A rubber duck of volume 2,500cm3 floats in water with 20% of its volume submerged. You want to hold the duck under water so it is at rest and completely submerged. How much force do you have to apply? If you release the duck, what will be its acceleration at that instant?
The force applied to the submerged rubber duck is 4.9 N.
Density of the rubber duck
The density of the rubber duck is calculated as follows;
ρ = S.G x density of water
ρ = 0.2 x 1000 kg/m³
ρ = 200 kg/m³
Force applied to the duckF = mg = (ρV)g
F = (200 x 0.0025) x 9.8
F = 4.9 N

Anne pushed a cart by 12 N. How far did the cart move if the work done was 9 J?
[tex]\\ \sf\longmapsto W=Fd[/tex]
[tex]\\ \sf\longmapsto d=\dfrac{W}{F}[/tex]
[tex]\\ \sf\longmapsto d=\dfrac{9}{12}=0.72m[/tex]
Answer:
Anne pushed a cart by 12 N.
● Force = 12 N
Work done is 9 J
● Work = 9 J
=> Work = Force × distance
[tex]=> distance = \frac{work}{force} [/tex]

Answer:
Since I couldn't find the other answers to the same question, I wrote the wrong answer to help ya'll get the sample response. So here's from Edge
Explanation:
Sample Response: If KE = 0, the pendulum is not moving. At the top of the swing, the pendulum must stop for a brief moment.

A canoe is designed to have very little drag when it moves along its length. Riley, mass 62 kg, sits in a 21 kg canoe in the middle of a lake. She dives into the water off the front of the canoe, along the axis of the canoe. She dives forward at 1.7 m/s relative to the boat.
1) Just after her leap, how fast is she moving relative to the water?
2) Just after her leap, how fast is the canoe moving relative to the water?
(1) Riley velocity relative to the water after she jumps is 1.7 m/s.
(2) The velocity of the canoe relative to the water is 5.02 m/s.
The given parameters;
mass of Riley, m₁ = 62 kgmass of canoe, m₂ = 21 kg velocity of the Riley after jumping, v₁ = 1.7 m/s(1) Since the lake is still, her velocity relative to the water after she jumps is 1.7 m/s.
(2) Apply the principle of conservation of linear momentum;
m₁v₁ = m₂v₂
62 x 1.7 = 21v₂
105.4 = 21v₂
[tex]v_2 = \frac{105.4}{21} \\\\v_2 = 5.02 \ m/s[/tex]
Thus, after her leap, the velocity of the canoe relative to the water is 5.02 m/s.

The temperature of the universe has cooled and warmed repeatedly over time.
The temperature of the universe has warmed over time.
The temperature of the universe is the same as it was at the time of the Big Bang.
The temperature of the universe has cooled over time.
The characteristics of the Big Bang allow you to find the correct answers for the different questions are:
1. The galaxies are moving away from each other.
2. There is a large amount of weak background radiation in the universe

The Big Bang model says that initially the universe was born from a great initial explosion about 14 10⁹ years ago, with this idea several facts arise:
The galaxies after their formation must be in a constant expansion There must be an energy in the entire universe remaining from the big explosion As the energy is constant, the energy per unit volume must decrease, consequently the temperature of the universe must be decreasing.
Let's apply these ideas to the different questions, to find the correct answers.
1) What phrase about galaxies provides evidence of the expansion of the universe proposed by the Big Bang
the correct answer is:
The galaxies are moving away from each other.
As there is no friction, the initial forces create a speed in the galaxies, therefore they must move away from each other at this speed
2) What phrases give evidence of the expansion of the universe
the correct answer is:
There is a large amount of weak background radiation in the universe The galaxies are moving away from each other The temperature of the universe is decreasing
3) What evidence of expansion
The temperature of the universe has cooled over time
In conclusion with the characteristics of the Big Bang we can find the correct answers for the different questions are:
1. The galaxies are moving away from each other.
2. There is a large amount of weak background radiation in the universe
The galaxies are moving away from each other The temperature of the universe is decreasing3. The temperature of the universe has cooled over time

A 5.7 kg block slides along a horizontal surface toward a horizontally mounted spring with a spring constant of 150 N/m. At one instant, the block is 5.0 m from the end of the spring and has a speed of 12.0 m/s. If the surface is frictionless, what is the maximum compression of the spring
Hi there!
We can use the conservation of energy:
Ei = Ef
The initial energy involves kinetic energy while the final energy involves maximum elastic potential energy, so:
1/2mv² = 1/2kx²
We can cancel out the 1/2s for ease of solving:
mv² = kx²
Plug in given values to solve for x:
√(mv²/k) = x
√(5.7)(12²)/(150)) = x
x = 2.339 m

If a pool and a cup of water had the same temperature, which would have greater thermal energy?Why?
Despite being the same temperature, the swimming pool is a much larger thermal energy store than the beaker of water.
What is thermal energy?Thermal energy is the energy contained within a system that controls its temperature. The flow of thermal energy is defined as heat.
Thermodynamics is a branch of physics that deals with how heat is transferred between different systems and how work is done in the process.
Thermal energy sources include natural gas, coal, and oil, as well as solar, heat pump electric, and geothermal heat.
A swimming pool and a beaker of water can both be the same temperature.
Despite being the same temperature, the swimming pool contains significantly more thermal energy than the beaker of water. A heated swimming pool's thermal store contains a lot of energy.
Thus, If a pool and a cup of water had the same temperature, then swimming pool has a much larger thermal energy.

A driver spotted a police car and he braked from a speed of 100 km/h to a speed of 80 km/h during a displacement of 88 m at a constant acceleration? What is that acceleration, and how much time is required for the given decrease in speed?
Answer:
Explanation:
100 kph = 27.8 m/s
80 kph = 22.2 m/s
v² = u² + 2as
a = (v² - u²) / 2s
a = (22.2² - 27.8²) / (2(88))
a = -1.578282828...
a = -1.58 m/s²
t negative sign means the acceleration opposes the initial velocity.
t = Δv/a
t = (22.2 - 27.8) / -1.57828
t = 3.52 s
