What type of Circuit do they use in a home? WHY ? (Simple circuit / Parallel circuit / Series circuit) helpp
Answers
Answer:
Parallel
Explanation:
Most standard 120-volt household circuits in your home are (or should be) parallel circuits. Outlets, switches, and light fixtures are wired in such a way that the hot and neutral wires maintain a continuous circuit pathway independent from the individual devices that draw their power from the circuit.

what physical properties dose plutonium
Answers
Answer:
Explanation:
Plutonium-239 is one of the two fissile materials used for the production of nuclear weapons and in some nuclear reactors as a source of energy. The other fissile material is uranium-235. Plutonium-239 is virtually nonexistent in nature. It is made by bombarding uranium-238 with neutrons in a nuclear reactor. Uranium-238 is present in quantity in most reactor fuel; hence plutonium-239 is continuously made in these reactors. Since plutonium-239 can itself be split by neutrons to release energy, plutonium-239 provides a portion of the energy generation in a nuclear reactor.

29. A wave source approaches your location, describe
the shift in wavelength and frequency you will
perceive.
Answers
Answer:
The waves travel at the same speed, but the observed frequency depends on any relative motion between the observer and source. When the observed frequency changes, so does the wavelength. If the observer and source are moving toward each other, then the frequency increases and the wavelength decreases.

A 0.144 kg baseball approaches a batter with a speed of 20m/s . The batter lines the ball directly back to the pitcher with a speed of 30m/s . Find the impulse exerted on the ball . If the bat and ball were in contact for 0.012 sec , find the average force exerted on the ball by the bat
Answers
Answer:
The impulse exerted by the ball is 7.2 kg.m/sThe average force exerted on the ball by the bat is 600 N.Explanation:
Given;
mass of the baseball, m = 0.144 kg
velocity of the baseball, v₁ = 20 m/s
velocity of the batter, v₂ = -30 m/s (opposite direction to the ball's speed)
The impulse exerted by the ball is calculated as follows;
J = ΔP = mv₁ - mv₂
ΔP = m(v₁ - v₂)
ΔP = 0.144 [20 - (-30)]
ΔP = 0.144 ( 20 + 30 )
ΔP = 0.144 (50)
ΔP = 7.2 kg.m/s
The average force exerted on the ball by the bat is calculated as;
[tex]F = \frac{\Delta P }{t} \\\\where; t \ is \ time \ of \ contact= 0.012 \ s\\\\F = \frac{7.2}{0.012} \\\\F = 600 \ N[/tex]

Explanation:
Answer:
Explanation: (Momentum is mass * velocity. Its units, in the SI system are kilogram meter per second) What is Inertia?
In physics, momentum is the product of mass and velocity. The greater the product of this equation, the greater the momentum. In science, there are two types of momentum: angular and linear, which concern different types of moving objects. However, that is not where the definition stops. The word momentum is also used as part of everyday speech, and is one of the very few physics concept whose metaphorical definition is the same as its actual one.

Certain specialised devices can be more than 100% efficient. True or false?
Answers
Certain specialized devices can be more than 100% efficient is referred to as a false statement.
What is Efficiency?This is referred to as a way of measuring how much energy can be conserved in a process. On the other hand, energy is the ability to do work and can be lost through various means such as heat.
It is not possible to have an efficiency of 100% because it means that there will be more energy being transferred than what is being supplied which would break the law of conservation of energy and is therefore the reason why false was chosen as the correct choice.

An automobile of mass 1.46 E3 kg rounds a curve of radius 25.0 m with a velocity of 15.0 m/s. The
centripetal force exerted on the automobile while rounding the curve is:
Answers
Answer:
Centripetal force = 13140 Newton.
Explanation:
Given the following data;
Mass = 1.46 E3 kg = 1.46*10³ = 1460 kg
Velocity = 15m/s
Radius, r = 25m
To find the centripetal force, we would use the following formula:
Centripetal force = mv²/r
Substituting into the equation, we have;
Centripetal force = (1460*15²)/25
Centripetal force = (1460 * 225)/25
Centripetal force = 328500/25
Centripetal force = 13140 Newton.
What type of force causes the motion of an object to change
Answers
Answer:
Ok, so...... Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces. In the example below, the net force would be 900 Newtons (450 + 450 = 900), and the object would move to the right.

Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces.

A spring is stretched downward by a certain length and, as a result, exerts a
force in the upward direction. What happens to the force exerted by the
spring if the length by which it is stretched is reduced by half?
O A. The force exerted by the spring is reduced by half.
B. The force exerted by the spring is doubled.
O C. The force exerted by the spring reduced by one quarter.
O D. The force exerted by the spring remains unchanged.
Answers
Answer:
A
Explanation:
Hooke's law! F(spring)=-kx
There's no tricky square law here. The spring constant doesn't change, only x (distance stretched) changes. Therefore, if distance is halved, Force will be halved.

Answers
Answer:
Probable Reason - Break in filament of electric bulb
Explanation:
An electric bulb might not glow even if it is connected to the cell, possibly because of break in the filament of electric bulb. As, break in bulb's filament implies break in flow of electric current - between electric cells' terminal.
An evident example of this is , a fuse bulb doesn't light up as the current doesn't pass through filament.

What is kinetic energy?Kinetic energy is a type of power that a moving object or particle possesses. When an object undergoes work, which involves the transfer of energy, by exerting a net force, the object accelerates and consequently obtains kinetic energy.
Given:
The velocity of the ball, v = 41 m / s,
The mass of the golf ball, m = 0.045 kg,
(1) Calculate the kinetic energy as shown below,
KE = 1 / 2 × 0.045 × 41²
KE = 37.82 Joules
(2) Calculate the kinetic energy of the F-22 jet fighter as shown below,
KE = 1 / 2 × 600² × 100000
KE = 1.8 × 10¹⁰ Joules

Burning fuel in a rocket causes a push that propels the rocket forward from the front. The exhaust gas is pushed rearward in an equal and opposite direction as a result.
What is Newton’s law?The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact.
The following is a paraphrasing of these laws: Unless a force acts upon a body, it remains at rest or in continual straight-line motion.
The creation of thrust by a rocket engine can be understood via Newton's third law. In a rocket engine, a fuel and an oxidizer are burned to produce hot exhaust gas.
The hot exhaust gas from the rocket accelerates to the back of the rocket after passing through the nozzle.
Thus, this way, Newton’s law of action–reaction best be applied to rocket movement.
