Answer:
The current would increase.
Explanation:
The current would increase. 10. The relationship between resistance and current in a circuit is that the greater the resistance the less the current and the greater the current the less the resistance is.
if a 1.5-volt battery is removed and placed by a 9-volt battery in a circuit, From Ohm's law we can say that the current flow inside the circuit will increase because the voltage increases (resistance remains constant).
What is Ohm's law?Ohm's Law is a fundamental law of physics that describes the relationship between the three basic electrical quantities: voltage, current, and resistance in a circuit.
It states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them. Mathematically, Ohm's Law is expressed as:
V = I x R
Where:
V = the voltage or potential difference between two points in the circuit, measured in volts (V).
I = the current flowing through the circuit, measured in amperes (A).
R = the resistance of the conductor, measured in ohms (Ω).
In other words, the voltage (V) across a circuit component is equal to the product of the current (I) flowing through the component and its resistance (R). This law is applicable to both DC (direct current) and AC (alternating current) circuits, as long as the resistance is constant.
Ohm's Law can be used to calculate any one of the three variables if the other two are known. For example, if the voltage and resistance in a circuit are known, the current flowing through the circuit can be calculated using the formula:
I = V / R
Here in the question,
The current in a circuit is determined by the resistance of the circuit and the voltage applied to it, according to Ohm's Law. If a 9-volt battery replaces a 1.5-volt battery, the voltage applied to the circuit will increase, which may cause an increase in the current flowing through the circuit if the resistance remains the same.
However, the increase in voltage may also cause an increase in the heat generated by the circuit, which could potentially damage the components or cause a safety hazard. Therefore, it is important to ensure that the components in the circuit can handle the higher voltage before replacing the battery.
It's also important to note that the current may also depend on the internal resistance of the batteries. A 9-volt battery typically has a lower internal resistance than a 1.5-volt battery, which means it can supply more current to the circuit. So, even if the resistance of the circuit remains the same, the current may still increase due to the higher voltage and lower internal resistance of the 9-volt battery.
Hence, The current flowing through the circuit increased when we removed a 1.5-volt battery and replaced it with a 9-volt battery.

Humans have both main and secondary needs that must be met in order for them to feel needed. These requirements naturally nudge a person in that direction. Hunger, thirst, and a desire for sexual activity are examples of fundamental wants. Secondary needs, on the other hand, are those that depend on advantages, with financial requirements serving as the finest illustration.

What is required to start an object moving?
To start an object moving, a force must be applied to the object which must be greater than the forces that are acting to keep the object at rest.
The amount of force needed to start an object moving depends on the mass of the object, as well as the type and magnitude of the forces acting on it. For example, it may take more force to start a heavy object moving than a light object, and it may take more force to start an object moving on a rough or slippery surface than on a smooth or sticky surface.
To apply a force to an object, we can push or pull on it, use a lever or other mechanical advantage to amplify the force, or use an external force such as gravity or a motor to move the object. Once the object is moving, it will continue to move unless acted upon by another force.

What is kinetic energy?In physics, the kinetic energy of an object is the energy it has due to its motion. It is defined as the work required to accelerate a body of specified mass from rest to a specified velocity. After the body acquires this energy during acceleration, it retains this kinetic energy as long as the velocity does not change. The same work is done when the body slows down from its current speed to rest. Formally, kinetic energy is any term in the Lagrange of a system that includes the time derivative.
According to question:In this problem, neglecting friction force, there are two energies at work viz. Potential energy of spring and kinetic energy of spring mass system.
Initially the spring is compressed to length from the equilibrium position, therefore, initially,
Potential energy= 1/2KX²
(Because potential energy of spring= 1/2×(spring constant)×(compression)²)
At this instance system is at rest, therefore, kinetic energy=1/2mv²=0.
So total initial energy= K.E. + P.E. = 1/2KX² -(1)
Now in the 2nd instant, spring is compressed to length from equilibrium, therefore, P.E.=1/2K ²
and velocity= here,
Therefore, kinetic energy= 1/2 mv²
So total energy= 1/2K ² + 1/2 m² -(2)
From conversation of energy theorem, (1) and (2) should be equal(Neglecting friction, remember)
Therefore, the correct answer is: 1/2KX²= 1/2KXf ² + 1/2Vf m²

The separation of the plates in this parallel-plate capacitor is approximately 6.49 micrometers.
The separation of the plates in a parallel-plate capacitor can be calculated using the equation:

the (nonconservative) force propelling a 1.50 x 103 kg car up a mountain road does 4.70 x 106 j of work on the car. the car starts from rest at sea level and has a speed of 27.0 m/s at an altitude of 2.00 x 102 m above sea level. calculate the work done on the car by the combined forces of friction and air resistance, both of which are nonconservative forces.
Work done by friction and air resistance -780,000 Joules. Since the work done by the combined forces of friction and air resistance is negative, this means that these forces are doing negative work on the car, which means that they are slowing the car down.
The work done on the car by the force propelling it up the mountain road is given by W = Fd, where F is the force and d is the distance over which the force is applied. Since the force is nonconservative, the work it does on the car is not equal to the change in the car's kinetic energy. Instead, the work done by the force propelling the car is equal to the change in the car's potential energy plus the work done by the nonconservative forces of friction and air resistance.
To find the work done by the combined forces of friction and air resistance, we can use the following equation:
Work done by friction and air resistance = change in kinetic energy - change in potential energy
We can find the change in the car's kinetic energy by subtracting its initial kinetic energy (0 Joules, since it starts from rest) from its final kinetic energy. The final kinetic energy of the car is given by
[tex]KE = \frac{1}{2} mv^2[/tex]
where m is the mass of the car and v is its speed. Plugging in the values, we get:
[tex]KE = (1/2)(1.50 * 103 kg)(27.0 m/s)^2 = 2.16 * 105[/tex] joule
The change in the car's potential energy can be found by subtracting its initial potential energy (which is 0 Joules at sea level) from its final potential energy. The final potential energy of the car is given by
PE = mgh,
where m is the mass of the car, g is the acceleration due to gravity, and h is the height of the car above the ground. Plugging in the values, we get:

S.G is specific gravity of the solid wooden sphere¹/₂ = ρ / (800 kg/m³)
ρ = ¹/₂ x 800 kg/m³
ρ = 400 kg/m³
The mass of the solid wooden sphere is calculated as;
m = density x volume
m = 400 kg/m³ x 0.01 m³
m = 4 kg
The tension in the cord is calculated as follows;
T = W = mg
T = 4 kg x 9.8 m/s²
T = 39.2 N
Thus, the tension in cord is equal to the weight of the solid wooden sphere submerged in the liquid.
