3. Let the pen return to its vertical position and suddenly pull the thread.
Q4. What happened to the thread tied on the pen?

Answers

Answer 1

Answer:

The thread will experience a force on it .

Explanation:

When thread is tied to pen it will experience force. Because the pen is Abit heavy , there is a force that is applied to it which will cause it to elongate , after a while the thread will stretch, elongate and can later experience deformation. When it experience that, the thread can break after deformation and it has losses it elasticity.

When your blood pressure is low, choose a choice below that explains what occurs.
A. The nervous system signals smooth muscles in the blood vessels to relax to decrease blood pressure.
B. The nervous signals smooth muscles in the blood vessels to relax to increase blood pressure.
C. The nervous system signals smooth muscles to contract to decrease blood pressure.
D. The nervous system signals smooth muscles in the blood vessels to contract to increase blood pressure

Answers

Answer:

The correct option is;

D. The nervous system signals smooth muscles in the blood vessels to contract to increase blood pressure

Explanation:

The contraction or relaxation of the vascular smooth muscles lead to the blood vessel volume change and blood pressure change such that the blood is redirected to regions of the body that requires instantaneous increased oxygen intake. As such the nervous system signals the blood vessel's vascular smooth muscle to contract, through vasoconstriction so as to raise the blood pressure, when the blood pressure is low.

A gas is compressed to 75cm3 to a volume of 30cm3. Its temperature remains the same The pressure of the gas after it has been compressed is 110 Pa. What was the pressure before it was compressed?

Answers

Given parameters:

Initial volume  = 75cm³

New volume  = 30cm³

New pressure  = 110Pa

Unknown:

Initial pressure = ?

Solution:

Condition: temperature is constant

We simply apply Boyle's law to this problem:

   " the volume of a fixed mass(mole) of a gas varies inversely as the pressure changes if the temperature is constant".

  Mathematically;

          P₁ V₁  = P₂ V₂

where P and V are pressure and volume values

          1 and 2 are the initial and final states.

Input the parameters and solve for P₁;

     P₁ x 75  = 110 x 30

   P₁ = 44Pa

         

The initial pressure is 44Pa

To determine the height of a bridge above the water, a person drops a stone and measures the time it takes for it to hit the water. If the time is 2.3 s, what is the height of the bridge? Neglect air resistance.

a. 32 m
b. 52 m
c. 26 m
d. 14 m
e. 10 m

Answers

s = 1/2 a t^2 = 1/2 x 9.8 x 2.3^2 = 26m

A stone dropped from a 26 m bridge, takes 2.3 s to reach the water.

A stone is dropped from a bridge and it experiences a uniformly accelerated rectilinear motion. It takes 2.3 s for the stone to reach the water.

We can calculate the height of the bridge, which is equal to the displacement of the stone, using the following kinematic equation.

[tex]s = ut + \frac{1}{2} a t^{2} = (0m/s)(2.3 s) + \frac{1}{2} (9.8m/s^{2} ) (2.3s)^{2} = 26 m[/tex]

where,

s: displacementu: initial speed (0 m/s)t: timea: acceleration due to gravity (9.8 m/s²)

A stone dropped from a 26 m bridge, takes 2.3 s to reach the water.

Answer:

B and D

Explanation:

Did the quiz

Electromagnetic waves require no wires to carry information and can travel through either air or other types of matter.​ Therefore, options (B) and (D) are correct.

What are electromagnetic waves?

Electromagnetic radiations are produced when an electric field comes in contact with the magnetic field. Electromagnetic waves are the composition of oscillating electric as well as magnetic fields.

Infrared radiation is used in security cameras and used for night vision. UV rays are useful to detect forged banknotes as the real banknotes don’t turn fluorescent under UV light.

Electromagnetic radiation can travel energy in a vacuum or air. Electromagnetic waves play a vital role in today's communication technology. Electromagnetic waves are specially used in RADARS to detect aircraft in the earth's atmosphere.

Radio waves, microwaves, infrared (IR), and visible light can be used for communication. Radio waves are used to transmit information on television and radio programs. Microwaves are used to transmit satellites, mobile phones, and television.

Which statement describes an endothermic reaction? A. Energy is released by the reaction. B. Energy is absorbed by the reaction. C. No energy is transfered by the reaction. D. Energy is created in the reaction. ​

Answers

Answer:It's B energy is absorbed by the reaction,hope this helps

Explanation:

Any reaction in which energy is absorbed is said to be endothermic. Hence, option B is correct, but the rest are not correct.

What is an Endothermic Reaction?

In every chemical process, energy is involved. When new bonds form in products, energy is produced. Reactant bonds are broken using energy. Exothermic reactions are those that produce more energy when new bonds form in the products than is needed to break existing bonds in the reactants.

In contrast, endothermic reactions are the opposite. Endothermic reactions release more energy when new bonds form in the products than is required to break bonds in the reactants.

During the reaction, a large amount of energy is absorbed.

how far will a 600 kg boat travel in 12 s if there is a constant 900 N force on it and it starts from rest?​

Answers

Answer:

Distance, S = 108 meters.

Explanation:

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex] ............equation 1

Where;

F represents force measured in Newton. m represents the mass of an object measured in kilograms. a represents acceleration measured in meters per seconds square.

Given the following data;

Since the boat is starting from rest, initial velocity, u = 0

Mass, m = 600kg

Time, t = 12s

Force, F = 900N

Substituting into equation 1, we have;

[tex] 900 = 600*a[/tex]

[tex]a = \frac{900}{600}[/tex]

Acceleration, a = 1.5 m/s²

T

To solve for distance, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Substituting the values into the equation, we have;

[tex] S = 0(12) + \frac {1}{2}*1.5* 12^{2}[/tex]

[tex] S = 0 + 0.75* 144[/tex]

Distance, S = 108m

Therefore, the distance covered by the boat is 108 meters.

A boy is going down a slide. As he reaches the bottom, friction causes him to slow down and stop. Which one of Newton's laws is this?
2nd law
3rd law
1st law
4th law

Answers

I think it’s the second law

The given condition satisfies the Newton's First Law of motion. Hence, option (C) is correct.

Given data:

A boy slides down and friction causes him to slow down and stop.

In the given problem, when boy was sliding down, then he was in the state of motion, such that the when the he reaches at the bottom of hill, the friction plays the role of external agent to stop its motion.

This shows that the first law of motion is clearly followed which says that, "If an object is in motion, then it will be in motion until and unless any external force is applied on it". This is also known as law of inertia.

Thus, we can conclude that the given condition satisfies the Newton's First Law of motion. Hence, option (C) is correct.

The basket ball is moving at constant speed, this shows that it is not accelerating. So, acceleration is zero

a = 0m/s²

The constant speed is 6m/s

v = 6m/s

So, force to keep it moving with this constant speed can be calculated using Newton second law of motion

F = ma

F = m × 0

F = 0N

So, since the basket ball is moving at constant speed, then, the force need to keep the ball moving is 0N.
