block) = 44.4 g ==> V (block) = 44.4 g / (0.399284 g/cm^3) ==> V (block) = 111.199 cm^3
ρ (block) = density of block = m (block) / V (block) = 50 g / 111.199 cm^3 = 0.449644 g / cm^3
B) None of the remaining light bulbs will be on.
C) Only the bulb closest to the switch will be on.
D) All three remaining light bulbs will be brighter than before.
Answers
The correct answer is option B) None of the remaining light bulbs will be on.
What will happen if one light bulb is removed from a series circuit?
In a series connection when a bulb is removed, it will be creating a open circuit. Since the circuit is series and is open at a point current will not flow and hence the other bulb will not glow.
Why did the series circuit stop working when one of the light bulbs was removed?
That's because the basic requirement for the circuit to operate a continuous, closed-loop path is no longer met. This is the main disadvantage of a series circuit. If any one of the light bulbs or loads burns out or is removed, the entire circuit stops operating.
