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.

2 Autonomic Nervous System
3 Sympathetic Division

Answers

Explanation:

1.The somatic nervous system is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. 

2. The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions, such as the heart rate, digestion, respiratory rate, pupillary response, urination, ect...

3. Sympathetic Division is a term used by researchers and medical practitioners to describe the subdivision of the autonomic nervous system (that controls involuntary and automatic physical reactions) that responds to emergency situations by mobilizing and controlling the energy necessary to cope with the situation.

4. The part of the autonomic nervous system that tends to act in opposition to the sympathetic nervous system, as by slowing down the heart and dilating the blood vessels. It also regulates the function of many glands, such as those that produce tears and saliva.

5. a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action.

How can Newton’s law of action–reaction best be applied to explain the movement of a rocket?

Answers

Answer:As the fuel burns,gases push against the rocket, moving it upward

Explanation: here’s a tip download socratic take a pic of the question then scroll down there should be a quizzes with the answer for you quizzes is good when you want answers to a Science or language arts/reading so yea

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.

What is momentum? And it’s types?

Answers

Answer:

Momentum is the product of mass and velocity. The two types of momentum are angular and linear.

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.

What is the speed of a 180 g ball if its kinetic energy is 100 J?

Answers

Answer:

Velocity, V = 33.33 m/s

Explanation:

Given the following data;

Mass = 180grams to kilograms = 180/1000 = 0.18 kg

Kinetic energy = 100J

To find the speed;

Kinetic energy can be defined as an energy possessed by an object or body due to its motion.

Mathematically, kinetic energy is given by the formula;

[tex] K.E = \frac{1}{2}MV^{2}[/tex]

Where;

K.E represents kinetic energy measured in Joules.

M represents mass measured in kilograms.

V represents velocity measured in metres per seconds square.

Substituting into the equation, we have;

100 = ½*0.18*V²

Cross-multiplying, we have;

200 = 0.18*V²

V² = 200/0.18

V² = 1111.11

Taking the square root of both sides, we have;

Velocity, V = 33.33 m/s

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.

Explanation:

Answer:

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.

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]

An object is moving to the right at a constant velocity. What will happen if a
force of 20 N starts acting on it in the opposite direction?
А
The object's velocity will increase.
B
The object's velocity will decrease.

The object will come to a stop.
D
The object will move at the same velocity.
