What is the relationship between a boats volume and the amount of mass it can hold
Answers
The relationship between a boats volume and the amount of mass is known as Archimedes' principle
Archimedes' principle states that an object displaces its personal weight in a liquid.
So calculate the weight of the boat from the mass. Calculate the quantity of liquid that has this equal weight. that is the quantity of boat underneath the waterline.
Divide that variety with the aid of the vicinity of the boat (duration instances width). this is the depth the boat sinks to.
what is Archimedes principle in easy words?
Archimedes' principle states that a body immersed in a fluid is subjected to an upwards force identical to the burden of the displaced fluid. that is a primary condition of equilibrium. We take into account that the above force, referred to as pressure of buoyancy, is placed in the centre of the submerged hull that we name centre of buoyancy.

The minimum force to start this block moving is ___ N.
Answers
Answer: 14
Explanation:
Force(normal)*coefficient
The static friction force is a force that prevents motion of an object kept on a surface, due to the interaction of the surface of the object and the surface on which it is kept
The minimum force required to start the block moving is 14 NReason:
The known parameter are;
The weight of the block, W = 35 N
The static friction of the surface of the table surface, \(\mu_s\) = 0.40
Required:
To find the minimum force to start the block moving
Solution:
The force required to start the block moving is given by the frictional force that needs to be surpassed
Force required, F = Force of friction
Force of friction = Normal reaction × Coefficient of static friction
On a flat surface, the normal reaction = The weight of the object
∴ Force of friction, \(F_f\) = Weight of the object × Coefficient of static friction
Which gives;
\(F_f = W \times \mu_s\)
\(F_f = 35 \, N \times 0.40 = 14 \, N\)
Force required, F = Force of friction, \(F_f\) = 14 N
The minimum force required to start the block moving, F = 14 N

Energy released by the electron transport chain is used to pump h+ ions into which location.
Answers
Energy released by the electron transport chain is used to pump h+ ions into the mitochondrial inner membrane space.
Describe the process of electron transport?
The last phase of aerobic respiration is electron transport. In this phase, energy from the Krebs cycle products NADH and FADH2 is converted to ATP.Energy from the chemical bonds in glucose is stored at the end of the Krebs Cycle in a variety of energy carrier molecules, including four ATPs, two FADH2 molecules, and ten NADH molecules.Transferring energy from the electron carriers to additional ATP molecules, the "batteries" that power the work within the cell, is the main function of the final step of cellular respiration, the electron transport chain.The electron transport networks employed in photosynthesis are similar to the pathways for ATP generation in stage 3 of aerobic respiration. Energy-carrying electrons cascade from one to another in both electron transport chains, losing a small amount of energy along the way because energy carrier molecules are arranged in a specific order within a membrane.
The electron transport chain, often known as the "respiratory chain," is embedded in the inner membrane of the mitochondria during aerobic respiration. The FADH2 and NADH molecules generated during glycolysis and the Krebs Cycle provide high-energy electrons to energy carrier molecules inside the membrane. In order to pump hydrogen ions into the mitochondrial intermembrane gap and produce an electrochemical gradient, they lose energy as they go from one carrier to another.

Part B
The frequency at the other end of the broadcast band is 0.550 MHz . What is the maximum capacitance of the capacitor if the oscillation frequency is adjustable over the range of the broadcast band?
Answers
Part A:
The inductance of the coil connected to the minimum capacitance of 4.20 pF in the radio is approximately 0.376 μH.
Part B:
The maximum capacitance of the variable capacitor, in order to adjust the oscillation frequency over the broadcast band range, can be calculated as approximately 13.9 pF.
Determine the inductance of the coil?Part A:
To find the inductance of the coil (L) when the minimum capacitance (C) of 4.20 pF is set, we can use the formula for the resonant frequency (f) of an L-C circuit: f = 1 / (2π√(LC)).
Rearranging this formula, we get L = (1 / (4π²f²C)).
Plugging in the values f = 1.66 MHz and C = 4.20 pF,
we can calculate the inductance as L ≈ 0.376 μH.
Determine the maximum capacitance?Part B:
To determine the maximum capacitance (C_max) needed for the variable capacitor in order to adjust the oscillation frequency over the broadcast band range,
we can rearrange the resonant frequency formula as C = 1 / (4π²f²L). Plugging in f = 0.550 MHz and L = 0.376 μH,
we can calculate the maximum capacitance as C_max ≈ 13.9 pF.

what average force is needed to accelerate a 9.20 gram
Answers
The average force needed to accelerate a 9.20 gram object is 0.092 N.
To calculate the average force needed to accelerate a 9.20 gram object, we need to know the acceleration and the time of acceleration. Let's assume that the acceleration and the time of acceleration are not given. Thus, we have to find them using the following equation:
F = ma
Where, F = force (in Newtons)
m = mass (in kilograms)
a = acceleration (in m/s²)
From the question, the mass of the object is given as 9.20 grams = 0.0092 kg. We need to convert it to kilograms to use it in our equation.
m = 0.0092 kg Now, we can find the acceleration of the object.
But, let's assume that the acceleration is given as 10 m/s².
So, a = 10 m/s²
Now, let's use the equation F = ma to find the force needed:
F = ma
F = 0.0092 kg × 10 m/s²
F = 0.092 N
Therefore, the average force needed to accelerate a 9.20 gram object with an acceleration of 10 m/s² is 0.092 N.
The average force needed to accelerate a 9.20 gram object is 0.092 N when the acceleration of the object is 10 m/s². We can find the force using the equation F = ma, where F is force, m is mass, and a is acceleration.The mass of the object is given as 9.20 grams, which is 0.0092 kg when we convert it to kilograms. The acceleration is given as 10 m/s². Therefore, the force needed to accelerate the object can be calculated using the equation:
F = ma
F = 0.0092 kg × 10 m/s²
F = 0.092 N
Thus, the average force needed to accelerate a 9.20 gram object is 0.092 N.
We can say that the average force needed to accelerate a 9.20 gram object can be found using the equation F = ma, where F is force, m is mass, and a is acceleration. If the mass of the object and the acceleration are given, then we can find the force easily. In this case, the mass of the object is 9.20 grams, and the acceleration is 10 m/s². Therefore, the average force needed to accelerate the object is 0.092 N.

The voltage drop is E = I*R
I = 2 amps
R1 = 3 ohms
R1 = 3 ohms
E = 3*2 = 6 volts
The second 3 ohm resistor also has 6 volts across it.
The total is 12 volts so far. But we know nothing more on how to solve for R.

Answers
Answer: Yes. Please find the answer in the explanation.
Explanation:
Yes. Since velocity is a vector quantity, that is, it has both magnitude and direction.
If the displacements covered are not of the same direction, the velocity will not also of the same direction.
Take for instance, if the velocity in a positive is 40 m/s and velocity in the opposite direction is - 20 m/s . Then, the resultant velocity will be 40 - 20 = 20 m/s

Answer:
When you know both the speed and direction of an object's motion, you know the velocity of the object.
When you know both the speed and direction of an object’s motion, you know the magnitude of the speed and direction in which it is moving.
What is Speed ?Speed is a rate of change of distance with respect to time. i.e. v =dx÷dt.
Speed can also be defined as distance over time
i.e. speed= distance ÷ time
it is denoted by v and its SI unit is m/s. it is a scalar quantity. i.e. it has only magnitude not direction. ( velocity is a vector quantity, it has both magnitude and direction. when we define velocity, we should know about its direction)
Speed shows how much distance can be traveled in unit time.
As speed is scalar quantity it has nothing to do with the direction. but when magnitude of speed is given and the direction as well, then we can say that a car or body is moving with this much speed at this direction(east, north, west, south).

Remember: Negative forces (-F) will point Left
Positive forces (+F) will point Right
Answers
The net force on particle q2 can be calculated by finding the net electric force acting on it. The net electric force acting on a particle is the vector sum of the forces exerted by all the other charges on it.
The electric force between two charges q1 and q2 is given by Coulomb's law: F = k * (q1 * q2)/r^2, where k is Coulomb's constant, q1 and q2 are the charges, and r is the distance between them.
The force on particle q2 due to q1 will be:
F1 = k * (q1 * q2) / (0.980m)^2
The force on particle q2 due to q3 will be:
F2 = k * (q2 * q3) / (0.750m)^2
The net force acting on q2 will be the vector sum of F1 and F2.
Keep in mind, q1 and q3 have opposite charges, so they attract each other, while q2 has the same charge as q1, so they repel each other.
Note: The unit of charge is Coulomb (C), but in this problem you are given the charges in microCoulomb (uC) so you need to convert it to Coulomb.
